What two tasks are performed first in the router boot sequence?

Locate and load the operating system. Answers Explanation & Hints: There are three major steps to the router boot sequence: Perform Power-On-Self-Test (POST) and load the bootstrap program.

What is the boot up sequence of a router?

Router Boot-up During this self-test, the router executes diagnostics from ROM on several hardware components, including the CPU, RAM, and NVRAM. After the POST has been completed, the router executes the bootstrap program. After the POST, the bootstrap program is copied from ROM into RAM.

What are the four general steps for booting a Cisco router?

Cisco Router Boot Sequence, Cisco Router POST (Power On Self Test…

The router performs a POST (Power On Self Test).
The bootstrap program (The bootstrap is a program in ROM that is used to execute programs) checks the Configuration Register value to find where to load the IOS.

Which of the following is the first step in the router boot process?

Explanation: The following details the router boot process:

The router is powered on.
The router first runs Power-On Self Test (POST)
The bootstrap checks the Configuration Register value to specify where to load the IOS.
After the IOS is found, it is loaded into RAM.

What are two important functions of a router?

Their main job is to forward packets based upon a routing table. When doing so, they also provide traffic segmentation, multiple broadcast domains, and define network layer addressing subnets and networks.

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

ROM – Read Only Memory. This is where you router reads the microcode to start your boot process and basic checks of your router. There are four basic functions that are performed here as follows: POST – Power On Self Test.

How much memory does my Cisco router have?

To determine the amount of Flash and DRAM on a Cisco router, issue the show version command. Refer to the bold text in the output below. DRAM is divided logically, combining the two numbers to determine total DRAM. In this case, it is 45056K/4096K bytes (45056kB + 4096kB = 49152kB), which is equal to 48MB.

Which memory component on a Cisco router contains the dynamic system configuration?

DRAM. Dynamic random-access memory (DRAM) contains two types of memory: Primary, main, or processor memory, which is reserved for the CPU to execute Cisco IOS software and to hold the running configuration and routing tables.

What are the different memories used in a Cisco router?

Types of memory on a Cisco device

ROM (Read-only memory) – stores a bootstrap program that is used to initialize a boot process.
RAM (Random Access Memory) – the running configuration and routing tables of the device are stored here.
Flash memory – used to store IOS software images.

Which memory type holds the full IOS image for the router?

The Flash memory contains the full Operating System Image (IOS, Internetwork Operating System). This allows you to upgrade the OS without removing chips. Flash memory retains content when router is powered down or restarted.

What are the four main types of memory used in the router What does each memory on the router store?

Router Memory Types

ROM—Contains the power-on self test and the bootstrap program for the router.
NVRAM (nonvolatile RAM)—Stores the startup configuration file for the router.
Flash RAM—Flash is a special kind of ROM that you can actually erase and reprogram.

What are the modes in router?

There are mainly 5 modes in router:

User execution mode – As soon as the interface up message appears and press enter, the router> prompt will pop up.
Privileged mode –
Global configuration mode –
Interface configuration mode –
ROMMON mode –

What is the command for privileged EXEC mode?

To enter privileged EXEC mode, enter the enable command. Privileged EXEC From user EXEC mode, enter the enable command.

What is router mode vs AP mode?

Main Differences. The router acts as a hub that sets up a local area network and manages all of the devices and communication in it. An access point, on the other hand, is a sub-device within the local area network that provides another location for devices to connect from and enables more devices to be on the network.

How many modes does a router have?

Four Modes to Access and Configure a Cisco Router. Each mode has a unique command set. user EXEC mode is the initial startup mode. A router configuration session can be initiated using terminal emulation programs such as Kermit, HyperTerminal, or telnet.

Which 802.11 mode is best?

802.11g attempts to combine the best of both 802.11a and 802.11b. 802.11g supports bandwidth up to 54 Mbps, and it uses the 2.4 GHz frequency for greater range. 802.11g is backwards compatible with 802.11b, meaning that 802.11g access points will work with 802.11b wireless network adapters and vice versa.

Which wireless mode is best BGN?

802.11bgn Wi-Fi routers are single band. This means they support only the 2.4 GHz band. Wi-Fi 802.11g combines the best of both 802.11a and 802.11b. 802.11g that supports a bandwidth up to 54 Mbps, and it uses the 2.4 GHz frequency for greater range.

What is bridge mode and router mode?

Bridge mode lets you connect two routers without the risk of performance issues. Bridge mode is the configuration that disables the NAT feature on the modem and allows a router to function as a DHCP server without an IP Address conflict. Bridge mode fixes this by letting multiple routers share one single Wi-Fi network.

Which is better router or bridge mode?
