Huawei Certified Network Associate – Routing and Switching (HCNA-RS, legacy) — Question 73

A network administrator wishes to assign an IP address to a router interface G0/0/0. Which of the following IP addresses can be assigned?

Answer options

• A. 192.168.10.112/30
• B. 237.6.1.2/24
• C. 145.4.2.55/26
• D. 127.3.1.4/28

Correct answer: C

Explanation

The correct answer is C, as 145.4.2.55/26 is a public IP address that can be assigned to a router interface. Option A is a private address that is valid, but not suitable for this context. Option B is also a public address, but outside of the typical range for router interfaces, and option D is a loopback address, which cannot be assigned to a physical interface.
