Supporting Cisco Routing and Switching Network Devices (RSTECH, legacy) — Question 9

Which type of memory is necessary for a router to boot?

Answer options

• A. DRAM
• B. PVDM
• C. NVRAM
• D. VRAM

Correct answer: C

Explanation

NVRAM is essential for a router's boot process as it stores the startup configuration file that the router needs to load during initialization. In contrast, DRAM is used for temporary storage of running configurations, PVDM is specific to voice processing, and VRAM is typically used for graphics storage, making them unsuitable for booting the router.
