• Question 415:

  An LTM Specialist configures two LTM devices in a high-availability pair with trusts established and device groups configured properly using network failover. After several months, the LTM Specialist notices that changes made to one LTM device do NOT cause the synchronization status to update to "changes pending," and this device does NOT synchronize with the device group.

  A. Verify that NTP is synchronized.
  B. Verify the network connectivity between the devices.
  C. Verify that the devices are not using self-signed certificates.

  A. Verify that NTP is synchronized.
  B. Verify the network connectivity between the devices.

• Question 416:

  A. Connect via ssh to the AOM IP address.
  B. Connect via ssh to the management address.
  C. Connect to the LTM device via serial connection.
  D. Connect a monitor and keyboard to the LTM device.
  E. Connect via ssh to the standby unit and connect via ssh across the serial link between the devices.
  A. Connect via ssh to the AOM IP address.
  C. Connect to the LTM device via serial connection.

• Question 417:

  Active connections to pool members are unevenly distributed. The load balancing method is Least Connections (member) Priority Group Activation is disabled. What is a potential cause of the event distribution?

  A. Priority Group Activation is disabled
  B. SSL Profile Server is applied
  C. Persistence profile is applied
  D. incorrect load balancing method
  C. Persistence profile is applied

• Question 418:

  There are three servers in the pool: 172.16.20.1, 172.16.20.2, and 172.16.20.3, with the virtual IP address 10.0.20.88.

  A user CANNOT connect to an HTTP application. To understand the problem and find a solution, the LTM Specialist runs two concurrent traces on the LTM device, with the following results:

  Trace on client side:

  tcpdump: verbose output suppressed, use -v or -vv for full protocol decode

  listening on 0.0, link-type EN10MB (Ethernet), capture size 96 bytes
