Exam 300-410 topic 1 question 302 discussion

B & E are correct

Control plane protocols are responsible for the operations and signaling within a network, including in an MPLS (Multiprotocol Label Switching) environment. The correct answers from the given options are: B. RSVP (Resource Reservation Protocol) E. LDP (Label Distribution Protocol) Explanation: RSVP: It's used for reserving resources and is also employed as a signaling protocol in MPLS Traffic Engineering (TE). LDP: This protocol is used for label distribution in MPLS, enabling routers to learn the labels to use for forwarding traffic. Option C (Targeted LDP) is a specialized use of LDP, so it's related but not a distinct protocol in this context. Options A (OAM - Operations, Administration, and Maintenance) and D (SNMP - Simple Network Management Protocol) are not typically classified as control plane protocols within the context of an MPLS network, as they are more related to management and monitoring.

Given anser is correct. There are two standardized protocols for managing MPLS paths: the Label Distribution Protocol (LDP) and RSVP-TE, an extension of the Resource Reservation Protocol (RSVP) for traffic engineering. Furthermore, there exist extensions of the Border Gateway Protocol (BGP) that can be used to manage an MPLS path.
