An LTM device has been configured to log the reasons for generating TCP RST packets.
The following log entry occurs:
"01230140:3: RST sent from 192.168.1.100:80 to 192.168.1.124:39272, [0x112d82a:1721] {peer} TCP RST from remote system."
Which condition will trigger this log entry?

• A.The LTM device has reached the maximum number of allowed attempts to send the data segment to the affected TCP connection.
• B.The host at the other end terminated the TCP connection.
• C.A virtual server connection limit has been reached.
• D.The LTM device reset the connection because no pool members are available.

An LTM Specialist is troubleshooting a problem on an eCommerce website. The user browses the online store using port 80, adding items to the shopping cart. The user then clicks the "Checkout" button on the site, which redirects the user to port 443 for the checkout process. Suddenly, the user's shopping cart is shown as empty. The shopping cart data is stored in memory on the server, and the default source address persistence profile is used on both virtual servers.
How should the LTM Specialist resolve this issue?

• A.Enable SNAT Automap on both virtual servers.
• B.Add an HTTP profile to both virtual servers.
• C.Create a custom persistence profile and enable "Map Proxies."
• D.Create a custom persistence profile and enable "Match Across Services."

The LTM administrator looks at the connection table with a filter on one of the client IP addresses currently connected using the command "tmsh show sys connection cs-clientaddr 10.0.20.1"
with the following results:
10.0.20.1:60048 10.0.20.88:80 10.0.20.1:60048 172.16.20.1:80 tcp 3 (tmm: 0) 10.0.20.1:60050 10.0.20.88:80 10.0.20.1:60050 172.16.20.3:80 tcp 3 (tmm: 0) 10.0.20.1:60047 10.0.20.88:80 10.0.20.1:60047 172.16.20.2:80 tcp 3 (tmm: 0) 10.0.20.1:60049 10.0.20.88:80 10.0.20.1:60049 172.16.20.1:80 tcp 3 (tmm: 0)
What is the solution to the problem?

• A.Modify the setup of the monitor bound to the pool used by the application.
• B.Synchronize the clock of the LTM device with NTP.
• C.Modify the load balancing method attached to the pool.
• D.Set up an HTTP cookie insert profile in the virtual server.

An HTTP monitor always marks the nodes in the pool as down. The monitor's definition and the HTTP headers from the monitor request and response are provided.
What is the issue?

• A.The monitor is NOT configured to follow the redirect.
• B.The send string is incorrect.
• C.The monitor timeout is too short.
• D.The response is compressed.

Which iRule statement demotes a virtual server from CMP?

• B.set static::foo 123
• C.[ class match $HTTP_CONTENT contains my_data_class ]
• D.persist source_addr 1800
