Huawei Certified ICT Associate – Data Center Network (HCIA-DCN) — Question 26

Which of the following statements about the functions and packet encapsulation of the ARP protocol is true?

Answer options

• A. The ARP cache on a network device can be obtained only through the ARP protocol.
• B. The MAC address and UUID of the destination device can be obtained through ARP.
• C. ARP can be deployed on PPP and HDLC links.
• D. ARP packets are encapsulated over Ethernet.

Correct answer: D

Explanation

The correct answer is D because ARP packets are indeed encapsulated within Ethernet frames for transmission on local networks. Options A and B are incorrect as the ARP cache can be accessed through various means, and ARP does not provide UUID information. Option C is misleading since ARP is primarily associated with Ethernet and not typically used over PPP and HDLC links.
