What is the primary purpose of the BGP OPEN message during session establishment?

To negotiate session parameters and capabilities

To notify the peer of an error condition

To exchange routing prefixes and their attributes

To verify that the TCP connection is still active

How does a BGP peer group affect update generation for multiple peers?

It disables UPDATE messages for peers in the group

It generates a separate UPDATE message for each peer in the group

It requires each peer to have its own unique update policy

It allows the router to generate a single UPDATE message that is replicated to all peers in the group

In which scenario is the BGP synchronization rule typically disabled?

When the BGP session is established over a loopback interface

When the AS has multiple eBGP peers

When all routers in the AS are running BGP and have a full mesh of iBGP sessions

A network engineer is troubleshooting a BGP session that repeatedly flaps. The session reaches the Established state, but after exactly 90 seconds of inactivity, the session resets and the state returns to Idle. The engineer checks the configuration and sees that the hold timer is set to 90 seconds and the keepalive timer is set to 30 seconds. What is the most likely cause of this behavior?

The remote peer is not sending KEEPALIVE messages, so the local hold timer expires after 90 seconds and resets the session.

The hold timer is set to 90 seconds, which is below the minimum allowed value of 120 seconds for BGP.

The local router is sending KEEPALIVE messages every 30 seconds, but the remote peer has a hold timer of 60 seconds, causing a mismatch.

The keepalive timer is set too low, causing the peer to send updates too frequently and overwhelm the local router.

How does BGP withdraw a previously advertised route?

By sending a NOTIFICATION message with the route information

By sending an UPDATE message with the route in the withdrawn routes field

By sending a KEEPALIVE message with a special flag

By sending an OPEN message with a withdrawal indicator

Part of the Border Gateway Protocol (BGP) domain, which makes up ~10% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~4–6 in this domain), expect 1–1 from this objective — we provide 27 practice questions to prepare you well beyond it.
