Supporting Cisco Routing and Switching Network Devices (RSTECH) — Question 5

Which type of memory is used to permanently store Cisco IOS Software?

Answer options

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

Correct answer: A

Explanation

NVRAM is the correct answer because it retains the Cisco IOS Software even when the device is powered off, making it suitable for permanent storage. Flash memory is also used for storage but is not the primary type for IOS. SRAM and DRAM are types of volatile memory that do not retain data when power is lost.
