A route is received from an EBGP peer and has a LOCAL_PREF of 150 set locally. The route also carries a COMMUNITY attribute of 65000:100. When this route is advertised to an EBGP peer, which attributes will be included in the update?

COMMUNITY is included, but LOCAL_PREF is stripped.

LOCAL_PREF is included, but COMMUNITY is stripped.

LOCAL_PREF and COMMUNITY are both included.

Neither LOCAL_PREF nor COMMUNITY is included.

A route is received from an EBGP peer and has an AS_PATH that includes a confederation AS. The route also has the ATOMIC_AGGREGATE attribute set. What does the presence of ATOMIC_AGGREGATE indicate about this route?

The route has been filtered and is not valid.

The route is from a confederation and will be treated as internal.

The route is the best path and will be preferred over others.

The route is an aggregate that may have lost some path information.

What information does the AGGREGATOR attribute carry in BGP?

The next hop IP address for the aggregated route

The AS number and router ID of the router that performed route aggregation

The list of communities associated with the aggregated route

The origin of the aggregated route

What is the purpose of the ATOMIC_AGGREGATE attribute in BGP?

To carry a list of communities for filtering

To specify the next hop for aggregated routes

To influence inbound traffic by setting a lower metric

To indicate that a less specific route has been aggregated and some path information may be missing

A BGP router has two paths to the same destination. Path 1 has a LOCAL_PREF of 150 and an AS_PATH length of 3. Path 2 has a LOCAL_PREF of 120 and an AS_PATH length of 2. Which path will be selected as the best path?

Path 2, because AS_PATH length is compared before LOCAL_PREF.

Path 2, because LOCAL_PREF is higher.

Path 1, because LOCAL_PREF is compared before AS_PATH length.

Path 1, because AS_PATH length is shorter.
