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.

Since port 3306 (MySQL) is open on the local workstation as confirmed by the Nmap scan, the next logical step is to check network firewall rules. It’s possible that the workstation’s firewall or network-level security rules are blocking outbound or inbound traffic on port 3306, which is required for database access.

Edit the network firewall rules (Answer D): Ensuring the firewall allows traffic on port 3306 is the appropriate next step, especially since other workstations are not having the same issue.

Checking the database server (Option A): This is unnecessary because other workstations can access the server, confirming the server itself is functioning correctly.

Changing the database password (Option B): This would not resolve the issue of one workstation being unable to connect while others can.

Opening port 3306 on the server (Option C): The problem isn't server-side since other machines can connect without issue.

A misconfigured NTP (Network Time Protocol) on the client side can cause authentication issues because Active Directory relies on accurate time synchronization between clients and domain controllers for security purposes. If the clocks are out of sync, even by a few minutes, it can prevent users from authenticating to the domain.

NTP misconfiguration (Answer B): If the client machines have incorrect time settings, it can disrupt Kerberos-based authentication, which is time-sensitive.

Locked user accounts (Option A): While it can prevent login, it would affect individual users rather than a whole office.

MFA (Option C): Multi-factor authentication not working would typically cause a login issue but is less likely across an entire remote office.

Wrong time zone (Option D): While incorrect time zones can cause confusion, they usually don't prevent logins as long as the NTP server synchronizes the actual time correctly.

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.
