Huawei Certified Network Associate – Routing and Switching (HCNA-RS, legacy) — Question 70

Which of the following storage devices is used to store the startup configuration files in a router?

Answer options

• A. SDRAM
• B. NVRAM
• C. Flash
• D. BootROM

Correct answer: B

Explanation

The correct answer is B, NVRAM, because it retains the startup configuration even when the router is powered off. SDRAM is volatile and loses its data when power is lost, Flash is used for IOS images, and BootROM is for the initial boot process, not for storing configuration files.
