1. What is the name of the routing protocol process on a Junos OS device?

A) chassisd
B) cosd
C) snmpd
D) rpd

2. Click the Exhibit button.

You recently added an EBGP neighbor to R1 and you are receiving a single BGP route for their internal network. You notice that on R2 the route learned from C1 is being marked as hidden because the next hop is unusable.
Referring to the exhibit, what should you do to resolve the problem?

A) Create a next-hop-self import policy on R1 and apply this policy to EBGP.
B) Create a next-hop-self import policy on R2 and apply this policy to IBGP.
C) Create a next-hop-self export policy on R1 and apply this policy to IBGP.
D) Create a next-hop-self import policy and apply this policy to IBGP.
