A system administrator is troubleshooting a critical internal file server configured with a hardware RAID 5 array consisting of four SATA SSDs. The storage console alerts that Drive 2 has failed and the array is operating in a degraded state. The administrator hot-swaps Drive 2 with a brand-new drive of identical manufacturer, capacity, and specification. However, upon insertion, the hardware RAID management utility flags the newly inserted disk as 'Foreign' or 'Unconfigured Drive' and fails to initiate the rebuild automatically. Which of the following is the most appropriate immediate action to rebuild the array while preserving existing data?

A field technician is troubleshooting a network printer that prints garbled text and random characters following a recent print server migration. The technician has already confirmed the physical hardware is operational by printing a clean self-test page directly from the printer's built-in control panel. Which of the following actions should the technician take next to establish a theory of probable cause? (Select TWO.)

A network administrator is investigating network problems in an expanded office branch. Users connected to the 2.4 GHz wireless network experience frequent disconnections and throughput drops during high-density hours. Simultaneously, several wired desktop users report that their workstations suddenly lost corporate network access, and running 'ipconfig' reveals IP addresses starting with 169.254.x.x. Which of the following actions should the administrator perform to resolve these issues? (Select TWO.)

An IT technician is configuring a custom workstation designed for 3D modeling that is equipped with two physical CPU sockets and 256 GB of system RAM. The system currently runs a clean installation of Windows 11 Home 64-bit. After initial setup, Task Manager shows that only one physical CPU socket and 128 GB of RAM are recognized by the operating system. Which operating system edition upgrade is required to fully support all installed hardware components while utilizing the minimum edition necessary?

A technician is troubleshooting a workstation that lost access to network share folders and the internet. Running `ipconfig` on the workstation yields an IP address of $169.254.89.12$ and a subnet mask of $255.255.0.0$. Which of the following statements correctly describe this network state? (Select TWO.)

A technician needs to replace a failed hot-swappable drive in a server's RAID 5 array. Place the recovery steps in the correct order from first to last to safely restore full array redundancy.

Match each Windows operating system feature on the left with its edition boundary or functional capability requirement on the right.

An IT administrator is auditing system deployment standards across various business units. Match each set of operational requirements or hardware limits to the minimum Windows 11 edition required to support it.

A mobile support technician is diagnosing several hardware and display issues reported on user devices. Match each mobile device symptom or hardware scenario on the left with its correct root cause or technical solution on the right.

A technician is servicing a server configured with a hardware RAID 5 storage array where a single hard drive has failed, leaving the volume operating in a degraded state. Arrange the standard recovery steps in the correct sequential order from first step to last step.

A technician is setting up a new high-performance laptop for a mobile user. The laptop features two physical USB Type-C ports located on the left side of the chassis. When the technician connects an external multi-display docking station to Port 1, the laptop charges normally, but the external monitors display no signal and external PCIe storage drives attached to the dock fail to mount. When the technician moves the dock cable to Port 2, both external displays light up immediately and the external drives function correctly. Which of the following best explains why Port 1 is unable to drive the external displays and PCIe devices?

A network technician is configuring three 2.4 GHz wireless access points within a small office to ensure complete coverage without frequency interference. Which of the following channel combinations should the technician assign to these access points?

A system technician is servicing an enterprise server configured with a hardware RAID 5 array that has generated a 'Degraded' status alert due to a single drive failure. In what chronological sequence should the technician perform the following steps to safely replace the failed drive and restore fault tolerance?

A desktop support technician needs to establish a continuous background log of CPU and memory performance data over a 24-hour period to capture an intermittent system slowdown. Which tool or feature should the technician configure to collect and export this long-term tracking data to a log file?

A system administrator has isolated an issue on a graphics workstation where internal PCI Express RAID storage disconnects under heavy load. The administrator tested a theory by swapping the RAID controller power lead to a separate, dedicated 12V PSU rail, which successfully confirmed that insufficient rail power was causing the dropouts. According to the CompTIA troubleshooting methodology, which TWO of the following actions should the technician perform NEXT before implementing preventative measures or closing the ticket? (Select TWO.)

A remote employee needs to access their office workstation using native Windows Remote Desktop (RDP). The workstation is currently running Windows 11 Home. When attempting to enable incoming RDP connections, the technician finds that the option is unavailable. Which of the following is required to enable incoming Remote Desktop host capabilities on this computer?

During an infrastructure audit at a regional clinic, a technician is assigned to resolve two independent connectivity problems. First, laptop computers frequently drop Wi-Fi signal when migrating between coverage zones in the 2.4 GHz band. Second, a newly connected wired workstation fails to communicate across the local subnet and displays an auto-configured IPv4 address of $169.254.88.15$. Which TWO troubleshooting actions should the technician implement?

Following an unexpected power outage, a system administrator replaces a damaged internal power supply on a high-availability network storage unit. The unit boots cleanly into the management dashboard. To adhere strictly to Step 5 (Verify full system functionality and, if applicable, implement preventive measures) of the CompTIA troubleshooting methodology, which of the following actions should the administrator perform?
