2V0-13.25 Dumps With Exact Questions and Answers

Comprehensive and Detailed Explanation (Based on VMware Cloud Foundation 9.0.1 Design Guide):

The VCF 9.0.1 Design Guide and vSphere HA Design Best Practices define N+1 as a configuration where one additional host is reserved to ensure full workload recovery in case of a host failure. It specifies:

“To satisfy N+1 availability, the number of cluster hosts must exceed the required workload hosts by one to provide failover capacity.”

Therefore, for five resource-intensive VMs, a six-host cluster (D) ensures that in case of one host failure, performance and availability SLAs are maintained.

In addition, using automated placement rules (A) (e.g., anti-affinity rules) ensures that mission-critical VMs are separated across hosts, minimizing risk of concurrent failure. Resource pools (B) only control scheduling priority and do not affect availability, and keeping all VMs together (C) violates redundancy principles.

BGP loop prevention relies on unique AS numbers. If the same AS is reused, routes may be dropped. In NSX VPC designs, assigning a unique private AS per Tier-0 gateway ensures clean routing without triggering loop detection.

A: Timer adjustment affects convergence, not loop detection.

C: iBGP with physical routers is non-standard and doesn’t solve the loop issue.

D: TEP traffic is unrelated to BGP routing loops.

According to the VMware Cloud Foundation 9.0.1 Network Latency and Fleet Expansion Guidelines, the maximum supported latency between VCF instances in a fleet is 100ms round-trip (refer to VCF-NET-REQD-LAT-006). Any latency exceeding this threshold can impact VCF Operations synchronization, NSX Federation communication, and lifecycle management tasks.

In this scenario, Datacenter A (90ms RTT) is within the 100ms limit, whereas Datacenter B (120ms RTT) exceeds it. Therefore, Datacenter A can host a new VCF instance within the existing VCF fleet, maintaining fleet-level manageability and minimal footprint. Datacenter B, on the other hand, requires a separate VCF fleet due to latency exceeding the supported limit.

This design ensures operational continuity while minimizing hardware footprint by using a hybrid deployment strategy — a fleet instance in Datacenter A and a standalone fleet in Datacenter B.
