Implementing Cisco Enterprise Advanced Routing and Services (ENARSI) — Question 416

A CoPP policy is applied for receiving SSH traffic from the WAN interface on a Cisco ISR4321 router. However, the SSH response from the router is abnormal and stuck during the high link utilization. The problem is identified as SSH traffic does not match in the ACL. Which action resolves the issue?

Answer options

• A. Apply CoPP on the control plane interface.
• B. Apply CoPP on the WAN interface inbound direction.
• C. Rate-limit SSH traffic to ensure dedicated bandwidth.
• D. Increase the IP precedence value of SSH traffic to 6.

Correct answer: A

Explanation

The correct answer is A because applying CoPP on the control plane interface ensures that the control traffic, like SSH, is properly managed and prioritized. The other options do not directly address the issue of ACL matching and may not provide the necessary prioritization to handle SSH traffic effectively.
