  Which command sill correct the issue?

  A. {/Common)(tmos) # modify /syssyslog remote-servers modify (syslog_dest2 {local-ip

  B. {/Common)(tmos) # modify Ays syslog remote servers modify {syslog_dest2 {local- ip 10.208.102 254)}

• Question 78:

  Exhibit.

  

  The LTM devices LTM1 and LTM2 are configured in a Device Group (Sync Failover) with Network Failover configured on both the management and HA and Internal VLANS. and ConfigSync is confined in a Device Group (Sync Failover) with Network Failover and internal are tagged on a single trunk with subnets Connection Mirroring is configured on both the HA interlace directly connected between LTM1 and LTM2, and the management interlace is connected to a management switch. The LTM devices have four Traffic Groups defined, and both LTM devices are healthy and capable of passing traffic for any of the Traffic Groups. An LTM Specialist disconnects the cable for the HA network in an effort to test failover. Which HA functionality works in this case?

  A. ConfigSync does NOT work. Connection Mirroring floes NOT work.

  B. ConfigSync works Connection Mirroring works

  C. ConfigSync works. Connection Mirroring docs NOT work

  D. ConfigSync does NOT work; Connection Mirroring works

  Correct Answer: D

• Question 79:

  A web server's default gateway is the network router. The LTM Specialist needs to introduce an LTM device to load balance to the web servers without changing the server's default gateway. Which deployment method and settings should the LTM Specialist use to ensure correct traffic flow and that the web servers can obtain the actual con IP addresses?

  A. route deployment with Automap configured and X-Forwarded-For inserted in HTTP headers

  B. route deployment without SNAT configuration

  C. SNAT deployment with automap configured and X-Forwarded-For inserted in HTTP headers

  D. SNAT deployment with automap configured

  Correct Answer: C

• Question 80:

  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

  Correct Answer: CD
