Your router has two BGP routes for 192.0.2.0/24. Route A has origin IGP, local preference 100, and AS path 65001. Route B has origin Incomplete, local preference 100, and AS path 65001 65002. Which route will be selected as best?

Route A, because origin IGP is preferred over Incomplete

Route A, because it has the lower router ID

Route B, because Incomplete origin indicates a more reliable source

Route B, because it has the shorter AS path

Your router has two BGP routes for 172.16.0.0/16. Route 1 was learned from an eBGP peer. Route 2 was learned from an iBGP peer. Both have the same local preference, AS path length, origin, and MED. Which route will be selected?

Route 2, because iBGP routes are more stable

Route 2, because iBGP routes have a lower IGP metric to the next hop

Route 1, because it has the lower router ID

Route 1, because eBGP routes are preferred over iBGP routes

Your router has three BGP routes for 198.51.100.0/24. Route 1: origin IGP, local pref 100, AS path 65001. Route 2: origin EGP, local pref 100, AS path 65001 65002. Route 3: origin Incomplete, local pref 100, AS path 65001. Which route will be selected?

Route 2, because EGP origin is preferred over IGP

Route 3, because it has the same AS path as Route 1 but a lower router ID

Route 1, because origin IGP is preferred over EGP and Incomplete

Route 2, because it has the shortest AS path

What is the primary purpose of the MED attribute in BGP?

To determine the origin of a route

To influence outbound traffic from the local AS

To influence inbound traffic from a neighboring AS

To prefer eBGP routes over iBGP routes

During BGP path selection, when all earlier attributes are equal, which type of route is preferred?

The route with the lower router ID

Route/path Selection Process JN0-352 Practice Questions (Page 2)

Part of the BGP domain, which makes up ~13% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~5–8 in this domain), expect 1–1 from this objective — we provide 17 practice questions to prepare you well beyond it.
