To comply with the user requirements, the best options are to install the OS on a RAID 1 array, configure RAID 5 for the application data, and use SSD hard drives for the data application array. Here is why:

• RAID 1 is a mirroring technique that creates an exact copy of data on two disks. This provides redundancy and fault tolerance in case of hard drive failure. RAID 1 also improves read performance since either disk can be read at the same time. Therefore, installing the OS on a RAID 1 array meets the first requirement of separating the OS from the application data and protecting it from hard drive failure.
• RAID 5 is a striping technique with parity that distributes data and parity blocks across three or more disks. This provides improved performance and storage efficiency compared to RAID 1, as well as fault tolerance in case of a single disk failure. Therefore, configuring RAID 5 for the application data meets the second and third requirements of providing high IOPS performance and data availability.
• SSD hard drives are solid-state drives that use flash memory to store data. They have no moving parts and offer faster read and write speeds, lower latency, and lower power consumption than traditional HDDs. Therefore, using SSD hard drives for the data application array meets the second requirement of providing high IOPS performance.

A hot site is a type of disaster recovery site that has all the equipment and data ready to resume operations as soon as possible after a disaster. A hot site is usually located in a different geographic area than the primary site and has redundant power, cooling, network, and security systems. A hot site is best for the company that wants to recover in the shortest possible time and does not want customer data to egress to non-company equipment. A warm site is a type of disaster recovery site that has some equipment and data ready, but requires some configuration and restoration before resuming operations. A cold site is a type of disaster recovery site that has only basic infrastructure and space available, but requires significant setup and installation before resuming operations. Cloud recovery is a type of disaster recovery service that uses cloud-based resources and platforms to store backups and restore data and applications after a disaster.

A warranty is a type of asset management documentation that is commonly used as a reference when processing the replacement of a faulty server component. A warranty is a guarantee from the manufacturer or vendor that covers the repair or replacement of defective parts within a specified period of time. A purchase order, a license, or a baseline document are not directly related to the replacement of a faulty server component. References: [CompTIA Server+ Certification Exam Objectives], Domain 1.0: Server Architecture, Objective 1.4: Explain asset management and documentation processes.

The net use command is a Windows command that can be used to create a batch script to map multiple shares. The net use command can connect or disconnect a computer from a shared resource, such as a network drive or a printer, or display information about computer connections. The syntax of the net use command is:

net use [devicename | *] [\\computername\sharename[\u0003volume] [password | *]] [/user:[domainname\]username] [/user:[dotted domain name\]username] [/user:[[username@dotted domain name] [/savecred] [/smartcard] [{/delete | /persistent:{yes | no}}]

where:

devicename = the drive letter or printer port to assign to the shared resource computername = the name of the computer that provides access to the shared resource sharename = the name of the shared resource password = the password needed to access the shared resource /user = specifies a different username to make the connection /savecred = stores the provided credentials for future use /smartcard = uses a smart card for authentication /delete = cancels a network connection and removes the connection from the list of persistent connections /persistent = controls whether the connection is restored at logon

To create a batch script to map multiple shares, you can use the net use command with different drive letters and share names, for example:

net use W: \\computer1\share1 net use X: \\computer2\share2 net use Y: \\computer3\share3

You can also add other options, such as passwords, usernames, or persistence, as needed. To save the batch script, you can use Notepad or any text editor and save the file with a .bat extension12.
