When spanning tree is enabled within a VPLS service and the STP mode is 802.1 D 2004 what happens if a PVST BPDU is received on a SAP?

ASpanning tree will be disabled on the SAP that the PVST BPDU was received on.

BThe SAP that the PVST BPDU was received on will be disabled to prevent loops.

CThe spanning tree encapsulation will be dynamically changed to PVST on the SAP the PVST BPDU was received on.

DThe PVST BPDU will be ignored and 802.1D 2004 BPDUs will continue to be transmitted on the SAP.

Answer : C

Question 2

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

AA single management VPLS using RSTP can be used to block different SDPs for different VPLS services.

BA single management VPLS using 802.1D-2004 can be used to block different SDPs for different VPLS services

CThere is no way to have load balancing across redundant spoke-SDPs.

DTwo management VPLS using RSTP can be used to block different SDPs for different VPLS services.

Answer : D

Question 5

How do user VPLSs become associated with a management VPLS for redundant spoke-sdp connections?

AThe association must be defined in the user VPLS service.

CThe association is based on service IDs.

DThe association is based on customer IDs.
