Question 1

Assuming TLDP and RSVP are both being used in an MPLS network core which of the following statements is true?

ATLDP is used to create the inner label, RSVP is used to create the outer label.

BTLDP is used to create the outer label, RSVP is used to create the inner label.

CTLDP and RSVP cannot be used in the same network since they both provide the same label.

DWhen RSVP is used, TLDP must be disabled and static vc labels should be used.

ETLDP and RSVP can be used to create either labels based on how they are configured.

Answer : A

Question 2

Multiple VPLS services can be offered over the same set of LSP tunnels?

ATRUE

BFALSE

Answer : A

Question 3

What are the benefits of a hierarchical VPLS architecture? (Choose 3)

AIncreases scalability

BReduces the FDB size within a VPLS instance

CReduces replication and bandwidth utilization from the MDU device to the core network

DEasier to manage

EReduces the routing table size

Answer : A, C, D

Question 4

Click on the exhibit below.

You have been requested to add load balancing across the redundant spoke-SDPs in the network shown. What further configuration is required? (Choose 2)

AAn additional management VPLS.

BAnother set of LSPs between PE1 and PE3 and between PE2 and PE4.

CAnother set of SDPs between PE1 and PE3 and between PE2 and PE4.

DLoad balancing has to be enabled within the management VPLS.

Answer : A, C

Question 5

Click on the exhibit below.

The following VPLS services and SAPs have been configured. Which of the following statements is true?

AAll untagged frames will be dropped.

BThe source MAC address of a frame with a top tag of 200 and bottom tag of 300 will be populated in VPLS 3.

CAll frames with more than one tag will be dropped.

DThe source MAC address of a frame with a single tag of 500 will be populated in VPLS 1.

EThe source MAC address of a frame with a top tag of 100 will be populated in VPLS 2.

Answer : E

Question 6

Click on the exhibit below.

Assume there are two VPLS services configured on the MDU. How could load-balancing be achieved when using Active/Standby pseudowires?

AThis cannot be done.

BEach VPLS will use the same pair of SDP's with the same endpoint configured with the option 'load-balancing 2'.

CEach VPLS will need their own pair of spoke-SDP's configured. The spoke-sdp's that are to be active should be configured with the option 'precedence primary'.

DUnder the end-point configuration, enable load-balancing 2 and the MDU will load balance automatically.

Answer : C

Question 7

Fill in the blank for this next sentence. Flooded traffic received on any ____________ in the service is replicated to other spoke SDPs and SAPs and not transmitted on any mesh SDPs.

ASpoke SDP

BMesh SDP

CEither (a) or (b) will make this sentence true.

DNeither (a) nor (b) will make this sentence true.
