Worldwide users from an organization are experiencing intermittent access to a global cloud application. The cloud provider availability dashboard shows all resource availability has been 100% in the last two weeks. No network outages have been reported. Which of the following should the organization's administrator do BEFORE calling the cloud provider?

Question

Accepted Answer

D. Evaluate the DNS to ensure all configurations are correct. DNS is the foundational service that translates application hostnames into routable addresses; a misconfiguration such as incorrect A/CNAME records, TTL conflicts, or replication failures would cause intermittent, geography-dependent access failures that never appear on a cloud provider availability dashboard. Evaluating DNS first rules out a client-side or infrastructure name resolution issue before engaging the provider.

Answer

A. Check the firewall rules on the headquarters site. Firewall rules at headquarters would only affect users at that site, not worldwide users experiencing intermittent failures.

Answer

B. Restart the application and applicable services. Restarting the application is premature and treats a symptom rather than identifying a root cause, especially when provider resources show 100% availability.

Answer

C. Allow all traffic at the cloud provider side from any private IP address. Allowing all traffic from any private IP is a security risk and irrelevant because no network outage has been reported and private IPs do not cross the public internet.
