JNCIP-ENT: Juniper Networks Certified Professional – Enterprise Routing (2024) — Question 34

You must ensure that all routes in the 10.0.0/8 address range are not advertised outside of your AS.
Which well-known BGP community should be assigned to these addresses to accomplish this task?

Answer options

• A. no-export
• B. no-peer
• C. internet
• D. no-advertise

Correct answer: A

Explanation

The correct answer is 'no-export' because this well-known BGP community prevents routes from being advertised to external Autonomous Systems. The 'no-peer' option is not a valid BGP community, 'internet' indicates that the route can be advertised to the internet, and 'no-advertise' prevents the route from being advertised to any peer, not just outside the AS.
