Hi all,

Long time no see. Thanks Christian for providing this. 100% guaranteed

1. Which two statements are true about IPv6 link local addresses? (Choose two.)

They begin with the 2000::/3 prefix.
They begin with the FE80::/10 prefix.
They are assigned by IANA to an organization.
They must be manually configured by the administrator.
They are assigned to a host by a stateless autoconfiguration process.

2. Refer to the exhibit. What is another way to represent this IPv6 address?

2031::130F::9C0::130B
2031::130F::9C0:0:130B
2031:0:130F::9C0::130B
2031:0:130F::9C0:0:130B

3. Refer to the exhibit. A host connected to Fa0/0 is unable to acquire an IP address from the DHCP server. The output of the debug ip dhcp server command shows "DHCPD: there is no address pool for 192.168.3.17". What is the problem?

The address 192.168.3.17 address is already in use by Fa0/0.
The pool of addresses for the 192Network pool is configured incorrectly.
The ip helper-address command should be used on the Fa0/0 interface.
The 192.168.3.17 address has not been excluded from the 192Network pool.

4. What will be the result of adding the command ip dhcp excluded-address 10.10.4.1 10.10.4.5 to the configuration of a local router that has been configured as a DHCP server?

Traffic that is destined for 10.10.4.1 and 10.10.4.5 will be dropped by the router.
Traffic will not be routed from clients with addresses between 10.10.4.1 and 10.10.4.5.
The DHCP server will not issue the addresses ranging from 10.10.4.1 to 10.10.4.5.
The router will ignore all traffic that comes from the DHCP servers with addresses 10.10.4.1 and 10.10.4.5.

5. Refer to the exhibit. PC1, PC2, and PC3 are configured with dynamic address assignments. PC2 is assigned an IP address from the DHCP server. What would account for the IP addresses that are currently assigned to PC1 and PC3?

Switch S2 port Fa0/12 is configured for full-duplex.
These addresses were included in the DHCP server pools.
Router R1 has a misconfigured IP address on interface Fa1/0.
R1 interface Fa0/0 is not in the same network as the DHCP server.
R1 interfaces Fa0/0 and Fa1/0 do not include the ip helper-address command.

Beleive it or not, this is a fairly common question and in all reality the answer is quite simple. Adding a user to the sudoers list on a fully installed Linux system such as Debian is only possible via the command visudo. Users in the sudoers list are allowed the privileges to run commands and open files as the root user.

We will show you how adding a new sudoer is quickly done.

Open a Root Terminal and type visudo (to access and edit the list)

Using the up/down arrows, navigate to the bottom of the sudoers file that is now displayed in the terminal

Just under the line that looks like the following:

        root ALL=(ALL) ALL

Add the following (replacing user with your actual username):

        user ALL=(ALL) ALL

Now press Ctrl+X and press Y when promted to save

That's it, your new user now has root privileges!

Some site might claim that they have the latest 2011 version of CCNA module test, but actually the module test hasn't changed from 2008. Trust me. I'm serious. Only final tests changed

Here is one example: I found this question on a "2011 version" of E2 - Module 1:

If a router cannot find a valid configuration file during the startup sequence, what will occur?

But actually, this question is already in my blog post about E2 - Module 1 on November 11, 2008:

http://www.cnttbachkhoa.com/blog/2008-11-06-ccna-v4-e2-module-1-100/

Don't panic. My site has the most updated questions and answer :)

Recently, I've tried to share a URL on Facebook. They displayed (No Title) on status box without any further information. I checked my site and found that I cannot even click on the like button at the end of each post. I'm gonna report this problem to Facebook. But how?
