Question 341

Which Windows tool can display the status of services running on a computer?

1. Disk Management
2. Services
3. Character Map
4. Paint

Correct Answer: 2

Explanation

The Windows Services management console allows technicians to view and manage background services running on the operating system. Each service can have a startup type and current status, such as running or stopped. If an application depends on a particular service, a stopped or improperly configured service may cause functionality problems. Technicians should identify the purpose of a service before changing its configuration because disabling an essential service can affect Windows or installed applications. Service changes should follow organizational procedures and should be documented when they affect production systems.

Question 342

Which Windows command can display the currently logged-in user’s account information?

1. format
2. netstat
3. whoami
4. diskpart

Correct Answer: 3

Explanation

The whoami command identifies the account and security context under which the current command session is running. It can be especially useful when troubleshooting permissions because a technician may be working under a different account than expected. In domain environments, the output can help confirm the user or account context associated with the session. Technicians should verify account identity before performing administrative actions and should not use shared credentials simply to bypass permission problems. This supports accountability and the principle of least privilege during troubleshooting.

Question 343

Which Windows utility can help identify applications that are consuming excessive disk activity?

1. Resource Monitor
2. Notepad
3. Registry Editor
4. System Restore

Correct Answer: 1

Explanation

Resource Monitor provides detailed information about CPU, memory, disk, and network activity. Its disk section can help technicians identify processes generating significant read or write activity when a system experiences slow storage performance. This can be useful when Task Manager provides a general indication of high disk utilization but more detail is required. The technician should determine whether the activity is expected, such as a backup or update, before terminating a process. Resource Monitor can therefore help move troubleshooting from a general symptom toward a specific process or service.

Question 344

Which Windows feature can automatically maintain previous versions of user files for recovery?

1. Windows Sandbox
2. File History
3. Device Manager
4. Windows Firewall

Correct Answer: 2

Explanation

File History is a Windows feature that can automatically back up selected user files to an appropriate storage location and retain previous versions. It can help recover files that were accidentally modified, deleted, or corrupted. Technicians should verify that File History is configured correctly and that the backup destination is available. It should not be confused with System Restore, which primarily restores system configuration and certain operating-system components. Organizations should still maintain broader backup strategies when business requirements demand protection beyond selected user files.

Question 345

A Windows computer receives an IP address beginning with 169.254. What does this usually indicate?

1. Successful DNS registration
2. Active VPN connection
3. Automatic private IP addressing
4. Static public addressing

Correct Answer: 3

Explanation

An IPv4 address in the 169.254.0.0/16 range generally indicates that Windows assigned an Automatic Private IP Addressing address because the computer did not successfully obtain an address from a DHCP server. This can point to problems involving the network connection, DHCP service, wireless association, cabling, or network infrastructure. A technician should investigate connectivity to the network and DHCP availability rather than manually replacing the address immediately. Checking adapter status and using appropriate IP configuration commands can help identify the underlying cause.

Question 346

Which Windows command can clear cached DNS information from the local resolver?

1. hostname
2. ipconfig /flushdns
3. shutdown
4. route print

Correct Answer: 2

Explanation

The ipconfig /flushdns command clears the local DNS resolver cache in Windows. This can be useful when a computer continues using an outdated or incorrect DNS record after a website, server, or network resource has changed. Clearing the cache does not repair a DNS server that is unavailable or misconfigured; it simply removes locally cached entries so future lookups can obtain current information. Technicians should use this command as part of a broader DNS troubleshooting process when symptoms indicate possible stale local resolution data.

Question 347

Which command can test whether a hostname resolves to an IP address?

1. chkdsk
2. nslookup
3. taskkill
4. gpupdate

Correct Answer: 2

Explanation

The nslookup command is used to query DNS servers and determine how a hostname resolves to an IP address or other DNS information. It is useful when users can reach some network resources but cannot access a particular hostname. A technician can use the command to determine whether the problem is related to DNS resolution rather than basic network connectivity. If the name does not resolve correctly, the technician can investigate DNS server configuration, records, connectivity, or client settings. Results should be compared with expected DNS information.

Question 348

Which Windows utility can identify a scheduled task that runs automatically at a specific time?

1. Task Scheduler
2. Disk Management
3. System Information
4. Credential Manager

Correct Answer: 1

Explanation

Task Scheduler allows Windows to execute programs, scripts, and system actions according to defined triggers and conditions. Technicians can review scheduled tasks when investigating unexpected application launches, automated maintenance, recurring scripts, or delayed operations. Each task can contain triggers, actions, conditions, and security settings. Before disabling a suspicious or unfamiliar task, the technician should determine its purpose and verify whether it belongs to Windows or an approved application. Scheduled tasks can also be reviewed during security investigations when unexplained recurring activity is observed.

Question 349

Which Windows command can display the names of processes currently running on a system?

1. tracert
2. net use
3. tasklist
4. nslookup

Correct Answer: 3

Explanation

The tasklist command displays information about processes currently running in Windows. It can provide process names, process identifiers, and additional information depending on the selected options. Technicians can use it when investigating applications that appear to be running in the background or when identifying a process before terminating it with an appropriate command. Because some processes are essential to Windows, technicians should verify the process identity before taking action. Tasklist is particularly useful when graphical tools are unavailable or when troubleshooting through a command-line session.

Question 350

Which Windows command can terminate a process when normal application controls do not work?

1. taskkill
2. ipconfig
3. whoami
4. route

Correct Answer: 1

Explanation

The taskkill command can terminate a running Windows process when an application is unresponsive or cannot be closed through normal controls. A technician can target a process by its process ID or other supported criteria. Before terminating a process, the technician should confirm its identity and determine whether ending it could cause data loss or system instability. Unsaved application work may be lost when a process is forcefully terminated. Taskkill should therefore be used as a troubleshooting measure after safer application-level methods have been considered.

Question 351

Which Windows component stores configuration information used by the operating system and installed applications?

1. File Explorer
2. Registry
3. Task Manager
4. Clipboard

Correct Answer: 2

Explanation

The Windows Registry is a hierarchical database containing configuration information used by Windows and many installed applications. It can contain settings related to hardware, software, users, services, and system behavior. Technicians may use Registry Editor when troubleshooting specific configuration problems, but registry changes should be approached carefully. Incorrect modifications can cause applications or Windows components to malfunction. Before changing registry entries, technicians should identify the exact setting involved and follow approved procedures. Backups or restore options should be considered when significant registry modifications are necessary.

Question 352

Which Windows utility can manage disk partitions and assign drive letters?

1. Disk Management
2. Event Viewer
3. Task Scheduler
4. Performance Monitor

Correct Answer: 1

Explanation

Disk Management provides a graphical interface for managing disks, partitions, volumes, and drive letters in Windows. Technicians can use it to initialize supported disks, create or delete partitions, format volumes, and change drive-letter assignments when appropriate. Partition changes can affect stored data, so technicians should verify the selected disk and volume before performing destructive operations. Important data should be backed up before modifying partitions. Disk Management is particularly useful when a newly installed storage device is detected by Windows but does not yet have an accessible volume.

Question 353

Which Windows tool can monitor processor, memory, disk, and other performance counters over time?

1. Event Viewer
2. Performance Monitor
3. Device Manager
4. Disk Cleanup

Correct Answer: 2

Explanation

Performance Monitor allows technicians to collect and examine detailed performance information using configurable counters. It can monitor resources such as processor utilization, memory activity, disk performance, and network-related measurements over time. This makes it useful when a problem occurs intermittently and cannot be diagnosed from a single snapshot. Technicians can establish a baseline and compare it with measurements taken during a performance problem. The collected information can help determine whether a resource consistently reaches a bottleneck and whether further hardware or software investigation is necessary.

Question 354

Which Windows feature allows a technician to create an isolated environment for testing potentially unsafe applications?

1. Windows Sandbox
2. File History
3. BitLocker
4. Credential Manager

Correct Answer: 1

Explanation

Windows Sandbox provides a temporary isolated environment for running applications separately from the main operating system. It can be useful when a technician needs to examine software or files without directly exposing the primary Windows installation to potential changes. The environment is designed to be disposable, so changes made inside it do not normally persist after the sandbox is closed. Technicians should still follow organizational security policies and should not assume that isolation eliminates every possible risk. Sandbox availability also depends on supported Windows editions and hardware configuration.

Question 355

Which Linux command can display the amount of free and used memory?

1. grep
2. free
3. mv
4. chmod

Correct Answer: 2

Explanation

The Linux free command displays information about system memory usage, including total, used, available, and related memory statistics. It can help technicians determine whether a system is experiencing memory pressure. When an application appears slow, the technician can compare memory information with process data from tools such as top or ps. Memory reported as used should not automatically be considered a problem because Linux uses available memory for caching. Technicians should interpret the available memory and overall system behavior rather than relying on one value alone.

Question 356

Which Linux command can move a file from one directory to another?

1. cat
2. mv
3. du
4. uname

Correct Answer: 2

Explanation

The Linux mv command can move files or directories from one location to another and can also be used to rename them. Technicians should carefully verify both the source and destination paths before executing the command, particularly when working with administrative directories. Moving a file can affect applications that expect it to exist at a specific location. Appropriate permissions are also required. Before modifying important configuration files, technicians should preserve a backup when appropriate and confirm that the resulting file location matches the application’s or user’s requirements.

Question 357

Which macOS utility can provide information about running applications and their resource consumption?

1. Activity Monitor
2. Keychain Access
3. Migration Assistant
4. Disk Utility

Correct Answer: 1

Explanation

Activity Monitor provides macOS information about running processes and resource consumption. Technicians can use it to examine CPU, memory, energy, disk, and network activity when troubleshooting performance problems. If an application becomes unusually resource-intensive, Activity Monitor can help identify the process responsible. The technician should determine why the application is consuming resources before terminating it. Some processes are required by macOS, and ending them without understanding their purpose can cause instability or service interruptions. Activity Monitor is therefore both a diagnostic and monitoring tool.

Question 358

Which macOS utility can assist with transferring user accounts, files, and settings from another Mac or supported source?

1. Console
2. Migration Assistant
3. Gatekeeper
4. Spotlight

Correct Answer: 2

Explanation

Migration Assistant helps transfer user accounts, documents, applications, and certain settings from another Mac, Windows computer, or supported backup source. It can simplify the process of moving a user’s working environment to a replacement Mac. Before migration, technicians should verify that the source contains the required data and that sufficient storage is available on the destination. Important files should still have an independent backup because migration is not a substitute for a complete backup strategy. After migration, technicians should verify accounts, applications, permissions, and essential user data.

Question 359

Which security practice helps protect a workstation when the user leaves it unattended temporarily?

1. Disable the password
2. Leave applications open
3. Lock the screen
4. Share the account

Correct Answer: 3

Explanation

Locking the screen prevents unauthorized individuals from immediately accessing an unattended workstation while allowing the user’s session to remain active. A properly configured screen lock should require authentication before access is restored. Organizations may enforce automatic lock timers through security policies, especially on systems containing sensitive information. Users should develop the habit of locking their workstation whenever they step away. This simple physical-security measure complements other controls such as strong authentication, encryption, endpoint protection, and least-privilege access.

Question 360

A technician discovers that a user is repeatedly receiving suspicious browser redirects. What should the technician investigate?

1. Monitor brightness
2. Browser extensions and unwanted software
3. Printer alignment
4. Keyboard layout

Correct Answer: 2

Explanation

Repeated unexpected browser redirects can be associated with malicious or unwanted browser extensions, altered browser settings, adware, or other potentially unwanted software. The technician should review installed extensions, homepage and search settings, recently installed applications, and security alerts. Suspicious extensions should not simply be trusted because they appear in the browser interface. The technician should follow organizational malware-removal procedures and scan the system with approved security tools. Browser settings should be restored carefully, and the technician should document the findings and corrective actions.
