Port 22 is used for SSH (Secure Shell), which is a secure and encrypted protocol for remote access to a server. Port 23 is used for Telnet, which is an insecure and unencrypted protocol for remote access. Port 990 is used for FTPS (File Transfer Protocol Secure), which is a secure and encrypted protocol for file transfer. The administrator should open port 22 and close port 23 to enable SSH and disable Telnet, as SSH is more secure and reliable than Telnet. The administrator does not need to open port 990, as FTPS is not required for making configuration changes123.

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. References:

* Scenario: Installing Windows on an 8TB drive, aiming for a single 8TB partition.
* Solution: Use the GPT (GUID Partition Table) option (Option C):
* GPT supports larger partitions (up to 18.4 million TB) compared to MBR (limited to 2TB).
* VMFS, ZFS, and LVM are unrelated to the partitioning scheme in Windows.

If users cannot access a new server by name, but the server does respond to a ping request using its IP address, it means that there is a problem with name resolution. The DNS (Domain Name System) is a service that maps hostnames to IP addresses and vice versa. Therefore, the best step to perform next is to examine the DNS to see if the new server record exists and matches its IP address. If not, the DNS record needs to be added or updated accordingly. Running the tracert command from a workstation would not help with name resolution, as it only shows the route taken by packets to reach a destination by IP address. Correcting the missing DHCP scope would not help either, as DHCP (Dynamic Host Configuration Protocol) only assigns IP addresses and other network settings to clients, but does not resolve names. Updating the workstation hosts file would be a temporary workaround, but not a permanent solution, as it would require manually editing every workstation's hosts file with the new server's name and IP address.

Comprehensive Detailed Explanation with all CompTIA Server+ SK0-005 Study Guide References:A Crash cart is a physical console that can be connected directly to the server's video output and keyboard
/mouse ports. This is useful in situations where remote management (OOB) is unavailable, allowing the administrator to directly view the server's display and interact with the system during the reboot process.
* IP KVM (Keyboard, Video, Mouse) is used for remote management, but the scenario specifically mentions no OOB management.
* Virtual administration console and Serial connections can be used for remote management or console access, but since OOB management is unavailable, a physical crash cart is the appropriate choice.
