Implementing and Operating Cisco Service Provider Network Core Technologies (SPCOR) — Question 328

What must a network engineer consider when designing a Cisco MPLS TE solution with OSPF?

Answer options

• A. The OSPF extensions and RSVP-TE must be enabled on all routers in the network.
• B. OSPF extensions for RSVP-TE are supported in Area 1.
• C. The OSPF extensions and RSVP-TE must be enabled on the egress routers.
• D. OSPF extensions for RSVP-TE are implemented in Type 6, 7, and 8 LSAs.

Correct answer: A

Explanation

The correct option A is valid because all routers in the network must have OSPF extensions and RSVP-TE enabled to ensure proper functionality of the MPLS Traffic Engineering. Options B and C are incorrect as they limit the scope to only certain areas or routers, while option D incorrectly identifies the type of LSAs associated with OSPF extensions for RSVP-TE.
