Refer to the exhibit. P3 and PE4 are at the edge of the service provider core and serve as ABR routers.
Aggregation areas are on either side of the core.
Which statement about the architecture is true?

• A.To support seamless MPLS, the BGP route reflector feature must be disabled.
• B.If each area is running its own IGP, BGP must provide an end-to-end MPLS LSP.
• C.If each area is running its own IGP, the ABR routers must redistribute the IGP routing table into BGP.
• D.To support seamless MPLS, TDP must be used as the label protocol.

What is the difference between SNMP and model-driven telemetry?

• A.SNMP uses the YANG data modeling language
• B.Telemetry allows for modeled network data to be pushed to the network administrator on an as-needed basis
• C.SNMP pushes network data to the network administrator whenever it is queried
• D.Telemetry uses traps and inform messages to deliver data to a network administrator on a polling basis

Drag and drop the functions from the left onto the correct Path Computation Element Protocol roles on the right

Correct Answer:

Explanation

Path Computation Element (PCE)
Represents a software module (which can be a component or application) that enables the router to compute paths applying a set of constraints between any pair of nodes within the router's TE topology database. PCEs are discovered through IGP.
Path Computation Client (PCC)
Represents a software module running on a router that is capable of sending and receiving path computation requests and responses to and from PCEs. The PCC is typically an LSR (Label Switching Router).
