单选题 What should a BIG-IP Administrator configure to minimize impact during a failover?

A、 MAC masquerading
B、 External monitors
C、 OneConnect profile
D、 Clone pool

单选题 The BIG-IP Administrator wants to provide quick failover between the F5 LTM devices that are configured as an HA pair with a single-selfip using the MAC Masquerade feature for this quick failover and runs this command: tmsh modify /cm traffic-group traffic-group-1 mac 02:12:34:56:00:00 However, the Network Operations team has identified an issue with the use of the same MAC address being used within different VLANs. As a result, the administrator decides to implement the Per- VLAN Mae Masquerade in order to have a unique MAC address on each VLAN: tmsh modify /sys db tm.macmasqaddr_per_vlan value true. What would be the resulting MAC address on a tagged VLAN of 1501? (Choose one answer)

A、 02:12:34:56:01:15
B、 02:12:34:56:dd:05
C、 02:12:34:56:05:dd
D、 02:12:34:56:15:01
