VMware 3V0-25.25 Online Questions & Answers

• Question 31:

  An administrator encountered a failure with one of the NSX Managers in a VCF Fleet.

  The administrator has successfully re-deployed an NSX Manager from SFTP backups.

  However, after replacing the failed manager node, the new node joins successfully, but the cluster status remains "Degraded".

  - The get cluster status command on the leader still shows the old UUID with state "REMOVED".

  What is the command to resolve the issue?

  A. detach node <new-uuid>
  B. delete node <old-uuid>
  C. detach node <old-uuid> then delete node <old-uuid>
  D. detach node <old-uuid>
  D. detach node <old-uuid>

• Question 32:

  DRAG DROP

  An administrator is attempting to confirm the successful transmission between an internal VM to an external destination.

  An ICMP request packet is being sent from Sa-transit-web-01 to the Student Desktop in the diagram.

  Drag and Drop the commands output into their appropriate originating NSX object.

  Select and Place:

  

  

• Question 33:

  An architect is reviewing a VCF networking design before deployment. The design includes NSX, a Tier-0 gateway, several Tier-1 gateways, and an Edge cluster.

  Which statement best describes the relationship among these components?

  A. NSX provides the networking platform, Tier-1 gateways connect workload segments, the Tier-0 gateway connects northbound, and the Edge cluster supplies centralized gateway resources
  B. NSX is used only for backups, Tier-1 gateways are physical routers, the Tier-0 gateway stores images, and the Edge cluster is optional documentation
  C. NSX requires every workload segment to connect directly to a physical router, while Tier-0 and Tier-1 gateways are used only for management access
  D. NSX replaces routing with layer 2 switching only, so Tier-0 gateways and Edge clusters are not part of north-south connectivity
  A. NSX provides the networking platform, Tier-1 gateways connect workload segments, the Tier-0 gateway connects northbound, and the Edge cluster supplies centralized gateway resources

• Question 34:

  When attempting to deploy or expand an edge cluster from an administrator encounters a failure: "Failed to validate the BGP Route Distribution". Prior to calling support, the administrator attempts to troubleshoot the issue.

  How should the administrator troubleshoot this issue?

  A. Log into the NSX manager and examine the nsxapi.log for errors.
  B. Log into the Tier-1 router to verify that route distribution is being enabled.
  C. Log into the vCenter and verify there are no errors or warnings from the NSX manager.
  D. Log into the edge node of the Tier-0 being deployed and check the routes being learnt.
  D. Log into the edge node of the Tier-0 being deployed and check the routes being learnt.

• Question 35:

  HOTSPOT

  An administrator implements route leaking between the Tier-0 gateways to enhance east/west communication because the physical L3 devices are oversubscribed.

  Where should route-maps be configured based on the architecture observed in the diagram?

  

  

• Question 36:

  How should the Global Managers (GMs) and Local Managers (LMs) be distributed to ensure high availability and optimal performance in a multi-site NSX Federation deployment comprised of three sites? (Choose two.)

  A. Each NSX site must have its own LM cluster that reports to the GM.
  B. LMs are only needed on the primary site. Secondary sites can manage their local data plane directly via the GM.
  C. LMs should only be deployed as single nodes to reduce overhead.
  D. The GM cluster should be deployed across three sites.
  E. The GM should be a single appliance placed in a central cloud environment to simplify connectivity, relying on vSphere HA for availability.
  A. Each NSX site must have its own LM cluster that reports to the GM.
  D. The GM cluster should be deployed across three sites.

• Question 37:

  An administrator created a new Tier-1 Gateway and is attempting to change the connected gateway for a deployed segment to use the new gateway. In the UI, when the administrator clicks the Connected Gateway dropdown, the new Tier-1 gateway is not shown as an available gateway.

  What would prevent the new Tier-1 gateway from showing in the list of available gateways?

  A. The Tier-1 Gateway is not connected to an NSX Edge Cluster.
  B. The Tier-1 Gateway connectivity policy is set to "None".
  C. The Tier-1 Gateway and NSX Segment are in different transport zones.
  D. The Tier-1 Gateway and NSX Segment are connected to different Tier-0 Gateways.
  C. The Tier-1 Gateway and NSX Segment are in different transport zones.

• Question 38:

  An administrator is enabling IPv6-to-IPv4 communication for workloads hosted in an NSX environment.

  The workloads use IPv6-only addressing, but the external systems they must reach are IPv4-only. To provide this translation service, the administrator decides to configure NAT64.

  Which two following characteristics about NAT64 are true? (Choose two.)

  A. NAT64 is stateless and requires gateways to be deployed in active-standby mode.
  B. NAT64 requires the Tier-1 gateway to be configured in active-standby mode.
  C. NAT64 is supported on Tier-1 gateways only.
  D. NAT64 is supported on Tier-0 and Tier-1 gateways.
  E. NAT64 requires the Tier-1 gateway to be configured in active-active mode.
  B. NAT64 requires the Tier-1 gateway to be configured in active-standby mode.
  D. NAT64 is supported on Tier-0 and Tier-1 gateways.

• Question 39:

  An administrator is investigating packet loss reported by workloads connected to VLAN segments in an

  NSX environment. Initial checks confirm:

  - All VMs are powered on

  - VLAN segment IDs are consistent across transport nodes.

  - Physical switch configurations are correct.

  Which two NSX tools can be used to troubleshoot packet loss on VLAN Segments? (Choose two.)

  A. Flow Monitoring
  B. Traceflow
  C. Packet Capture
  D. Activity Monitoring
  E. Live Flow
  B. Traceflow
  C. Packet Capture

• Question 40:

  An administrator has observed an NSX Local Manager (LM) outage at the secondary Site. However, the NSX Global Manager (GM) in secondary Site remains operational.

  What happens to data plane operations and policy enforcement at the secondary site?

  A. All traffic is blocked until secondary site LM recovers.
  B. Only local policies work; global policies cease to apply on the secondary site.
  C. The data plane operates normally until LM recovery and reconnection.
  D. Secondary site must failover all workloads to Primary site.
  C. The data plane operates normally until LM recovery and reconnection.
