Which three statements about MPLS traffic engineering (MPLS TE) are true? (Choose three)

The correct answer is A. MPLS TE supports admission control D. MPLS TE provides protection capability E. MPLS TE uses RSVP to establish LSP. A is TRUE: MPLS TE uses RSVP-TE for admission control, allowing the network to accept or reject tunnel requests based on available bandwidth. D is TRUE: MPLS TE supports Fast Reroute (FRR) for link and node protection, providing sub-50ms failover. E is TRUE: RSVP-TE (Resource…

Explanation

A is TRUE: MPLS TE uses RSVP-TE for admission control, allowing the network to accept or reject tunnel requests based on available bandwidth. D is TRUE: MPLS TE supports Fast Reroute (FRR) for link and node protection, providing sub-50ms failover. E is TRUE: RSVP-TE (Resource Reservation Protocol - Traffic Engineering) is the signaling protocol used to establish and maintain TE LSPs. B is FALSE: tunnel traffic volume is not itself a link attribute; bandwidth reservation is the link attribute used in path computation. C is FALSE: MPLS TE uses IGP extensions (OSPF-TE or IS-IS-TE) to flood link attributes (bandwidth, affinity) throughout the network - not BGP.
