CCNA Routing and Switching (legacy) — Question 21

Which function does the IP SLAs ICMP Echo operation perform to assist with troubleshooting?

Answer options

• A. packet-loss detection
• B. congestion detection
• C. hop-by-hop response time
• D. one way jitter measurements

Correct answer: A

Explanation

The correct answer is A because the IP SLAs ICMP Echo operation specifically measures and reports on packet loss between two endpoints, which is crucial for identifying network issues. The other options, while relevant to network performance, do not directly relate to the primary function of the ICMP Echo operation.
