A company uses a complex piece of client software that connects to one or more virtual servers (VS) hosted on an LTM device. The client software is experiencing issues. An LTM Specialist must determine the cause of the problem.
The LTM Specialist is seeing a client source IP of 168.210.232.5 in the tcpdump. However, the client source IP is actually 10.123.17.12.
Why does the IP address of 10.123.17.12 fail to appear in the tcpdump?

• A.The individual's data stream is being routed to the LTM device by a means other than the default route.
• B.Network Address Translation (NAT) has occurred in the path between the client and the LTM device.
• C.The Secure Network Address Translation (SNAT) pool on the virtual server is activated.
• D.The LTM device performed NAT on the individual's IP address.

A web application requires knowledge of the client's true IP address for logging and analysis purposes. Instances of the application that can decode X-Forwarded-For HTTP headers reside in pool_a, while pool_b instances assume the source IP is the true address of the client.
Which iRule provides the proper functionality?

• A.when HTTP_DATA {
  if {[HTTP::header exists X-Forwarded-For]}{
  pool pool_a
  } else {
  pool pool_b
  }
  }
• B.when HTTP_REQUEST { if {[HTTP::header exists X-Forwarded-For]}{ pool pool_a } else { pool pool_b } }
• C.when HTTP_OPEN { if {[HTTP::header exists X-Forwarded-For]}{ pool pool_a } else { pool pool_b } }
• D.when HTTP_RESPONSE {
  if {[HTTP::header exists X-Forwarded-For]}{
  pool pool_a
  } else {
  pool pool_b
  } }

An LTM Specialist realizes that a datacenter engineer has changed the console baud rate.
Which command determines the current baud rate via the command line interface?

• A.tmsh show /ltm console
• B.tmsh show /sys console
• C.tmsh list /net baud-rate
• D.tmsh list /sys baud-rate

A virtual server for a set of web services is constructed on an LTM device. The LTM Specialist has created an iRule and applied this iRule to the virtual server:
when HTTP_REQUEST {
switch [HTTP::uri] {
"/WS1/ws.jsp" {
log local0. "[HTTP::uri]-Redirected to JSP Pool"
pool JSP
}
default { log local0. "[HTTP::uri]-Redirected to Non-JSP Pool"
pool NonJSP
}
}
}
However, the iRule is NOT behaving as expected. Below is a snapshot of the log:
/WS1/ws.jsp-Redirected to JSP Pool
/WS1/ws.jsp-Redirected to JSP Pool
/WS1/ws.jsp-Redirected to JSP Pool
/WS1/WS.jsp-Redirected to Non-JSP Pool
/ws1/WS.jsp-Redirected to Non-JSP Pool
/WS1/ws.jsp-Redirected to JSP Pool
/ws1/ws.jsp-Redirected to Non-JSP Pool
What is the problem?

• A.The condition in the iRule is case sensitive.
• B.The pool members of both pools need to be set up as case-insensitive members.
• C.The "Process Case-Insensitivity" option for the virtual server needs to be selected.
• D.The 'switch' command in the iRule has been used incorrectly.

Internet clients connecting to a virtual server to download a file are experiencing about 150 ms of latency and no packet loss.
Which built-in client-side TCP profile provides the highest throughput?

• A.tcp-wan-optimized
• B.tcp-legacy
• C.tcp-lan-optimized
• D.tcp
