Given the iRule:
when HTTP_REQUEST { if {([HTTP::username] ne "") and ([HTTP::password] ne "") } { log local0. "client ip [IP::remote_addr] credentials provided [HTTP::username] [HTTP::password]"} else { pool old_application_pool }
} The associated virtual server has a default pool named new_application_pool.
Which functionality does the iRule provide?

• A.Allows clients without credentials to access the old_application_pool and logs the attempted access of clients without credentials to the new_application_pool.
• B.Allows clients with credentials to access the old_application_pool and logs the attempted access of clients with credentials to the new_application_pool.
• C.Allows clients without credentials to access the old_application_pool and logs the access of clients with credentials to the new_application_pool.
• D.Allows clients with credentials to access the old_application_pool and logs the access of clients without credentials to the new_application_pool.

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 is tasked with finding the cause of the problem.
The LTM Specialist has the tcpdump extract and knows the client software has at least one connection to a VS on port 1990. However, when a tcpdump runs on the internal VLAN, there is no record of port 1990 in the tcpdump.
Why is there no record of port 1990 in the tcpdump?

• A.Port 1990 is a well-known port, so its use is restricted.
• B.The LTM device performs a Network Address Translation (NAT).
• C.The LTM device drops the connection.
• D.The LTM device performs a Port Address Translation (PAT).
• E.Explanation:

  The LTM Specialist has the tcpdump extract and knows the client source IP is
  168.210.232.5.
  Assuming no wildcard virtual servers, how many distinct virtual servers does the client connect to on the LTM device?
  A.2
  B.3
  C.4
  D.6

-- Exhibit -Refer to the exhibit. 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 LTM device performed NAT on the individual's IP address.
• D.The Secure Network Address Translation (SNAT) pool on the virtual server is activated.

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