VMware 3V0-25.25 Online Practice Questions and Exam Preparation

VMware 3V0-25.25 Online Questions & Answers

• Question 1:

  A Tier-0 gateway uses two upstream routers for redundant external connectivity. The operations team wants both upstream paths to be usable at the same time when the routing policy allows equal paths.

  Which routing behavior supports that design goal?

  A. Equal-cost multipath routing across the eligible upstream paths
  B. A single static route with one permanently preferred next hop
  C. A disconnected Tier-1 gateway for each workload segment
  D. A separate isolated overlay segment for each upstream router
  A. Equal-cost multipath routing across the eligible upstream paths

• Question 2:

  DRAG DROP

  An administrator is responsible for managing a VMware Cloud Foundation (VCF) Private Cloud consisting of a single VCF Fleet with a single Workload Domain.

  The administrator has been tasked with configuring NSX to support the new Virtual Desktop Infrastructure (VDI) solution that allows users to securely access a mainframe-. based application located on the physical network.

  The VDI solution will use a dedicate DHCP solution for each of the the desktop pool segments and static addresses for all.

  VDI management components.

  The administrator completes the following steps towards configuring DHCP:

  1. Creates a new tier-1 gateway (vdi-tier-1) and links it to the tier-0 gateway (gw-tier-0).

  2. Creates one new segment for vdi management (vdi-seg-01) and connects it to vdi-tier-1.

  3. Creates two new segments for virtual desktops (vdi-seg-02 and vdi-seg-03) and connects them to vdi-tier-1.

  Drag and drop the six steps from the list of Possible Steps on the left and place them in order in to the Solution Steps. (Choose six.)

• Question 3:

  An administrator must provide North/South connectivity for a VPC. The fabric exposes a distributed external VLAN across all ESX hosts. But, the only BGP peer to the core is on a VLAN only accessible on the Edge Cluster.

  Which design is required?

  A. Use a VPC Tier-0 Gateway in active/active mode with distributed eBGP peering.
  B. Distributed Transit Gateway with an EVPN route reflector on the transport nodes.
  C. Centralized Transit Gateway on the Edge Cluster.
  D. Deploy a Provider Tier-1 with BGP and connect the VPC Transit Gateway via route leaking.
  C. Centralized Transit Gateway on the Edge Cluster.

• Question 4:

  An administrator is configuring an NSX segment used by a nested hypervisor deployment where an ESXi VM runs on an ESXi host and multiple VMs run inside the ESXi VM.

  Which segment profile must be created to satisfy the request?

  A. IP Discovery
  B. Security
  C. MAC Discovery
  D. Spoof Guard
  C. MAC Discovery

• Question 5:

  An administrator is troubleshooting why workloads in NSX cannot reach the external network 10.100.0.0/16.

  The Tier-0 Gateway is in Active/Active mode and has the following configuration:

  - Uplink-1 (VLAN 100): 192.168.100.0/24 -> router R1 at 192.168.100.1

  - Uplink-2 (VLAN 101): 192.168.101.0/24 -> router R2 at 192.168.101.1

  - A static route for 10.100.0.0/16 was added with both next-hops (192.168.100.1 and 192.168.101.1).

  - The Scope of this route is set to Uplink-1.

  Symptoms:

  - Virtual Machines (VMs) cannot reach 10.100.0.0/16.

  - Traceroute from the VM stops at the Tier-0 gateway with "Destination Net Unreachable"

  - Pings from the Edge nodes to both 192.168.100.1 and 192.168.101.1 are success.

  What explains why workloads in NSX cannot reach the external network?

  A. Static routes do not support Equal Cost Multi-Pathing (ECMP) in NSX.
  B. The static route Scope is set to only one uplink interface, but the next-hops are on two different VLANs.
  C. The next-hops should have been configured as the Tier-0's own uplink IPs instead of the routers IPs.
  D. The physical routers are missing return routes.
  B. The static route Scope is set to only one uplink interface, but the next-hops are on two different VLANs.

• Question 6:

  An administrator is preparing to deploy a new workload domain that will host vSphere Kubernetes Service (VKS) clusters. Before configuring the network for the Kubernetes clusters, the administrator needs to create a Tier-0 Gateway to handle North/South connectivity.

  What is the requirement for creating a Tier-0 Gateway for use with a workload domain that is running the vSphere Kubernetes service (VKS) with VPC?

  A. The Tier-0 Gateway route map must contain an IP prefix with only a deny rule.
  B. The Tier-0 Gateway must be configured in Non-Preemptive failover mode.
  C. The Tier-0 Gateway must be configured in Active/Standby mode.
  D. The Tier-0 Gateway must have IPv6 enabled.
  C. The Tier-0 Gateway must be configured in Active/Standby mode.

• Question 7:

  HOTSPOT

  The administrator is working to ascertain the encapsulation of GENEVE by reviewing the capture on Wireshark.

  The administrator instructed VM-1 to send a continuous ICMP request directed at VM-2.

  Click to highlight where the administrator should observe the GENEVE encapsulated packet.

  

  

• Question 8:

  An administrator is configuring Border Gateway Protocol (BGP) routing on a Tier-0 Gateway to optimize north-south traffic flow between the NSX environment and multiple upstream physical routers.

  The environment includes two external connections that advertise overlapping routes to the same destination networks.

  To ensure predictable and efficient routing behavior, the administrator decides to manipulate specific BGP attributes on outbound advertisements and inbound route updates.

  What are two valid BGP Attributes that can be used to influence the route path traffic will take? (Choose two.)

  A. BFD
  B. Cost
  C. AS-Path Prepend
  D. MED
  C. AS-Path Prepend
  D. MED

• Question 9:

  The administrator is implementing a multi-location VMware Cloud Foundation (VCF) environment. The design requires centralized security and networking policies across multiple VCF instances.

  What action must the administrator take to satisfy the requirements?

  A. Deploy a Global Manager cluster manually.
  B. Deploy a Local Manager (LM) cluster using VCF Operations.
  C. Use SDDC Manager to deploy a Global Manager cluster.
  D. Use VCF Installer to deploy a Local Manager (LM) cluster.
  C. Use SDDC Manager to deploy a Global Manager cluster.

• Question 10:

  An architect needs to allow users to deploy multiple copies of a test lab with public access to the internet.

  The design requires the same machine IPs be used for each deployment.

  What configuration will allow each lab to connect to the public internet?

  A. Configure DNAT rules on the Tier-1 gateway.
  B. Configure isolation on the NSX segment.
  C. Configure firewall rules to isolate the traffic going to the public internet.
  D. Configure SNAT rules on the Tier-0 gateway.
  D. Configure SNAT rules on the Tier-0 gateway.
