The technician should use port 22 to configure a server that requires secure remote access. Port 22 is the default port for Secure Shell (SSH), which is a protocol that allows secure remote login and command execution over a network connection using a command-line interface (CLI). SSH encrypts both the authentication and data transmission between the client and the server, preventing eavesdropping, tampering, or spoofing. SSH can be used to perform various tasks on a server remotely, such as configuration, administration, maintenance, troubleshooting, etc.

LVM (Logical Volume Manager) is a tool that allows the technician to increase a partition’s size in the future without reformatting it on a Linux server. LVM creates logical volumes that can span across multiple physical disks or partitions and can be resized dynamically without losing data. LVM also provides other features such as snapshots, encryption, and RAID. DiskPart, fdisk, and Format are tools that can be used to partition and format disks, but they do not allow increasing a partition’s size without reformatting it. References:

Drives, fans, and power supplies are server components that can most commonly be replaced without downtime if they are hot-swappable. Hot-swappable components can be removed and inserted while the server is running, without affecting its operation or performance. Drives store data and applications, fans cool down the server components, and power supplies provide electricity to the server. Replacing these components can prevent data loss, overheating, or power failure. References: CompTIA Server+ Certification Exam Objectives, Domain 2.0: Hardware, Objective 2.2: Given a scenario, install, configure and maintain server components.

A core installation is a type of installation method that is best suited to meet the company policy that states no one is to log in directly to the server. A core installation is a minimal installation option that is available when deploying some editions of Windows Server. A core installation includes most but not all server roles and features, but does not include a graphical user interface (GUI). A core installation can only be managed remotely using command-line tools such as PowerShell or Windows Admin Center, or using graphical tools such as Server Manager or Remote Desktop from another computer. This reduces the attack surface, resource consumption, and maintenance requirements of the server. A GUI installation is a type of installation method that includes a graphical user interface (GUI) and allows local or remote management using graphical tools or command-line tools. A virtualized installation is a type of installation method that involves creating and running one or more virtual machines on a physical host using a hypervisor such as Hyper-V or VMware. A clone installation is a type of installation method that involves creating an exact copy of an existing server’s configuration and data on another server using tools such as Sysprep or Clonezilla.
