Question 1Collaboration Infrastructure and Design

In a Cisco collaboration deployment, which protocol is used by an endpoint to register with Cisco Unified Communications Manager and to receive call-control signaling?

  1. SIP Correct answer.
  2. MGCP
  3. SCCP
  4. H.323

Explanation

Cisco Unified Communications Manager uses SIP as its primary line-side and trunk-side signaling protocol, and endpoints register over SIP to receive call control. H.323 and MGCP are gateway control protocols, and SCCP is used only by legacy Skinny endpoints rather than being the modern default registration protocol.

Question 2Collaboration Infrastructure and Design

Which Cisco component provides centralized call admission control for a multisite collaboration deployment using a hub-and-spoke WAN topology?

  1. Cisco Unified Communications Manager locations Correct answer.
  2. Cisco Expressway-C
  3. Cisco Prime Collaboration Provisioning
  4. Cisco Unified Border Element

Explanation

CUCM locations implement centralized call admission control by limiting the amount of bandwidth available between locations for calls traversing the WAN. Expressway-C handles firewall traversal and MRA, Unified Border Element handles SIP trunking between networks, and Prime Collaboration handles provisioning rather than admission control.

Question 3Collaboration Infrastructure and Design

A design requires that remote workers use their Jabber clients without a full VPN while registering to on-premises CUCM. Which solution satisfies this requirement?

  1. Cisco Expressway-C and Expressway-E with Mobile and Remote Access Correct answer.
  2. Cisco Unified Border Element with SIP early offer
  3. CUCM locations with a dedicated location for remote workers
  4. Cisco Meeting Server with a reverse proxy

Explanation

Mobile and Remote Access pairs Expressway-C inside the network with Expressway-E in the DMZ to allow Jabber registration and call signaling without a VPN. The other options address SIP trunking, bandwidth admission control, or conferencing rather than secure remote registration.

Question 4Collaboration Infrastructure and Design

Which codec is mandatory for all SIP endpoints in a Cisco collaboration deployment to guarantee baseline interoperability?

  1. G.711 mu-law Correct answer.
  2. G.722
  3. Opus
  4. iLBC

Explanation

G.711 mu-law is the mandatory baseline codec for SIP endpoints and is used as the fallback when no other codec is negotiated. G.722, Opus, and iLBC are optional codecs that improve quality or compression but are not guaranteed across all endpoints.

Question 5Collaboration Infrastructure and Design

Which protocol does Cisco Unified Communications Manager use to control analog and digital voice gateways in a centralized deployment?

  1. SCCP
  2. H.323
  3. SIP
  4. MGCP Correct answer.

Explanation

MGCP is a gateway control protocol in which CUCM acts as the call agent and instructs the gateway to create, modify, and delete connections. SIP and H.323 are peer signaling protocols, and SCCP is used for Skinny client endpoints, not gateway control in this design.

Question 6Collaboration Infrastructure and Design

Which Cisco component is required to interconnect a Cisco collaboration deployment to a service provider SIP trunk when topology hiding and media interworking are needed?

  1. Cisco Expressway-E
  2. Cisco Unified Communications Manager SIP trunk
  3. Cisco Unified Border Element Correct answer.
  4. Cisco TelePresence Management Suite

Explanation

The Cisco Unified Border Element is a session border controller that provides topology hiding, media interworking, and demarcation between the enterprise and a service provider SIP trunk. Expressway-E handles remote access, and a direct CUCM SIP trunk lacks the interworking and security functions of a session border controller.

Question 7Collaboration Infrastructure and Design

Which Cisco technology allows a single dial plan to route calls across multiple clusters while providing centralized numbering normalization?

  1. Cisco Unified Border Element
  2. Cisco Unified SIP Proxy Correct answer.
  3. Cisco Emergency Responder
  4. Cisco Unified Communications Manager with intercluster trunks

Explanation

Cisco Unified SIP Proxy provides centralized routing and normalization of SIP requests across clusters and SIP networks. Intercluster trunks connect clusters directly but do not centralize normalization, and the other options provide SBC or emergency services functions.

Question 8Collaboration Infrastructure and Design

Which feature allows CUCM to provide dial tone and call control to endpoints at a remote site over a WAN link that may be congested?

  1. Cisco Unified Survivable Remote Site Telephony in a gateway
  2. Survivable Remote Site Telephony Correct answer.
  3. Cisco Expressway MRA
  4. CUCM locations

Explanation

Survivable Remote Site Telephony, often implemented in a gateway router, allows remote-site endpoints to register to a local call-control process when the WAN to CUCM is unavailable. Locations only limit bandwidth and do not provide local call control, and MRA addresses remote access rather than WAN survivability.

Question 9Collaboration Infrastructure and Design

A company wants to deploy a hub-and-spoke collaboration topology with a single CUCM cluster at headquarters. Which two design elements are most important for ensuring voice quality across the WAN? (Choose the best single answer.)

  1. Full mesh MPLS with no QoS
  2. Overprovisioning the WAN by 10 percent
  3. Using G.729 exclusively at all sites
  4. QoS marking and call admission control Correct answer.

Explanation

Voice quality across a WAN depends on QoS to prioritize voice and call admission control to prevent oversubscription of the link. Full mesh without QoS, modest overprovisioning, or codec choice alone cannot guarantee quality when the link is congested.

Question 10Collaboration Infrastructure and Design

An engineer needs to allow video endpoints to call across a cluster boundary while preserving bandwidth admission control. Which design approach is most appropriate?

  1. Configure a SIP trunk without locations and rely on QoS
  2. Configure intercluster trunks and locations with bandwidth limits for the intercluster link Correct answer.
  3. Deploy Cisco Expressway-E only
  4. Use H.323 trunks between clusters

Explanation

Intercluster trunks carry calls between clusters, and locations apply bandwidth admission control to those calls when the intercluster link is associated with a location. A SIP trunk without locations, Expressway-E alone, or H.323 trunks do not provide the required bandwidth admission control.

Question 11Collaboration Infrastructure and Design

A customer requires that PSTN calls from a branch gateway use a specific calling number. Which gateway configuration element is used to modify the calling party number before the call leaves the gateway?

  1. Device pool
  2. Calling party transformation Correct answer.
  3. Translation pattern
  4. Route group

Explanation

Calling party transformation settings on the gateway or trunk modify the calling number as the call exits, which is the correct tool for presenting a specific number to the PSTN. Translation patterns transform dialed digits, route groups select gateways, and device pools group device settings.

Question 12Collaboration Infrastructure and Design

An administrator wants to prevent toll fraud by restricting which external numbers can be dialed from certain devices. Which CUCM mechanism is best suited for this?

  1. Regions
  2. Locations
  3. Partitions and calling search spaces Correct answer.
  4. Device pools

Explanation

Partitions and calling search spaces control which dialed patterns a device is allowed to reach by limiting the partitions included in its calling search space. Device pools group settings, regions control codec selection, and locations control bandwidth admission.

Question 13Collaboration Infrastructure and Design

A design uses a centralized CUCM cluster with SRST at branch sites. Which statement describes the correct behavior when the WAN link fails?

  1. The phones fail over to Expressway-E for call control
  2. The branch gateway registers the phones and provides basic call control using its configured SRST dial peers Correct answer.
  3. The phones remain registered to CUCM and calls continue over the failed WAN
  4. CUCM locations automatically reroute calls to the PSTN

Explanation

When the WAN fails, SRST on the branch gateway detects loss of CUCM and allows local phones to register to the gateway, which provides basic call control using its dial peers. Phones cannot remain registered across a failed WAN, Expressway-E is not a call-control fallback, and locations do not reroute calls.

Question 14Collaboration Infrastructure and Design

Which codec should be selected for a link where bandwidth is constrained but voice quality must remain acceptable, and where the design allows compression?

  1. Opus at 64 kbps
  2. G.722
  3. G.711
  4. G.729 Correct answer.

Explanation

G.729 compresses voice to 8 kbps, making it suitable for constrained links while maintaining acceptable quality. G.711 and G.722 consume significantly more bandwidth, and Opus at 64 kbps offers no bandwidth advantage over G.711.

Question 15Collaboration Infrastructure and Design

An engineer must ensure that calls between two regions use G.729 while calls within a region use G.722. Which CUCM configuration achieves this?

  1. Configure locations with G.729 bandwidth
  2. Use device pools with G.722 only
  3. Set the cluster-wide codec to G.729
  4. Assign devices to regions and set the region pair codec to G.729 between the two regions Correct answer.

Explanation

Regions define which codecs are used between devices in different regions, and region pairs can be configured with a specific codec such as G.729. A cluster-wide codec setting, locations bandwidth, or device pools alone do not provide per-region-pair codec selection.

Question 16Collaboration Infrastructure and Design

Which protocol is used between CUCM and Cisco Expressway-C for Mobile and Remote Access?

  1. H.323
  2. SIP over TLS Correct answer.
  3. MGCP
  4. RTP

Explanation

Expressway-C and Expressway-E use SIP over TLS for call signaling in Mobile and Remote Access, with media traversing the traversal zone. H.323 and MGCP are not used for MRA call signaling, and RTP carries media rather than signaling.

Question 17Collaboration Infrastructure and Design

A company wants to deploy a SIP trunk to a service provider that requires early media and PRACK. Which CUCM SIP profile setting should be verified?

  1. Enable 100rel support in the SIP profile Correct answer.
  2. Set the DTMF signaling method to OOB
  3. Enable URI dialing
  4. Disable MTP

Explanation

PRACK and reliable provisional responses require 100rel support, which is enabled in the SIP profile used by the trunk. Disabling MTP, changing DTMF signaling, or enabling URI dialing do not provide reliable provisional response support.

Question 18Collaboration Infrastructure and Design

Which statement best describes the role of a route list in a CUCM dial plan?

  1. It defines the dialed digit patterns
  2. It limits bandwidth for a location
  3. It assigns codecs between regions
  4. It selects among route groups in a defined order to reach a destination Correct answer.

Explanation

A route list references one or more route groups and selects among them in priority order to route a call. Dialed digit patterns are defined by route patterns, codecs are set by regions, and bandwidth is limited by locations.

Question 19Collaboration Infrastructure and Design

A design requires that a Cisco collaboration solution support 10,000 endpoints with high availability across two data centers. Which deployment model is most appropriate?

  1. Two independent clusters with no intercluster trunk
  2. A standalone CUCM publisher with no subscribers
  3. A single CUCM cluster with nodes distributed across both data centers Correct answer.
  4. A single CUCM cluster with two subscriber nodes in one data center

Explanation

A single cluster with nodes distributed across both data centers provides high availability and redundancy while maintaining a single dial plan. A single data center, two isolated clusters, or a standalone publisher without subscribers do not satisfy the high-availability requirement.

Question 20Collaboration Infrastructure and Design

Which Cisco component provides centralized management and provisioning of collaboration endpoints and users across multiple clusters?

  1. Cisco Expressway-C
  2. Cisco Unified Border Element
  3. Cisco Prime Collaboration Provisioning Correct answer.
  4. Cisco Unified SIP Proxy

Explanation

Cisco Prime Collaboration Provisioning provides centralized user and device provisioning across clusters. Unified Border Element handles SIP interworking, Expressway-C handles remote access, and Unified SIP Proxy handles routing.

Question 21Collaboration Infrastructure and Design

An engineer observes that calls between two clusters fail because the codec negotiated is not supported by the intercluster trunk. Which configuration is most likely the cause?

  1. The region pair between the clusters is configured with a codec not supported by the trunk Correct answer.
  2. The route group has no route list
  3. The device pool is missing a location
  4. The SIP profile has URI dialing disabled

Explanation

Intercluster trunk codec selection is governed by the region pair between the clusters; if that pair specifies an unsupported codec, negotiation fails. Missing locations, route group ordering, and URI dialing settings do not determine the codec used on the trunk.

Question 22Collaboration Infrastructure and Design

A customer requires that remote Jabber clients use a single URL for internal and external access while maintaining security. Which Expressway configuration supports this?

  1. Use H.323 on the traversal zone
  2. Use separate URLs for internal and external clients
  3. Disable TLS on the traversal zone
  4. Configure the same discovery URL for internal and external DNS resolution Correct answer.

Explanation

Mobile and Remote Access supports a single discovery URL that resolves differently for internal and external clients, allowing consistent client configuration while maintaining security. Separate URLs, disabling TLS, or using H.323 do not meet the requirement.

Question 23Collaboration Infrastructure and Design

An engineer must design a dial plan that prevents overlapping dial patterns while supporting both 4-digit internal extensions and 10-digit PSTN numbers. Which approach is most appropriate?

  1. Use a single catch-all route pattern for all calls
  2. Configure only 4-digit extensions and block all PSTN calls
  3. Use partitions and calling search spaces with specific route patterns and translation patterns to normalize digits Correct answer.
  4. Rely on the PSTN gateway to resolve all dialed digits

Explanation

Partitions, calling search spaces, specific route patterns, and translation patterns normalize digits and prevent overlap between internal and PSTN dialing. A catch-all pattern creates ambiguity, gateway resolution is unreliable, and blocking PSTN calls does not meet the requirement.

Question 24Collaboration Infrastructure and Design

A design requires that voice traffic be marked and queued correctly across a WAN with multiple classes of service. Which approach is most appropriate?

  1. Mark voice as EF and place it in a priority queue with admission control Correct answer.
  2. Mark voice as AF41 and place it in a class-based queue
  3. Mark voice as best effort and rely on overprovisioning
  4. Mark voice as CS1 and use weighted fair queuing

Explanation

Voice should be marked EF and placed in a low-latency priority queue, with call admission control preventing oversubscription of that queue. AF41 is used for interactive video, best effort provides no protection, and CS1 is a lower priority marking.

Question 25Collaboration Infrastructure and Design

A company is designing a collaboration solution that must support both on-premises and cloud calling with a consistent dial plan. Which Cisco architecture is most appropriate?

  1. Cisco Meeting Server only
  2. Cisco Unified Communications Manager with Webex Calling via a supported PSTN and dial plan integration Correct answer.
  3. A standalone CUCM cluster with no external connectivity
  4. Cisco Emergency Responder only

Explanation

Integrating CUCM with Webex Calling through supported PSTN connectivity and dial plan integration allows a consistent numbering scheme across on-premises and cloud calling. A standalone cluster, Meeting Server, or Emergency Responder alone cannot provide combined on-premises and cloud calling.

Question 26Collaboration Infrastructure and Design

In a centralized Cisco collaboration deployment, which function does the Cisco Unified Border Element (CUBE) provide at the edge toward an ITSP SIP trunk?

  1. Media termination point that transcodes all calls to G.722 for internal endpoints
  2. Back-to-back user agent that terminates and re-originates signaling and media between dissimilar SIP domains Correct answer.
  3. Directory synchronization gateway that replicates LDAP users into CUCM
  4. Call admission control engine that computes WAN bandwidth per region

Explanation

CUBE is a session border controller built on IOS-XE that acts as a back-to-back user agent, terminating the enterprise-side SIP dialog and creating a separate dialog toward the provider. This demarcation enables topology hiding, header normalization, codec and DTMF interworking, and security policy enforcement. It is not the call admission control or directory replication function of the cluster.

Question 27Collaboration Infrastructure and Design

A cluster uses a single route group containing two SIP trunks to the same provider. Which statement describes how CUCM distributes calls across those trunks?

  1. It uses the trunk whose device pool matches the calling device's device pool
  2. It selects the trunk with the lowest administrative preference value for every call
  3. It sends all calls to the first trunk until that trunk is manually disabled
  4. It load-balances each call in round-robin order across the trunks in the route group Correct answer.

Explanation

Within a route group CUCM distributes calls across member trunks using a round-robin algorithm so that outbound load is shared. Ordering of route groups inside a route list is what provides primary and backup paths, not load sharing within a route group. Device pool matching is not a trunk selection criterion.

Question 28Collaboration Infrastructure and Design

Which protocol and port pair does a Cisco Expressway-E use to receive Mobile and Remote Access signaling from external Jabber clients?

  1. HTTPS over TCP 443 Correct answer.
  2. SIP over TLS 5061
  3. SIP over TCP 5060
  4. HTTPS over TCP 8443

Explanation

Mobile and Remote Access publishes the Expressway-E traversal zone to the internet over HTTPS on TCP 443, which carries the reverse-proxy traffic for registration, provisioning, and signaling. SIP/TLS 5061 is used between Expressway-C and Expressway-E across the traversal zone, not by external clients. Keeping client access on 443 also simplifies firewall traversal.

Question 29Collaboration Infrastructure and Design

A design must keep branch voice traffic usable when the WAN is congested. Which marking and queuing approach is correct for Cisco collaboration endpoints?

  1. Mark voice payload EF and call signaling CS3, then place them in a priority queue with policers for excess Correct answer.
  2. Mark all collaboration traffic AF41 and queue it in a single fair-queue class
  3. Mark voice payload CS1 and signaling AF11, relying on weighted random early detection
  4. Mark voice payload EF and signaling EF, then place both in one priority queue

Explanation

Cisco collaboration QoS baseline marks voice media EF (DSCP 46) and call signaling CS3 (DSCP 24), with video conferencing marked AF41. Voice media is served by a low-latency priority queue that is policed so it cannot starve other classes, while signaling gets guaranteed bandwidth in a separate class. Collapsing media and signaling into one queue loses that separation.

Question 30Collaboration Infrastructure and Design

Which statement describes the role of a SIP trunk security profile on a CUCM cluster?

  1. It sets the region and location pair used for bandwidth accounting on the trunk
  2. It assigns codec preferences to every call that traverses the trunk
  3. It controls which TLS cipher suites, digest authentication, and incoming port are accepted for a SIP trunk Correct answer.
  4. It defines digest credentials that CUCM presents to an external registrar

Explanation

A SIP trunk security profile is applied to the trunk and governs transport security behavior: whether TLS is used, which cipher suites are offered, whether digest authentication is enabled, and the listening port. Codec policy and bandwidth accounting come from regions, locations, and SIP profiles, not the security profile.

Question 31Collaboration Infrastructure and Design

An engineer must ensure that a branch Cisco ISR gateway registers its POTS endpoints to a centralized CUCM cluster over the WAN. Which two elements are required on the gateway and cluster respectively?

  1. Skinny Client Control Protocol endpoint registration and a transcoder resource
  2. MGCP gateway configuration on CUCM and an SRST reference on the gateway Correct answer.
  3. H.323 gateway definition on CUCM and a gatekeeper zone on the gateway
  4. SCCP gateway definition on CUCM and a DSP farm on the gateway

Explanation

Centralized gateway control uses MGCP, so the gateway is configured with the MGCP commands and CUCM holds a matching MGCP gateway definition with endpoint identifiers for each voice port. SRST must also be configured on the gateway so local endpoints retain service if the WAN to the cluster fails. H.323 or SCCP gateway definitions do not provide the same centralized endpoint-level control.

Question 32Collaboration Infrastructure and Design

Which capability does the Cisco Unified CM IM and Presence Service add to a collaboration deployment?

  1. It performs call admission control across clusters using locations
  2. It hosts the voicemail store and message waiting indication for the cluster
  3. It supplies presence status, instant messaging, and XMPP federation to Jabber clients Correct answer.
  4. It provides the SIP registrar that authenticates desk phone registrations

Explanation

The IM and Presence Service is a separate cluster that provides presence, instant messaging, and XMPP federation for Jabber and other clients, while CUCM remains the call control and SIP registrar. Presence is derived from phone status and user activity and is shared with clients through the presence engine. Voicemail and admission control are functions of other components.

Question 33Collaboration Infrastructure and Design

A customer wants the same dialed digits to reach a branch extension in one site and a different extension in another site, with no overlap. Which dial plan technique best achieves this?

  1. Assign each site a unique site code prefix and build site-specific route patterns Correct answer.
  2. Rely on translation patterns that strip all digits before routing
  3. Use a single flat ten-digit pattern for all internal extensions
  4. Configure a global dial plan with no partitions or calling search spaces

Explanation

Unique site codes create a structured, hierarchical numbering plan so that each site's extensions are addressable without ambiguity, and route patterns can direct the correct prefix to the correct site. A flat ten-digit scheme or a plan without partitions and calling search spaces removes the ability to scope which users can reach which destinations. Stripping all digits destroys the routing information.

Question 34Collaboration Infrastructure and Design

Which statement describes the difference between a CUCM region and a CUCM location?

  1. A region defines the SIP profile for trunks, and a location defines the security profile for trunks
  2. A region defines bandwidth limits for calls, and a location defines codec policy between device pools
  3. A region defines the time zone for devices, and a location defines the device pool membership
  4. A region defines codec policy between device pools, and a location defines bandwidth limits for calls Correct answer.

Explanation

Regions determine which codec is used between devices in different device pools, while locations (or enhanced locations) enforce call admission control by limiting the bandwidth available for calls between them. The two are independent: a region controls media format, a location controls how much media is admitted. Time zone and trunk profile settings are unrelated attributes.

Question 35Collaboration Infrastructure and Design

An engineer must design a cluster that supports 20,000 registered endpoints with redundancy if a single subscriber fails. Which cluster design meets the requirement?

  1. A single subscriber per site with SRST providing all failover within the site
  2. A single large Cisco Unified CM appliance with no additional nodes
  3. Multiple subscribers with device pools assigning a primary and backup server per device Correct answer.
  4. One publisher and one subscriber, with all phones registering to the publisher

Explanation

Scalability and redundancy in a CUCM cluster come from deploying multiple subscriber nodes and assigning each device a primary and backup Cisco Unified CM through its device pool, so registration moves automatically if a node fails. A single publisher or single appliance provides no failover, and SRST is a branch survivability mechanism rather than in-cluster redundancy.

Question 36Collaboration Infrastructure and Design

A design uses a Cisco Expressway pair for business-to-business calling. Which element on the Expressway is required to allow calls to an external SIP domain?

  1. A neighbor zone toward the external domain with the appropriate SIP settings
  2. A default zone configured with a search rule that matches the external domain Correct answer.
  3. A traversal zone between the two Expressway-C nodes
  4. A DNS zone that resolves the external domain to internal endpoints

Explanation

Search rules in the default zone determine which calls are permitted and which zone or target they are sent to; a rule matching the external domain and pointing to the appropriate neighbor or traversal target enables the business-to-business call. Neighbor zones themselves only describe how to reach a peer, and traversal zones are for firewall traversal between C and E. A DNS zone is used for DNS-based dialing lookups, not for permitting an external domain.

Question 37Collaboration Infrastructure and Design

Which Cisco component centralizes provisioning of phones, users, and dial-plan elements for an on-premises collaboration deployment?

  1. Cisco Unity Connection
  2. Cisco Expressway-C
  3. Cisco Unified Communications Manager Correct answer.
  4. Cisco Prime Collaboration Provisioning

Explanation

Cisco Unified Communications Manager is the call-control cluster that holds device, user, and dial-plan configuration and pushes that configuration to registered endpoints. Unity Connection provides messaging, Expressway provides edge and MRA services, and provisioning tools automate bulk changes but rely on CUCM as the system of record.

Question 38Collaboration Infrastructure and Design

A design must support a consistent dial plan across an on-premises CUCM cluster and a Webex Calling deployment. Which approach provides a shared, normalized numbering scheme?

  1. Rely on the PSTN provider to translate all numbers between the systems
  2. Assign random extensions and rely on user speed dials for cross-system calls
  3. Configure each system with an independent, unrelated numbering plan
  4. Use a global dial plan with standardized E.164 numbers and normalization at each edge Correct answer.

Explanation

A global dial plan uses E.164 as the common canonical form, with normalization applied at each system's edge so that digits are converted consistently before routing. This lets on-premises and cloud users reach each other and the PSTN through predictable patterns. Independent numbering plans or provider-side translation create ambiguity and inconsistent reachability.

Question 39Collaboration Infrastructure and Design

Which statement describes how enhanced locations differ from classic locations for call admission control in CUCM?

  1. Enhanced locations require the Expressway to perform admission control
  2. Enhanced locations count only audio streams and ignore video
  3. Enhanced locations support video bandwidth accounting and per-location video call limits Correct answer.
  4. Enhanced locations replace regions and define codec policy

Explanation

Enhanced locations extend classic locations by accounting for video bandwidth in addition to audio and by allowing per-location limits on the number of video calls. Classic locations count only audio bandwidth between locations. Regions still define codec policy, and Expressway-based admission control is a separate mechanism used with MRA.

Question 40Collaboration Infrastructure and Design

An engineer must configure a SIP trunk so that CUCM sends calls to the provider with a normalized calling number. Which two configuration elements are typically used together?

  1. A calling party transformation pattern and the trunk's calling search space Correct answer.
  2. A route group and a media resource group list on the trunk
  3. A SIP profile and a security profile on the trunk
  4. A device pool and a region assignment on the trunk

Explanation

Calling party transformation patterns rewrite the calling number, and the trunk's calling search space determines which transformation patterns the trunk can apply on outbound calls. Together they ensure the provider receives the required normalized format. Media resource groups, device pools, regions, and security profiles do not transform the calling number.

Question 41Collaboration Applications and Services

Which Cisco collaboration application provides a standards-based, on-premises instant messaging and presence service that can federate with other XMPP domains using SIP or XMPP interdomain links?

  1. Cisco Emergency Responder
  2. Cisco Unified Communications Manager IM and Presence Service Correct answer.
  3. Cisco Unity Connection
  4. Cisco Prime Collaboration Provisioning

Explanation

IM and Presence Service is the Cisco on-premises presence and instant messaging platform built on XMPP, and it supports interdomain federation with remote domains over SIP or XMPP. Emergency Responder handles E911 location, Unity Connection handles voicemail, and Prime Collaboration Provisioning handles provisioning automation.

Question 42Collaboration Applications and Services

In Cisco Unity Connection, which object groups users together so that a caller can dial one number and reach every member's mailbox in sequence or in parallel?

  1. Partition
  2. Search scope
  3. Distribution list Correct answer.
  4. Hunt pilot

Explanation

A distribution list in Unity Connection is a container of users or contacts that can be dialed as a single destination, letting callers leave a message for all members or dispatch to the first available member. Search scopes and partitions control dialing visibility, and hunt pilots live in Unified Communications Manager.

Question 43Collaboration Applications and Services

Which protocol does Cisco Unified Communications Manager use to deliver call-control events to a Cisco IP Phone Services application that subscribes to phone state?

  1. SNMP traps from the CallManager service
  2. Cisco TAPI/JTAPI via CTIManager Correct answer.
  3. SIP SUBSCRIBE/NOTIFY with dialog events
  4. HTTP SOAP with WS-Security

Explanation

Applications that need call-control awareness, such as screen pops or phone-state services, subscribe through CTIManager using TAPI or JTAPI. SIP dialog events are used for line-state presence to phones, not for application call-control event delivery.

Question 44Collaboration Applications and Services

A Cisco Expressway-E sits in the DMZ and must traverse a firewall to reach Cisco Expressway-C in the internal network. Which transport is recommended for the traversal zone between them?

  1. Assured Services SIP over TCP with TLS Correct answer.
  2. UDP 5060 with no encryption
  3. H.323 RAS over UDP 1719
  4. SCCP over TCP 2000

Explanation

The traversal zone between Expressway-E and Expressway-C uses Assured Services SIP over TCP, normally with TLS, because it is designed to survive NAT and firewall traversal reliably. Plain UDP SIP and legacy H.323 or SCCP are not used for this traversal link.

Question 45Collaboration Applications and Services

Which Cisco collaboration deployment model places all call-processing and application services in a Cisco-hosted cloud while the enterprise retains its own dial plan and endpoints?

  1. Cisco Webex Meetings Server on-premises
  2. Cisco Intercompany Media Engine
  3. Cisco Hosted Collaboration Solution Correct answer.
  4. Cisco Unified Communications Manager Session Management Edition

Explanation

Cisco Hosted Collaboration Solution is the partner- or Cisco-operated multitenant cloud offer where call processing and applications are hosted while each enterprise keeps its own dial plan and endpoints. The other options are on-premises or peering products rather than a hosted deployment model.

Question 46Collaboration Applications and Services

In a Cisco Unified Contact Center Express deployment, which component performs the actual routing of calls to agents and holds the queued callers?

  1. Cisco Finesse
  2. Cisco Unified Contact Center Express Engine Correct answer.
  3. Cisco Unified Communications Manager
  4. Cisco Unified Intelligence Center

Explanation

The Contact Center Express Engine executes the routing scripts and holds callers in queue while selecting agents. Unified Communications Manager provides call control, Unified Intelligence Center provides reporting, and Finesse provides the agent and supervisor desktop.

Question 47Collaboration Applications and Services

Which Cisco Unity Connection feature lets a caller press a key during a greeting to transfer to another extension or run a call handler action?

  1. Message notification
  2. Alternate greeting
  3. Caller input Correct answer.
  4. Greeting administrator

Explanation

Caller input lets a greeting present keypad options that route the caller to extensions, call handlers, or other actions. Greetings, notifications, and alternate greetings control what the caller hears or how messages are delivered, not keypad-driven routing.

Question 48Collaboration Applications and Services

Which Cisco Webex hybrid service keeps the enterprise directory as the source of truth and synchronizes users into Webex so that they can be provisioned consistently?

  1. Directory Connector Correct answer.
  2. Cisco Meeting Server
  3. Expressway-C
  4. Cisco TelePresence Management Suite

Explanation

Directory Connector synchronizes users and groups from an on-premises directory such as Active Directory into Webex, making the enterprise directory the authoritative source. Expressway-C is traversal and hybrid call-connect infrastructure, while the other two options are on-premises conferencing and management products.

Question 49Collaboration Applications and Services

An administrator wants Cisco Unified Communications Manager to send call detail records to an external billing server. Which two elements must be configured to accomplish this? (Choose the best answer.)

  1. Configure AXL access for the billing server and enable trace logging
  2. Enable CAR and set the billing server as a reporting node
  3. Enable SNMP traps and point them at the billing server
  4. Enable CDR and configure a billing server with the appropriate CDR Management settings Correct answer.

Explanation

CDR delivery requires the CDR service to be enabled and a billing application server to be defined under CDR Management with the correct protocol and directory settings. SNMP, AXL, and CAR serve other purposes and do not deliver CDR files.

Question 50Collaboration Applications and Services

A user reports that Cisco Jabber on a mobile device registers over the corporate Wi-Fi but cannot place calls when roaming on cellular data. Which Expressway-based service is required to support this?
