A systems engineer is assembling a high-performance workstation host designed to run multiple 64-bit client-side guest virtual machines simultaneously. The host must efficiently handle memory address translations between guest virtual memory and host physical memory while enabling direct hardware virtualization support. Which TWO of the following hardware features or firmware configurations are necessary on the host system to support these capabilities?

Match each client-side virtualization purpose on the left with its corresponding operational scenario on the right.

A desktop support technician is investigating a thermal label printer at a warehouse workstation that stopped printing following a system driver update. The technician has interviewed the user, confirmed the error logs, and established a theory that the newly installed driver is incompatible with the label printer hardware. According to the standard CompTIA troubleshooting methodology, which of the following actions should the technician perform NEXT?

A technician is upgrading the memory on an enterprise rackmount server. The system documentation explicitly specifies that the motherboard requires Registered DIMMs (RDIMMs) to handle high-density memory configurations. The technician accidentally installs Unbuffered DIMMs (UDIMMs) of the same DDR generation and speed rating. Which statement correctly explains why the server fails to complete Power-On Self-Test (POST)?

An IT technician is setting up new desktop workstations in a conference room. The deployment guidelines require video interfaces capable of natively carrying both high-definition digital video and multi-channel digital audio over a single cable connection to integrated monitor speakers. Which of the following display cable standards fulfill these requirements? (Select TWO.)

A technician is setting up a testing virtual machine (VM) on a desktop computer. The VM requires access to the Internet to download system updates, but it must share the physical host computer's single IP address and be masked from receiving direct, unsolicited incoming connections from the local physical network. Which virtual network interface configuration mode should the technician select?

A field technician is assembling a high-performance desktop workstation and reviewing the motherboard power connections prior to cable management. Which TWO of the following statements correctly describe standard motherboard power connectors and their operational roles?

A system administrator is troubleshooting a Windows workstation that fails to start up, displaying an error indicating that the Boot Configuration Data (BCD) file is missing or corrupted. The administrator boots the workstation using Windows installation media, opens the Command Prompt within the Windows Recovery Environment (WinRE), and needs to repair the boot configuration. Which TWO of the following bootrec utility commands should the administrator run to repair the Master Boot Record and rebuild the BCD store?

Match each enterprise cloud deployment scenario on the left with its corresponding cloud deployment model on the right.

An IT support technician is setting up a new fused deposition modeling (FDM) 3D printer. During the initial test print, the extruded filament fails to adhere to the heated build bed and gathers into a tangled mass of plastic around the print head nozzle. Which of the following maintenance or calibration procedures should the technician perform first to resolve this issue?

An IT technician is preparing to use a solvent-based aerosol contact cleaner to remove heavy residue and oxidation from circuit board connectors inside an industrial control cabinet. According to standard environmental safety protocols and Safety Data Sheets (SDS), which of the following safety precautions should the technician implement during this process? (Select TWO.)

An IT technician is troubleshooting a corporate mobile device where web browsing requests are being unexpectedly redirected to malicious external sites, accompanied by untrusted certificate warnings. Inspection of the device reveals an unauthorized configuration profile forcing web traffic through an unknown third-party proxy server. Which of the following actions should the technician perform FIRST to resolve the issue?

An IT technician is deploying a client-server financial application across multiple Windows 11 Pro workstations. The installation requires access to a centralized database server over the network and needs to store shared temporary cached data locally on each machine. Which of the following configuration actions should the technician perform to ensure proper application functionality for standard users? (Select TWO.)

An IT administrator is writing a Python (.py) script to automate system memory auditing across network workstations. The script imports a memory limit value from a text configuration file as "16", but when the script attempts to add 4 to this value, it throws a type error and fails to execute the calculation. Which scripting construct and method should the administrator use to resolve this issue?

A tier-2 support technician is performing targeted configuration tasks across several Windows workstations. Match each maintenance scenario on the left with the correct Windows Control Panel utility required to complete the task on the right.

A system integrator is calculating the power requirements for a video rendering workstation. The rated peak power draws for the selected system components are as follows:

- Processor (CPU): $140\text{ W}$
- Graphics Processing Unit (GPU): $310\text{ W}$
- Motherboard and RAM: $50\text{ W}$
- Solid-State Drives and Cooling Fans: $40\text{ W}$

To ensure stable operation under full workload and allow for component longevity, the specification mandates a minimum safety headroom of $20\%$ above the total peak power draw. What is the minimum power supply unit (PSU) wattage rating required to satisfy this specification?

An IT support technician is organizing preventive maintenance tasks across a company's varied printer fleet. Match each maintenance activity on the left with its corresponding printer technology on the right.

A desktop workstation used for video rendering unexpectedly shuts down completely during intensive tasks without displaying any prior system warnings or error screens. Pressing the power switch immediately after the shutdown produces no response. However, after the workstation sits idle for ten minutes, it powers back on normally until heavy rendering is initiated again. Which TWO of the following are the most likely causes of this behavior?

An organization recently upgraded all workstation computers to Windows 11 Enterprise 64-bit. However, the accounting department relies on a proprietary database client that only runs within a 32-bit Windows 7 environment. The organization wants to avoid buying dedicated legacy physical hardware while maintaining Windows 11 as the primary operating system on each user's desktop. Which of the following client-side virtualization purposes best addresses this requirement?

Match each macOS or Linux administrative utility/feature to its primary operating system function.
