Question: 21
Which two statements are true about VPLS? (Choose two.)
A. It can work over any transport that can forward IP packets.
B. It provides integrated mechanisms to maintain First Hop Resiliency Protocols such as HSRP, VRRP, or GLBP.
C. It includes automatic detection of multihoming.
D. It relies on flooding to propagate MAC address reachability information.
E. It can carry a single VLAN per VPLS instance.
Answer: DE
Explanation:
VPLS relies on flooding to propagate MAC address reachability information. Therefore, flooding cannot be prevented. VPLS can carry a single VLAN per VPLS instance. To multiplex multiple VLANs on a single instance, VPLS uses IEEE QinQ.
