Question 1 of 30
In a service provider network, a network engineer is tasked with implementing BGP communities to manage routing policies effectively. The engineer decides to use a community string to tag routes originating from different geographical regions. The community string for routes from the East region is set to 100:1, while the West region is tagged with 100:2. If the engineer wants to apply a policy that allows only routes from the East region to be advertised to a specific peer, which of the following configurations would achieve this goal?
Set the route map to permit only community 100:1 and apply it to the outbound policy for the peer.
Configure the peer to accept all routes and filter out community 100:2.
Use a prefix list to match only the prefixes from the East region and apply it to the peer.
Implement a route policy that denies all communities except 100:2.
