Implementing and Operating Cisco Service Provider Network Core Technologies (SPCOR) — Question 25

A customer of an ISP requests support to setup a BGP routing policy. Which BGP attribute should be configured to choose specific BGP speakers as preferred points for the customer AS?

Answer options

• A. lowest multi-exit discriminator
• B. highest local preference outbound
• C. lowest local preference inbound
• D. highest local preference inbound

Correct answer: D

Explanation

The correct answer is D because the highest local preference inbound attribute is used to indicate the preferred exit point from the AS for outbound traffic. The other options do not effectively prioritize BGP speakers for this purpose, with A focusing on exit points based on the lowest MED, which is not applicable here, and B and C not directly influencing the inbound preference.
