VMware NSX-T Data Center for Operators — Question 62

A cloud administrator is using VMware HCX to migrate application workloads between an on-premises data center and a VMware Public Cloud instance. The layer 2 extension (L2E) capability of VMware HCX is being used to extend a number of on-premises network segments into the cloud to avoid IP re-addressing concerns.

When the cloud administrator tries to extend a native layer 2 network segment from the cloud back into the on-premises data center, an error is encountered and the extension fails.

What should the administrator do to enable network extension from the cloud side to on-premises in this scenario?

Answer options

• A. Enable reverse L2E in the advanced configuration menu of HCX. Make the appropriate change and re-deploy the HCX Service Mesh.
• B. Ensure that the on-premises environment has at minimum a VMware vSphere Distributed Switch with version 6.5 configured.
• C. Enable reverse L2E in the advanced configuration menu of HCX. Make the appropriate change, re-deploy the on-premises HCX Manager and re-pair the sites together.
• D. Install VMware NSX-T into the on-premises data center.

Correct answer: A

Explanation

The correct answer is A because enabling reverse L2E in the advanced configuration is essential for the extension to function properly in the reverse direction. Option B is incorrect because having a VMware vSphere Distributed Switch is not sufficient for enabling reverse L2E. Option C incorrectly suggests redeploying the on-premises HCX Manager, which is unnecessary for this scenario. Option D is irrelevant since installing VMware NSX-T does not directly address the reverse L2E requirement.
