A field technician is upgrading the system memory on a high-performance desktop workstation that supports dual-channel DDR4 memory architecture. The motherboard features four memory slots labeled Slot 1, Slot 2, Slot 3, and Slot 4, organized into two separate memory channels (Channel A: Slots 1 & 2; Channel B: Slots 3 & 4). Which TWO of the following configurations or requirements must be met to ensure the system operates in dual-channel mode? (Select TWO.)

An IT technician is auditing the wireless security of a small retail store's network. The store uses a SOHO wireless router configured with WPA2-Personal. During a security assessment, the technician discovers that an attacker parked outside could exploit a feature on the router to crack the network passphrase within a few hours by brute-forcing an eight-digit PIN, regardless of how long or complex the WPA2 passphrase is. Which of the following actions should the technician take to eliminate this vulnerability?

A software company hosts its software testing environment on infrastructure provided by a third-party vendor over the internet. Physical hardware resources are pooled and dynamically shared among multiple unrelated customer organizations to maintain low operational costs, though each tenant's virtual machines remain logically isolated. Which of the following cloud deployment models does this environment represent?

A mobile technician is responding to an alert indicating that a corporate smartphone has been compromised via an unapproved mobile configuration profile, causing unauthorized background data exfiltration. Place the standard incident response and remediation steps in the correct chronological order from first action to final resolution.

A system administrator reviewing environmental monitoring logs for a primary server room notes that the relative humidity (RH) has dropped to 18%. Which of the following potential hazards should the administrator address IMMEDIATELY to prevent equipment damage?

A helpdesk technician is troubleshooting user permission and account restrictions on a Windows 11 workstation following an Active Directory domain policy modification. The technician needs to view a summary report of the Resultant Set of Policy (RSoP) directly within the command prompt to verify which specific Group Policy Objects (GPOs) and security groups are active for the currently logged-in user. Which of the following commands should the technician execute?

A systems technician is configuring a video editing workstation. The peak power requirements for the hardware components are as follows:

- Central Processing Unit (CPU): $105\text{ W}$
- Two dedicated PCI Express capture cards: $75\text{ W}$ each
- Motherboard, system RAM, and active cooling fans combined: $85\text{ W}$

To prevent system instability and maintain PSU power efficiency, IT policy dictates incorporating a $25\%$ safety headroom buffer above the total peak component power draw. What is the minimum recommended power supply unit (PSU) output rating, in Watts ($W$), required for this build?

An IT support technician is reviewing the electrophotographic (EP) printing cycle to troubleshoot image quality issues on a office laser printer. Arrange the following EP laser printing steps in the correct chronological order from first to last.

A technician attempts to install a RAM upgrade in a laptop, but notices that the new memory module is physically too long to fit into the motherboard's memory slot. Which of the following best explains why the module does not fit?

A desktop support technician is working with a developer who needs to enable Internet Information Services (IIS) on a local Windows 11 Pro workstation to host and test a web application locally. Which Control Panel applet provides access to activate this built-in operating system component?

A Linux technician needs to adjust access permissions for an executable deployment script named deploy.sh located in a shared directory. The requirements specify that the file owner must have read, write, and execute permissions, members of the assigned group must have read and execute permissions only, and all other users must have no access permissions. Which command should the technician execute to assign these permissions?

An IT administrator is writing an automated maintenance script to check the connectivity of mapped network drives and append the audit results to a centralized log file. Which of the following represents the correct logical sequence of execution for these scripting steps from first to last?

A technician is installing an M.2 solid-state drive into an M.2 connector on a motherboard. The motherboard documentation specifies that this particular M.2 slot is wired internally for the SATA bus protocol only. If the technician installs a PCIe-only NVMe M.2 drive into this slot, which of the following will occur?

An IT technician is configuring data storage policies and access permissions for an organization that handles both patient intake appointments and billing payment transactions. Which of the following compliance actions directly adhere to the regulatory mandates of the Payment Card Industry Data Security Standard (PCI-DSS) and Health Insurance Portability and Accountability Act (HIPAA)? (Select TWO.)

A user reports that a business workstation turns on, but the monitor remains blank and no initial POST beep is emitted. The system power LED illuminates solid and internal chassis fans run continuously at full speed. A diagnostic POST card attached to the motherboard displays a code corresponding to an early memory initialization failure. Which of the following actions should the technician take FIRST?

A desktop technician is configuring a workstation to output to a high-resolution display requiring a $3840 \times 2160$ resolution at $60\text{ Hz}$ along with multi-channel digital audio. Which of the following cable types natively support transmitting both the digital video signal at this resolution and embedded multi-channel digital audio over a single cable connection without additional adapters? (Select TWO.)

A network security administrator is standardizing wireless authentication and encryption technologies across a corporate enterprise network. Match each wireless security control or authentication protocol on the left with its primary operational requirement or technical characteristic on the right.

A systems administrator is configuring an automated script to deploy a standardized software package across multiple enterprise workstations using Windows Installer (msiexec.exe). The deployment must execute in the background without displaying any graphical interface or requiring user interaction. Which of the following switches should the administrator append to the command line to ensure a fully quiet installation?

A system technician is reviewing hardware specifications to upgrade enterprise desktop computers from DDR4 to DDR5 memory. The technician notes that DDR5 memory modules move voltage regulation from the motherboard directly onto the memory module using an onboard Power Management Integrated Circuit (PMIC). Which of the following is a primary operational advantage of including an onboard PMIC on DDR5 RAM modules?

A cybersecurity engineer is deploying a high-security hypervisor host dedicated to running untrusted software applications inside virtual machines (VMs). The architecture requires that guest VMs can exchange diagnostic data with one another across a dedicated virtual network, but must be completely isolated from the host's physical network interface card (NIC) and external networks. Additionally, the administrator must safeguard the underlying physical host against Denial of Service (DoS) conditions caused by guest VM resource exhaustion. Which TWO configuration actions should the administrator implement to satisfy these security and networking requirements? (Select TWO.)
