3V0-25.25 Sample Questions

  1. Question 1

    Intermediate

    Plan and Design the VMware Solution · Design an NSX Connectivity Solution (Centralized vs Distributed)

    A Cloud Architect is designing a new VCF 9.0 Workload Domain for a financial institution. The requirements specify that a specific group of latency-sensitive trading applications requires direct host-to-fabric connectivity to minimize hop count and latency. The design must avoid routing traffic through centralized Edge nodes for these specific workloads while maintaining isolation. Which architectural component should the architect select to meet these requirements?

    Answer and explanation

    Correct answer: B

    In VCF 9.0, the NSX Transit Gateway enables a distributed connectivity model. It allows workloads to connect directly from the ESXi host to the physical fabric (host-to-fabric connectivity) using VDS VLAN-backed networking, bypassing the need for centralized Edge nodes and Service Routers (SRs) for routing. This reduces hops and latency, making it ideal for the scenario described.

  2. Question 2

    Advanced

    Install, Configure, Administrate the VMware Solution · Identify the Process Steps for Deploying VMware NSX Federation in VCF

    An administrator is preparing to deploy a multi-site VCF 9.0 solution using NSX Federation. The design calls for a primary site in New York and a secondary site in London. Regarding the deployment of the Global Manager (GM), which statement correctly describes the required procedure?

    Answer and explanation

    Correct answer: C

    Unlike Local Managers which are lifecycle managed by SDDC Manager, the NSX Global Manager (GM) in a VCF Federation deployment is deployed manually as an appliance (OVA/OVF) directly onto vSphere. Once deployed, the Local Managers (managed by VCF) are then registered to this Global Manager.

  3. Question 3

    Beginner

    Install, Configure, Administrate the VMware Solution · Deploy and Manage Virtual Private Cloud (VPC)

    A DevOps team requires a self-service networking environment where they can create their own subnets, define firewall rules, and configure load balancing without submitting tickets to the central IT team. The environment must be isolated but able to route traffic to other internal services. Which VCF 9.0 construct should the administrator provision for this team?

    Answer and explanation

    Correct answer: A

    In VCF 9.0, the Virtual Private Cloud (VPC) is the primary construct for self-service networking. It provides an isolated environment where tenants (via NSX Projects) can manage their own subnets, security policies, and services independently of the underlying infrastructure, mirroring public cloud consumption models.

  4. Question 4

    Intermediate

    Troubleshoot and Optimize the VMware Solution · Identify the Appropriate VCF Tool/Product to Troubleshoot an Issue in NSX

    While troubleshooting a North-South connectivity issue for a specific tenant in a multi-tenant VCF environment, an administrator needs to determine if the packet is being dropped at the Distributed Router (DR) or the Service Router (SR) component of the Tier-1 Gateway.

    Which tool should the administrator use to inject a synthetic packet and visualize the hop-by-hop path through the logical routers?

    Answer and explanation

    Correct answer: D

    NSX Traceflow is the specific tool designed to inject synthetic packets into the network and track their path hop-by-hop across logical switches and routers (DR and SR components). It reports exactly where a packet is dropped or modified (e.g., by a firewall rule or NAT).

  5. Question 5

    Intermediate

    Plan and Design the VMware Solution · Design an NSX Connectivity Solution (Centralized vs Distributed)

    A network architect is designing the upstream physical connectivity for an NSX Edge Cluster that will support high-bandwidth ECMP routing. The design requires that if a single Edge node fails, traffic should failover in less than one second. Which protocol must be configured between the Tier-0 Gateway and the physical routers to meet this requirement?

    Answer and explanation

    Correct answer: B

    Standard BGP keepalive timers are often too slow (default 60s/180s) to meet sub-second failover requirements. Bidirectional Forwarding Detection (BFD) is a high-speed protocol used in conjunction with BGP to detect link or neighbor failures in milliseconds, triggering a rapid routing convergence.

  6. Question 6

    Beginner

    Install, Configure, Administrate the VMware Solution · Create NSX Tier-0 Gateway

    An administrator is configuring a Tier-0 Gateway in a VCF 9.0 environment. The requirement is to maximize North-South throughput by utilizing all available paths across 4 Edge Nodes. Which High Availability (HA) mode must be selected to support Equal Cost Multi-Path (ECMP) routing?

    Answer and explanation

    Correct answer: D

    Active-Active HA mode is required to enable ECMP (Equal Cost Multi-Path) routing. In this mode, all Edge nodes in the cluster (up to 8) can forward traffic simultaneously, aggregating bandwidth. Active-Standby only allows one node to forward traffic at a time.
