What does SnowCD verify regarding HTTP communications?

• A. Verifies that an HTTP response was returned from the HTTP host
• B. Verifies DNS resolution for the host
• C. Verifies TLS certificates of the host
• D. Verifies that the request was sent

Answer: (A)

SnowCD’s HTTP check is an end-to-end health test: it verifies that issuing an HTTP request to the target host actually yields an HTTP response. This confirms the service is reachable and actively processing HTTP traffic, not just that a name resolves or a TLS handshake could occur. Verifying DNS resolution only proves the domain can be translated to an IP, not that the HTTP service is alive. Checking TLS certificates tests security credentials, but not whether the server returns any response. Confirming that a request was sent doesn’t guarantee a response was received. Therefore, the key point SnowCD tests is that an HTTP response is returned from the HTTP host.
