JNCIS-ENT: Juniper Networks Certified Specialist – Enterprise Routing and Switching (2025) — Question 57

You want to ensure traffic is routed through a GRE tunnel in this scenario, which two statements will satisfy this requirement? (Choose two.)

Answer options

• A. Tunnel endpoints must have a route that directs traffic into the tunnel.
• B. All intermediary devices must have a route to the tunnel endpoints.
• C. Keepalives must be used on stateless tunneling protocols.
• D. BFD must be used on the stateless tunneling protocols.

Correct answer: A, B

Explanation

Option A is correct because the tunnel endpoints must have a route directing traffic into the GRE tunnel for it to function properly. Option B is also correct since all intermediary devices must be aware of how to reach the tunnel endpoints to ensure successful traffic routing. Options C and D are incorrect as keepalives and BFD are not mandatory for stateless tunneling protocols.
