BIG-IP Local Traffic Manager (LTM) Specialist: Maintain & Troubleshoot (Page 7 )

Updated On: 1-Feb-2026

A device group is made up of four members: LTM-A, LTM-B, LTM-C, and LTM-D. An LTM Specialist makes a configuration change on LTM-B. Later, a different LTM Specialist notices a "changes pending" message on all devices. When logged into LTM-D, the LTM Specialist attempts to config-sync to the device group. The sync operation fails.
Why is the LTM Specialist on LTM-D unable to synchronize the configuration to the group?

  1. The changes made on LTM-B are invalid.
  2. LTM-D has the lowest commit-id of the group.
  3. NTP is NOT configured on the devices in the group.
  4. LTM-B is the device eligible to initiate a config-sync.

Answer(s): D



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.
Which two steps should the LTM Specialist take to identify the issue? (Choose two.)

  1. Verify that NTP is synchronized.
  2. Verify the network connectivity between the devices.
  3. Verify that the devices are not using self-signed certificates.
  4. Verify that ConfigSync is using the management IP address.
  5. Verify that port lockdown on the ConfigSync interface is set to allow port 1026.
