Task Manager shows the disk at nearly 100% utilization, but CPU and memory usage are moderate. Which issue should the technician investigate first?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> Storage performance or a process generating excessive disk I\/O<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>2.<\/b><span style=\"font-weight: 400;\"> Screen resolution<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>3.<\/b><span style=\"font-weight: 400;\"> DNS configuration<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>4.<\/b><span style=\"font-weight: 400;\"> Local account password age<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 1<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">When disk utilization is consistently near 100% while CPU and memory remain moderate, the storage subsystem or a process generating heavy disk activity is a likely bottleneck. The technician should identify which process is using the disk, then determine whether the activity is expected. Windows Update, antivirus scans, indexing, synchronization software, excessive paging, a failing drive, or a poorly behaving application can all cause high disk I\/O. Screen resolution, DNS configuration, and password age do not normally explain local storage saturation. Task Manager and Resource Monitor can help isolate the process. If hardware failure is suspected, the technician should also review SMART information where available, event logs, and manufacturer diagnostics before replacing the drive.<\/span><\/p>\n<p><b>Question 262.<\/b><\/p>\n<p><b>Which Windows utility provides more detailed real-time information about CPU, memory, disk, and network activity than the basic Task Manager view?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> Disk Cleanup<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>2.<\/b><span style=\"font-weight: 400;\"> Resource Monitor<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>3.<\/b><span style=\"font-weight: 400;\"> File History<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>4.<\/b><span style=\"font-weight: 400;\"> System Restore<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 2<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Resource Monitor provides detailed real-time information about system resource use and can show which processes are consuming CPU, memory, disk, and network resources. It is especially useful when Task Manager indicates a general bottleneck but the technician needs more granular detail, such as which files a process is reading or which network connections it is using. Disk Cleanup removes unnecessary files, File History protects user data, and System Restore rolls back selected system settings. Resource Monitor is a diagnostic tool rather than a repair utility, so the technician should use its information to identify the underlying process or component before deciding on a corrective action.<\/span><\/p>\n<p><b>Question 263.<\/b><\/p>\n<p><b>A technician suspects that a Windows application is causing unusually high network traffic. Which tool can help identify the process and its active network connections?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> Disk Management<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>2.<\/b><span style=\"font-weight: 400;\"> Local Security Policy<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>3.<\/b><span style=\"font-weight: 400;\"> Resource Monitor<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>4.<\/b><span style=\"font-weight: 400;\"> File Explorer Options<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 3<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Resource Monitor can display network utilization by process and show TCP connections, listening ports, and network activity. This makes it useful when a technician suspects that a particular application is consuming excessive bandwidth or connecting to unexpected systems. Disk Management handles storage volumes, Local Security Policy controls security settings, and File Explorer Options changes file display behavior. The technician should determine whether the traffic is legitimate before terminating the process. High network usage might come from cloud synchronization, software updates, backups, malware, or a normal business application. If suspicious connections are observed, the workstation may require security investigation and possible isolation.<\/span><\/p>\n<p><b>Question 264.<\/b><\/p>\n<p><b>Which Windows utility provides a graphical overview of historical system stability and records critical events over time?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> Device Manager<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>2.<\/b><span style=\"font-weight: 400;\"> Disk Cleanup<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>3.<\/b><span style=\"font-weight: 400;\"> Windows Sandbox<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>4.<\/b><span style=\"font-weight: 400;\"> Reliability Monitor<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 4<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Reliability Monitor provides a timeline of system stability and records application failures, Windows failures, hardware errors, updates, and other significant events. It assigns a stability index and can help technicians correlate a problem with a recent software or driver installation. Device Manager focuses on hardware and drivers, Disk Cleanup removes unnecessary files, and Windows Sandbox creates an isolated temporary environment. Reliability Monitor is particularly useful when the problem is intermittent or started recently because it gives a concise historical view. Once a suspicious event is identified, the technician can use Event Viewer or other tools for more detailed analysis before making configuration changes.<\/span><\/p>\n<p><b>Question 265.<\/b><\/p>\n<p><b>A user reports that a Windows computer occasionally freezes. Which log should the technician review for operating-system and driver-related errors?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> System log in Event Viewer<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>2.<\/b><span style=\"font-weight: 400;\"> Browser history<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>3.<\/b><span style=\"font-weight: 400;\"> File History<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>4.<\/b><span style=\"font-weight: 400;\"> Recycle Bin<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 1<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">The System log in Event Viewer records events generated by Windows system components, drivers, and services. It is a useful place to investigate freezes, unexpected shutdowns, driver failures, service errors, and hardware-related warnings. Browser history tracks web activity, File History protects versions of user files, and the Recycle Bin temporarily stores deleted files. When troubleshooting intermittent freezing, the technician should look for events occurring at the same time as the reported symptom and compare them with recent driver, software, or hardware changes. Event logs are evidence and should not be cleared before the cause is understood.<\/span><\/p>\n<p><b>Question 266.<\/b><\/p>\n<p><b>Which Windows utility can be used to configure whether a service starts automatically when the system boots?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> Task Manager only<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>2.<\/b><span style=\"font-weight: 400;\"> Services<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>3.<\/b><span style=\"font-weight: 400;\"> Disk Management<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>4.<\/b><span style=\"font-weight: 400;\"> File History<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 2<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">The Services management console allows technicians to start, stop, pause, and configure Windows services. Startup types can include Automatic, Manual, and Disabled, depending on the service. If an application depends on a service that is not starting with Windows, reviewing the service configuration can help identify the problem. Task Manager can display services, but the Services console provides more complete management options. Disk Management handles storage, and File History protects user files. Technicians should understand service dependencies before changing startup settings because disabling a required service can break applications or core Windows functionality.<\/span><\/p>\n<p><b>Question 267.<\/b><\/p>\n<p><b>A user needs a program to run every weekday at 7:00 AM automatically. Which Windows utility should the technician configure?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> Device Manager<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>2.<\/b><span style=\"font-weight: 400;\"> System Restore<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>3.<\/b><span style=\"font-weight: 400;\"> Task Scheduler<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>4.<\/b><span style=\"font-weight: 400;\"> BitLocker<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 3<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Task Scheduler allows programs, scripts, or other actions to run automatically based on triggers. A technician can create a trigger for weekdays at 7:00 AM and specify the application or script to run. Other triggers can include startup, logon, or specific system events. Device Manager handles hardware, System Restore rolls back selected system changes, and BitLocker encrypts storage volumes. Scheduled tasks should be configured with the correct user context and permissions, especially if they need to run when no user is signed in. The technician should test the task after creation to confirm that it runs successfully under the intended conditions.<\/span><\/p>\n<p><b>Question 268.<\/b><\/p>\n<p><b>Which Windows command can list currently running processes and their process IDs from the command line?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> nslookup<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>2.<\/b><span style=\"font-weight: 400;\"> gpupdate<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>3.<\/b><span style=\"font-weight: 400;\"> route print<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>4.<\/b><span style=\"font-weight: 400;\"> tasklist<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 4<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">The <\/span><span style=\"font-weight: 400;\">tasklist<\/span><span style=\"font-weight: 400;\"> command displays processes running on a Windows computer and includes process IDs, session information, and memory usage. It is useful for command-line troubleshooting, scripting, or remote support. Once a process ID is identified, the technician may use other tools, such as <\/span><span style=\"font-weight: 400;\">taskkill<\/span><span style=\"font-weight: 400;\">, to stop the process when appropriate. <\/span><span style=\"font-weight: 400;\">nslookup<\/span><span style=\"font-weight: 400;\"> queries DNS, <\/span><span style=\"font-weight: 400;\">gpupdate<\/span><span style=\"font-weight: 400;\"> refreshes Group Policy, and <\/span><span style=\"font-weight: 400;\">route print<\/span><span style=\"font-weight: 400;\"> displays the routing table. A technician should not terminate an unfamiliar process simply because it is consuming resources; the process should first be identified and its purpose understood to avoid disrupting system services or security software.<\/span><\/p>\n<p><b>Question 269.<\/b><\/p>\n<p><b>Which Windows command is used to forcefully terminate an unresponsive process when the process ID is known?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> taskkill<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>2.<\/b><span style=\"font-weight: 400;\"> ipconfig<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>3.<\/b><span style=\"font-weight: 400;\"> hostname<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>4.<\/b><span style=\"font-weight: 400;\"> chkdsk<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 1<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">The <\/span><span style=\"font-weight: 400;\">taskkill<\/span><span style=\"font-weight: 400;\"> command terminates a Windows process by process ID or image name. Appropriate switches can be used when a process does not respond to normal close requests. This is useful in command-line environments or remote support sessions. <\/span><span style=\"font-weight: 400;\">ipconfig<\/span><span style=\"font-weight: 400;\"> displays network settings, <\/span><span style=\"font-weight: 400;\">hostname<\/span><span style=\"font-weight: 400;\"> displays the local computer name, and <\/span><span style=\"font-weight: 400;\">chkdsk<\/span><span style=\"font-weight: 400;\"> checks disks and file systems. Forcefully terminating a process can cause unsaved data to be lost, so the technician should attempt a normal shutdown first when possible. Critical system processes should not be terminated unless the technician understands the consequences.<\/span><\/p>\n<p><b>Question 270.<\/b><\/p>\n<p><b>A workstation cannot connect to a network share by server name, but it can connect successfully by IP address.

DNS translates hostnames into IP addresses, so the technician should verify DNS server settings, test the name with <\/span><span style=\"font-weight: 400;\">nslookup<\/span><span style=\"font-weight: 400;\">, and check whether the appropriate DNS record exists. DHCP provides dynamic network configuration but is less likely if the system already has valid IP connectivity. BitLocker encrypts storage, and the Print Spooler manages printing. Troubleshooting should isolate name resolution from general connectivity before changes are made to unrelated network settings.<\/span><\/p>\n<p><b>Question 271.<\/b><\/p>\n<p><b>Which Windows command queries a DNS server and can help confirm whether a hostname resolves to the expected address?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> tasklist<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>2.<\/b><span style=\"font-weight: 400;\"> sfc<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>3.<\/b><span style=\"font-weight: 400;\"> nslookup<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>4.<\/b><span style=\"font-weight: 400;\"> format<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 3<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">The <\/span><span style=\"font-weight: 400;\">nslookup<\/span><span style=\"font-weight: 400;\"> command queries DNS and displays resolution information for hostnames or IP addresses.

Modern ransomware attacks may also steal data before encryption and threaten public release. Adware focuses on unwanted advertisements, spyware collects information, and rootkits attempt to hide malicious activity or maintain stealthy privileged access. Defenses include patching, endpoint protection, least privilege, MFA, network segmentation, and reliable backups that are isolated or otherwise protected from the same attack. If ransomware is suspected, affected systems should be isolated quickly and the organization&#8217;s incident-response procedures followed.<\/span><\/p>\n<p><b>Question 277.<\/b><\/p>\n<p><b>Which malware type is designed primarily to secretly collect information about a user or system?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> Spyware<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>2.<\/b><span style=\"font-weight: 400;\"> Worm<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>3.<\/b><span style=\"font-weight: 400;\"> Logic bomb<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>4.<\/b><span style=\"font-weight: 400;\"> Ransomware<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 1<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Spyware is designed to collect information without appropriate authorization. It may track browsing activity, gather system information, capture credentials, or transmit sensitive data to an attacker. A worm focuses on self-propagation, a logic bomb activates when a predefined condition occurs, and ransomware denies access to systems or data. Spyware may be bundled with seemingly legitimate software or installed through malicious websites and attachments. Defenses include endpoint security, software updates, least privilege, browser protections, and user awareness. Suspected spyware should be handled through a controlled malware-remediation process rather than simply deleting one visible program and assuming the system is clean.<\/span><\/p>\n<p><b>Question 278.<\/b><\/p>\n<p><b>Which social-engineering attack uses a fraudulent telephone call to obtain passwords or one-time authentication codes?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> Smishing<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>2.<\/b><span style=\"font-weight: 400;\"> Vishing<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>3.<\/b><span style=\"font-weight: 400;\"> Tailgating<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>4.<\/b><span style=\"font-weight: 400;\"> Shoulder surfing<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 2<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Vishing is voice-based phishing. Attackers may impersonate technical support, banks, government agencies, or other trusted entities and pressure victims to reveal passwords, MFA codes, payment information, or remote-access credentials. Smishing uses text messages, tailgating is a physical access technique, and shoulder surfing involves visually observing confidential information. Users should independently verify unsolicited calls through known contact methods and should never provide passwords or one-time authentication codes to unexpected callers. Security-awareness training is essential because social engineering targets human trust rather than a purely technical vulnerability.<\/span><\/p>\n<p><b>Question 279.<\/b><\/p>\n<p><b>Which physical security control is designed to prevent an unauthorized person from following an authorized employee through a secured entrance?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> Privacy filter<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>2.<\/b><span style=\"font-weight: 400;\"> Cable lock<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>3.<\/b><span style=\"font-weight: 400;\"> Mantrap<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>4.<\/b><span style=\"font-weight: 400;\"> UPS<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 3<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">A mantrap uses two controlled doors to limit passage through a secure entrance, generally allowing one person to authenticate and pass through at a time. This can reduce tailgating and piggybacking by making it harder for an unauthorized person to follow an employee into a protected area. A privacy filter protects displayed information, a cable lock helps deter device theft, and a UPS provides electrical backup power. Mantraps are often used in data centers and other high-security facilities. Physical access controls should be combined with badges, cameras, visitor procedures, and employee awareness for stronger protection.<\/span><\/p>\n<p><b>Question 280.<\/b><\/p>\n<p><b>A technician has implemented a solution, verified full system functionality, and confirmed the user can work normally.

The technician should record the original symptoms, diagnostic steps, identified cause when known, corrective action, test results, and any preventive recommendations. This creates a useful support history, improves knowledge sharing, assists with recurring problems, and supports accountability. Deleting logs can remove valuable evidence, disabling updates weakens security, and making unrelated changes introduces unnecessary risk. A properly documented ticket provides a clear record for future technicians and allows the issue to be closed professionally once the user confirms normal operation.<\/span><\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>View Full CompTIA A+ 220-1102 Exam Dumps and Practice Test Dumps &nbsp; Question 261.
