VMware vSAN 8.x Administrator — Question 25

An architect is designing a new VCF solution to meet the following requirements:
The solution must be deployed across two availability zones.
The physical hosts must be installed in a single rack per availability zone.
Workloads running in the cluster must be able to run on hosts in either availability zone.
The architect has decided that to meet these requirements the solution will be deployed using the Single Instance - Multiple Availability Zones VCF Topology.
When considering the design for the network, what should the architect include in the logical design to meet these requirements?

Answer options

• A. A physical network fabric supporting routed networks across the availability zones
• B. A single NSX Overlay Transport Zone for all clusters to carry the traffic between the ESXi hosts
• C. A pair of Cisco routers acting as the gateway within each of the availability zones
• D. A 25-GbE port on each Top of Rack (ToR) switch connected to the ESXi host uplinks

Correct answer: B

Explanation

The correct answer, B, is appropriate because a single NSX Overlay Transport Zone facilitates seamless communication between ESXi hosts across multiple availability zones, which is essential for the given requirements. Option A, while related to network routing, does not specifically address the need for overlay transport. Option C focuses on gateway functionality but does not cover the network design needed for workload mobility. Option D pertains to physical connectivity but is not sufficient for the logical network design needed in this scenario.
