Huawei Certified ICT Associate – Data Center Network (HCIA-DCN) — Question 14

Which of the following advantages is/are inter-VLAN route interworking in one-arm routing mode?

Answer options

• A. Reduced the number of links
• B. Reduced the use of IP addresses
• C. Reduced the number of devices
• D. Reduced the number of entries in the routing table

Correct answer: A

Explanation

The correct answer is A, as one-arm routing consolidates VLANs over a single link, minimizing the number of physical connections required. Options B, C, and D are incorrect because one-arm routing does not inherently reduce the use of IP addresses, the number of devices involved, or the routing table entries in a significant way.
