Sample question 1 — Troubleshooting and Repairing
After a host outage, HA restarted nearly every guest in the cluster. One payments service stayed down, and its entry shows only that no valid placement could be found. Which configuration detail should the administrator inspect first?
- A. The guest's scheduled backup window and whether it overlapped the outage.
- B. The order in which the cluster's guests were listed for restart priority.
- C. A required host affinity rule that still names the host that failed.
- D. The size of the guest's memory reservation compared with the cluster's spare capacity.
Answer: C. Option C is correct because a required affinity rule pins the guest to one host, so once that host is unavailable HA finds no valid placement and leaves the service down until the rule is relaxed or the host returns. Option D is incorrect because a resource shortfall would usually produce a capacity message rather than the placement failure reported here. Option A describes a backup schedule that does not influence which host a guest may use. Option B affects the sequence of restarts, and a priority choice would not stop the service from starting eventually.
