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.)

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.

D.
Verify that ConfigSync is using the management IP address.

E.
Verify that port lockdown on the ConfigSync interface is set to allow port 1026.
