For a web service running on port 80, which monitor would verify standard HTTP availability?

• A. HTTP-ECV on port 80
• B. HTTP on port 99
• C. HTTP on port 80
• D. HTTP-ECV on port 99

Answer: (C)

Testing basic HTTP availability means confirming the service responds on its standard port with a normal HTTP reply. The default port for HTTP traffic is port 80, so using a monitor that checks HTTP on port 80 exercises the service in the simplest, most common way and verifies it is reachable and answering requests. HTTP-ECV adds Extended Content Verification, which checks specific content in the response. That extra validation is useful when you need to ensure the response is not only reachable but also correct, but it’s more than what’s needed for basic availability. Nonstandard ports like port 99 would only apply if the service actually listens there, which isn’t the normal HTTP configuration. Since the web service runs on port 80, the HTTP monitor on port 80 is the appropriate choice.
