Which of the following describes the setting of the l-SID on the Nokia 7750 SR?

A.

The I-SID is set to 0 by default and is only used for interop purposes. The receiving PE uses the service label to determine the I-VPLS.

B.

There is no default value. The I-SID must always be explicitly configured

C.

The I-SID is set to the service-id, unless the service-id is larger than a 24 bit value. In this case the I-SID must be explicitly configured.

D.

The I-SID is always set to the service-id by default.

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

A.

TRUE

B.

FALSE

How is it possible for multiple services to be carried over the same MPLS LSPs?

A.

Multiple SDPs must be configured and bound to the LSPs for this to be possible.

B.

It is not possible to carry multiple services over the same MPLS LSPs.

C.

A vc-label is signaled per service.

D.

The vc-id is part of the data plane and maps the traffic to the appropriate service.

Which of the following describes the overhead added to a customer frame on an Ethernet link in a VPLS service on the Nokia 7750 SR?

A.

The overhead consists of 26 bytes. 14 DLC + 2 Ethertype + 8 for mpls labels + 2 for GRE

B.

The overhead consists of 14 bytes for DLC.

C.

The overhead consists of 18 bytes. 14 DLC +4 for mpls labels

D.

The overhead consists of 22 bytes. 14 DLC + 8 for mpls labels

Assuming there is a full mesh of mesh-SDPs between the PEs within each metro network and a spoke-SDP between PE-C of Metro A and PE-B of Metro B. how is traffic forwarded from PE-A in Metro A to PE-D of Metro B? Select the most accurate statement.

A.

An LSP must be configured between PE-A and PE-D for this traffic to be forwarded.

B.

A VPLS FDB lookup is done at PE-A of Metro A only

C.

An SDP must be configured between PE-A of Metro A and PE-D of Metro D for this traffic to be forwarded

D.

A VPLS FDB lookup is done at PE-A and PE-C of Metro A and PE-B of Metro B

Which of the following are required for an operational mesh-sdp binding for bidirectional traffic when signaling is enabled within the SDP? (Choose 3)

A.

LDP must be enabled.

B.

RSVP must be enabled.

C.

An SDP must be configured on the far-end.

D.

Service MTU must match.

E.

SDP ID must match.

Which of the following best describes the difference between VPWS and VPLS?

A.

Unlike VPLS. VPWS appears as a multi-hop network to the customers.

B.

Unlike VPLS, VPWS allows CEs that are member of the same service instance to communicate with each other as if they are connected via a bridged LAN.

C.

Unlike VPWS, VPLS allows customers to view the network as a routed network.

D.

Unlike VPWS, VPLS is a service where customer MAC addresses are learned.

An l-VPLS is configured with a service id of 511. What will the value of the l-SID be assuming a default configuration?

A.

The 1-SID must be explicitly configured.

B.

The 1-SID only supports a range from 1 to 255.

C.

The 1-SID will default to 511 .the value of the service-id.

D.

Thel"SIDwilldefaultto131582, the value of the service-id + 131071.

An l-VPLS can be associated with many B-VPLS services.

A.

TRUE

B.

FALSE
