Question # 33

In the diagram below, SAP 1 is put into the blocking state as a result of the spanning tree protocol. What will occur in the VPLS instance if SAP 2 goes down and SAP 1 transitions to the forwarding state? Select the most accurate statement.

Options:

A.  

A Spanning Tree BPDU will be sent across the mesh flushing the FDB table in all devices participating in the VPLS instance.

B.  

Stale information will be used within the VPLS instance to forward traffic until the FDB ages out.

C.  

An LDP control message will be sent to all devices in the mesh participating in the VPLS instance. Only MAC addresses associated with the PE that the failure occurred on will be flushed.

D.  

An LDP control message will be sent to all devices in the mesh participating in the VPLS instance. The entire FDB in the VPLS instance will be flushed.

Options:

A.  

sap 1/1/1:200.100

B.  

sap 1/1/1:200*

C.  

sap 1/1/1:*

D.  

sap 1/1/1:0*

Question # 37

What function in IEEE 802.1 ah helps to limit the amount of MAC addresses learned in the core?

Options:

A.  

I-VPLS is configured in the core of the network with an l-MAC address. This l-MAC address is the only MAC learned in the core

B.  

The B-VPLS and l-VPLS are configured in the edge. The B-VPLS is configured with a Backbone MAC and is the only MAC learned in the core

C.  

Each SDP is configured with a Backbone MAC to hide customer MAC addresses in the core

D.  

Each SAP is associated with a common l-MAC to hide customer MAC addresses in the core

oam mac-trace

D.  

oam svc-ping

Question # 39

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?

Options:

A.  

Bandwidth and replication inefficiency can occur on inter-metro links if there is a lot of multicast traffic

B.  

The number of control sessions grows exponentially in a fully meshed network.

C.  

Spanning-tree is required to prevent loops when using mesh SDPs on the inter-metro links.

D.  

Network touches increase with each node added to the mesh.

B.  

Can be used in ring networks of 4 or more nodes
