CCNA – IOS Questions

May 24th, 2015 Go to comments

Note: If you are not sure about Cisco IOS, please read our Cisco Router Boot Sequence Tutorial and Cisco Command Line Interface CLI.

Question 1

Question 2

Explanation

It is a waste to administratively shut down the interface. Moreover, someone can still access the virtual terminal interfaces via other interfaces -> A is not correct.

We can not physically secure a virtual interface because it is “virtual” -> B is not correct.

To apply an access list to a virtual terminal interface we must use the “access-class” command. The “access-group” command is only used to apply an access list to a physical interface -> C is not correct; E is correct.

The most simple way to secure the virtual terminal interface is to configure a username & password to prevent unauthorized login -> D is correct.

Question 3

Explanation

During the copy process, the router asked “Erasing flash before copying? [confirm]” and the administrator confirmed (by pressing Enter) so the flash was deleted.

Note: In this case, the flash has enough space to copy a new IOS without deleting the current one. The current IOS is deleted just because the administrator wants to do so. If the flash does not have enough space you will see an error message like this:

%Error copying tftp://192.168.2.167/ c1600-k8sy-mz.l23-16a.bin (Not enough space on device)

Question 4

Explanation

By using this command, all the (current and future) passwords are encrypted. This command is primarily useful for keeping unauthorized individuals from viewing your password in your configuration file.

Question 5

Explanation

A global command is a command in this form:

Device(config)#

This mode can affect the entire router/switch.

For more information about modes in Cisco devices, please read my Cisco Command Line Interface CLI tutorial.

Question 6

Question 7

Explanation

The ping command can be used to test if the local device can reach a specific destination -> A is correct.

“tracert” is not a valid command in Cisco IOS commands, the correct command should be “traceroute” -> B is not correct.

The ipconfig command is not a valid command in Cisco IOS too -> C is not correct.

The “show ip route” command can be used to view the routing table of the router. It is a very useful command to find out many connectivity problems (like directly connected networks, learned network via routing protocols…) -> D is correct.

“winipcfg” is an old tool in Windows 95/98 to view IP settings of the installed network interfaces. But it is not a valid command in Cisco IOS commands -> E is not correct.

The “show interfaces” command is used to check all the interfaces on the local device only. It has very limited information to trouble LAN connectivity problem but it is the most reasonable to choose -> F is acceptable.

Question 8

Question 9

Question 10

Explanation

By using the “service password-encryption” command, all the (current and future) passwords are encrypted.

Question 11

Explanation

The secret password (configured by the command “enable secret “) is always encrypted even if the “service password-encryption” command is not used. Moreover, the secret password is not removed from the configuration with this command, we still see it in encrypted form in the running-config -> D is not correct.

The “enable password ” does not encrypt the password and can be viewed in clear text in the running-config. By using the “service password-encryption” command, that password is encrypted (both current and future passwords) -> A is not correct, E is correct.

Answer B – Only the enable password will be encrypted seems to be correct but it implies the secret password will not be encrypted and stay in clear text, which is not correct.

For your information, the secret password is encrypted with MD5 one-way hash algorithm which is harder to break than the encryption algorithm used by the “service password-encryption” command.

    Passed the CCNA Finally! I had to take the CCNA twice, as I failed on my first attempt. However for my second, I used the e8ay dump to study the update that happened for the CCNA and passed the exam finally :D All Questions came from the dump. The e8ay dump has a total of 142 questions (58 + 84 updated questions) and the 4 variations of the ACL sims.

    Information to the exam:

    54 MC Questions
    1 ACL simulation
    1 EIGRP TSHOOT Simlet
    1 OSPF TShoot Simlet
    1 RIPv2 Simlet

    Total of 58 questions.

    If you would like to check out the materials I used, here you go:

    Hey guys, I just wrote now in USA. I Passed 200-601 with 92%. This dumps http://www.grades4sure.com/200-601-exam-questions.html is valid but a few answers are wrong. Although I don’t expect to pass with a full score, right? If your aim is just to pass the exam, only by memorizing the dumps is enough. But if you want to master skills, you really need to practice more.
