A tier 1 help desk technician is troubleshooting a Windows 11 client computer that cannot access internal intranet resources using domain names (such as http://intranet.company.local), although reaching resources via IP address works correctly. The technician verifies that the DHCP server was recently updated with new DNS server addresses, but the client system is still retaining outdated network parameters. Which of the following command sequences should the technician execute in an elevated Command Prompt to obtain the updated DNS server addresses from DHCP and clear stale host resolution entries?

A desktop technician is deploying computers for a newly established branch office. Corporate security policy mandates that all client endpoints must support Active Directory Domain Join, incoming Remote Desktop (RDP) hosting, and Local Group Policy Management (gpedit.msc). The workstations currently have Windows 11 Home installed. Which operating system edition upgrade is the minimum required to fulfill all specified technical and policy requirements?

A field technician is troubleshooting a Windows 11 workstation on a corporate network. The workstation can access public websites on the Internet, but it fails to connect to internal network shares using their hostnames (for example, `\\fileserver.corp.local`). Running `ipconfig /all` shows that the network adapter received a valid IPv4 address of $10.1.20.105$ and subnet mask $255.255.255.0$ via DHCP, but its DNS servers are manually specified as $1.1.1.1$ and $1.0.0.1$. Pinging internal resources by their local IP address ($10.1.20.10$) succeeds. Which of the following actions should the technician take to resolve the internal name resolution issue?

A network technician is diagnosing several network connectivity issues across different client workstations. Match each diagnostic symptom or command output on the left with its primary underlying network configuration cause on the right.

A network infrastructure technician is auditing cabling deployments across an enterprise campus facility. Match each network cable type and connector specification on the left to its correct physical characteristic or deployment requirement on the right.

A desktop technician receives a helpdesk ticket regarding a graphic design workstation that has suddenly suffered severe write latency. Upon opening the system storage utility, the technician notes that a two-drive software RAID 1 array configured for project files has entered a degraded state due to a S.M.A.R.T. attribute failure notification on drive 1. What is the most appropriate action for the technician to take to restore array fault tolerance?

A desktop support technician is troubleshooting a Windows 11 workstation experiencing persistent network stack corruption and invalid socket bindings that prevent all web traffic. Standard GUI troubleshooter fixes have failed. The technician opens an administrative Command Prompt to perform a complete CLI-based network stack reset and system reboot. Place the command execution steps in the correct operational sequence to resolve the issue.

Match each wired or wireless network troubleshooting symptom to its most likely underlying root cause.

A technician is setting up a newly connected LCD monitor for an office workstation. The user reports that text and desktop icons appear blurry and stretched, despite the monitor displaying normal colors and brightness. Upon reviewing the system settings, the technician notices that the operating system display resolution is set to $1280 \times 720$, while the monitor manufacturer lists a physical panel specification of $1920 \times 1080$. Which of the following is the BEST action to resolve the image quality issue?

A systems technician is configuring a workstation running Windows 11 Home edition. The technician attempts to open the Local Users and Groups MMC snap-in (lusrmgr.msc) to modify local group memberships, but receives an error message indicating that the snap-in cannot be used with this edition of Windows. Which of the following explains why this error occurs?

A desktop PC in a graphic design studio unexpectedly shuts down and refuses to power on normally following a localized electrical surge. When the technician presses the chassis power button, the power supply unit (PSU) fan spins for a fraction of a second and immediately shuts off with an audible click. The system will not attempt to spin up again on subsequent button presses until the AC power cord is unplugged and reinserted. Which TWO of the following diagnostic steps should the technician take to isolate the root cause? (Select TWO.)

A user working on a corporate network needs to manage offline network files and review synchronization status on their Windows computer. Which of the following tasks can be performed directly using the Sync Center Control Panel utility? (Select TWO.)

A network administrator is hardening the network settings on a fleet of Windows 11 Pro workstations. Corporate security policy dictates that clients must properly resolve short, single-label hostnames across multiple internal subdomains without relying on unauthenticated broadcast name resolution protocols if DNS queries fail. Which TWO configuration settings or administrative policies must be implemented on the Windows clients to satisfy these requirements?

A technician suspects that corrupted protected Windows system files are causing system instability on a desktop computer. Which command-line utility should the technician run from an elevated Command Prompt to scan all protected system files and immediately replace corrupted files with cached copies?

Place the administrative configuration steps in Performance Monitor (`perfmon.msc`) into the correct chronological order from first to last.

A systems administrator is configuring a critical line-of-business daemon operating as a background process on a Windows 11 Workstation. The organization requires that if the service process crashes, the operating system must automatically attempt to restart the service on the first failure, execute a custom PowerShell remediation script on the second failure, and trigger a computer reboot on any subsequent failures. Which administrative tool should the administrator use to configure these tiered failure response actions?

A technician is troubleshooting a mobile 2-in-1 convertible laptop equipped with an organic light-emitting diode (OLED) display. The system powers on, operating system audio plays, and an external monitor connected via HDMI displays video properly. However, the internal screen remains completely black.

A shipping warehouse technician receives a report that a high-volume monochrome laser printer is producing documents with faint, repeating double images (ghosting) of previously printed text farther down every page. The technician measures the distance between the top edge of the original text and the top edge of its faint ghost image, finding an exact repeating interval of $3.75\text{ inches}$ ($95\text{ mm}$). Specifications for the printer's internal rollers list the following circumferences:
