A CPU fan is a component that cools down the CPU, which is the main processor of the computer. If the CPU fan is failing, it can cause the computer to slow down and the fans to alternate between

silent and very loud12. This is because the CPU fan cannot maintain a consistent speed and airflow to keep the CPU at a safe temperature. When the CPU gets too hot, it throttles its performance to avoid

overheating, which results in a slower computer. The other fans in the computer also try to compensate for the lack of cooling from the CPU fan by spinning faster and louder2.

The error message "Reboot and Select Proper Boot Device" indicates that the computer cannot find the boot device that contains the operating system12. This can happen if the hard drive that stores

the operating system is damaged or failed, and the BIOS cannot detect it or read from it23. A failed hard drive can also cause other symptoms such as clicking noises, corrupted files, or slow

performance4.

RAID stands for Redundant Array of Independent Disks, which is a technology that combines multiple disks into a logical unit to improve performance, reliability, or both. There are different types of RAID

levels that use different methods of data distribution and redundancy.

RAID 0 is a level that stripes data across multiple disks without any redundancy. It offers the highest performance but no fault tolerance. If any disk fails, the entire array is lost.

RAID 1 is a level that mirrors data across two disks. It offers the lowest performance but the highest fault tolerance. It can survive the failure of one disk.

RAID 5 is a level that stripes data across multiple disks with parity information. It offers a balance between performance and fault tolerance. It can survive the failure of one disk, but not two or more

disks.

RAID 10 is a level that combines RAID 1 and RAID 0. It creates a striped array of mirrored pairs. It offers high performance and high fault tolerance. It can survive the failure of one disk in each pair, or

multiple disks in different pairs.

Therefore, if the server administrator wants to rebuild the array to withstand a potential multidrive failure in the future, RAID 10 is the most likely choice.

Telnet is an unsecure remote access protocol that allows a user to connect to a remote device and execute commands on it12. Telnet does not encrypt the data that is transmitted between the user

and the device, which means that anyone who intercepts the network traffic can read the information, including usernames and passwords12. Telnet also does not authenticate the user or

the device, which means that anyone can impersonate either party and gain unauthorized access1.

TPM stands for Trusted Platform Module, which is a hardware component that securely stores encryption keys and other sensitive data12. TPM can be used to enable hard drive encryption, which

is a technology that encrypts the data stored on a hard drive using sophisticated mathematical functions34. Hard drive encryption protects the data from unauthorized access in case the hard drive

is lost, stolen, or tampered with.

A client-side hypervisor is a virtual machine monitor (VMM) that resides in and virtualizes a user’s computer, allowing it to run multiple operating systems (or virtual machines) on shared hardware12.

A client-side hypervisor can be useful for a software developer who needs to test an application in many environments, such as different versions of Windows, Linux, or Mac OS. By using a client-side

hypervisor, the developer can switch between different virtual machines without rebooting the computer or using multiple physical devices3.

A digitizer is a component that handles touch-screen operation on a mobile device. It is a layer of material that detects and converts the touch of a finger or a stylus into an electrical signal that can be

processed by the device12. A digitizer works with a display screen to create a touch-screen interface that allows a user to interact with the device by touching pictures or words on the screen.

The message prompting to press "OK" indicates that the printer is waiting for a user input. This suggests that there is some issue with the printer settings, and the most probable cause is that the

default paper type has been changed, and the printer needs the user to confirm the paper type before proceeding with the print job. This is a common issue that can occur when the default paper

type is not set correctly or has been changed without the user's knowledge.

The shared-tenant model for a cloud deployment, also known as a multi-tenant model, allows multiple customers to use the same resources and infrastructure of the cloud service provider, with

each customer's data and applications isolated from one another. This model is often chosen for cost savings, as resources are shared and users only pay for what they use. Therefore, the MOST likely

reason that an administrator chose this model is A. Cost savings.
