Implementing and Operating Cisco Service Provider Network Core Technologies (SPCOR) — Question 144

What are two factors to consider when implementing NSR High Availability on an MPLS PE router? (Choose two.)

Answer options

• A. It requires all PE-CE sessions to support NSR
• B. It requires routing protocol extensions
• C. It consumes more memory and CPU resources than NSF
• D. It operates normally without NSR support on the PE peers
• E. It cannot sync state information across redundant RPs

Correct answer: C, D

Explanation

The correct answers are C and D because NSR High Availability does indeed utilize more memory and CPU resources than NSF, which is a key consideration. Additionally, NSR can operate without requiring NSR support on PE peers, making D correct. The other options either incorrectly state requirements or capabilities of NSR, thus they are not valid considerations.
