JNCIA-Junos: Juniper Networks Certified Associate – Junos — Question 5

How does the PFE determine how to forward transit traffic?

Answer options

• A. The PFE determines network destinations itself based on the RE's routing table.
• B. The PFE uses the forwarding table provided by the RE.
• C. The PFE performs a destination lookup based on its own routing table.
• D. The PFE uses the routing table provided by the RE.

Correct answer: B

Explanation

The correct answer is B because the PFE relies on the forwarding table supplied by the RE to manage transit traffic. Option A is incorrect as the PFE does not independently determine destinations; it uses the RE's forwarding information. Options C and D are misleading as they imply the PFE has its own routing table, which it does not use for forwarding decisions.
