JNCIS-ENT: Juniper Networks Certified Specialist – Enterprise Routing and Switching (2025) — Question 32

Which two statements correctly describe RSTP port roles? (Choose two.)

Answer options

• A. The designated port forwards data to the downstream network segment or device.
• B. The backup port is used as a backup for the root port.
• C. The alternate port is a standby port for an edge port.
• D. The root port is responsible for forwarding data to the root bridge.

Correct answer: A, D

Explanation

Answer A is correct because the designated port is responsible for forwarding traffic to the downstream network. Answer D is also correct, as the root port is indeed tasked with sending data towards the root bridge. Options B and C are incorrect because the backup port does not exist in RSTP terminology, and the alternate port does not act as a standby for an edge port.
