Which of the following best describes the flooding of traffic on a PE when unknown traffic is received on a SAP of a VPLS? A technician sitting in a Network Operations Center would like to set up a remote mirror on an Alcatel-Lucent 7750 Service Router to examine some data traffic ingressing a port at a remote site. Which of the following are required? (Choose 2) Which of the following encapsulation types on an Ethernet port support the provisioning of multiple SAPs? (Choose 2) How many service labels must be signaled to bring up a fully-meshed VPLS among five PE routers?

Which of the following about transport and service tunnels is FALSE? Which of the following statements are TRUE regarding sdp-ping? (Choose 3) Which of the following SAPs can be used so that only untagged frames and frames with a VLAN tag of 0 are accepted? 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? On the Alcatel-Lucent 7750 SR, which of the following statements about MP-BGP used for a VPRN is TRUE? VPWS allows carriers to offer services such as point-to-point frame-relay, ATM, and Ethernet on a single platform without the need for multiple overlay networks. Which of the following commands is used in an RSVP signaled MPLS tunnel to validate the path MTU based on signaling across the LSP? What is a key benefit of a VPLS service? An IPv4 MPLS provider network is being configured for 6VPE. BGP is being used for the PE- CE protocol to exchange IPv6 routes. Which of the following is FALSE? A transport tunnel can either use an MPLS or GRE encapsulation.
