Changed SK0-005 Exam Questions

Sinceport 3306(MySQL) is open on the local workstation as confirmed by the Nmap scan, the next logical step is to checknetwork 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.

CompTIA Server+ Reference:This topic relates toSK0-005 Objective 2.4: Troubleshoot common server problems.

When a server is acting strangely after a patch and services that should be enabled are disabled, it’s often a good first step to set the services to restart automatically and then reboot the server. This can resolve many issues as it ensures that all services start correctly upon reboot

Comprehensive Detailed Explanation with all CompTIA Server+ SK0-005 Study Guide References:Event logsare the primary source for tracking server reboots and other system events. Logs such as the system log in Linux (/var/log/syslog or /var/log/messages) or the Event Viewer in Windows provide timestamps and details about shutdowns, restarts, and boot processes. Regular monitoring ensures that unplanned reboots or system errors are identified and addressed.

Uptime:Indicates how long the server has been running since the last reboot but does not provide detailed reboot evidence.

IOPS:Refers to input/output operations per second, unrelated to reboots.

CPU utilization:Reflects processor activity but offers no reboot evidence.

An action that the administrator should take to harden the hardware of a new server is to set a BIOS password. BIOS (Basic Input/Output System) is a firmware that initializes the hardware components and settings of a system before loading the operating system. BIOS password is a security feature that requires a user to enter a password before accessing or modifying the BIOS settings or booting up the system. By setting a BIOS password, the administrator can prevent unauthorized or malicious users from changing the hardware configuration or boot order of the server.
