3. netstat
4. route

Correct Answer: 2

Explanation

The whoami command displays the username associated with the current Windows session. It is useful when a technician needs to confirm which account is being used, especially on systems with multiple local or domain accounts. Knowing the active identity can help when troubleshooting permission problems, application access, or administrative tasks. The command provides a quick verification without requiring the technician to open account-management tools. Technicians should always confirm the active account before making permission-related changes or performing actions that require elevated privileges.

Question 202

Which Windows utility can be used to configure startup options and diagnostic boot settings?

1. Disk Management
2. System Configuration
3. Event Viewer
4. Credential Manager

Correct Answer: 2

Explanation

System Configuration, commonly associated with msconfig, provides options for controlling startup behavior and accessing diagnostic configuration settings. Technicians can use it when troubleshooting services, startup applications, and boot-related problems. For example, selective startup can help determine whether a third-party service or startup component is contributing to a problem. Changes should be made carefully because disabling important services can create additional issues. After troubleshooting, technicians should restore appropriate startup settings and document significant changes made during the diagnostic process.

Question 203

Which Windows feature allows a technician to isolate potentially unsafe software in a temporary environment?

1. Credential Manager
2. Windows Sandbox
3. Disk Cleanup
4. File History

Correct Answer: 2

Explanation

Windows Sandbox provides a temporary isolated environment where supported applications and files can be tested without directly exposing the primary Windows installation to the same changes. When the Sandbox session is closed, its temporary environment is discarded. This can be useful when evaluating unfamiliar software or testing behavior in a controlled setting. Technicians should still follow organizational security procedures and avoid treating Sandbox as a complete replacement for malware analysis tools. Hardware virtualization support and compatible Windows editions may also be required.

Question 204

A technician needs to identify the Windows version, processor, installed memory, and other basic system details quickly. Which tool is appropriate?

1. Paint
2. System Information
3. Print Management
4. Task Scheduler

Correct Answer: 2

Explanation

System Information provides a centralized view of many hardware and operating system details. A technician can use it to identify information such as the processor, installed memory, Windows version, system model, BIOS information, and hardware resources. This can be useful before troubleshooting, upgrading hardware, or verifying compatibility with software requirements. Collecting accurate system information helps prevent incorrect assumptions. Technicians should record relevant details in the support ticket while avoiding unnecessary disclosure of sensitive configuration information.

Question 205

Which Windows command can release the IP address currently assigned by DHCP?

1. ipconfig /renew
2. ipconfig /flushdns
3. ipconfig /release
4. ipconfig /displaydns

Correct Answer: 3

Explanation

The ipconfig /release command releases the DHCP-assigned IP configuration for the selected network adapters. It is commonly used during network troubleshooting when a technician needs to remove the current lease before requesting a new configuration. It is often followed by ipconfig /renew when the goal is to obtain a fresh DHCP address. Releasing an address temporarily disconnects normal network communication for that adapter. Technicians should understand the expected effect before using the command on a user’s active workstation.

Question 206

Which Windows command requests a new DHCP configuration after an existing address has been released?

1. ipconfig /displaydns
2. ipconfig /renew
3. ipconfig /flushdns
4. ipconfig /all

Correct Answer: 2

Explanation

The ipconfig /renew command requests a new DHCP configuration from the network’s DHCP service. It is useful when a computer has lost connectivity because of an invalid or expired DHCP configuration. The command can be used after releasing the existing address or when troubleshooting an address-assignment problem. If the renewal fails, the technician should investigate the network connection, DHCP availability, adapter configuration, and network infrastructure. A successful renewal does not necessarily confirm that DNS or internet connectivity is functioning correctly.

Question 207

Which Windows utility can monitor system performance over time using counters for resources such as CPU and memory?

1. Disk Cleanup
2. Performance Monitor
3. Character Map
4. Remote Desktop

Correct Answer: 2

Explanation

Performance Monitor allows technicians to collect and examine detailed performance data using configurable counters. These counters can track resources such as processor utilization, memory activity, disk performance, and other system components. Unlike a quick snapshot from Task Manager, Performance Monitor can help identify trends and recurring performance problems over time. Technicians should select counters relevant to the reported symptoms rather than collecting unnecessary information. Recorded performance data can help establish whether resource usage is consistently abnormal or occurs only during specific workloads.

Question 208

Which Windows command can display the routing table used by the computer?

1. route print
2. hostname
3. tasklist
4. gpupdate

Correct Answer: 1

Explanation

The route print command displays the computer’s IP routing table. This table contains information used to determine where network traffic should be sent. Technicians can examine routing entries when troubleshooting communication problems involving multiple networks, gateways, or VPN connections. An incorrect route can cause traffic to use an unintended path or fail to reach its destination. Technicians should avoid modifying routes without understanding the network design because incorrect routing changes can disrupt connectivity. Existing entries should be reviewed before making any changes.

Question 209

Which Windows tool can be used to identify applications configured to launch automatically when a user signs in?

1. Disk Management
2. Device Manager
3. Task Manager
4. Event Viewer

Correct Answer: 3

Explanation

Task Manager includes a Startup section that allows technicians to review applications configured to launch when a user signs into Windows. It can also provide information about the startup impact of supported applications. Disabling unnecessary startup programs can sometimes improve boot and sign-in performance. However, technicians should verify the purpose of an application before disabling it because some startup components are required for security software, drivers, synchronization, or business applications. Changes should be documented when performed as part of a support procedure.

Question 210

A Windows user reports that the computer is extremely slow immediately after startup. Which area should the technician check first?

1. Wallpaper settings
2. Startup applications and processes
3. Screen resolution
4. Mouse sensitivity

Correct Answer: 2

Explanation

Startup applications and background processes can consume significant CPU, memory, disk, or network resources immediately after Windows starts. Task Manager can help identify applications with high startup impact or processes consuming excessive resources. The technician should compare resource usage with the user’s normal workload and determine whether unnecessary software is launching automatically. Malware, insufficient memory, storage problems, or system updates can also contribute to slow startup. Troubleshooting should proceed based on observed evidence rather than disabling applications randomly.

Question 211

Which Windows recovery environment option can provide access to command-line troubleshooting tools when Windows cannot boot normally?

1. Disk Cleanup
2. Windows Recovery Environment
3. File History
4. Print Management

Correct Answer: 2

Explanation

The Windows Recovery Environment provides recovery and troubleshooting options when Windows cannot start normally. It can provide access to tools such as Startup Repair, System Restore, command-line utilities, and other recovery features depending on the system configuration. Technicians may use these tools to diagnose boot failures or repair supported system problems. Recovery actions should be selected according to the symptoms because some options can modify system settings or restore previous configurations. Important data should be protected whenever possible before performing major recovery operations.

Question 212

Which Linux command changes the password for a user account?

1. passwd
2. mount
3. uname
4. less

Correct Answer: 1

Explanation

The passwd command is used in Linux to change or manage user passwords. A user can normally change their own password, while administrative privileges may be required when changing another user’s password or performing certain account-management tasks. Strong password practices are important because passwords protect access to local accounts and system resources. Technicians should follow organizational password policies and avoid recording passwords in insecure locations. If an account is suspected of compromise, password changes should be coordinated with other appropriate security measures.

Question 213

Which Linux command displays information about the currently logged-in users?

1. chmod
2. who
3. df
4. mkdir

Correct Answer: 2

Explanation

The who command displays information about users currently logged into a Linux system. It can help technicians determine whether other users have active sessions when performing maintenance or troubleshooting. Depending on the system and command options, information can include usernames, terminal sessions, login times, and connection details. This can be particularly useful on shared servers where multiple users may be connected simultaneously. Before terminating sessions or performing disruptive maintenance, technicians should verify active users and follow organizational procedures.

Question 214

Which Linux command displays basic information about the operating system and kernel?

1. top
2. uname
3. grep
4. touch

Correct Answer: 2

Explanation

The uname command displays basic information about the Linux operating system and kernel. With appropriate options, technicians can retrieve details such as the kernel name, kernel release, system architecture, and related information. This information can help determine whether software or drivers are compatible with the running environment. Technicians should collect system details before applying kernel-related changes or troubleshooting compatibility problems. Knowing the exact environment can prevent incorrect assumptions, especially when supporting systems with different Linux distributions and kernel versions.

Question 215

Which macOS utility can securely store passwords, certificates, and other authentication information?

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

Correct Answer: 2

Explanation

Keychain Access manages credentials and other protected information stored within macOS keychains. It can contain passwords, certificates, keys, and other authentication-related data used by applications and system services. Technicians may use it when troubleshooting authentication problems or reviewing stored credentials. Because keychain information can be highly sensitive, technicians should avoid exposing or copying credentials unnecessarily. Access should follow organizational security policies. Deleting stored credentials without understanding their purpose can also cause applications or services to repeatedly request authentication.

Question 216

Which macOS utility is primarily used to manage partitions, erase storage devices, and work with disk volumes?

1. Disk Utility
2. Activity Monitor
3. Keychain Access
4. Console

Correct Answer: 1

Explanation

Disk Utility provides macOS tools for managing storage devices, partitions, and volumes. Technicians can use it to inspect disks, erase supported volumes, create or modify partitions, and perform certain disk-repair operations. Because erasing or repartitioning a disk can permanently remove data, the technician must verify the selected device and confirm that required backups exist. Disk Utility should be used carefully when troubleshooting storage problems. The technician should also determine whether the problem is logical or hardware-related before performing destructive operations.

Question 217

A macOS application becomes unresponsive and does not close normally. Which action can force the application to terminate?

1. Open Keychain Access
2. Use Force Quit
3. Run Time Machine
4. Change the desktop wallpaper

Correct Answer: 2

Explanation

Force Quit allows a macOS user or technician to terminate an application that has stopped responding. It is useful when normal closing methods do not work and the application remains frozen. Before forcing an application to close, the technician should consider that unsaved work may be lost. If the same application repeatedly becomes unresponsive, additional troubleshooting should be performed instead of relying on Force Quit as a permanent solution. Application updates, system resources, corrupted preferences, or compatibility problems may contribute to recurring freezes.

Question 218

Which security practice helps protect a smartphone if it is lost by requiring authentication before access to stored information?

1. Disable automatic locking
2. Use a strong screen lock
3. Enable public file sharing
4. Remove all security updates

Correct Answer: 2

Explanation

A strong screen lock helps prevent unauthorized access when a smartphone is lost or stolen. Depending on the device, the lock can use a PIN, password, pattern, fingerprint, or facial recognition. Automatic locking after a reasonable period further reduces exposure when the device is left unattended. Screen locking should be combined with encryption, current security updates, secure application practices, and remote-management capabilities where appropriate. Users should avoid weak or easily guessed authentication methods because a screen lock is only effective when its credentials are adequately protected.

Question 219

Which mobile device management capability allows an organization to enforce security settings across company-owned smartphones?

1. MDM policy enforcement
2. Screen brightness control
3. Bluetooth discovery
4. Personal hotspot sharing

Correct Answer: 1

Explanation

Mobile device management, or MDM, allows organizations to centrally manage supported mobile devices and enforce security or configuration policies. Administrators can use MDM to apply requirements such as screen locks, encryption, application restrictions, device enrollment, and remote actions. Centralized management provides more consistent security than relying entirely on individual users to configure devices manually. Organizations should establish appropriate policies before enrollment and clearly define which data and actions administrators can control. MDM settings should balance organizational security requirements with applicable privacy and usage policies.

Question 220

A technician discovers an unknown USB flash drive in a company parking area. What should the technician do?

1. Plug it into a workstation to identify the owner
2. Format it immediately
3. Follow the organization’s security or incident-reporting procedure
4. Copy its files to a personal computer

Correct Answer: 3

Explanation

An unknown USB drive should not be connected to a company computer because it could contain malware or other malicious content. The technician should follow the organization’s security or incident-reporting procedure and allow authorized personnel to handle the device. This approach reduces the risk of introducing malware into the corporate environment. Technicians should never inspect suspicious removable media on production systems merely to determine its contents. Proper handling, documentation, and escalation allow the organization to investigate the device safely while preserving relevant evidence.
