A. B. C. D.A
The IP SLAs (Internet Protocol Service Level Agreement) ICMP Echo operation is a tool used to measure the performance of network connectivity between devices. Specifically, this operation sends a series of ICMP (Internet Control Message Protocol) echo requests from one device to another and measures the response time for each request.
The primary function of the IP SLAs ICMP Echo operation is to assist with troubleshooting network connectivity issues. By measuring the response time for each echo request, network administrators can identify issues such as high latency, packet loss, and congestion.
Option A: Packet-loss detection is one of the primary functions of the IP SLAs ICMP Echo operation. When a device sends an ICMP echo request to another device, it expects to receive an ICMP echo reply in response. If the device does not receive a reply, it indicates that some of the packets have been lost, and this information can be used to troubleshoot network connectivity issues.
Option B: Congestion detection is not the primary function of the IP SLAs ICMP Echo operation. However, measuring response times can indirectly help identify congestion issues, as increased response times are often indicative of network congestion.
Option C: Hop-by-hop response time is the primary function of the IP SLAs ICMP Echo operation. The operation measures the time it takes for an ICMP echo request to be sent from one device to another, and for the corresponding ICMP echo reply to be received. This information can be used to troubleshoot network connectivity issues, as increased response times can indicate network congestion or other connectivity issues.
Option D: One-way jitter measurements are not the primary function of the IP SLAs ICMP Echo operation. Jitter refers to the variation in packet delay or packet arrival times, and while measuring response times can indirectly help identify jitter issues, the ICMP Echo operation is primarily used for measuring hop-by-hop response times.
Therefore, the correct answer is option C: hop-by-hop response time.
