QUESTION: 41

What are the advantages of running a physical ring topology with a mesh of mesh-SDPs? (Choose 2)

STP can be used to break the loop.
STP is not required to break the loop because of split-horizon rules.
If the traffic is primarily multicast, a full mesh of SDPs is a simple and efficient design.
If the traffic is primarily Unicast, a full mesh of SDPs is a simple and efficient design.

Answer(s): B,D

QUESTION: 42

Consider a large metro-to-metro VPLS network interconnected with a mesh of mesh-SDPs. Which of the following statements does NOT apply to this situation?

Bandwidth and replication inefficiency can occur on inter-metro links if there is a lot of multicast traffic
The number of control sessions grows exponentially in a fully meshed network.
Spanning-tree is required to prevent loops when using mesh SDPs on the inter-metro links.
Network touches increase with each node added to the mesh.

QUESTION: 44

Redundant spoke-SDPs are used between 2 Metro networks for redundancy. How can load balancing be achieved across the redundant spoke-SDPs?

A single management VPLS using RSTP can be used to block different SDPs for different VPLS services.
A single management VPLS using 802.1D-2004 can be used to block different SDPs for different VPLS services
There is no way to have load balancing across redundant spoke-SDPs.
Two management VPLS using RSTP can be used to block different SDPs for different VPLS services.
