2V0-622D Question #25: Real Exam Question with Answer & Explanation
The correct answer is C: If only one of the isolation addresses is reachable, the host will not be marked isolated by HA.. With multiple isolation addresses configured, vSphere HA only marks a host as isolated if all isolation addresses are unreachable, so reachability of any single address keeps the host considered non-isolated.
Question
An administrator would like to configure vSphere HA to use two isolation addresses. How would this affect the behavior of HA?
Options
- AIf both isolation addresses are not reachable, the host will be restarted by the HA agent.
- BIf both isolation addresses are not reachable, the host will use the vCenter Server IP address as a
- CIf only one of the isolation addresses is reachable, the host will not be marked isolated by HA.
- DIf only one of the isolation addresses is reachable, the host will be considered in an isolated by
Explanation
With multiple isolation addresses configured, vSphere HA only marks a host as isolated if all isolation addresses are unreachable, so reachability of any single address keeps the host considered non-isolated.
Common mistakes.
- A. HA does not restart the host itself; it restarts virtual machines running on a host that is deemed failed or isolated, and only after all configured isolation addresses are confirmed unreachable.
- B. vSphere HA does not fall back to using the vCenter Server IP as an isolation address; the isolation detection is strictly based on the explicitly configured isolation response addresses and the default gateway.
- D. If at least one isolation address is reachable, the host is explicitly considered non-isolated by HA logic, which is the opposite of what this choice states.
Concept tested. vSphere HA host isolation detection with multiple addresses
