In a traditional (non EVPN) VPRN service, which of the following statements about Route Target (RT) is FALSE?
AAn RT is used to indicate the VPN service to which a route update is relevant.
BAn RT value is assigned to each VPRN service.
CAn RT is included as an extended community in MB-BGP route updates.
DConfiguring different RT values allows VPN customers to use the same private IP prefixes.
This output is from router R4. Service 333 is a VPLS. Why might the peer 10.10.10.1 have the same value for IngLbl and EgrLbl?
AThe labels are of local significance only, so other routers can use the same value.
B10.10.10.1 has yet to send its own unique label.
CRouter R4 is using the same tunnel to send and receive to 10.10.10.1.
DThe service on 10.10.10.1 is down, so it is rejecting packets.
Which of the following statements about the components of a distributed service on the Nokia 7750 SR is TRUE?
AA SAP can only be used by one service on a router.
BA dedicated SDP needs to be created for each service.
CA service is created on each site before the customer is created.
DSAPs must be created before a service is created.
Which protocol is used to signal the inner label for a Layer 2 VPN service?
ARSVP
BIPCP
CTLDP
DPPP
EEither RSVP or LDP
Consider an E-pipe service configured with SAP 1/1/1:5 and SAP 1/1/1:6.7. If the SAP 1/1/1:5 accepts an ingress frame, which of the following statements is TRUE?
AThe frame egresses 1/1/1:6.7 with an outer VLAN tag of 6 and inner tag of 7.
BThe frame is dropped at the egress SAP 1/1/1:6.7.
CThe frame egresses 1/1/1:6.7 with VLAN tag 5.
DThe frame egresses 1/1/1:6.7 with VLAN tag 6
Which of the following statements about IS-IS Traffic Engineering on a Nokia 7750 SR is FALSE?
ATraffic engineering information is carried in the extended TLVs.
BTraffic engineering must be enabled on all IP/MPLS routers along the LSP path.
CTraffic engineering information is stored in the opaque database.
DTraffic engineering is required for constraint-based LSPs
Which of the following statements about RSVP-TE summary refresh messages is TRUE?
AThey list the RSVP session names that the router is refreshing.
BThey list the Message IDs that the router is refreshing.
CThey list the Tunnel IDs that the router is refreshing.
DThey list the LSP IDs that the router is refreshing.
An E-pipe is configured with a service MTU of 5000. What value will be derived for the VC-MTU?

Assuming CE1 exports its system address using BGP, is a routing policy required on PE1 to advertise CE1's system address to PE2?
AYes. A routing policy is required to advertise routes between PE routers in a VPRN regardless of the CE-PE routing.
BYes. A routing policy is required in this case because BGP is used as the PE-CE routing protocol.
CNo, a routing policy is not required. By default, the Nokia 7750 SR will advertise all VPRN routes between PE routers.
DNo, a routing policy is not required on PEI, but an import policy is required on PE2.
On a Nokia 7750 SR, the OAM command 'svc-ping' can be used with options 'local-sdp' and 'remote-sdp'. Which of the following statements is TRUE?
A'local-sdp' and 'remote-sdp' indicate that all services using these SDPs are pinged.
B'local-sdp' and 'remote-sdp' indicate that pings are initiated from both local and remote routers.
CBoth 'local-sdp' and 'remote-sdp' take parameters to specify which SDPs are used for the test.
D'local-sdp' indicates that the ping is sent in-band, and 'remote-sdp' indicates the return ping is in-band.
LSP1 is an LDP based LSP going from PE1 to PE3 through PE2 (see diagram). All links cost are shown in the diagram. LDP FRR is configured. If the link between PE2 and PE3 goes down, what is the likely path for LSP1 shortly after the failure?

BThe outer label TTL will be 249 and the inner label TTL will be 251.
CThe outer label TTL will be 251 and the inner label TTL will be 251.
