VMware 3V0-25.25 Online Questions & Answers

• Question 41:

  An administrator is troubleshooting east-west network performance between several virtual machines connected to the same logical segment. The administrator inspects the internal forwarding tables used by ESXi and notices that different tables exist for MAC and IP mapping.

  Which table on an ESXi host is used to determine the location of a particular workload for frame forwarding?

  A. ARP Table
  B. FIP Table
  C. TEP Table
  D. MAC Table
  D. MAC Table

• Question 42:

  DRAG DROP

  An administrator has noticed that both the active and standby Global Managers have gone offline.

  What is the correct sequence of events to restore the Global Managers?

  Select and Place:

  

  

• Question 43:

  An administrator is upgrading an existing VMware Cloud Foundation (VCF) environment. An NSX Edge Cluster is required to support north-south traffic for a workload domain.

  How would the administrator initiate the edge cluster deployment?

  A. From the VCF Installer.
  B. Through VCF Operations Fleet Manager.
  C. From vCenter Network Connectivity wizard.
  D. From the vCenter Server Appliance Management Interface (VAMI).
  B. Through VCF Operations Fleet Manager.

• Question 44:

  An administrator has noticed an issue in a freshly deployed VMware Cloud Foundation (VCF) environment where the BGP neighborship between the Tier-0 gateway and a physical router remains in the Idle state.

  Pings between the uplink IPs are successful.

  What is the issue?

  A. Autonomous System number mismatch.
  B. Distributed Firewall blocking traffic.
  C. Geneve tunnel down.
  D. Overlay MTU too low.
  A. Autonomous System number mismatch.

• Question 45:

  Which two statements describe the recommended strategy for configuring and synchronizing security policies across Federated NSX sites? (Choose two.)

  A. Consistency is achieved by ensuring all security groups have the exact same name on every Federated site's Local Manager (LM).
  B. Security policies, such as Distributed Firewall rules and security groups, must be defined as global policies on the Global Manager (GM).
  C. The Global Manager only synchronizes networking (L2/L3) configurations. Security rules must be configured separately on each site.
  D. Local Managers (LMs) can define local policies, but any global policies defined on the GM always take precedence over the local ones.
  E. Security policies should be defined locally on each LM and only synchronized manually by an administrator to prevent accidental conflicts.
  B. Security policies, such as Distributed Firewall rules and security groups, must be defined as global policies on the Global Manager (GM).
  D. Local Managers (LMs) can define local policies, but any global policies defined on the GM always take precedence over the local ones.

• Question 46:

  An administrator is troubleshooting intermittent connectivity failures between two workloads connected to NSX VLAN segments using Traceflow. In-band Network Telemetry (INT) has been enabled in the NSX Global Configuration.

  How does Traceflow identify issues in a VLAN network?

  A. Injects ICMP traffic into the data plane and observes the results in the control plane.
  B. Injects synthetic traffic into the data plane and observes the results in the control plane.
  C. Traceflow cannot be enabled to analyze VLAN network segments in NSX.
  D. Compares intended network state in the control plane with Tunnel End Point (TEP) keepalives in the data plane.
  B. Injects synthetic traffic into the data plane and observes the results in the control plane.

• Question 47:

  Which two checks are most relevant when a workload connected to an NSX segment cannot reach networks beyond a Tier-0 gateway? (Choose two.)

  A. Confirm that the segment has a valid gateway path through a Tier-1 or Tier-0 gateway
  B. Confirm that the Tier-0 gateway has a route or dynamic routing path toward the upstream network
  C. Confirm that the workload VM name matches the Tier-0 gateway name
  D. Confirm that every Tier-1 gateway has the same display name as the Tier-0 gateway
  E. Confirm that an additional disconnected segment exists for the same workload
  A. Confirm that the segment has a valid gateway path through a Tier-1 or Tier-0 gateway
  B. Confirm that the Tier-0 gateway has a route or dynamic routing path toward the upstream network

• Question 48:

  A sovereign cloud provider has a VMware Cloud Foundation (VCF) stretched Workload Domain across two data centers (AZ1 and AZ2), where site connectivity via Layer 3 is provided by the underlay.

  The following NSX details are included in the design:

  - Each site must host its own local NSX Edge Cluster for availability zones.

  - Tier-0 gateways must be configured in active/active mode with BGP ECMP to local top-of-rack switches.

  - Inter-site Edge TEP traffic must not cross the inter-DC link.

  - SDDC Manager is used to automate NSX deployment.

  During deployment of the Edge Cluster for AZ2, the SDDC Manager workflow fails because the Edge transport nodes' TEP IPs are not reachable from the ESXi transport nodes.

  Which step ensures correct Edge Cluster deployment in multi-site stretched domains?

  A. Disable the liveness check during Edge deployment in SDDC Manager.
  B. Configure BGP neighbors before deploying the Edge Cluster.
  C. Reuse the TEP IP pool from AZ1.
  D. Create an AZ2-specific Edge TEP IP pool and map it to the AZ2 uplink profile before deploying the Edge Cluster.
  D. Create an AZ2-specific Edge TEP IP pool and map it to the AZ2 uplink profile before deploying the Edge Cluster.

• Question 49:

  HOTSPOT

  The network team has decided to use a single Edge Cluster to provide Tier-0 A/A Gateway routing and Tier-1 Gateway A/S services.

  The active Tier-1 with a Gateway Firewall service is on EN2.

  Which highlighted options will show the ECMP paths used by that Tier-1 GFW?

  

  

• Question 50:

  An administrator has deployed a new VMware Cloud Foundation (VCF) management domain. To be compliant with company policy, backups must be configured to occur anytime a change is made to the

  NSX configuration.

  How can the administrator ensure that complete configuration backups are captured every time a change occurs?

  A. Configure an alarm to detect configuration changes and automatically trigger a complete configuration backup.
  B. No action is required as by default NSX will automatically perform a complete backup every time a change is made to the configuration.
  C. Configure a cron job on the NSX Manager to automatically perform an incremental backup of the NSX configuration every hour.
  D. Create a recurring backup schedule and explicitly indicate that backups should be captured anytime the configuration changes.
  D. Create a recurring backup schedule and explicitly indicate that backups should be captured anytime the configuration changes.
