An LTM Specialist configures an HTTP monitor as follows:
ltm monitor http stats_http_monitor {
defaults-from http
ltm monitor http stats_http_monitor {
defaults-from http

An LTM device is monitoring pool members on port 80. The LTM device is using an HTTP monitor with a send string of GET / and a blank receive string. What would cause the pool members to be marked down?
6.
An LTM device is monitoring three pool members. One pool member is being marked down. What should the LTM Specialist enable to prevent the server from being flooded with connections once its monitor determines it is up?
7.
An LTM device is serving an FTP virtual server that has three pool members. The FTP pool members are monitored via TCP port 21. Customers are reporting that they are able to log in, but are sometimes unable to upload files to the server. Which monitor should the LTM Specialist configure to verify that the servers can handle file uploads?
8.
An LTM Specialist is receiving reports from customers about multiple applications failing to work properly. The LTM Specialist looks at the services running and notices that the bigd process has NOT started. How are monitored LTM device objects marked when the bigd process is stopped?
9.
An LTM Specialist is setting up a monitor for an HTTP 1.1 server. The response to a GET / is:
HTTP/1.1 302 Moved Temporarily
Location: http://www.example.com/new/location.html
Which send string settings should the LTM Specialist use to force a proper response?
HTTP/1.1 302 Moved Temporarily
Location: http://www.example.com/new/location.html
Which send string settings should the LTM Specialist use to force a proper response?
10.
An LTM Specialist defines a receive string in the HTTP monitor and then assigns it to the HTTP pool. The monitor has an interval of 5 seconds and a timeout of 16 seconds. If the receive string is NOT seen in the the HTTP payload after 20 seconds, how does the LTM device mark the monitor status?
