VMware vSphere 7.x Advanced Design (VCAP-DCV Design 2021) — Question 32

An architect is tasked with recommending a solution for a company that is running out of VLANs. Currently the company is running two separate data centers based on vSphere including an Enterprise Plus license. In the first data center, the problem was solved by using VMware NSX and overlay network. In the second data center, there is currently no VMware NSX implementation in place and no budget for additional licenses.
What should the architect recommend as a potential solution to provide support for additional VLANs?

Answer options

• A. Separate Distributed Virtual Switches (DVS)
• B. Private VLANs (PVLAN)
• C. Virtual Guest Tagging (VGT)
• D. vSwitch VLAN Tagging (VST)

Correct answer: B

Explanation

The correct answer is Private VLANs (PVLAN), as they allow multiple VLANs to exist within a single VLAN while providing isolation between them, thus addressing the VLAN limitation without the need for additional licenses. The other options either do not provide the required VLAN support effectively or may involve more complexity and potential costs, which the company cannot afford.
