ICND2: Interconnecting Cisco Networking Devices Part 2 (legacy) — Question 8

Which statement about the IP SLAs ICMP Echo operation is true?

Answer options

• A. The frequency of the operation is specified in milliseconds.
• B. It is used to identify the best source interface from which to send traffic.
• C. It is configured in enable mode.
• D. It is used to determine the frequency of ICMP packets

Correct answer: B

Explanation

The correct answer, B, is accurate because the ICMP Echo operation is designed to select the best source interface for traffic transmission. Option A is incorrect as the frequency is not measured in milliseconds but rather in terms of intervals. Option C is misleading because while configuration occurs in enable mode, it does not specifically relate to the ICMP Echo operation's functionality. Option D is wrong as the operation does not focus on determining ICMP packet frequency.
