• Question 331:

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

• Question 332:

  An LTM Specialist needs to create an iRule that creates persistence records based on a JSESSIONID cookie. If a persistence record already exists, then the iRule must persist the client connection according to the existing record. Which persistence profile enables the iRule to meet these requirements?

  A. Universal
  B. SSL
  C. Destination Address Affinity
  D. Cookie
  E. Source Address Affinity
  A. Universal

• Question 333:

  Refer to the exhibit.

  

  How many nodes are represented on the network map shown?

  A. Four
  B. Three
  C. One
  D. Two
  B. Three

• Question 334:

  An LTM Specialist needs to apply SNAT using currently used SNAT pool to a new virtual server. What needs to be completed before applying that configuration change?

  A. Review connection for the selected SNAT pool and enlarge it if appropriate
  B. Make sure that the BIG-IP device is NOT operating under heavy load during peak times
  C. Verify that the IP address of the SNAT pool are in the same subnetas the pool members
  D. Verify that the IP address of the SNAT pool are in the same VLAN as the pool members.
  A. Review connection for the selected SNAT pool and enlarge it if appropriate

• Question 335:

  Refer to the exhibit.

  

  An LTM Specialist is troubleshooting a virtual server. Both the virtual server and the pool are showing blue squares for their statuses, and new clients report receiving "The connection was reset" through their browsers. Connections directly to the pool member are successful.

  What is the issue?

  A. The pool member is disabled.
  B. The node is marked as disabled.
  C. The HTTP profile has incorrect settings.
  D. The virtual server is disabled on all VLANs.
  B. The node is marked as disabled.

• Question 336:

  A virtual server offloads SSL from backend servers using a clientssl profile and a custom serverssl profile.

  Users report that large file uploads (>50 MB) fail intermittently.

  Which setting should the Administrator review first?

  A. Proxy Buffer High and Proxy Buffer Low in the TCP profile
  B. Renegotiation Period in the clientssl profile
  C. Unclean Shutdown in the serverssl profile
  D. OneConnect Source Mask configuration
  A. Proxy Buffer High and Proxy Buffer Low in the TCP profile

• Question 337:

  An application is sensitive to packet loss and unexpected session termination. A pair of LTM devices is configured in an Active/Standby high availability configuration. SNATS are NOT used and the virtual server contains a Universal Persistence profile.

  Which two actions must an LTM Specialist take to ensure the sessions are maintained between the client and server during an LTM device failover event while maintaining maximum uptime? (Choose two.)

  A. configure a serial failover cable for mirror traffic
  B. configure a OneConnect profile to mirror connections
  C. configure a VLAN and primary mirroring address for mirror traffic
  D. enable Mirroring for a virtual server and persistence profile
  E. enable Clone Pools for a virtual server and a persistence profile
  C. configure a VLAN and primary mirroring address for mirror traffic
  D. enable Mirroring for a virtual server and persistence profile

• Question 338:

  C. The Virtual Server is disabled.
  D. All pool members have been disabled.
  A. All pool members are down.
