When multiple BGP paths exist to the same destination, what does the router do by default?

It selects the best path and installs only that path

It installs all paths in the routing table

In recursive next hop resolution, what is the final result of the lookup process?

The outgoing interface and next-hop address for forwarding

When a BGP next hop is not directly connected, what must the router do to resolve it?

Install the route without resolving the next hop

Perform a recursive lookup through the IGP or static routes

Send an ICMP echo request to the next hop

Use the default route if no specific route exists

Router R1 has an iBGP session with Router R2. R1 learns a route from an eBGP peer with a next hop of 203.0.113.1. R1 is configured with 'next-hop-self' on the iBGP session to R2. What next hop will R2 see for this route?

R1's IP address used for the iBGP session

The IP address of R1's interface facing the eBGP peer

R2's IP address used for the iBGP session

A service provider has an eBGP session between Router A (10.0.0.1/30) and Router B (10.0.0.2/30). Router B is advertising 192.168.1.0/24 to Router A. On Router A, the BGP route for 192.168.1.0/24 shows the next hop as 10.0.0.2, and the route is active in the routing table. However, when Router A attempts to forward traffic to 192.168.1.1, the packets are dropped even though the BGP route is present. Which configuration change on Router A would most likely resolve this issue?

Configure 'next-hop-self' on the eBGP session to Router B

Verify that the interface connected to 10.0.0.2 is up and has an IP address assigned

Add a static route for 192.168.1.0/24 pointing to 10.0.0.2

Change the BGP route preference to a lower value

Part of the BGP domain, which makes up ~22% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~8–13 in this domain), expect 1–1 from this objective — we provide 18 practice questions to prepare you well beyond it.
