\u00a0<\/strong><\/p>\n Which Windows utility can display detailed information about installed hardware and system components?<\/b><\/p>\n Correct Answer: 2<\/b><\/p>\n Explanation<\/b><\/p>\n System Information provides detailed information about a Windows computer’s hardware resources, components, software environment, and system configuration. Technicians can use it when investigating compatibility issues, identifying installed components, or documenting a workstation’s configuration. The utility can provide information such as processor details, memory, system model, drivers, and operating-system information. This makes it useful during troubleshooting without requiring the technician to physically open the computer. Technicians should verify important hardware details through reliable system information before ordering replacement components or changing configurations.<\/span><\/p>\n A user reports that Windows applications are running slowly. Which tool can help identify a process consuming excessive CPU resources?<\/b><\/p>\n Correct Answer: 3<\/b><\/p>\n Explanation<\/b><\/p>\n Task Manager can display running applications and processes along with resource usage such as CPU, memory, disk, and network activity. If a computer becomes slow, a technician can use these statistics to identify a process consuming an unusually large amount of system resources. The technician should first determine whether the process is legitimate before terminating it. Some Windows processes are essential for system operation. After identifying the responsible application, the technician can investigate updates, configuration problems, malware, or other causes instead of simply ending the process repeatedly.<\/span><\/p>\n Which Windows feature can prevent standard users from making certain administrative changes without approval?<\/b><\/p>\n Correct Answer: 1<\/b><\/p>\n Explanation<\/b><\/p>\n User Account Control, or UAC, helps prevent unauthorized or accidental administrative changes by requesting confirmation or administrative credentials when an action requires elevated privileges. It provides an additional security boundary between normal user activity and administrative operations. UAC does not replace antivirus software, firewall protection, or proper account management. Technicians should avoid disabling UAC merely to make troubleshooting easier because doing so reduces an important security control. Administrative tasks should be performed through approved elevation procedures while maintaining the principle of least privilege.<\/span><\/p>\n Which Windows command can show the routing table currently used by a computer?<\/b><\/p>\n Correct Answer: 2<\/b><\/p>\n Explanation<\/b><\/p>\n The <\/span>route print<\/span> command displays the computer’s IP routing table, including network destinations, gateways, interfaces, and metrics. This information can help technicians troubleshoot connectivity problems when traffic is being sent through an incorrect gateway or interface. A routing issue may affect access to specific networks while leaving local connectivity working normally. Technicians should compare the routing table with the expected network configuration before making changes. Incorrect manual routes can disrupt communication, so modifications should be performed only when justified and properly documented.<\/span><\/p>\n Which Linux command is commonly used to terminate a process by its process ID?<\/b><\/p>\n Correct Answer: 3<\/b><\/p>\n Explanation<\/b><\/p>\n The Linux <\/span>kill<\/span> command can send a signal to a process identified by its process ID, or PID. Technicians may use it when an application or process becomes unresponsive and cannot be closed normally. The default signal requests termination, while other signals can provide different behaviors. Administrators should verify the PID carefully before terminating a process because ending an essential system process may cause service interruption or instability. If possible, technicians should first use normal application or service controls before forcefully terminating a process.<\/span><\/p>\n Which Linux command can display the contents of a text file directly in the terminal?<\/b><\/p>\n Correct Answer: 1<\/b><\/p>\n Explanation<\/b><\/p>\n The Linux <\/span>cat<\/span> command can display the contents of text files directly in a terminal. It is useful for quickly reviewing configuration files, scripts, and small log files during troubleshooting. Technicians should be cautious when using it with very large files because the terminal can become difficult to navigate. For lengthy content, commands such as <\/span>less<\/span> may provide better control. When reviewing sensitive files, technicians should also follow organizational security procedures and avoid exposing confidential information through screenshots, copied output, or unauthorized remote sessions.<\/span><\/p>\n Which Linux utility can be used to display currently running processes in a continuously updating view?<\/b><\/p>\n Correct Answer: 2<\/b><\/p>\n Explanation<\/b><\/p>\n The Linux <\/span>top<\/span> utility provides a continuously updating view of running processes and system resource usage. It can display information such as CPU consumption, memory usage, process identifiers, and process states. Technicians can use this information to identify processes that are consuming unusually high resources or causing performance problems. Unlike a static process listing, <\/span>top<\/span> continuously refreshes its information, making it useful for observing changing workloads. A technician should investigate the identified process before terminating it, especially when it appears to be a critical system component.<\/span><\/p>\n Which macOS feature is primarily used to locate files, applications, settings, and other content quickly?<\/b><\/p>\n Correct Answer: 2<\/b><\/p>\n Explanation<\/b><\/p>\n Spotlight is macOS’s built-in search feature for locating files, applications, settings, documents, and other indexed information. Users can quickly search for content without manually navigating through multiple folders. Technicians can use Spotlight when helping users locate applications or files whose storage location is unknown. If Spotlight searches return incomplete results, indexing problems may need to be investigated. Search results should not be interpreted as evidence that a file exists in a particular location without verifying the actual item and its permissions.<\/span><\/p>\n Which macOS utility is useful for viewing system and application log messages?<\/b><\/p>\n Correct Answer: 1<\/b><\/p>\n Explanation<\/b><\/p>\n Console is a macOS utility that allows technicians to view system and application log information. Logs can provide useful evidence when investigating application crashes, service failures, authentication issues, and other system events. A technician should correlate log messages with the time the problem occurred rather than assuming every warning represents the root cause. Large log collections can contain many routine events. Effective troubleshooting involves identifying messages that correspond to the reported symptoms and checking whether the issue is reproducible after a specific change.<\/span><\/p>\n Which macOS feature is designed to restore files or recover system data from previous backups?<\/b><\/p>\n Correct Answer: 2<\/b><\/p>\n Explanation<\/b><\/p>\n Time Machine is macOS’s built-in backup solution and can maintain historical versions of files and other supported data. It allows users to recover files that were changed, deleted, or otherwise lost, provided suitable backups exist. Technicians should verify that backups are actually completing successfully rather than assuming that an enabled backup configuration guarantees recovery. Backup destinations should also have sufficient capacity and remain accessible. Important recovery procedures should be tested periodically because an untested backup cannot reliably demonstrate that required data can be restored.<\/span><\/p>\n Which security practice requires users to receive only the permissions necessary to perform their assigned duties?<\/b><\/p>\n Correct Answer: 2<\/b><\/p>\n Explanation<\/b><\/p>\n The principle of least privilege requires users and processes to receive only the permissions necessary to perform their legitimate tasks. Limiting privileges reduces the potential impact of compromised accounts, malicious software, and accidental changes. For example, a standard employee generally should not receive unrestricted administrative access when ordinary user permissions are sufficient. Technicians should review group memberships and elevated permissions periodically. Temporary administrative access should be granted only when necessary and removed afterward. Least privilege is an important security principle for workstations, servers, applications, and cloud environments.<\/span><\/p>\n An attacker sends a text message pretending to be a bank and asks the recipient to click a verification link. What type of attack is this?<\/b><\/p>\n Correct Answer: 2<\/b><\/p>\n Explanation<\/b><\/p>\n Smishing is a form of phishing that uses SMS or other text messaging services to deceive victims. Attackers may impersonate banks, delivery companies, employers, or other trusted organizations and encourage recipients to click malicious links or disclose credentials. Users should avoid opening unexpected links and should verify requests through official channels rather than using contact information provided in the suspicious message. Technicians can reduce the risk through security awareness training, endpoint protection, filtering, and clear procedures for reporting suspicious messages.<\/span><\/p>\n Which type of malware can replicate itself across networks without requiring users to manually execute an infected file?<\/b><\/p>\n Correct Answer: 1<\/b><\/p>\n Explanation<\/b><\/p>\n A worm is malware capable of self-replication and propagation, often spreading across networks by exploiting vulnerabilities or weaknesses in systems and services. Unlike traditional viruses, worms do not necessarily require a user to manually open an infected file to spread. A worm outbreak can consume network bandwidth, overload systems, and introduce additional malicious activity. Technicians should isolate affected systems, apply appropriate security updates, investigate the propagation method, and follow incident-response procedures. Restoring normal connectivity should occur only after the underlying threat has been addressed.<\/span><\/p>\n Which authentication factor is represented by a hardware security token?<\/b><\/p>\n Correct Answer: 4<\/b><\/p>\n Explanation<\/b><\/p>\n A hardware security token represents the authentication category of something you have because the user must possess a physical object to authenticate. Examples can include security keys and certain token devices. Authentication factors are commonly divided into categories such as something you know, something you have, and something you are. Combining multiple different factors provides multifactor authentication. Technicians should ensure that tokens are issued, registered, and recovered according to organizational procedures. Lost tokens should be reported promptly so appropriate access controls can be applied.<\/span><\/p>\n Which physical security control is designed to prevent an unauthorized person from entering by following closely behind an authorized person?<\/b><\/p>\n Correct Answer: 1<\/b><\/p>\n Explanation<\/b><\/p>\n A mantrap is a physical access-control arrangement that uses two interlocking doors or controlled entry points to help prevent unauthorized individuals from following an authorized person into a secured area. Typically, one door must close before the next can open. Mantraps are commonly used in locations requiring strong physical security, such as data centers and restricted facilities. They provide a physical control rather than a software-based security measure. Organizations may combine mantraps with badges, biometrics, surveillance cameras, and visitor-management procedures.<\/span><\/p>\n A technician receives a ticket stating that a user’s application stopped working after a recent update. What should the technician do before making changes?<\/b><\/p>\n Correct Answer: 3<\/b><\/p>\n Explanation<\/b><\/p>\n Before changing a system, the technician should gather relevant information about the symptoms, recent changes, error messages, affected users, and timing of the failure. Since the problem appeared after an update, that recent change is an important troubleshooting clue. Proper information gathering helps establish a baseline and prevents unnecessary modifications. The technician should document findings in the ticket and then test appropriate corrective actions. Avoiding premature changes also reduces the risk of making the original problem more difficult to diagnose.<\/span><\/p>\n Which backup type copies all selected data each time the backup is performed?<\/b><\/p>\n Correct Answer: 3<\/b><\/p>\n Explanation<\/b><\/p>\n A full backup copies all selected data during each backup operation. Because every backup contains the complete selected dataset, restoration can be simpler than restoring from a chain of incremental backups. However, full backups generally require more storage space and can take longer to complete. Organizations may combine full backups with other backup methods to balance storage requirements, backup duration, and recovery needs. Technicians should also verify that backups complete successfully and that stored backup data can actually be restored when required.<\/span><\/p>\n Which virtualization component allows multiple virtual machines to share the resources of one physical host?<\/b><\/p>\n Correct Answer: 1<\/b><\/p>\n Explanation<\/b><\/p>\n A hypervisor is the software or firmware layer responsible for creating and managing virtual machines on a physical host. It allocates resources such as processor time, memory, storage, and networking to virtual machines while maintaining separation between their environments. Virtualization allows multiple workloads to operate on one physical computer when sufficient resources are available. Technicians should monitor resource utilization because excessive allocation or an overloaded host can affect virtual machine performance. Proper isolation, access control, and backup procedures are also important in virtualized environments.<\/span><\/p>\n A user wants to install an application on an Android device.
