What are two characteristics of RAM on a Cisco device? (Choose two.)

Introduction

The Cisco Certified Network Associate (CCNA) 200-301 exam is a fundamental certification for networking professionals. One of the critical topics covered in the exam is understanding the components of a Cisco device, including Random Access Memory (RAM). RAM plays a crucial role in the operation of Cisco routers and switches.

In this article, we will discuss two key characteristics of RAM on a Cisco device and explain their significance in network operations. Additionally, we will highlight how Study4Pass can help you prepare effectively for the CCNA 200-301 exam, ensuring success on your first attempt.

What is RAM in a Cisco Device?

RAM (Random Access Memory) is a volatile memory component in Cisco devices that stores data temporarily while the device is operational. It is used for:

• Running the Cisco IOS (Internetwork Operating System)
• Storing routing tables, ARP caches, and packet buffers
• Maintaining temporary configurations (running-config)

Unlike NVRAM (Non-Volatile RAM) or Flash memory, RAM loses all stored data when the device is powered off.

Two Key Characteristics of RAM on a Cisco Device

1. RAM is Volatile Memory

One of the primary characteristics of RAM is that it is volatile, meaning it loses all stored data when the device is powered off or restarted. This is different from NVRAM, which retains data even after a power cycle.

Why is Volatility Important?

• Running Configuration Storage: The running-config file (active configuration) is stored in RAM. If the device reboots without saving the configuration to NVRAM, all changes are lost.
• Temporary Data Processing: RAM handles real-time operations such as packet forwarding, routing table updates, and ARP caching. Since these processes are dynamic, they do not need permanent storage.

Exam Tip (200-301 CCNA)

A common exam question may ask:
"What happens to the running-config if the router loses power?"
Answer: It is lost because it is stored in volatile RAM.

RAM Stores the Running IOS and Active Processes

Another essential characteristic of RAM is that it holds the running Cisco IOS and active system processes. When a Cisco device boots up, the IOS is loaded from Flash memory into RAM for execution.

Key Functions of RAM in IOS Operations:

• Executing IOS Commands: All CLI commands and system operations run in RAM.
• Buffering Network Traffic: RAM temporarily stores packets before forwarding them to their destination.
• Maintaining Routing Tables: Dynamic routing protocols (OSPF, EIGRP) store their tables in RAM for quick access.

Comparison with Other Memory Types

Exam Scenario (CCNA 200-301)

A question might ask:
"Where does a router store the running IOS during operation?"
Answer: RAM (The IOS is loaded from Flash into RAM for execution).

Why Understanding RAM is Crucial for the CCNA 200-301 Exam?

The CCNA 200-301 exam tests your knowledge of Cisco device operations, including memory functions. Key reasons why RAM is important:

1. Troubleshooting Boot Issues: If a device fails to load IOS, understanding RAM helps diagnose whether the issue is with Flash (IOS storage) or RAM (execution).
2. Configuration Management: Knowing that running-config is in RAM while startup-config is in NVRAM helps prevent configuration loss.
3. Performance Optimization: Devices with insufficient RAM may experience sluggish performance or crashes.
