QUESTION: 193

A technician is attempting to log in to a Linux server as root but cannot remember the administrator password.
Which of the following is the LEAST destructive method of resetting the administrator password?

Boot using a Linux live CD and mount the hard disk to /mnt. Change to the /mnt/etc directory. Edit the passwd file found in that directory.
Reinstall the OS in overlay mode. Reset the root password from the install GUI screen.
Adjust the GRUB boot parameters to boot into single-user mode. Run passwd from the command prompt.
Boot using a Linux live CD and mount the hard disk to /mnt. SCP the /etc directory from a known accessible server to /mnt/etc.

Answer(s): C

Explanation:

This is the least destructive method of resetting the administrator password because it does not require modifying any files or reinstalling the OS. It only requires changing the boot parameters temporarily and running a command to change the password.

QUESTION: 194

A server shut down after an extended power outage.
When power was restored, the system failed to start. A few seconds into booting, the Num Lock, Scroll Lock, and Caps Lock LEDs flashed several times, and the system stopped.
Which of the following is the MOST likely cause of the issue?

The keyboard is defective and needs to be replaced.
The system failed before the display card initialized.
The power supply is faulty and is shutting down the system.
The NIC has failed, and the system cannot make a network connection.

Answer(s): B

Explanation:

This is the most likely cause of the issue because the keyboard LED flash indicates a POST error code. If the display card is not initialized, the system cannot show any error messages on the screen and will stop booting.

QUESTION: 195

Which of the following BEST describes overprovisioning in a virtual server environment?

Committing more virtual resources to virtual machines than there are physical resources present
Installing more physical hardware than is necessary to run the virtual environment to allow for future expansion
Allowing a virtual machine to utilize more resources than are allocated to it based on the server load
Ensuring there are enough physical resources to sustain the complete virtual environment in the event of a host failure

Answer(s): A

Explanation:

This is the best definition of overprovisioning in a virtual server environment because it means allocating more CPU, memory, disk, or network resources to the virtual machines than what is actually available on the physical host. This can lead to performance issues and resource contention.

QUESTION: 196

A newly installed server is accessible to local users, but remote users are unable to connect.
Which of the following is MOST likely misconfigured?

The IP address
The default gateway
The VLAN
The subnet mask

Answer(s): B

Explanation:

This is the most likely misconfigured setting because the default gateway is the router that connects the local network to other networks. If the default gateway is incorrect, the server will not be able to communicate with remote users or devices outside its own subnet.
