Assume the port on CE-A is sending two tags, a top tag of 100 and a bottom tag of 500. PE-A is configured with a SAP id of 1/1/1:100.*. How should PE-B be configured if CE-B is expecting a top tag of 200 and a bottom tag of 500?

A.PE-B will require a SAP id of "sap 1/1/1:500.200".
B.PE-B will require a SAP id of "sap 1/1/1:200*".
C.PE-B will require a SAP id of "sap 1/1/1:500*".
D.PE-B will require a SAP id of "sap 1/1/1:100*".

Which SDP on R3 will MAC addresses be associated with for devices behind R2?

A.Devices behind R2 will be associated with the sdp between R3 and R4.
B.It depends if traffic is received via R4 or R1 from devices behind R2.
C.Devices behind R2 will be associated with the sdp between R3 and R1.
D.The devices cannot communicate based on the configuration in the diagram so there will be no mac address association.

What needs to be configured in a VPLS in order to forward customer STP BPDUs transparently?

Question 4

If the max remote-age timer of a B-VPLS is reached, what happens to the remotely learned MAC addresses in the l-VPLS service?

A.By default, the remote-age timer of the B-VPLS is configured to 0 and addresses do not age out. The l-VPLS uses its own timer.
B.There is no effect. The MAC addresses for the l-VPLS age out independently of the aging of B-VPLS addresses.
C.The MAC addresses for the l-VPLS will age out immediately following the remote-age out of the backbone-macs of the B-VPLS.
D.The same timer is used for B-VPLS and l-VPLS addresses on the node.

Question 5

How do user VPLSs become associated with a management VPLS for redundant spokesdp connections?

A.The association must be defined in the user VPLS service.
B.The association is based on service IDs.
C.The association is done when the user VPLS is associated with the same sdp-id in the management VPLS
D.The association is based on customer IDs.
