質問 5:An active/standby pair of LTM devices deployed with network failover are working as desired. After external personnel perform maintenance on the network, the LTM devices are active/active rather than active/standby. No changes were made on the LTM devices during the network maintenance.
Which two actions would help determine the cause of the malfunction? (Choose two.)
A. checking synchronization of system clocks among the network devices
B. checking the configuration of the VLAN used for mirroring
C. checking the open ports in firewalls between the LTM devices
D. checking that the configurations are synchronized
