If the SDP between R2 and R1 goes down, what devices will be reachable from R2 through the VPLS?

• A.R4 and R3 will remain reachable.
• B.No devices will be reachable.
• C.Only R4 will be reachable through the VPLS. B All devices will be reachable through the VPLS.

What is the MTU impact on the SDP path-mtu if fast reroute, one-to-one mode is implemented on the LSP?

• A.The path-mtu will increase by 8 bytes.
• B.There will be no impact on the path-mtu.
• C.The path-mtu will decrease by4 bytes.
• D.The path-mtu will decrease by 8 bytes.
• E.The path-mtu will increase by 4 bytes.

Which of the following describes the scope of the IEEE 802.3ah EFM standard? (Choose 3)

• A.Should not be used at the core to trigger MPLS protection. BFD is the only method that can be used when physical failure detection is not possible.
• B.Can be used at the core to trigger MPLS protection mechanisms when a physical failure detection is not possible.
• C.Monitor and troubleshoot end-to-end services.
• D.Monitor and troubleshoot a point-to-point full-duplex link.
• E.Valuable in the last-mile connection to the Service Provider demarcation device.

Which SDP on R3 will MAC addresses be associated with for devices behind R2?

• A.Devices behind R2 will be associated with the sdp between R3 and R4.
• B.Devices behind R2 will be associated with the sdp between R3 and R1.
• C.It depends if traffic is received via R4 or R1 from devices behind R2.
• D.The devices cannot communicate based on the configuration in the diagram so there will be no mac address association.
