BIG-IP Administration Data Plane Concepts (F5CAB2) (F5CAB2) Free Practice Test

Question 1

The BIG-IP Administrator wants to provide quick failover between the F5 LTM devices that are configured in an HA Pair with a single traffic-group. The BIG-IP Administrator wants to implement the Mac Masquerade feature for this quick failover and run 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 of this, the BIG-IP Administrator must implement the Per-VLAN Mac 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?

A. 02:12:34:56:01:15

B. 02:12:34:56:05:dd

C. 02:12:34:56:15:01
