Huawei Certified Network Associate – Routing and Switching (HCNA-RS, legacy) — Question 128

To provide the information about the IP addresses that a user packet traverses along the path to the destination, which of the following does Tracert record in each expired ICMP TTL packet?

Answer options

• A. Destination port
• B. Source port
• C. Destination IP address
• D. Source IP address

Correct answer: D

Explanation

The correct answer is D, as Tracert records the Source IP address of each router that the packet traverses, which helps in determining the path taken. Options A and B are incorrect because Tracert does not track port numbers; it focuses on IP addresses. Option C is also incorrect because while the Destination IP address is important, it is not what Tracert records for each hop.
