Question 1Implementing and Managing Cisco MDS Switches

On a Cisco MDS 9000 switch, which command displays the WWN, operational state, and VSAN membership of every locally attached N-port?

  1. show interface fc1/1 brief
  2. show vsan membership
  3. show fcns database
  4. show flogi database Correct answer.

Explanation

The FLOGI database lists each fabric login received on local Fx ports, showing the logged-in N-port WWN, the interface it was learned on, and the VSAN it belongs to. The name server database shows devices registered fabric-wide, not just locally attached ones.

Question 2Implementing and Managing Cisco MDS Switches

A SAN administrator wants a new VSAN to be able to use F-port trunking toward an ISL. Which port attributes must be configured on the participating interfaces?

  1. The interfaces must be configured as Fx ports with the trunking VSAN as their only membership.
  2. The interfaces must be configured as NP ports and enabled for beaconing.
  3. The interfaces must be configured as TE ports within the trunking VSAN. Correct answer.
  4. The interfaces must be configured as SD ports and bound to the VSAN.

Explanation

Trunking between switches requires E ports that are allowed to carry multiple VSANs, which makes them TE ports. A TE port carries tagged frames for every VSAN permitted on the trunk.

Question 3Implementing and Managing Cisco MDS Switches

Which statement describes the effect of the zone default-zone permit vsan command on a VSAN?

  1. Zones in that VSAN are automatically merged with the default zone during a fabric merge.
  2. Traffic in the VSAN is denied unless an explicit zone set is activated.
  3. Devices that are not explicitly zoned are allowed to communicate within that VSAN. Correct answer.
  4. The default zone is renamed and all members are moved into a new zone set.

Explanation

By default the default zone is set to deny, so unzoned devices cannot communicate. Enabling default-zone permit allows members that are not part of any active zone to talk to each other in that VSAN.

Question 4Implementing and Managing Cisco MDS Switches

An administrator needs to change the VSAN membership of interface fc1/10 from VSAN 10 to VSAN 20. What must be done first?

  1. Remove the interface from the active zone set of VSAN 10.
  2. Convert the port to an SD port.
  3. Delete the FLOGI entry for the attached host.
  4. Shut down the interface before changing its VSAN assignment. Correct answer.

Explanation

A port's VSAN assignment cannot be changed while the interface is up; the interface must be shut down first, reassigned, and then brought back up. This prevents an unclean transition of the port between fabrics.

Question 5Implementing and Managing Cisco MDS Switches

Which protocol does a Cisco MDS switch use to distribute zone information to other switches in the same VSAN?

  1. FSPF link state advertisements
  2. Exchange Link Parameters during port initialization
  3. Cisco Fabric Services over the management network Correct answer.
  4. FC-GS-3 name server updates

Explanation

Zone data is distributed by Cisco Fabric Services, which replicates the zone database to peer switches over the management or in-band network. FSPF handles routing, not zone distribution.

Question 6Implementing and Managing Cisco MDS Switches

A host is zoned with two storage ports in a single zone, and the administrator wants the host to see only one target at a time for multipath failover testing. Which zoning approach satisfies this requirement without changing physical cabling?

  1. Create two zones, each pairing the host with one target, and activate only the desired zone set. Correct answer.
  2. Create an IVR zone between the two targets.
  3. Create a single zone containing the host and both targets and enable default-zone permit.
  4. Create a zone set containing both zones so the host sees both targets simultaneously.

Explanation

Single-initiator, single-target zones isolate each path, so activating a zone set that contains only one pairing limits the host to that target. This is the standard method for controlled path visibility without recabling.

Question 7Implementing and Managing Cisco MDS Switches

Which command creates a zone named web_prod in VSAN 5 and adds pWWN 20:00:00:00:c9:aa:bb:cc as a member?

  1. fcalias name web_prod vsan 5 pwwn 20:00:00:00:c9:aa:bb:cc
  2. zone name web_prod vsan 5 pwwn 20:00:00:00:c9:aa:bb:cc Correct answer.
  3. zoneset name web_prod vsan 5 pwwn 20:00:00:00:c9:aa:bb:cc
  4. zone create web_prod vsan 5 member 20:00:00:00:c9:aa:bb:cc

Explanation

In VSAN configuration mode the zone name command creates the zone and accepts pwwn, fcalias, fcid, or interface members. The member keyword is not used in this syntax.

Question 8Implementing and Managing Cisco MDS Switches

After a fabric merge, two switches in VSAN 3 have conflicting active zone sets. What is the result of the merge for that VSAN?

  1. The larger zone set overwrites the smaller one automatically.
  2. The zone sets are merged by taking the union of all members.
  3. The switch with the lower principal switch priority wins and its zone set is kept.
  4. The VSAN is isolated and its links are kept down until the databases match. Correct answer.

Explanation

When active zone sets differ during a merge, the merge fails for that VSAN and the ISL is isolated so the two fabrics stay separate. The VSAN remains non-operational on the link until the databases are reconciled.

Question 9Implementing and Managing Cisco MDS Switches

Which feature allows a set of N-ports to log in to the fabric through a single domain ID on the core switch?

  1. PortChannel
  2. IVR
  3. NPV Correct answer.
  4. Smart Zoning

Explanation

N-port virtualization lets an edge switch proxy its hosts to the core so they share the core switch's domain, reducing domain ID consumption. The edge device runs in NPV mode and does not take its own domain.

Question 10Implementing and Managing Cisco MDS Switches

A SAN administrator must verify that the active zone set in VSAN 10 contains a zone named db_zone. Which command shows the active zone set contents?

  1. show zone vsan 10
  2. show zoneset active vsan 10 Correct answer.
  3. show running-config zone vsan 10
  4. show zoneset pending vsan 10

Explanation

The show zoneset active command displays the currently activated zone set and its zones and members for the specified VSAN. The pending variant shows changes that have not been committed.

Question 11Implementing and Managing Cisco MDS Switches

An administrator wants to prevent a specific host port from being able to log in to the fabric at all. Which mechanism is designed for this?

  1. A zone set that omits the host
  2. Port security with a configured WWN allow list Correct answer.
  3. An fcalias containing the host WWN
  4. Default-zone deny

Explanation

Port security binds an interface to specific WWNs so any other device attempting FLOGI on that port is rejected. Zoning controls communication between logged-in devices but does not block login.

Question 12Implementing and Managing Cisco MDS Switches

Which command enables the fabric binding feature on a switch so that only listed switches may join the fabric?

  1. fabric-binding activate vsan 1 Correct answer.
  2. fabric-binding enable
  3. fabric-binding database vsan 1
  4. port-security enable

Explanation

Fabric binding is configured per VSAN with a member list and then activated, which enforces that only listed switch WWNs participate in the fabric. Activation is what turns enforcement on.

Question 13Implementing and Managing Cisco MDS Switches

An administrator issues the interface fc1/1 command and then switchport mode F. Which port type results?

  1. The port becomes an E-port and forms an ISL.
  2. The port becomes an F-port and accepts a single host login. Correct answer.
  3. The port becomes a TE-port and trunks all allowed VSANs.
  4. The port becomes an SD-port and detects loop devices.

Explanation

Forcing switchport mode F configures the interface as a fabric port that accepts one N-port login, typically a host or a target. The mode is fixed rather than negotiated.

Question 14Implementing and Managing Cisco MDS Switches

A host is connected to fc1/5 and the administrator sees the port in an initializing state with no FLOGI. Which two conditions should be checked first?

  1. The trunking allowed VSAN list and the principal switch priority
  2. The zone set activation time and the FSPF cost
  3. The port VSAN assignment and the admin state of the interface Correct answer.
  4. The IVR topology and the local domain ID

Explanation

A port that cannot complete FLOGI is usually shut down administratively or assigned to a VSAN that does not match the attached device's expectations. Verifying admin state and VSAN membership is the first diagnostic step.

Question 15Implementing and Managing Cisco MDS Switches

Which command is used to create a PortChannel of two ISLs toward a peer switch?

  1. interface san-port-channel 1 and member fc1/1,fc1/2
  2. port-channel create 1 members fc1/1,fc1/2
  3. interface port-channel 1 followed by channel-group 1 on each member interface Correct answer.
  4. interface fc1/1 followed by port-channel 1 force

Explanation

On the MDS platform a PortChannel is created as a port-channel interface, and each physical member is added with the channel-group command in interface configuration mode. The peer must be configured symmetrically.

Question 16Implementing and Managing Cisco MDS Switches

Which statement about FSPF is correct on a Cisco MDS fabric?

  1. FSPF computes least-cost paths between domains using link cost derived from bandwidth. Correct answer.
  2. FSPF load-balances frames across all ISLs regardless of cost.
  3. FSPF assigns domain IDs during principal switch election.
  4. FSPF distributes zone information to all switches in a VSAN.

Explanation

FSPF is the Fibre Channel routing protocol that builds a topology database per VSAN and selects least-cost paths based on link cost, which by default reflects link bandwidth. Domain assignment is handled separately by the principal switch.

Question 17Implementing and Managing Cisco MDS Switches

An administrator needs to permit a host in VSAN 10 to access a target in VSAN 20 without merging the VSANs. Which technology applies?

  1. NPV on the edge switch
  2. Fabric binding between the two VSANs
  3. IVR with an IVR zone set Correct answer.
  4. Inter-VSAN trunking with TE ports

Explanation

Inter-VSAN Routing lets devices in different VSANs communicate through defined IVR zones and an IVR zone set while keeping the VSANs logically separate. Trunking carries VSANs over a link but does not merge or route between them.

Question 18Implementing and Managing Cisco MDS Switches

Which command displays the domain ID, principal switch status, and running configuration for the local switch in VSAN 1?

  1. show fcdomain domain-list vsan 1 Correct answer.
  2. show vsan 1
  3. show fspf vsan 1
  4. show flogi database vsan 1

Explanation

The fcdomain domain-list output shows each domain in the VSAN along with the principal switch indication and local running configuration. It is the standard way to confirm domain allocation.

Question 19Implementing and Managing Cisco MDS Switches

A zone set is modified on one switch but not activated. What is the state of that zone set?

  1. It replaces the active zone set automatically at the next merge.
  2. It is immediately enforced across the fabric without activation.
  3. It is discarded when the session ends unless saved to startup-config.
  4. It exists in the full database as a pending change until a commit or activation occurs. Correct answer.

Explanation

Zone edits are held as pending changes in the full zone database until they are committed or a zone set is activated. Only the active zone set is enforced by the fabric.

Question 20Implementing and Managing Cisco MDS Switches

Which command saves the running configuration so that VSAN and zone changes survive a reload?

  1. copy running-config startup-config Correct answer.
  2. copy startup-config running-config
  3. reload module 1
  4. write erase

Explanation

Saving the running configuration to startup-config persists VSAN, zone, and interface changes across a reload. Without this step the device returns to the previously saved configuration.

Question 21Implementing and Managing Cisco MDS Switches

An administrator wants a zone member defined by interface rather than by pWWN so that replacing a host HBA keeps the zone valid. Which member type should be used?

  1. fcalias host1
  2. 20:00:00:00:c9:aa:bb:cc
  3. device-alias host1
  4. fc1/5 Correct answer.

Explanation

Interface-based zoning (also called port zoning) uses the physical port, so a failed HBA can be swapped without editing the zone. WWN-based members would require updating the zone when the HBA changes.

Question 22Implementing and Managing Cisco MDS Switches

Which statement describes the behavior of a TE port when the trunking VSAN list is changed?

  1. The change requires a fabric reconfiguration and domain reset.
  2. Only VSANs in the allowed list are carried over the ISL. Correct answer.
  3. All VSANs are always carried once the port becomes TE.
  4. The port reverts to E mode and carries only VSAN 1.

Explanation

A TE port carries traffic only for VSANs permitted by the trunking allowed list, which can be limited per interface. VSANs outside the list are not forwarded across that ISL.

Question 23Implementing and Managing Cisco MDS Switches

Which feature must be enabled on a switch before device aliases can be created and distributed to the fabric?

  1. fcalias distribute
  2. device-alias distribute Correct answer.
  3. fcdomain restart disruptive
  4. zone distribute full

Explanation

Device alias distribution must be enabled so that aliases created locally are propagated to other switches using Cisco Fabric Services. Until distribution is enabled, aliases remain local to the switch.

Question 24Implementing and Managing Cisco MDS Switches

A switch shows a port in the isolated state after an ISL was connected. Which condition most likely explains this?

  1. The port is configured as an F-port and awaiting a host login.
  2. The VSAN is not operational on the link because of a zone or VSAN parameter mismatch. Correct answer.
  3. The port is administratively shut down.
  4. The port is a member of a PortChannel that is up.

Explanation

An isolated E or TE port means the link initialized but the VSAN could not become operational, often due to zone database or VSAN parameter mismatches between peers. Administratively down ports show as disabled rather than isolated.

Question 25Implementing and Managing Cisco MDS Switches

Which command displays the VSANs configured on a switch along with their states and interface membership counts?

  1. show vsan Correct answer.
  2. show interface brief
  3. show zoneset active
  4. show vsan membership

Explanation

The show vsan command lists each configured VSAN with attributes such as state and the number of member interfaces. It is the quickest way to confirm VSAN creation and status.

Question 26Implementing and Managing Cisco MDS Switches

In Cisco MDS NX-OS, which command sequence creates a device alias named web_hba with pWWN 20:01:00:25:b5:00:aa:01 and commits it to the fabric?

  1. device-alias create web_hba pwwn 20:01:00:25:b5:00:aa:01, then copy running-config startup-config
  2. fcalias name web_hba pwwn 20:01:00:25:b5:00:aa:01, then fcalias commit
  3. device-alias database, then device-alias name web_hba pwwn 20:01:00:25:b5:00:aa:01, then device-alias commit Correct answer.
  4. device-alias config web_hba 20:01:00:25:b5:00:aa:01, then device-alias distribute

Explanation

Device aliases are edited inside the device-alias database configuration submode, where each entry is defined with the device-alias name <name> pwwn <pwwn> form. Because the device-alias feature uses a pending database, the change is only distributed to the fabric after device-alias commit is issued.

Question 27Implementing and Managing Cisco MDS Switches

What is the default port mode of an unconfigured Fibre Channel port on a Cisco MDS switch when an ISL-capable peer is attached?

  1. E port
  2. TE port
  3. F port
  4. auto Correct answer.

Explanation

By default, MDS Fibre Channel interfaces run in auto mode, meaning the switch negotiates the operational port type based on what the attached device supports. If the peer performs ELP, the port becomes an E port; if a host performs FLOGI, it becomes an F port.

Question 28Implementing and Managing Cisco MDS Switches

A SAN administrator wants ISLs between two MDS 9000 switches to carry VSANs 10, 20, and 30 over a single physical link. Which configuration enables this?

  1. switchport mode F on each ISL and vsan 10,20,30 applied to the interfaces
  2. switchport trunk allowed vsan 10,20,30 on each ISL configured with switchport mode TE Correct answer.
  3. switchport trunk allowed vsan all on interfaces left in auto mode
  4. switchport mode E on each ISL with no trunking configuration

Explanation

Trunking is enabled by configuring the interface as a TE port and then restricting the allowed VSAN list with switchport trunk allowed vsan. A plain E port carries only a single VSAN, which is the VSAN assigned to the interface.

Question 29Implementing and Managing Cisco MDS Switches

Which command displays the local switch's worldwide name, domain ID, and principal switch priority for VSAN 1?

  1. show interface fc1/1
  2. show fspf vsan 1
  3. show vsan 1
  4. show fcdomain vsan 1 Correct answer.

Explanation

show fcdomain reports domain manager information for the VSAN, including the local switch WWN, the assigned domain ID, and principal switch priority and role. This is the standard way to verify domain assignment and principal switch status.

Question 30Implementing and Managing Cisco MDS Switches

An administrator needs a port to come up as an E port immediately without negotiating with the peer. Which configuration accomplishes this?

  1. switchport mode NP
  2. switchport mode E Correct answer.
  3. switchport mode auto
  4. switchport mode F

Explanation

Configuring switchport mode E forces the interface to operate as an expansion port and skip the automatic negotiation used in auto mode. The peer must also be configured to accept an E port for the link to come up.

Question 31Implementing and Managing Cisco MDS Switches

After a new ISL is connected, a port stays in the isolated state. Which condition best explains this?

  1. The peer port is configured as an F port instead of an E port.
  2. The port is shut down administratively.
  3. The VSAN allowed list on the trunk does not match the peer. Correct answer.
  4. The port has exceeded its receive buffer credit limit.

Explanation

An isolated state on an ISL typically indicates a configuration mismatch with the peer, such as differing trunking allowed VSAN lists or incompatible parameters. The link is physically up but the fabric parameters do not agree, so the port is isolated from the fabric.

Question 32Implementing and Managing Cisco MDS Switches

Which command shows all configured VSANs with their states and the number of interfaces in each?

  1. show run vsan
  2. show interface brief
  3. show vsan Correct answer.
  4. show vsan membership

Explanation

show vsan lists each configured VSAN along with its operational state and the count of ports and the membership summary. It is the quickest way to see which VSANs exist and whether they are active.

Question 33Implementing and Managing Cisco MDS Switches

Which command creates VSAN 25 with the name backup_san?

  1. vsan 25 name backup_san
  2. vsan create 25 backup_san
  3. vsan 25, then name backup_san
  4. vsan database, then vsan 25 name backup_san Correct answer.

Explanation

VSANs must be created inside the vsan database configuration submode using the vsan <id> name <name> syntax. Creating the VSAN is separate from assigning interfaces to it.

Question 34Implementing and Managing Cisco MDS Switches

An administrator wants to save the running configuration so that VSAN and zone changes persist after a reload. Which command is correct?

  1. checkpoint create
  2. copy running-config startup-config Correct answer.
  3. write erase
  4. copy startup-config running-config

Explanation

The startup configuration is what the switch loads at boot, so running changes must be copied to it with copy running-config startup-config. Zone set activation and VSAN creation only persist once the configuration is saved.

Question 35Implementing and Managing Cisco MDS Switches

Which statement describes the effect of changing the allowed VSAN list on an operational TE port?

  1. The change is rejected while the port is carrying traffic.
  2. Traffic for VSANs still in the allowed list continues without disruption while removed VSANs are pruned. Correct answer.
  3. The port is brought down and renegotiated, so traffic for removed VSANs is disrupted.
  4. The change takes effect only after the peer switch is reloaded.

Explanation

On a TE port, the allowed VSAN list can be modified while the trunk is operational. VSANs that remain allowed continue to pass traffic, and only the removed VSANs have their traffic pruned, so the change is largely non-disruptive.

Question 36Implementing and Managing Cisco MDS Switches

Which feature must be enabled before device alias entries can be created and distributed to other switches in the fabric?

  1. fcalias distribute
  2. device-alias feature Correct answer.
  3. fcdomain restart
  4. zone default-zone permit

Explanation

Device aliases are a licensed, feature-based capability that must be turned on with the device-alias feature command before the database can be edited or committed. Once enabled, entries are distributed fabric-wide on commit.

Question 37Implementing and Managing Cisco MDS Switches

Which command verifies the operational state of a PortChannel used as an ISL trunk?

  1. show port-channel database
  2. show trunk protocol
  3. show interface port-channel 1 brief Correct answer.
  4. show fspf internal route

Explanation

show interface port-channel <n> brief reports the PortChannel's operational state, member ports, and VSAN. It confirms whether the bundled ISL is up and forwarding.

Question 38Implementing and Managing Cisco MDS Switches

An administrator wants to prevent a specific host port from logging in to the fabric at all, without relying on zoning. Which mechanism is appropriate?

  1. Fabric binding with the host's pWWN
  2. Device alias with a reserved name
  3. Port security with an auto-learned WWN entry Correct answer.
  4. A zone containing the host port as its only member

Explanation

Port security can restrict which WWNs are permitted to log in on a given port; an unauthorized device is denied FLOGI and cannot join the fabric. Zoning controls communication after login, not login itself.

Question 39Implementing and Managing Cisco MDS Switches

Which command enables fabric binding on a switch for VSAN 10?

  1. fabric-binding distribute vsan 10
  2. fabric-binding database vsan 10, then fabric-binding enable Correct answer.
  3. fabric-binding enable
  4. fabric-binding activate vsan 10

Explanation

Fabric binding requires populating the binding database for the VSAN and then enabling the feature. The switch only permits the listed switch WWNs to participate in the fabric once enabled.

Question 40Implementing and Managing Cisco MDS Switches

Which command verifies that the active zone set in VSAN 10 contains a zone named db_zone and lists its members?

  1. show zoneset active vsan 10 Correct answer.
  2. show zone db_zone vsan 10
  3. show running-config zone vsan 10
  4. show zoneset vsan 10

Explanation

show zoneset active displays the currently activated zone set and the zones and members it contains, which is what confirms db_zone is in the active set. The other commands show configuration or saved zone sets rather than the active content.

Question 41Implementing and Managing Cisco MDS Switches

A zone set is edited on one switch but never activated. What is its state in the fabric?

  1. It is automatically activated when the switch reloads.
  2. It is rejected and removed by the peer switches.
  3. It is stored as a configured but inactive zone set and does not enforce zoning. Correct answer.
  4. It is the active zone set and takes effect immediately.

Explanation

Zone set changes are only enforced when the zone set is activated with zoneset activate. Until then, the modified zone set exists in configuration but the previously active zone set continues to govern traffic.

Question 42Implementing and Managing Cisco MDS Switches

Which statement about FSPF on a Cisco MDS fabric is correct?

  1. FSPF is a distance-vector protocol that uses hop count as its metric.
  2. FSPF runs only on F ports between nodes and targets.
  3. FSPF is a link-state protocol that computes shortest paths using link cost. Correct answer.
  4. FSPF requires a separate routing instance per zone.

Explanation

FSPF is a link-state routing protocol that floods link state information within a VSAN and computes shortest paths based on link cost. It runs on E ports between switches, not on node-facing F ports.

Question 43Implementing and Managing Cisco MDS Switches

An administrator needs to merge two VSANs' device access without merging the VSANs themselves. Which technology is designed for this?

  1. Fabric binding
  2. IVR Correct answer.
  3. Trunking
  4. PortChannel

Explanation

Inter-VSAN Routing (IVR) allows devices in separate VSANs to communicate while keeping the VSANs isolated from each other. It uses a transit VSAN and IVR zones to permit specific flows.

Question 44Implementing and Managing Cisco MDS Switches

Which command creates a PortChannel named san-pc1 that bundles fc1/1 and fc1/2 toward a peer switch?

  1. interface fc1/1, then port-channel 1 name san-pc1
  2. channel-group 1 name san-pc1 on fc1/1
  3. port-channel create san-pc1 members fc1/1,fc1/2
  4. interface port-channel 1, then channel-group 1 force on fc1/1 and fc1/2 Correct answer.

Explanation

A PortChannel is created as a logical interface, and member physical interfaces are added with channel-group <n> force. The force keyword is required because the member ports are already configured.

Question 45Implementing and Managing Cisco MDS Switches

Which feature allows multiple N-ports to log in through a single domain ID on a core switch?

  1. Trunking
  2. N-port virtualization (NPV)
  3. Fabric binding
  4. N-port identifier virtualization (NPIV) Correct answer.

Explanation

NPIV lets a single physical port present multiple fabric logins, each with its own FC ID, so many N-ports can share one domain ID on the core. NPV, by contrast, makes an edge switch appear as a set of N-ports to the core.

Question 46Implementing and Managing Cisco MDS Switches

Which command displays the zoning statistics and the number of zones in the active zone set for VSAN 10?

  1. show zone status vsan 10
  2. show running-config zone vsan 10
  3. show zoneset active vsan 10
  4. show zone statistics vsan 10 Correct answer.

Explanation

show zone statistics reports zoning-related counters and summary information for the VSAN, including active zone set details. It is used to confirm zoning is functioning and to see activity.

Question 47Implementing and Managing Cisco MDS Switches

Which command assigns interface fc1/5 to VSAN 20?

  1. interface fc1/5, then switchport trunk allowed vsan 20
  2. interface fc1/5, then switchport mode F vsan 20
  3. vsan database, then vsan 20 interface fc1/5 Correct answer.
  4. interface fc1/5, then vsan 20

Explanation

Port membership is configured in the vsan database submode with the vsan <id> interface <port> syntax. The interface-level vsan command is not used for this purpose on NX-OS.

Question 48Implementing and Managing Cisco MDS Switches

An administrator wants a zone member defined by interface rather than by pWWN so that replacing a host HBA keeps the zoning intact. Which member type is used?

  1. interface Correct answer.
  2. device-alias
  3. pwwn
  4. fcid

Explanation

An interface-based zone member references the switch port (for example fc1/5) instead of the device WWN, so replacing the HBA on that port does not require a zoning change. WWN-based members would need updating when the HBA changes.

Question 49Implementing and Managing Cisco MDS Switches

Which command activates a zone set named prod_zones in VSAN 10?

  1. zone activate prod_zones vsan 10
  2. zoneset enable prod_zones vsan 10
  3. zoneset activate prod_zones vsan 10 Correct answer.
  4. zoneset activate name prod_zones vsan 10

Explanation

Activation uses the zoneset activate <name> vsan <id> syntax, which makes that zone set the enforced policy for the VSAN. The name keyword is not part of the command.

Question 50Implementing and Managing Cisco MDS Switches

A SAN administrator needs to configure a new Cisco MDS switch so that its principal switch election prefers this device over the existing core switch in VSAN 10. Which action accomplishes this?

  1. Set the VSAN 10 priority to a higher numeric value than the current principal switch
  2. Set the VSAN 10 priority to a lower numeric value than the current principal switch Correct answer.
  3. Assign a static domain ID of 1 to the new switch in VSAN 10
  4. Disable FSPF on the ISL connecting the two switches in VSAN 10

Explanation

Principal switch selection in a VSAN is decided by the configured priority, and the switch with the numerically lowest priority wins the election. The default priority is 128, so setting a value below the current principal's priority makes the new switch preferred. Domain ID assignment and FSPF settings do not influence which switch becomes principal.
