The LTM Specialist is writing a custom HTTP monitor for a web application and has viewed the content by accessing the site directly via their browser. The monitor continually fails. The monitor configuration is:
ltm monitor http /Common/exampleComMonitor {
defaults-from /Common/http
destination *:*
interval 5
recv "Recent Searches"
send "GET /app/feed/current\?uid=20145 HTTP/1.1\\r\\nHost: www.example.com\\r\\nAccept- EncodinG. gzip, deflate\\r\\nConnection: close\\r\\n\\r\\n"
time-until-up 0
timeout 16
}
A trace shows the following request and response:
Request:
GET /app/feed/current?uid=20145 HTTP/1.1
Host www.example.com
Accept-Encoding gzip, deflate
Connection: close
Response:
HTTP/1.1 302 Moved Temporarily
Date Wed, 17 Oct 2012 18:45:52 GMT
Server Apache
Location https://example.com/login.jsp
Content-Encoding gzip
Content-Type text/html;charset=UTF-8
Set-CookiE. JSESSIONID=261EFFBDA8EC3036FBCC22D991AC6835; Path=/app/feed/current?uid=20145
What is the problem?

  1. The request does NOT include a User-Agent header.
  2. The HTTP monitor does NOT support monitoring jsp pages.
  3. The request does NOT include any cookies and the application is expecting a session cookie.
  4. The request includes an Accept-Encoding so the server is responding with a gzipped result and LTM monitors CANNOT handle gzipped responses.

Answer(s): C



An LTM Specialist configures an HTTP monitor as follows:
ltm monitor http stats_http_monitor {
defaults-from http
destination *:*
interval 5
recv "Health check: OK"
send "GET /stats/stats.html HTTP/1.1\\r\\nHost: www.example.com\\r\\nAccept-EncodinG. gzip, deflate\\r\\nConnection: close\\r\\n\\r\\n"
time-until-up 0
timeout 16
}
The monitor is marking all nodes as down. A trace of the HTTP conversation shows the following:
GET /stats/stats.html HTTP/1.1
Host: www.example.com
Accept-EncodinG. gzip, deflate
Connection: close
HTTP/1.1 401 Authorization Required
DatE. Tue, 23 Oct 2012 19:38:56 GMT
Server: Apache/2.2.15 (Unix)
WWW-AuthenticatE. Basic realm="Please enter your credentials"
Content-LengtH. 480
Connection: close
Content-TypE. text/html; charset=iso-8859-1
Which action will resolve the problem?

  1. Add an NTLM profile to the virtual server.
  2. Add a valid username and password to the monitor.
  3. Use an HTTPS monitor with a valid certificate instead.
  4. Add a backslash before the colon in the receive string.

Answer(s): B

The health monitor is sending the string shown in the capture; however, the server response is NOT as expected. The correct response should be an HTML page including the string 'SERVER IS UP'.
What is the issue?

  1. The /test_page.html does NOT exist on the web server.
  2. Incorrect syntax in send string. 'HTTP1.1' should be 'HTTP/1.1'.
  3. Incorrect syntax in send string. 'Connection: Close' should be 'Connection: Open'.
  4. The wrong HTTP version is specified in the send string. Version 1.2 should be used instead of version 1.1.

Answer(s): B
