Question 161

Which Windows utility can be used to apply local group policy settings on a supported computer?

1. Disk Management
2. Local Group Policy Editor
3. Character Map
4. Resource Monitor

Correct Answer: 2

Explanation

Local Group Policy Editor allows administrators to configure many Windows settings related to security, user behavior, applications, and system functionality. It is commonly opened with the gpedit.msc command on editions that support it. Technicians can use policies to control settings such as password requirements, application behavior, and system restrictions. Group Policy changes should be made carefully because an incorrect setting can affect users or system functionality. Before modifying important policies, technicians should understand the existing configuration and follow organizational change-management procedures.

Question 162

Which Windows command displays the Resultant Set of Policy information applied to a user or computer?

1. gpresult
2. ipconfig
3. netstat
4. hostname

Correct Answer: 1

Explanation

The gpresult command displays information about Group Policy settings that have been applied to a Windows user or computer. It can help technicians determine whether a particular policy is actually being received when troubleshooting configuration problems. This is especially useful in environments where multiple policies may be applied from different sources. Technicians can use appropriate command options to produce more detailed information or reports. If a policy is not applying as expected, the technician can then investigate connectivity, policy scope, permissions, and update-related issues.

Question 163

Which Windows command can be used to display local user account information from the command line?

1. route
2. diskpart
3. net user
4. tracert

Correct Answer: 3

Explanation

The net user command is used to view and manage local Windows user accounts from the command line. A technician can use it to review account information and, with appropriate privileges, perform administrative tasks such as creating, modifying, or disabling accounts. This command can be useful when graphical administrative tools are unavailable or when troubleshooting requires command-line access. Technicians should verify the correct account before making changes because modifying or disabling the wrong account could prevent a legitimate user from accessing the system.

Question 164

A technician needs to mount, format, or manage disk partitions from a command-line environment. Which Windows utility is appropriate?

1. msconfig
2. diskpart
3. gpupdate
4. tasklist

Correct Answer: 2

Explanation

DiskPart is a Windows command-line utility used to manage disks, partitions, and volumes. It can perform powerful operations such as creating, deleting, formatting, selecting, and assigning volumes. Because DiskPart can permanently modify storage structures, technicians should verify the selected disk and partition before executing destructive commands. Incorrect commands can result in serious data loss. It is therefore important to confirm backups and carefully review command targets. DiskPart is especially useful when graphical disk-management tools are unavailable or when advanced storage operations are required.

Question 165

Which Windows command-line utility can repair the Windows component store and operating system image?

1. shutdown
2. dism
3. whoami
4. netstat

Correct Answer: 2

Explanation

DISM, or Deployment Image Servicing and Management, is used to service and repair Windows images and components. Technicians commonly use DISM when Windows system components are corrupted or when another repair utility cannot successfully resolve the problem. Depending on the situation, DISM can check the health of the Windows image and restore required components. It should be used carefully, particularly when working with advanced servicing options. Technicians should document the commands used and verify system functionality after completing the repair process.

Question 166

A Windows computer has corrupted system files. Which command can scan protected system files and attempt to repair them?

1. sfc /scannow
2. ping /repair
3. chkdsk /network
4. ipconfig /restore

Correct Answer: 1

Explanation

The sfc /scannow command scans protected Windows system files and attempts to replace corrupted or modified versions with valid copies. It is commonly used when Windows features behave unexpectedly, system components produce errors, or corruption is suspected. The scan can take some time, and the technician should allow it to complete before evaluating the results. If System File Checker cannot repair all detected problems, additional troubleshooting may be required, including servicing the Windows image. The technician should review the reported result before deciding on further action.

Question 167

Which Windows utility allows a technician to configure services that start automatically with the operating system?

1. Device Manager
2. Services console
3. Disk Cleanup
4. Snipping Tool

Correct Answer: 2

Explanation

The Windows Services console allows technicians to view and manage background services running on the operating system. Each service can have a startup type, such as automatic, manual, or disabled, depending on its purpose and configuration. A technician troubleshooting a failed application may need to verify whether a required service is running. Services should not be disabled simply because their names are unfamiliar. Changing essential services can prevent Windows or applications from functioning correctly, so technicians should confirm dependencies and document significant configuration changes.

Question 168

Which Windows tool is commonly used to view and modify entries in the Windows Registry?

1. Event Viewer
2. Registry Editor
3. Resource Monitor
4. Disk Management

Correct Answer: 2

Explanation

Registry Editor, commonly launched with regedit, provides access to the Windows Registry, which stores configuration information used by Windows and many applications. Technicians may use it to troubleshoot specific configuration problems when supported procedures require registry changes. Registry modifications should be performed cautiously because deleting or changing the wrong entry can cause application failures or even prevent Windows from operating correctly. Before making significant changes, technicians should create an appropriate backup or restore option and follow documented procedures rather than making random registry edits.

Question 169

Which Windows command can map a shared network folder to a drive letter from the command line?

1. net use
2. net user
3. nslookup
4. taskkill

Correct Answer: 1

Explanation

The net use command can establish and manage connections to shared network resources, including mapping a network share to a drive letter. This allows users and applications to access shared files through a familiar drive path. The technician should verify that the user has appropriate permissions and that the network share is available before troubleshooting the mapping itself. Credentials should be handled securely, and persistent mappings should only be configured when appropriate. Network connectivity, DNS resolution, and share permissions may also affect successful access.

Question 170

Which Linux command is commonly used to display currently running processes?

1. chmod
2. ps
3. mkdir
4. mount

Correct Answer: 2

Explanation

The ps command displays information about currently running processes on a Linux system. Technicians can use it to identify active processes, process identifiers, and other useful details depending on the command options selected. This information can assist with troubleshooting applications that consume excessive resources or fail to terminate correctly. Other utilities can provide continuously updated process information, but ps is a fundamental command for process inspection. Technicians should identify the correct process before terminating anything to avoid disrupting important system services.

Question 171

Which Linux command is used to display available and used disk space on mounted file systems?

1. free
2. du
3. df
4. top

Correct Answer: 3

Explanation

The df command reports available and used disk space for mounted file systems in Linux. It is useful when troubleshooting errors caused by insufficient storage, such as applications failing to write files or services stopping unexpectedly. Technicians can use appropriate options to display information in more readable units. The du command serves a different purpose by showing disk usage associated with files and directories. When a partition is nearly full, technicians should identify unnecessary data carefully and avoid deleting system files without verification.

Question 172

A Linux technician needs to identify which directory is consuming a large amount of storage. Which command is most appropriate?

1. du
2. who
3. uname
4. passwd

Correct Answer: 1

Explanation

The du command reports disk usage for files and directories, making it useful for locating storage consumption within a Linux file system. A technician can use it to determine which directories contain large amounts of data and then investigate those locations further. This differs from df, which reports available and used space for mounted file systems. When cleaning up storage, technicians should verify the purpose of files before deleting them. Important logs, application data, or configuration files may be required for system operation.

Question 173

Which Linux command is commonly used to change file and directory permissions?

1. chown
2. chmod
3. grep
4. cat

Correct Answer: 2

Explanation

The chmod command changes permissions assigned to Linux files and directories. These permissions control access for the owner, group, and other users. Technicians can use symbolic or numeric permission formats depending on the required configuration. Permissions should be assigned according to the user’s or application’s actual requirements rather than granting unrestricted access. Excessive permissions can expose sensitive data or allow unauthorized modifications. Before changing permissions on important system files, technicians should confirm ownership, existing access requirements, and the potential effect on applications or services.

Question 174

Which macOS feature is designed to prevent applications from unidentified or untrusted sources from running without appropriate user approval?

1. FileVault
2. Gatekeeper
3. Time Machine
4. Activity Monitor

Correct Answer: 2

Explanation

Gatekeeper is a macOS security feature that helps control whether applications from untrusted or unidentified sources can be opened. It works with other macOS security mechanisms to reduce the risk of users accidentally running potentially harmful software. When an application is blocked, users may receive a warning explaining the security concern. Technicians should verify the source and authenticity of software before bypassing security controls. Disabling protections simply to make an application run can increase security risks and should only be considered when justified by organizational procedures.

Question 175

A macOS user wants to see which application is consuming excessive CPU resources. Which utility should the technician use?

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

Correct Answer: 1

Explanation

Activity Monitor provides information about running processes and resource consumption on macOS. It can display CPU, memory, energy, disk, and network activity, helping technicians identify applications or processes that may be causing performance problems. If one process consistently consumes excessive resources, the technician can investigate the associated application and determine whether updates, configuration changes, or other troubleshooting steps are necessary. A process should not be terminated automatically simply because it uses resources, since some system processes legitimately require substantial CPU or memory.

Question 176

Which macOS feature can create backups of files and allow users to restore previous versions?

1. FileVault
2. Time Machine
3. Spotlight
4. Terminal

Correct Answer: 2

Explanation

Time Machine is macOS’s built-in backup feature and can automatically back up supported files to a configured backup destination. It can allow users to browse previous versions and restore files after accidental deletion or unwanted changes. A technician should verify that Time Machine backups are actually configured and completing successfully before relying on them for recovery. Backup availability should not be assumed merely because the feature exists. Important systems should also follow appropriate backup retention and verification practices based on organizational requirements.

Question 177

Which mobile security measure prevents unauthorized access when a smartphone is left unattended?

1. Screen lock
2. Public Wi-Fi
3. Automatic brightness
4. Airplane mode

Correct Answer: 1

Explanation

A screen lock protects a mobile device when it is unattended by requiring authentication before the device can be accessed. Depending on the device, authentication may use a PIN, password, pattern, fingerprint, or facial recognition. A strong screen-lock method reduces the risk of unauthorized access to messages, applications, accounts, and stored data. Technicians should also recommend reasonable automatic lock timing and security updates. Screen locking does not replace backups or other security controls, but it provides an important first layer of physical device protection.

Question 178

An employee loses a company-owned smartphone containing business information. Which capability can allow administrators to remove organizational data remotely?

1. Remote wipe
2. Screen rotation
3. Bluetooth pairing
4. Mobile hotspot

Correct Answer: 1

Explanation

Remote wipe allows authorized administrators to erase data from a lost or stolen managed device. Organizations may use mobile device management systems to enforce this capability and protect company information when a device is no longer under the user’s control. The exact behavior depends on the platform and management configuration. Before deploying remote wipe, organizations should establish policies covering ownership, authorization, privacy, and data recovery. A remote wipe can protect information, but it should be combined with strong authentication, encryption, device management, and reliable backups.

Question 179

A technician needs to provide remote assistance to a user’s computer. What should be obtained before starting the session?

1. User authorization
2. The user’s personal password
3. Permission to disable all security software
4. Permanent administrator access

Correct Answer: 1

Explanation

User authorization should be obtained before a technician begins a remote support session, according to organizational procedures. The user should understand what access is being requested and why it is necessary. Technicians should use approved remote-support tools and provide only the level of access required for the task. Sharing personal passwords or creating permanent administrator access is generally inappropriate. Remote sessions should also be documented according to company policy, particularly when configuration changes, software installation, or access to sensitive information occurs.

Question 180

Which professional practice helps ensure that a technician can review what was changed during a previous support incident?

1. Ignoring ticket details
2. Closing tickets without notes
3. Documenting actions in the ticket
4. Using undocumented personal procedures

Correct Answer: 3

Explanation

Documenting troubleshooting steps and changes in the support ticket creates a record that other technicians can review later. Useful documentation can include symptoms, diagnostic steps, findings, changes made, user communication, and the final resolution. Clear records reduce duplicated work and make future troubleshooting more efficient, especially when the same issue returns. Technicians should avoid including unnecessary sensitive information in tickets and should follow organizational documentation standards. Accurate ticketing also supports accountability, knowledge sharing, and continuity when multiple technicians handle the same system.
