Question 65

Click the Exhibit button.

Referring to the exhibit, what do the brackets [ ] in the AS path identify?

They identify that the autonomous system number is incomplete and awaiting more information from the BGP protocol.

They identify that a BGP confederation is being used to ensure that there are no routing loops.

They identify an AS set. which are groups of AS numbers in which the order does not matter.

They identify the local AS number associated with the AS path if configured on the router, or if AS path prepending is configured.

Correct Answer: D

In the context of the exhibit, the brackets [ ] around the AS path identify that it is the local AS number associated with the AS path, if configured on the router, or in case AS path prepending is configured. In BGP (Border Gateway Protocol) terminology, brackets are typically used to denote local AS numbers or summarization of AS paths. Options suggesting an incomplete AS number, a BGP confederation, or an AS set do not correctly explain the usage of brackets in this scenario.
