CCNA Introduction to Networks Chapter 6
Which router bootup sequence is correct?- ✔✔1 - perform the POST and load the bootstrap
program
2 - locate and load the Cisco IOS software
3 - locate and load the startup configuration file or enter setup mode
%
Refer to curriculum topic: 6.3.2
When a router is powered on, it undergoes a POST to verify that the hardware is functional, after
which it proceeds by locating and loading the Cisco IOS software and then loading the startup
configuration file if one is present.
0
During troubleshooting procedures, from which location will most Cisco routers load a limited IOS? -
✔✔ROM
Refer to curriculum topic: 6.3.1
ROM is used to store bootup instructions, basic diagnostic software, and a copy of a limited IOS.
0
NVRAM stores the startup configuration file. RAM provides temporary storage of the running
configuration file. Flash is used to store the full Cisco IOS on a device.

Open the PT activity. Perform the tasks in the activity instructions and then answer the question.
Which interfaces in each router are active and operational? - ✔✔R1: G0/0 and S0/0/0
R2: G0/1 and S0/0/0
R1>enable

Refer to curriculum topic: 6.4.2
The command to use for this activity is show ip interface brief in each router. The active and
operational interfaces are represented by the value "up" in the "Status" and "Protocol" columns. The
interfaces in R1 with these characteristics are G0/0 and S0/0/0. In R2 they are G0/1 and S0/0/0.
Which two files are loaded into RAM by the router when it boots? (Choose two.) - ✔✔startup
0
configuration
IOS image
Refer to curriculum topic: 6.3.2
0
A router loads the IOS image file and startup configuration file into RAM when it boots. Then the
startup configuration file is copied into RAM as the running configuration file. The power-on self-test
(POST) is a process that occurs on almost every computer during bootup. A bootstrap program is a
program that is executed just after the POST.
1
During the boot process, in what memory location will the router bootstrap program look for the IOS
image if a TFTP server is not used? - ✔✔flash
Refer to curriculum topic: 6.3.2
The IOS image is typically stored in flash memory. If the image is not in flash memory when the router
boots, the router bootstrap program can look for it on a TFTP server.
What is the command netstat -r used for? - ✔✔to display the host routing table
Refer to curriculum topic: 6.2.1
The command netstat -r displays the host routing table to verify the routes and costs that a computer
uses to communicate to certain networks.
What are two functions that are provided by the network layer? (Choose two.) - ✔✔directing data
packets to destination hosts on other networks
providing end devices with a unique network identifier
