A SOC analyst is monitoring a REST API that aggregates security events. The analyst notices that the API is returning 503 Service Unavailable. What is the most likely cause?

The API client is using an invalid authentication token.

The API server is temporarily unable to handle the request due to maintenance or overload.

The API client is sending requests too quickly and being rate-limited.

The API endpoint has been permanently moved to a new URL.

A security analyst is building a REST API client that caches threat intelligence reports. The client sends a GET request with an If-None-Match header containing the ETag of the cached report. The API responds with 304 Not Modified. What should the client do?

Download the report again because the server indicated the cached version is stale.

Follow the redirect in the Location header to retrieve the updated report.

Send the request again without the If-None-Match header to force a fresh response.

Use the cached version of the report because the server confirmed it has not changed.

A network automation engineer is designing a REST API client that provisions new firewall policies. The client must handle the following scenarios: (1) a policy is created successfully, (2) a policy already exists, and (3) the API is temporarily overloaded. The engineer wants to implement retry logic. Which combination of HTTP status codes should the client treat as retryable?
