Question Image

The decoded TCPDump capture traces a failing health monitor. The health monitor sends the string displayed in the capture; however, the server response is not as expected. The receive string is set to SERVER IS UP.

What is the solution?

  • A The GET request Host header field requires a host name.
  • B Incorrect syntax in send string. 'HTTP/1.1' should be 'HTTP1.1'.
  • C The /test_page.html does NOT exist on the web server and should be added.
  • D Incorrect syntax in send string. 'Connection: Close' should be 'Connection: Open'.
Explanation

An HTTP/1.1 request needs the intended host value to select the correct virtual host. An empty Host: header can cause the server to use its default virtual host, producing a 404 response instead of the content containing SERVER IS UP. Supplying the host name in the Host header routes the request to the intended site. Connection: close is a valid HTTP connection directive.
