A technician is troubleshooting a Windows 11 workstation where a graphic design application repeatedly crashes whenever a rendering task is initiated. In Event Viewer, the Application log records an Event ID 1000 entry identifying the faulting module as d3d11.dll. Which of the following command-line tools should the technician run FIRST to scan and repair this protected operating system file?

An IT security analyst is deploying a virtual machine (VM) on a workstation to analyze untrusted software binaries. The analyst needs to prevent the VM from communicating with the local physical network while ensuring that malicious processes within the guest OS cannot exhaust host physical hardware resources. Which of the following actions should the analyst take? (Select TWO.)

A desktop workstation was recently relocated from the Finance department subnet ($192.168.10.0/24$) to the Marketing department subnet ($192.168.20.0/24$). A technician manually configured the network adapter with a static IPv4 address of $192.168.20.45$, a subnet mask of $255.255.255.0$, a default gateway of $192.168.10.1$, and a preferred DNS server of $192.168.10.5$. The workstation can ping adjacent computers on the local $192.168.20.0/24$ network, but users report they cannot reach internal servers on other subnets or access external internet resources. Which of the following configuration changes will resolve the workstation's reachability issue?

An IT technician is preparing a newly imaged Windows workstation for deployment in a corporate environment. To ensure defense-in-depth and follow workstation hardening best practices, place the following security configuration steps in the correct operational sequence, from first to last.

A systems technician is servicing a Windows 11 Enterprise workstation controlling an automated warehouse sorting line. The system displays unusual pop-up advertisements, background network latency spikes, and unauthorized registry modifications. The technician has physically disconnected the network cable and disabled all wireless interfaces to isolate the machine. Which TWO of the following tasks must the technician perform NEXT before initiating the full system antimalware scan?

A desktop technician is setting up a client application to download incoming email from an legacy mail server using unencrypted Post Office Protocol v3 (POP3). Which default port number should be configured in the client settings?

A system administrator is troubleshooting a Windows 11 workstation that experiences severe performance degradation and frequent crashes of a CAD rendering tool during complex rendering tasks. Task Manager shows RAM usage at 96% with heavy disk paging, and Event Viewer shows periodic application failure logs. Which TWO of the following diagnostic actions should the technician perform to isolate the cause of the crashes and performance issues?

A tier-1 desktop technician is dispatched to handle an enterprise Windows 11 workstation that has been infected with rogue software generating persistent security alerts and attempting unauthorized network transmissions. Place the following remediation steps in the exact sequence required by the standard CompTIA 7-step malware removal procedure.

A network administrator is deploying a virtual machine (VM) on a desktop computer to run a network management service. The service requires the VM to obtain its own IP address directly from the physical network's DHCP server and be fully accessible by other physical devices on the local subnet. Which virtual network adapter mode should the administrator configure?

A systems technician is configuring security hardening settings on newly deployed Windows workstations used in a retail environment as point-of-sale terminals. To reduce the system's attack surface and prevent unauthorized automated execution of malicious files from USB flash drives, which of the following administrative actions should the technician perform?

An IT support technician is deploying networked smart HVAC controllers throughout a company's corporate office. The embedded operating systems on these controllers cannot support third-party endpoint security software, centralized domain joining, or local user credential management. Which of the following security practices should the technician implement to BEST secure these embedded systems against unauthorized network access?

A network administrator detects unauthorized outbound IRC traffic originating from a Windows 11 telemetry workstation located in a remote weather research facility. The administrator successfully disconnects the workstation's network interface and isolates the machine locally. Which action should be performed NEXT in accordance with the standard malware removal procedure before downloading signature updates via out-of-band media and running remediation scans?
