JNCIS-SP: Juniper Networks Certified Specialist – Service Provider Routing (2023) — Question 42

By default, which two statements are correct about switch ports on a Junos device? (Choose two.)

Answer options

• A. Trunk ports receive and transmit untagged traffic.
• B. Access ports receive and transmit tagged traffic.
• C. Trunk ports receive and transmit tagged traffic.
• D. Access ports receive and transmit untagged traffic.

Correct answer: C, D

Explanation

The correct answers are C and D because trunk ports are designed to carry tagged traffic to support multiple VLANs, while access ports handle untagged traffic which is typically associated with a single VLAN. Options A and B are incorrect as they misrepresent the traffic types associated with trunk and access ports.
