VMware vSphere 6 Beta — Question 30

What is the effect on NSX Edge virtual machines when NSX Edge high availability is configured but vSphere HA is NOT configured?

Answer options

• A. The active-standby NSX Edge pair will survive one failure. However, the virtual machines must reside on the same host to prevent NSX Edge availability from being compromised.
• B. The active-standby NSX Edge HA pair will survive multiple failures.
• C. The active-standby NSX Edge HA pair will survive one failure. However, if another failure happens before the second Edge appliance is restored, NSX Edge availability can be compromised.
• D. The active-standby NSX Edge HA pair will survive two failures. However, the virtual machines must reside on two different hosts.

Correct answer: C

Explanation

The correct answer is C because while the active-standby NSX Edge HA pair is designed to handle one failure, it is vulnerable if a second failure occurs before recovery of the second Edge appliance. Option A is incorrect as it suggests that NSX Edge availability can be maintained with VMs on the same host, which is not true in a failure scenario. Option B is wrong since the active-standby configuration cannot survive multiple failures without restoring the second appliance. Option D is also incorrect because it inaccurately claims that two failures can be survived.
