JNCIS-ENT: Juniper Networks Certified Specialist – Enterprise Routing and Switching (2025) — Question 58

You are configuring IBGP and you must ensure that reachability is maintained between participating routers, even if the physical topology changes.
Which two actions should you perform in this scenario? (Choose two.)

Answer options

• A. Configure DHCP on all IBGP devices.
• B. Configure an IGP within your IBGP network.
• C. Configure static routes to all IBGP peers.
• D. Configure IBGP peerings to loopback addresses.

Correct answer: B, D

Explanation

The correct answers are B and D because configuring an IGP allows for dynamic routing and adaptability to topology changes, while using loopback addresses for IBGP peerings ensures that the routers can still communicate even if their physical interfaces change. Options A and C are not effective for maintaining reachability in an IBGP setup; DHCP is irrelevant in this context and static routes do not adapt to physical topology changes.
