  Correct Answer: B

• Question 26:

  An LTM Specialist needs to use the tmsh command to create a pool named http_pool with member

  10.10.101:80

  on an LTM device. Which expression should the LTM Specialist use?

  A.

  # tmsh create pool http_pool members {10.10.10.101:80}

  B.

  # tmsh create pool http_pool members add {10.10.10.101:80}

  C.

  # tmsh create it pool http_pool members {10.10.10.101:80}

  D.

  # tmsh create itm pool http_pool member {10.10.10.101:80}

  Correct Answer: C

  The option should be wrong, it should ne itm instead of it, the correct command is:tmsh create itm pool http_pool members add (10.10.10.101:80}

• Question 27:

  An LTM Specialist is configuring a client profile to offload processing a new application Company policy

  requires that clients can resume session for up to 30 minutes, but must renegotiate a new session after

  that.

• Question 28:

  An LTM Specialist upgrades the switching infrastructure and the backend servers on the LAN segments.

  The LTM Specialist notices a 20% memory usage increase on the BIG-IP device while handling the same

  number of concurrent connections.

  A comparison of statistics pre-upgrade and post-upgrade shows a significant reduction on the following:

  -RTT between the BIG-IP device and the backend servers

  -Packet drops in the switch

  Time to First Byte (TTFB)

  The LTM Specialist is concerned with the scalability of the number of concurrent connections with the new

  memory usage.

  Which setting should be changed to reduce the memory usage on the BIG-IP device?

  A. Reduce the proxy buffer high setting on the server-side TCP profile

  B. Increase the receive window of the client-side TCP profile

  C. Increase the proxy buffer high setting on the server-side TCP profile

  D. Reduce the idle of the client-side TCP profile

  Correct Answer: A

  After adjusting the architecture, the network quality becomes better. With the connection unchanged the memory usage increase by 20%. It means that the sending speed of the server is higher than the receiving speed of the client. F5 caches more content on the memory and causes the memory usage to....

• Question 30:

  An LTM Specialist needs to force only FTP traffic, sourced from subnet 10.10.10.0/24 to virtual server

  10.10.20.1 to the new FTP1 server. The following virtual servers are configured on the LTM device: Traffic sourced from 10.10.10/24 must use the specific pool member for load balancing. Which configuration change is needed to meet the requirements?

  A. Create a new virtual server for traffic sourced from 10.10.10.0/24 on port 80 that is destined to 10.10.20.1/32, and create a new pool has only the pool member FTP1 defined.

  B. Add FTP1 to the pool assigned to the MyVS4 virtual server, and remove all other pool members from the pool.

  C. Create a new virtual server for traffic sourced from 10.10.10.0/24 on traffic sourced from 10.10.10./24

  on port 21 that is destined to 10.10.20.1/32, and create a new pool that has only the pool member FTP1 defined.

  D. Add FTP1 to the pool assigned to the MyVS2 virtual server, and remove all other pool member from the pool.

  Correct Answer: D

  According to the VS matching order, first match the destination host IP, then match the destination port and finally match the source network segment. In the current network configuration, 10.10.10./24 access to

  10.10.10.20.1 will hit MyVS2.

  If there is no error in the title, subnet 10.10.10.0 to virtual

  Server 10.10.20.1 to the FTP1 server,'' Is to distribute all traffic from 10.10.10.1 to FTP1, then D That's

  right.
