A.Constraint-based LSPs must use RSVP-TE signaling.

B.Constraint-based LSPs are calculated using the head-end router's TED.

C.IGP-based LSPs must use LDP signaling.

D.IGP-based LSPs are calculated based on information contained in routing tables.

A.Layer 2 multipoint-to-multipoint service.

B.Layer 2 point-to-point service.

C.Layer 3 IP multipoint-to-multipoint VPN service.

D.Layer 3 direct Internet access service.

A.The IP destination address is used to initiate echo requests,

B.The test fails if the LSP is not operationally up.

C.An echo request is sent based on the LSP's label stack.

D.Echo reply packets may not take the same path as the LSP.

A.It tests the IGP reachability of the far-end IP address of an SDP.

B.It tests that the MTU settings of a service are correct.

C.It tests in-band, uni-directional or round-trip connectivity of SDPs.

D.It tests the reachability of hosts connected to an SDP.

A.RSVP-TE makes use of ordered control mode.

B.RSVP-TE is an MPLS signaling protocol, based on the resource reservation protocol.

C.RSVP-TE enables the establishment of explicitly routed LSPs that can be automatically routed away from network failures

D.RSVP-TE operates in a downstream unsolicited label advertisement mode.

E.RSVP-TE supports explicitly routed LSPs using either loose or strict route definitions.
