Huawei Certified Network Associate – Routing and Switching (HCNA-RS, legacy) — Question 154

An AR2200 router in the company network cannot boot. In order to resolve this, the administrator wishes to update the VRP software.
What should he/she do?

Answer options

• A. The administrator should use a console cable to connect the router and host, and directly upgrade the device.
• B. The administrator should use FTP to transfer the VRP software, by configuring the AR2200 router as an FTP client.
• C. The administrator should use DHCP to boot the AR2200, and then use the AR2200 router as a TFTP client to download the VRP software from the server.
• D. The administrator should use the telnet command on the client to remote access the device, and upgrade the VRP software.

Correct answer: B

Explanation

The correct answer is B because using FTP allows for a reliable transfer of the VRP software to the AR2200. Option A is incorrect as a direct upgrade via console cable typically requires an operational state, which the router lacks. Option C misuses DHCP and TFTP, which are not the most efficient methods for software updates in this context. Option D is incorrect since telnet requires the router to be operational, which it is not in this scenario.
