Supporting Cisco Routing and Switching Network Devices (RSTECH, legacy) — Question 3

Which type if memory is used to permanently store the Cisco IOS software?

Answer options

• A. Flash
• B. DRAM
• C. SRAM
• D. NVRAM

Correct answer: D

Explanation

The correct answer is D, NVRAM, because it retains data even when the device is powered off, making it suitable for storing the Cisco IOS software. Flash memory is also non-volatile but is typically used for larger storage needs, while DRAM and SRAM are volatile and lose their data when power is removed.
