CCNA Routing and Switching (legacy) — Question 2

Which function does the IP SLA 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: C

Explanation

The correct answer is C because the IP SLA ICMP ECHO operation measures the response time for packets as they traverse each hop, which is critical for identifying latency issues. Option A, packet-loss detection, does not specifically address response time, while B, congestion detection, focuses on network traffic issues rather than timing. Option D relates to jitter but does not provide the critical response time information needed for effective troubleshooting.
