Correct Answer: B

Per concurrent user licensing is a model that allows a fixed number of users to access the software at any one point in time. This model is best for the company that wants to deploy software to all users, but very few of them will be using the software at any one point in time. This way, the company can save money by paying only for the number of simultaneous users, rather than for every user who has access to the software. Per site licensing is a model that allows unlimited users within a specific location to use the software. Per core licensing is a model that charges based on the number of processor cores on the server where the software is installed. Per instance licensing is a model that charges based on the number of copies of the software running on different servers or virtual machines.

Correct Answer: C

If a server has three hard drives configured in a RAID 5 array, it means that the data is striped across all three drives with parity information. RAID 5 can tolerate one drive failure without losing data, but not two or more. If there are multiple

failed hard drives, the RAID 5 array will become corrupted and the OS will not load. The other options are not likely to cause the issue, as the server passes POST, the CPU and RAM are seated correctly, the BIOS settings are correct, and

the OS loads from a bootable USB drive. RAID 5 does not require four drives, it can work with three or more. References:

Correct Answer: C

A login script is a file that contains commands or instructions that are executed when a user logs into a system or network. A login script can be used to map a network drive to a user profile, which means that the user will have access to a shared folder or resource on another computer or server. A login script can be written in various languages, such as batch, PowerShell, or VBScript, and can be assigned to a user or a group using tools such as Group Policy or Active Directory . A system service (A) is a program that runs in the background and performs tasks that are essential for the operation of the system, such as security, networking, or hardware management. A system service does not map a network drive to a user profile. A network service (B) is a program that provides functionality or resources to other programs or devices over a network, such as file sharing, printing, or web hosting. A network service does not map a network drive to a user profile. A kickstart script (D) is a file that contains configuration settings and commands for automated installation of Linux operating systems. A kickstart script does not map a network drive to a user profile.

Correct Answer: B

Correct Answer: B

This is the most appropriate way to complete the task because it follows the best practices of cable management. Cable management is a process of organizing and securing cables in a rack or a server room to improve airflow, accessibility,

safety, and aesthetics. Running the network cables up the left side and the power cables down the right side of the rack helps to avoid cable clutter, interference, and confusion. It also makes it easier to trace and troubleshoot cables if

needed. Using appropriate-length cables also helps to reduce cable slack and excess. Wiring the cables through the cable management arm may cause stress and damage to the cables when moving the server in or out of the rack. Using the

longest cables possible may create cable loops and tangles that can block airflow and increase fire hazards. Installing an Ethernet patch panel and a PDU (Power Distribution Unit) may be useful for accommodating more network and power

cables, but not necessary for a single server.

Correct Answer: A

Correct Answer: D

The administrator should use the command chmod 754 /home/Ann to resolve the issue without granting unnecessary permissions.The chmod command is used to change the permissions of files and directories on a Linux server. The permissions are represented by three numbers, each ranging from 0 to 7, that correspond to the read ? write (w), and execute (x) permissions for the owner, group, and others respectively. The numbers are calculated by adding up the values of each permission: r = 4, w = 2, x = 1. For example, 7 means rwx (4 + 2 + 1), 6 means rw- (4 + 2), 5 means r-x (4 + 1), etc. In this case, Ann's home directory has the permissions dr-xr-xr? which means that only the owner (d) can read ?and

execute (x) the directory, and the group and others can only read ?and execute (x) but not write (w) to it. This prevents Ann from saving files to her home directory. To fix this issue, the administrator should grant write permission to the owner by using chmod 754 /home/Ann, which means that the owner can read ? write (w), and execute (x) the directory, the group can read ?and execute (x) but not write (w) to it, and others can only read ?but not write (w) or execute (x) it. This way, Ann can save files to her home directory without giving unnecessary permissions to others.

Correct Answer: DE

Correct Answer: C

The most efficient step would be to replace both failed drives at the same time. This will allow for the quickest recovery time since both drives have failed and need to be replaced to restore data redundancy.

Replacing one drive at a time, waiting for a rebuild, and then replacing the next drive will increase the risk of data loss if another drive fails during the rebuild process. Shutting down the server to replace the drives will result in extended downtime. Replacing all the drives in both degraded arrays is not necessary, as only the two failed drives need to be replaced.

Correct Answer: D

RAID 10 would provide the MOST storage as well as disk redundancy out of the given options.

RAID 0 provides no redundancy and only offers increased performance by striping data across multiple drives.

RAID 1 provides disk redundancy but only half the total storage capacity since each disk is a mirror of the other.

RAID 5 provides a good balance of storage and redundancy by striping data across multiple disks with parity data distributed among the disks. However, it requires at least three drives and can only withstand the failure of one disk.

RAID 10, also known as RAID 1+0, provides both disk redundancy and increased storage capacity by mirroring two drives and then striping data across the mirrored pairs. This configuration requires at least four drives and can withstand the

failure of one drive in each mirrored pair.
