• Question 286:

  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 should the LTM Specialist do to resolve this?

  A. Use the followinG. switch -lc [HTTP::uri]
  B. Use the followinG. switch [string tolower [HTTP::uri]]
  C. Set the "Case Sensitivity" option of each member to "None".
  D. Select the "Process Case-Insensitivity" option for the virtual server.
  B. Use the followinG. switch [string tolower [HTTP::uri]]

• Question 287:

  There is a fault with an LTM device load balanced trading application that resides on directly connected VLAN vlan-301. The application virtual server is 10.0.0.1:80 with trading application backend servers on subnet 192.168.0.0/25. The LTM Specialist wants to save a packet capture with complete payload for external analysis.

  Which command should the LTM Specialist execute on the LTM device command line interface?

  A. tcpdump -vvv -w /var/tmp/trace.cap 'net 192.168.0.0/25'
  B. tcpdump -vvv -s 0 -w /var/tmp/trace.cap 'net 192.168.0.0/25'
  C. tcpdump -vvv -nni vlan-301 -w /var/tmp/trace.cap 'net 192.168.0.0/25'
  D. tcpdump -vvv -s 0 -nni vlan-301 -w /var/tmp/trace.cap 'net 192.168.0.0/25'
  D. tcpdump -vvv -s 0 -nni vlan-301 -w /var/tmp/trace.cap 'net 192.168.0.0/25'

• Question 288:

  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. A virtual server connection limit has been reached.
  B. The host at the other end terminated the TCP connection.
  C. The LTM device reset the connection because no pool members are available.
  D. 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.

• Question 289:

  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?

  A. offline
  B. unknown
  C. available
  D. unavailable
  E. forced offline
  A. offline

• Question 290:

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