Question #2

On an Alcatel-Lucent 7750 SR, the OAM command 'svc-ping' can be used with options bcal-sdp' and 'remote-sdp'. Which of the following is TRUE?

A. Both 'Iocal-sdp' and 'remote-sdp' take parameters to specify which SDPs are used for the test.

B. 'Iocal-sdp' indicates that the ping is sent in-band, and remote-sdp' indicates the return ping is in-band.

C. iocal-sdp' and 'remote-sdp' indicate that all services using these SDPs are pinged.

D. 'Iocal-sdp' and remote-sdp' indicate that pings are initiated from both local and remote routers.

Question #4

Click on the exhibit button below.

Is a routing policy required on PE1 to advertise a CE1's system interface to PE2?

A. A CE1 system interface can not be advertised to PE2 since the CE routers are not aware of the VPRN.

B. A routing policy is required only when BGP is used as the PE-CE routing protocol, as shown in the exhibit.

C. Yes. A routing policy is required to advertise routes between PE routers in a VPRN

D. No. A routing policy is not required; the default behavior on the 7750 SR is to advertise all VPRN routes between PE routers.

Question #5

Which of the following statements best describes the main difference between an Ipipe and
an Epipe interworking?

A. An Ipipe is used for performing Ethernet interworking with ATM/FR/PPP using bridged-PDUs. An Epipe interworking is used for performing Ethernet interworking with ATM/FR/PPP using routed-PDUs.

B. An Ipipe is a point-to-point Layer 2 VPN capable of only carrying Ethernet payloads. An Epipe interworking refers to the transportation of ATM/FR traffic over an Epipe.

C. None of the above.

D. An Ipipe is used for performing Ethernet interworking with ATM/FR/PPP using routed-PDUs. An Epipe interworking is used for performing Ethernet interworking with ATM/FR/PPP using bridged-PDUs.

B. Set the SDP MTU of the IES to match the SDP MTU of the VPLS.

C. Set the service MTU of the VPLS to match the IES MTU.

D. Set the MTU of the IES's network port to match the service MTU of the VPLS.
