JNCIA-Junos: Juniper Networks Certified Associate – Junos (2022) — Question 94

Which two statements about exception traffic processing are correct? (Choose two.)

Answer options

• A. By default, a rate-limiter for exception traffic exists on the internal link between the control plane and the forwarding plane.
• B. By default, no rate-limiter for exception traffic exists on the internal link between the control plane and the forwarding plane.
• C. When congestion occurs, local and control traffic are given preference.
• D. When congestion occurs, only exception traffic is given preference.

Correct answer: A, C

Explanation

The correct answer is A and C because there is indeed a rate-limiter for exception traffic by default, which helps manage bandwidth between the control plane and forwarding plane. Option B is incorrect as it contradicts the established behavior of the system, while D is wrong because both local and control traffic are prioritized over exception traffic during congestion.
