A data center network uses BGP to advertise a prefix to an upstream provider. The network administrator wants to ensure that the upstream provider does not advertise this prefix to its own upstream providers, effectively keeping the prefix local to the data center. Which BGP attribute should be used?

Set the MED attribute on the route advertised to the upstream provider.

Set the LOCAL_PREF attribute on the route advertised to the upstream provider.

Set the NO_EXPORT community on the route advertised to the upstream provider.

Set the AS_PATH attribute to prepend the local AS number multiple times.

What mechanism does BGP use to maintain a peering session and detect failures?

Hello packets sent every 10 seconds

Keepalive messages sent periodically

How does BGP advertise a route to a peer?

By sending a full routing table update every 30 seconds

By sending an UPDATE message containing the network prefix and path attributes

By sending a broadcast packet to all routers on the subnet

By sending a Link-State Advertisement to all routers in the area

In a data center underlay using eBGP, what is a common practice to simplify configuration and scaling?

Assigning a unique private AS number to each leaf and spine switch

Using a single autonomous system number for all switches

Using BGP confederations to divide the fabric into sub-ASes

Disabling BGP timers to reduce overhead
