Question 1Campus Access Architecture and Design

In an Aruba campus design, which role does the Mobility Conductor (formerly Mobility Master) perform in a large hierarchical deployment?

  1. It terminates CAPWAP tunnels from every access point directly.
  2. It acts as the default gateway for all wireless client subnets.
  3. It forwards all client data traffic between VLANs at wire speed.
  4. It centrally manages configuration and licensing for multiple Mobility Controllers. Correct answer.

Explanation

The Mobility Conductor provides centralized configuration, licensing, and management for one or more managed Mobility Controllers in a hierarchical architecture. Data forwarding and client gateways remain on the managed controllers or gateways. This separation of control plane management from data plane forwarding is the core of the hierarchical design.

Question 2Campus Access Architecture and Design

Which Aruba architecture places the gateway function for wireless clients in the data center while access points remain at the branch?

  1. Controller-less instant access point cluster
  2. Standalone controller deployment
  3. Distributed branch gateway deployment
  4. Controller-managed centralized overlay Correct answer.

Explanation

In a centralized overlay design, APs tunnel client traffic to a gateway or controller in a central site, where the client gateway function is performed. This centralizes policy and simplifies branch operations. Distributed designs instead keep the gateway at the branch.

Question 3Campus Access Architecture and Design

A designer needs wireless client traffic to be bridged locally at each branch while still being centrally managed. Which Aruba design model best fits this requirement?

  1. Distributed branch gateway with local client gateways Correct answer.
  2. Controller-less Instant AP deployment with no central management
  3. Centralized overlay with all client traffic tunneled to the data center
  4. Standalone controller at each branch with no shared management

Explanation

A distributed branch gateway model keeps client gateway and forwarding functions at the branch while management stays centralized through the Conductor. This provides local breakout with consistent central policy. Centralized overlay would backhaul traffic unnecessarily.

Question 4Campus Access Architecture and Design

What is the primary purpose of a Mobility Controller in an Aruba campus network?

  1. To provide Layer 2 switching between access layer closets
  2. To provide PoE power to access points over copper cabling
  3. To terminate AP tunnels and enforce client policy and forwarding Correct answer.
  4. To act as the DHCP server for all wired employee subnets

Explanation

A Mobility Controller terminates CAPWAP tunnels from APs and enforces client policy, roaming, and forwarding decisions. PoE and Layer 2 switching are functions of the access switches. DHCP is typically provided by separate infrastructure.

Question 5Campus Access Architecture and Design

Which Aruba feature allows an access point to forward client traffic locally while keeping management and policy centralized?

  1. Tunneled node with no local forwarding
  2. Dynamic segmentation at the core switch
  3. Spanning tree root guard on the uplink
  4. Local bridging on the AP with centralized control Correct answer.

Explanation

Local bridging lets the AP forward client traffic onto the local VLAN while the controller or gateway retains management and policy control. This reduces backhaul for branch and remote sites. Tunneled forwarding sends all client traffic to the gateway instead.

Question 6Campus Access Architecture and Design

In Aruba Central-managed campus designs, what is the function of the Aruba Gateways in the architecture?

  1. They serve as the DNS resolver for guest clients only.
  2. They provide the wireless radio coverage for client devices.
  3. They replace the need for any access layer switching.
  4. They perform client gateway, tunneling, and policy enforcement functions. Correct answer.

Explanation

Aruba Gateways provide client gateway, tunneling, and policy enforcement functions in Central-managed deployments. APs provide radio coverage, and access switches provide wired connectivity. Gateways are not a substitute for access switching.

Question 7Campus Access Architecture and Design

A campus requires role-based policy that follows users across wired and wireless access. Which Aruba capability is designed to deliver this?

  1. MAC authentication with no role mapping
  2. Static VLAN assignment per switch port only
  3. Dynamic segmentation with role-based access control Correct answer.
  4. Spanning tree topology changes

Explanation

Dynamic segmentation applies role-based policies consistently across wired and wireless users regardless of where they connect. It uses user roles rather than static port VLANs. Static VLANs and plain MAC authentication do not provide consistent role-based policy across media.

Question 8Campus Access Architecture and Design

Which design consideration most directly determines the number of access points needed for a given floor?

  1. The number of switch ports available in the closet
  2. The size of the DHCP scope
  3. The required client density and coverage area Correct answer.
  4. The controller's license count

Explanation

AP count is driven by both coverage (area) and capacity (client density and throughput requirements). Switch ports, licenses, and DHCP scope sizes are downstream considerations, not the primary driver of AP quantity. A proper design balances coverage and capacity.

Question 9Campus Access Architecture and Design

What is the recommended purpose of a dedicated management VLAN in an Aruba campus design?

  1. To isolate management traffic for APs, controllers, and switches Correct answer.
  2. To carry guest client traffic to the internet
  3. To carry voice traffic with QoS priority
  4. To provide PoE to access points

Explanation

A dedicated management VLAN isolates device management traffic from user data, improving security and troubleshooting. Guest and voice traffic belong on their own dedicated VLANs. PoE is a physical layer function, not a VLAN purpose.

Question 10Campus Access Architecture and Design

A designer is choosing between tunneled and local forwarding for a branch with latency-sensitive applications and limited WAN bandwidth. Which choice is most appropriate?

  1. Route all client traffic through the Mobility Conductor
  2. Use local forwarding at the branch to avoid WAN backhaul Correct answer.
  3. Disable encryption to reduce latency
  4. Tunnel all traffic to the data center to simplify policy

Explanation

Local forwarding keeps client traffic at the branch, avoiding WAN backhaul latency and bandwidth consumption. Central tunneling is better when all traffic must be inspected centrally. The Conductor does not forward client data.

Question 11Campus Access Architecture and Design

Which Aruba component provides centralized visibility and AI-driven insights across a campus deployment?

  1. AP radio firmware
  2. Aruba Central Correct answer.
  3. Access layer switch ASIC
  4. Mobility Controller CLI

Explanation

Aruba Central is the cloud management platform providing centralized visibility, analytics, and AI-driven insights. Switch ASICs, controller CLI, and AP firmware are operational components, not management platforms. Central aggregates telemetry across the deployment.

Question 12Campus Access Architecture and Design

What does the term 'overlay' refer to in an Aruba campus fabric design?

  1. The wireless channel plan
  2. The physical cabling between closets
  3. The PoE budget of the access switch
  4. A logical tunneling and policy layer over the physical underlay Correct answer.

Explanation

An overlay is a logical layer built on top of the physical underlay, providing tunneling and policy for clients. The underlay provides IP connectivity between nodes. Cabling, PoE, and channel plans are physical or RF considerations.

Question 13Campus Access Architecture and Design

In an Aruba campus fabric, what is the role of the fabric underlay?

  1. It enforces client role-based policy.
  2. It provides the routed IP transport between fabric nodes. Correct answer.
  3. It terminates wireless client CAPWAP tunnels.
  4. It assigns user roles based on authentication.

Explanation

The underlay provides the routed IP transport that connects fabric nodes. Policy enforcement and role assignment occur in the overlay. CAPWAP termination is a controller or gateway function, not the underlay's role.

Question 14Campus Access Architecture and Design

A campus needs to support high-density auditoriums with many concurrent video clients. Which design factor should drive the AP and radio plan?

  1. Maximizing transmit power to cover the whole auditorium from one AP
  2. Planning for client capacity and using narrower cells with more APs Correct answer.
  3. Using only 2.4 GHz channels for wider coverage
  4. Disabling 5 GHz to reduce interference

Explanation

High-density areas require capacity planning with more APs and smaller cells rather than maximum power from a single AP. Narrower cells improve spatial reuse and per-client throughput. Relying on 2.4 GHz alone worsens contention.

Question 15Campus Access Architecture and Design

Which statement best describes the function of a tunneled node in an Aruba design?

  1. It forwards all traffic from a switch port to a gateway or controller for policy enforcement. Correct answer.
  2. It provides PoE to connected APs.
  3. It bridges traffic locally between access ports.
  4. It acts as a spanning tree root for the campus.

Explanation

A tunneled node forwards traffic from a switch port over a tunnel to a gateway or controller where policy is enforced. This is used for devices that cannot authenticate themselves or require centralized inspection. Local bridging and PoE are separate functions.

Question 16Campus Access Architecture and Design

What is the primary benefit of a hierarchical Aruba design with a Mobility Conductor and multiple managed controllers?

  1. It eliminates the need for access switches.
  2. It scales management and configuration across many controllers. Correct answer.
  3. It removes the need for client authentication.
  4. It guarantees zero roaming latency.

Explanation

A hierarchical design lets a single Conductor manage configuration and licensing for many controllers, improving scalability and consistency. It does not replace access switches, remove authentication, or guarantee zero-latency roaming.

Question 17Campus Access Architecture and Design

A designer must ensure guest clients cannot reach internal corporate subnets. Which design approach is most appropriate?

  1. Place guest clients on a dedicated VLAN with restrictive policy at the gateway Correct answer.
  2. Use a single flat VLAN for all clients
  3. Allow guest clients on the voice VLAN
  4. Assign guest clients to the management VLAN

Explanation

Guest isolation is achieved with a dedicated guest VLAN and restrictive policy enforced at the gateway or controller. Placing guests on management or voice VLANs exposes sensitive resources. A flat VLAN removes all segmentation.

Question 18Campus Access Architecture and Design

Which factor most influences the choice between a centralized and a distributed gateway model for a multi-site campus?

  1. The number of PoE ports in each closet
  2. The color of the switch faceplates
  3. The traffic patterns and WAN bandwidth between sites Correct answer.
  4. The length of the patch cables

Explanation

Traffic patterns and available WAN bandwidth determine whether backhauling client traffic to a central gateway is acceptable. Distributed gateways are preferred when local breakout is needed. Physical attributes like faceplates and cable length do not drive this decision.

Question 19Campus Access Architecture and Design

What does Aruba's role-based access control use to determine a client's network privileges?

  1. The AP's transmit power setting
  2. The assigned user role derived from authentication and device context Correct answer.
  3. The client's MAC address vendor prefix only
  4. The physical switch port number only

Explanation

Role-based access control assigns a user role based on authentication and device context, then applies policy to that role. MAC vendor prefixes, static port numbers, and radio power settings are not the basis of role assignment. Roles follow users across the campus.

Question 20Campus Access Architecture and Design

A campus design includes redundant Mobility Controllers. What is the primary design goal of controller redundancy?

  1. To increase wireless transmit power
  2. To maintain client service if a controller fails Correct answer.
  3. To reduce the number of access points needed
  4. To eliminate the need for a management VLAN

Explanation

Controller redundancy ensures client service continuity if a controller fails, typically through clustering or standby configurations. It does not affect transmit power, AP count, or management VLAN requirements. High availability is a core campus design principle.

Question 21Campus Access Architecture and Design

Which Aruba design element provides consistent policy enforcement for both wired and wireless clients in a fabric?

  1. The overlay with role-based policy at fabric edge and gateway nodes Correct answer.
  2. The physical underlay routing protocol
  3. The AP channel plan
  4. The PoE budget of the access switch

Explanation

The overlay enforces role-based policy at fabric edge and gateway nodes, giving consistent treatment for wired and wireless clients. The underlay only provides transport. PoE and channel plans are unrelated to policy enforcement.

Question 22Campus Access Architecture and Design

A designer is evaluating whether to use Aruba Central or an on-premises management platform. Which requirement most strongly favors Aruba Central?

  1. A need for cloud-based centralized management and analytics across sites Correct answer.
  2. A requirement to avoid any internet connectivity for management
  3. A need for the lowest possible PoE power draw
  4. A requirement to use only Layer 2 switching

Explanation

Aruba Central is a cloud platform providing centralized management and analytics across distributed sites. Environments that prohibit internet-based management favor on-premises options. PoE draw and Layer 2 switching are unrelated to the management platform choice.

Question 23Campus Access Architecture and Design

In a campus design, why is it important to plan for client roaming boundaries such as buildings and floors?

  1. To eliminate the need for authentication
  2. To ensure RF coverage overlap supports seamless roaming between APs Correct answer.
  3. To increase the PoE budget
  4. To reduce the number of VLANs required

Explanation

Roaming boundaries require sufficient RF overlap so clients can move between APs without dropping connectivity. Proper overlap and channel planning support seamless roaming. Roaming planning does not reduce VLANs, remove authentication, or affect PoE.

Question 24Campus Access Architecture and Design

Which statement accurately describes the relationship between a Mobility Conductor and managed Mobility Controllers?

  1. The Conductor forwards all client data between controllers.
  2. The Conductor pushes configuration to controllers but does not forward client data. Correct answer.
  3. Controllers cannot operate without the Conductor forwarding their traffic.
  4. Controllers push configuration to the Conductor.

Explanation

The Conductor centrally manages and pushes configuration to managed controllers but does not sit in the client data path. Controllers continue forwarding client traffic independently. Configuration flows from Conductor to controllers, not the reverse.

Question 25Campus Access Architecture and Design

A campus has strict regulatory requirements that all wireless client traffic be inspected by a central security stack before reaching the internet. Which forwarding design best meets this requirement?

  1. Local bridging at each AP
  2. Centralized tunneling of client traffic to a gateway Correct answer.
  3. Disabling client isolation on the AP
  4. Controller-less Instant AP with local breakout

Explanation

Centralized tunneling directs client traffic through a central gateway where security inspection can occur. Local bridging and local breakout bypass the central stack. Client isolation settings do not route traffic through central inspection.

Question 26Campus Access Architecture and Design

In an Aruba campus design, what is the primary purpose of a Mobility Master (now Mobility Conductor) in a hierarchical architecture?

  1. To serve as the default gateway for all wireless client traffic
  2. To act as the DHCP server for all client VLANs
  3. To terminate VPN tunnels from remote access points
  4. To provide centralized configuration, policy, and firmware management for multiple managed controllers Correct answer.

Explanation

The Mobility Conductor centralizes control-plane functions such as configuration, policy definition, and firmware management for managed controllers, simplifying operations across large deployments. It does not forward user traffic or provide network services like DHCP or default gateway functions.

Question 27Campus Access Architecture and Design

Which Aruba technology allows a single access point to broadcast multiple SSIDs, each mapped to a different VLAN and security policy?

  1. ARM
  2. ClientMatch
  3. AirGroup
  4. Multi-zone Correct answer.

Explanation

Multi-zone enables an AP to support multiple SSIDs with distinct VLANs and policies, often used for guest or overlay networks without deploying separate APs. AirGroup handles service discovery, ClientMatch steers clients, and ARM manages radio parameters.

Question 28Campus Access Architecture and Design

When designing an Aruba campus network with redundant gateways, which redundancy model provides active-active forwarding with sub-second failover?

  1. MC-LAG with VRRP
  2. Dual-link transparent mode
  3. Primary-secondary clustering Correct answer.
  4. VRRP with preemption disabled

Explanation

Primary-secondary clustering allows both gateways to actively forward traffic while sharing state, enabling sub-second failover if one fails. VRRP is typically active-standby, transparent mode does not provide gateway redundancy, and MC-LAG is a Layer 2 multichassis link aggregation technique.

Question 29Campus Access Architecture and Design

What is the recommended maximum number of access points per Aruba Mobility Controller in a large campus design to ensure optimal performance?

  1. 64
  2. 128
  3. 256 Correct answer.
  4. 512

Explanation

Aruba recommends a maximum of 256 access points per controller for large campus deployments to balance performance and scalability. Higher numbers may be supported in specific models but can impact throughput and latency.

Question 30Campus Access Architecture and Design

In an Aruba campus fabric, which component is responsible for mapping client traffic to the correct overlay network based on policy?

  1. Fabric edge Correct answer.
  2. Fabric underlay
  3. Fabric border
  4. Fabric overlay

Explanation

The fabric edge (access switch) classifies and maps client traffic into the appropriate overlay based on role and policy. The underlay provides IP connectivity, the overlay carries tenant traffic, and the border connects the fabric to external networks.

Question 31Campus Access Architecture and Design

Which Aruba feature enables a wired client to be dynamically assigned to a role based on its MAC address or authentication credentials?

  1. Port Security
  2. 802.1X
  3. Role-Based Access Control (RBAC)
  4. Dynamic Segmentation Correct answer.

Explanation

Dynamic Segmentation uses role-based policies to assign wired and wireless clients to appropriate network segments and policies based on identity, device type, or location. RBAC is the underlying policy model, while 802.1X is an authentication method and Port Security limits MAC addresses.

Question 32Campus Access Architecture and Design

What is the primary benefit of using Aruba's AirMatch feature in a high-density campus design?

  1. It enables seamless roaming between controllers
  2. It enforces role-based access policies for IoT devices
  3. It provides centralized authentication for wireless clients
  4. It automates RF optimization by adjusting channel and power settings based on network conditions Correct answer.

Explanation

AirMatch uses cloud-based optimization to automatically adjust channel and transmit power settings, improving RF performance and reducing interference in high-density environments. Authentication, policy enforcement, and roaming are handled by other features.

Question 33Campus Access Architecture and Design

When designing a campus network for VoIP, which Aruba feature ensures voice traffic is prioritized over data traffic?

  1. QoS roles Correct answer.
  2. Band steering
  3. ClientMatch
  4. AirGroup

Explanation

QoS roles define traffic prioritization and ensure voice packets are treated with higher priority across the network. AirGroup manages service discovery, ClientMatch steers clients, and band steering pushes clients to 5 GHz.

Question 34Campus Access Architecture and Design

In an Aruba campus design, what is the recommended approach for connecting access points to the network?

  1. To access switches with PoE+ and redundant uplinks Correct answer.
  2. Directly to the core switches for lowest latency
  3. Using wireless mesh for all APs
  4. To a dedicated AP controller in each building

Explanation

Access points should connect to access switches that provide PoE+ power and redundant uplinks to ensure power and network resilience. Connecting directly to core switches is not scalable, dedicated per-building controllers add complexity, and wireless mesh is typically for special cases.

Question 35Campus Access Architecture and Design

Which Aruba design principle helps prevent broadcast storms in a large campus Layer 2 network?

  1. Link Aggregation Control Protocol (LACP)
  2. Dynamic Host Configuration Protocol (DHCP) snooping
  3. Spanning Tree Protocol (STP) with root guard
  4. VLAN segmentation and storm control Correct answer.

Explanation

VLAN segmentation limits broadcast domains, and storm control suppresses excessive broadcast, multicast, or unknown unicast traffic. STP prevents loops, DHCP snooping protects against rogue servers, and LACP aggregates links.

Question 36Campus Access Architecture and Design

What is the role of the Aruba Fabric Composer in a campus fabric deployment?

  1. It acts as a wireless controller for APs
  2. It monitors RF interference and adjusts channels
  3. It provides a graphical interface to design and deploy fabric underlay and overlay networks Correct answer.
  4. It serves as a RADIUS server for authentication

Explanation

Aruba Fabric Composer is a management tool that simplifies the design and deployment of fabric underlay and overlay networks through a graphical interface. It does not provide wireless control, authentication, or RF management.

Question 37Campus Access Architecture and Design

When designing a campus network with Aruba Central, which feature provides AI-powered insights and recommendations for network optimization?

  1. NetInsight Correct answer.
  2. ClearPass Policy Manager
  3. AirGroup
  4. ClientMatch

Explanation

NetInsight is the AIOps feature within Aruba Central that uses machine learning to provide insights and recommendations for improving network performance. ClientMatch steers clients, AirGroup manages service discovery, and ClearPass provides policy management.

Question 38Campus Access Architecture and Design

In a campus design with Aruba Gateways, what is the purpose of the gateway's overlay tunnels?

  1. To synchronize configuration between gateways
  2. To provide redundant power to access points
  3. To carry client traffic between the gateway and access points or switches Correct answer.
  4. To enable wireless mesh connectivity

Explanation

Overlay tunnels encapsulate and carry client traffic from access points or fabric switches to the gateway for centralized policy enforcement and forwarding. They do not provide power, configuration sync, or mesh connectivity.

Question 39Campus Access Architecture and Design

Which Aruba solution provides a unified policy framework for wired and wireless access across the campus?

  1. AirWave
  2. Fabric Composer
  3. NetEdit
  4. ClearPass Policy Manager Correct answer.

Explanation

ClearPass Policy Manager delivers a unified policy engine that enforces role-based access control for both wired and wireless clients, integrating with network devices. AirWave is for monitoring, NetEdit for configuration management, and Fabric Composer for fabric orchestration.

Question 40Campus Access Architecture and Design

What is the recommended design practice for placement of Aruba Gateways in a multi-building campus to minimize latency for client traffic?

  1. Place gateways in each access closet
  2. Place gateways in a centralized data center
  3. Place gateways at the core layer only
  4. Place gateways at the distribution layer of each building Correct answer.

Explanation

Placing gateways at the distribution layer of each building reduces latency by keeping traffic local and avoiding backhaul to a central site. Centralized data center placement adds latency, core-only placement may not scale, and access closet placement is not practical.

Question 41Campus Access Switching and Routing Configuration

On an ArubaOS-CX switch, which command creates a VLAN and enters its configuration context?

  1. vlan 20 Correct answer.
  2. create vlan 20
  3. vlan database
  4. interface vlan 20

Explanation

In ArubaOS-CX, the global configuration command 'vlan <id>' creates the VLAN if it does not exist and immediately places the CLI into that VLAN's context. From there you can name the VLAN or assign ports. The 'interface vlan' form is used for the Layer 3 SVI, not for creating the VLAN itself.

Question 42Campus Access Switching and Routing Configuration

Which statement describes the default behavior of an ArubaOS-CX access port that has been assigned to a single VLAN?

  1. It forwards untagged frames in that VLAN and drops tagged frames. Correct answer.
  2. It tags all frames with an 802.1Q header.
  3. It forwards only frames matching the native VLAN configured globally.
  4. It forwards both tagged and untagged frames in that VLAN.

Explanation

An access port belongs to exactly one VLAN and sends and receives untagged traffic for that VLAN. Tagged frames arriving on an access port are not expected and are dropped. Trunk ports, by contrast, carry multiple VLANs using 802.1Q tags.

Question 43Campus Access Switching and Routing Configuration

A trunk link between two ArubaOS-CX switches must carry VLANs 10, 20, and 30 tagged, and must not carry any other VLAN. Which configuration accomplishes this?

  1. vlan 10,20,30 followed by no shutdown on the interface
  2. vlan trunk allowed 10,20,30 applied to the interface Correct answer.
  3. interface vlan 10,20,30 applied globally
  4. switchport trunk native vlan 10 applied to the interface

Explanation

On ArubaOS-CX, the allowed VLAN list for a trunk port is set with 'vlan trunk allowed <list>'. This restricts the trunk to exactly the listed VLANs while tagging them. The native VLAN command only designates one untagged VLAN and does not define the tagged set.

Question 44Campus Access Switching and Routing Configuration

What is the purpose of the native VLAN on an 802.1Q trunk port?

  1. It encrypts all traffic traversing the trunk.
  2. It is reserved for management access only.
  3. It is the highest-numbered VLAN allowed on the trunk.
  4. It carries untagged frames on the trunk. Correct answer.

Explanation

The native VLAN is the VLAN whose frames are transmitted untagged across a trunk link. Frames for all other allowed VLANs carry an 802.1Q tag. Both ends of the trunk should agree on the native VLAN to avoid misforwarding.

Question 45Campus Access Switching and Routing Configuration

Which command displays the spanning tree state and role of each port on an ArubaOS-CX switch?

  1. show lldp neighbors
  2. show stp brief
  3. show running-config
  4. show spanning-tree Correct answer.

Explanation

'show spanning-tree' on ArubaOS-CX reports the spanning tree mode, root bridge information, and per-port role and state. It is the primary verification command for STP operation. The other commands show configuration, LLDP, or unrelated data.

Question 46Campus Access Switching and Routing Configuration

A network engineer wants an ArubaOS-CX access switch to participate in RSTP with rapid convergence and a defined root preference. Which configuration achieves this?

  1. spanning-tree disable on all access ports
  2. loop-protect enabled on the uplink
  3. spanning-tree mode rapid-pvst with a priority set on the switch Correct answer.
  4. spanning-tree mode mstp with default parameters

Explanation

Setting 'spanning-tree mode rapid-pvst' enables rapid per-VLAN spanning tree, and configuring a lower bridge priority influences root election. Together they provide fast convergence and predictable root placement. Disabling STP or relying on defaults does not meet the requirement.

Question 47Campus Access Switching and Routing Configuration

Which ArubaOS-CX feature aggregates multiple physical links into a single logical link to increase bandwidth and redundancy?

  1. VRRP
  2. LAG Correct answer.
  3. MSTP
  4. LLDP

Explanation

A Link Aggregation Group (LAG) bundles multiple physical interfaces into one logical interface, providing increased throughput and link redundancy. It is defined by the IEEE 802.3ad/802.1AX standard. MSTP, VRRP, and LLDP serve different purposes.

Question 48Campus Access Switching and Routing Configuration

Which command creates a static LAG on an ArubaOS-CX switch and assigns interfaces to it?

  1. port-channel 10 followed by channel members
  2. bond 10 followed by slave interfaces
  3. link-aggregation 10 followed by port members
  4. interface lag 10 followed by interface members Correct answer.

Explanation

On ArubaOS-CX, 'interface lag <id>' creates the logical LAG interface, and member physical interfaces are added within it. This is the native LAG configuration model for the platform. The other command forms belong to different vendors or are not valid.

Question 49Campus Access Switching and Routing Configuration

What is the primary function of a switched virtual interface (SVI) on a Layer 3 ArubaOS-CX switch?

  1. To aggregate physical links
  2. To provide a routed interface for a VLAN Correct answer.
  3. To tag frames on trunk links
  4. To discover neighboring devices

Explanation

An SVI is a logical Layer 3 interface associated with a VLAN, allowing the switch to route traffic to and from that VLAN. It is created with 'interface vlan <id>' and assigned an IP address. Tagging, link aggregation, and discovery are handled by other features.

Question 50Campus Access Switching and Routing Configuration

Which command assigns an IPv4 address to an SVI for VLAN 50 on an ArubaOS-CX switch?

  1. interface vlan 50 ip 10.0.50.1 mask 255.255.255.0 issued globally
  2. ip address 10.0.50.1/24 issued inside interface vlan 50 Correct answer.
  3. ip address 10.0.50.1 255.255.255.0 issued globally
  4. vlan 50 ip 10.0.50.1/24 issued globally

Explanation

The IP address is applied inside the SVI context using CIDR notation, for example 'interface vlan 50' followed by 'ip address 10.0.50.1/24'. ArubaOS-CX uses prefix-length notation for interface addressing. The other forms are not valid command structure.
