Question 61

Which Windows utility can be used to identify applications that consume excessive memory or CPU resources?

1. Disk Management
2. Task Manager
3. Registry Editor
4. Device Manager

Correct Answer: 2

Explanation

Task Manager provides real-time information about processes and system resource usage, including CPU, memory, disk, network, and GPU activity. A technician can sort the process list by a resource category to identify applications consuming unusually high amounts of system resources. This is useful when investigating slow performance, application freezes, or high resource utilization. Task Manager can also show startup applications and services, providing additional information that can help identify why a Windows computer becomes slow during normal operation.

Question 62

A Windows computer has a valid IP address but cannot access websites by domain name. Which service should the technician investigate?

1. DHCP
2. DNS
3. SMB
4. FTP

Correct Answer: 2

Explanation

DNS translates human-readable domain names into IP addresses. If a computer has a valid IP address but cannot access websites using domain names, DNS configuration or availability should be investigated. A technician can use nslookup to test name resolution and determine which DNS server responds to queries. The technician should also verify the configured DNS server addresses and network connectivity. A system may successfully communicate with an IP address while still being unable to resolve hostnames, making DNS an important troubleshooting point.

Question 63

Which Windows command can be used to display detailed information about the computer’s network adapters and IP configuration?

1. ipconfig /all
2. tasklist
3. gpupdate
4. shutdown

Correct Answer: 1

Explanation

The ipconfig /all command provides detailed TCP/IP configuration information for network adapters. The output can include the adapter’s physical address, DHCP status, IPv4 and IPv6 information, subnet mask, default gateway, DNS servers, and lease information. Technicians commonly use this command when troubleshooting network connectivity or verifying whether a computer received the expected configuration from DHCP. Comparing the output with the organization’s network configuration can help identify incorrect addressing, gateway, or DNS settings.

Question 64

Which Windows feature allows users to search for and manage installed applications through a graphical interface?

1. Apps and Features
2. Event Viewer
3. Disk Management
4. Computer Management

Correct Answer: 1

Explanation

Windows provides application-management interfaces that allow users and technicians to view installed applications and, depending on the application, modify, repair, or uninstall them. These interfaces are useful when removing unwanted software or troubleshooting an application that is malfunctioning. A technician should verify the application being removed before proceeding because some components may be shared by other programs. For persistent application problems, repair or reinstall options may be preferable to immediately deleting associated files manually.

Question 65

A technician suspects corrupted Windows system files after repeated application errors. Which command should be attempted?

1. tracert
2. sfc /scannow
3. netstat
4. hostname

Correct Answer: 2

Explanation

The sfc /scannow command scans protected Windows system files and attempts to replace corrupted versions with valid copies. It is useful when Windows components behave unexpectedly or system file corruption is suspected. The scan may take some time depending on system performance and storage conditions. If SFC cannot resolve the issue, additional Windows servicing and recovery tools may be appropriate. Technicians should review the resulting messages and logs rather than assuming that running the command automatically fixes every operating system problem.

Question 66

Which Windows feature can automatically restore files from previous versions when configured appropriately?

1. File History
2. Device Manager
3. Windows Defender Firewall
4. Disk Cleanup

Correct Answer: 1

Explanation

File History is a Windows backup feature designed to preserve versions of personal files when configured with an appropriate backup location. It can allow users to recover earlier versions of supported files after accidental modification or deletion. File History should not be confused with System Restore, which focuses on system configuration and certain operating system components. Technicians should verify that File History is enabled and that the backup destination is accessible before assuming previous file versions are available.

Question 67

A user cannot install an application because Windows reports that administrative privileges are required. What should the technician verify?

1. The user’s permission level and installation requirements
2. The monitor’s refresh rate
3. The keyboard layout only
4. The printer paper size

Correct Answer: 1

Explanation

Some applications require administrative privileges to install because they modify protected system locations, services, drivers, or registry settings. The technician should verify the user’s account permissions and determine whether the software installation requires elevation. In a managed environment, software installation may also be controlled by organizational policies. Technicians should not simply grant permanent administrator privileges when temporary elevation or an approved deployment process is available. Least privilege should remain the goal while still allowing legitimate software installation.

Question 68

Which Windows command can display information about currently established TCP connections and listening ports?

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

Correct Answer: 1

Explanation

The netstat command provides information about active network connections and listening ports. Depending on the options used, it can display protocol information, local and remote addresses, connection states, and process identifiers. Technicians can use this information when troubleshooting network applications or investigating unexpected listening services. Because the output can contain many entries, appropriate command options should be used to narrow the results. Any suspicious connection should be investigated according to organizational security procedures rather than being automatically assumed to represent malware.

Question 69

A Windows workstation is connected to a network but receives an address beginning with 169.254. What is the most likely issue?

1. DHCP communication failure
2. DNS cache overflow
3. Incorrect monitor driver
4. Printer spooler failure

Correct Answer: 1

Explanation

A 169.254.x.x address is an Automatic Private IP Addressing address that Windows can assign when it cannot obtain an IPv4 address from a DHCP server. The technician should investigate the physical or wireless connection, DHCP availability, VLAN configuration, and network infrastructure. Running ipconfig /renew may help after connectivity is restored. The presence of a 169.254 address does not necessarily mean the network adapter is defective. The technician should determine whether the DHCP request is reaching an available DHCP service.

Question 70

Which Windows command can release the current DHCP-assigned IPv4 address?

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

Correct Answer: 1

Explanation

The ipconfig /release command releases the current DHCP-assigned IPv4 configuration for the selected network adapters. It is commonly followed by ipconfig /renew when troubleshooting DHCP-related connectivity problems. Releasing an address by itself will leave the system without a normal DHCP address until another configuration is obtained. Technicians should use these commands carefully, especially on remote systems, because releasing network configuration can temporarily interrupt connectivity and may prevent remote access until a valid address is obtained again.

Question 71

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

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

Correct Answer: 1

Explanation

The ipconfig /renew command requests a new DHCP configuration from an available DHCP server. It is often used after ipconfig /release when troubleshooting addressing problems. If renewal fails, the technician should investigate physical connectivity, wireless association, DHCP server availability, VLAN configuration, and security controls. A successful renewal does not necessarily prove that all network services are functioning because DNS or routing could still be misconfigured. The command is therefore one step within a broader network troubleshooting process.

Question 72

Which Windows command clears locally cached DNS records?

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

Correct Answer: 1

Explanation

The ipconfig /flushdns command clears the local DNS resolver cache. This can be useful when a computer has cached outdated or incorrect DNS information and continues attempting to connect to an old address. After clearing the cache, Windows can obtain fresh DNS responses when applications request name resolution again. Technicians should understand that flushing the local cache does not correct problems on the DNS server itself. If incorrect records continue to be returned, the DNS infrastructure and authoritative records may need investigation.

Question 73

A user reports that a network application works using an IP address but fails when a hostname is entered. What should be tested first?

1. DNS resolution
2. Display settings
3. CPU temperature
4. Printer drivers

Correct Answer: 1

Explanation

If an application works when connecting directly to an IP address but fails when using a hostname, name resolution is a strong area to investigate. DNS translates hostnames into IP addresses, so the technician should test resolution using tools such as nslookup. The DNS server configuration, DNS records, local cache, and network connectivity to the DNS server should be checked. This symptom helps distinguish a name-resolution problem from a complete network connectivity failure.

Question 74

Which Windows tool can show the hardware resources assigned to installed devices?

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

Correct Answer: 1

Explanation

System Information provides detailed information about hardware resources, system components, and software configuration. Technicians can review areas such as hardware resources, components, and software environment to understand how Windows recognizes the computer. This can help identify configuration conflicts or gather information before troubleshooting. Device Manager is more focused on individual hardware devices and drivers, while System Information provides a broader view of the system’s configuration and assigned resources.

Question 75

A user accidentally deletes an important file and needs to recover an earlier version stored by Windows. Which feature should the technician check?

1. File History
2. Windows Firewall
3. Device Manager
4. Task Scheduler

Correct Answer: 1

Explanation

File History can preserve previous versions of personal files when it has been enabled and configured with a suitable storage destination. A technician can use the available file history to restore an earlier version of a file or recover a deleted file when supported by the configuration. The technician should first confirm that the feature was active before the deletion occurred. If no previous version exists, another approved backup source may be required. Regularly testing backups helps ensure recovery options are actually available.

Question 76

Which Windows feature allows a technician to manage local services and change their startup behavior?

1. Services console
2. Disk Cleanup
3. Paint
4. Calculator

Correct Answer: 1

Explanation

The Services console allows administrators to view Windows services and modify supported service settings. A technician can start, stop, pause, or restart a service and configure its startup type. This is useful when troubleshooting applications or Windows features that depend on background services. Before disabling a service, the technician should determine its purpose and dependencies. Disabling an essential service can cause unexpected operating system or application failures, so service changes should be documented and performed according to organizational procedures.

Question 77

Which Windows feature allows a technician to view and manage hardware devices that have driver problems?

1. Device Manager
2. File History
3. Disk Cleanup
4. Task Scheduler

Correct Answer: 1

Explanation

Device Manager lists installed hardware devices and provides information about their drivers and operational status. Warning icons can indicate problems such as missing, incompatible, disabled, or corrupted drivers. Technicians can use Device Manager to update, roll back, disable, or uninstall drivers when appropriate. Before installing a replacement driver, the technician should verify compatibility with the operating system and hardware. Drivers should preferably be obtained from trusted manufacturer or approved organizational sources.

Question 78

A technician wants to determine which Windows process is listening on a specific TCP port. Which combination can help identify it?

1. netstat and the process information
2. Disk Cleanup and File History
3. Device Manager and Paint
4. System Restore and Calculator

Correct Answer: 1

Explanation

The netstat command can display listening ports and, when used with appropriate options, process identifiers associated with network connections. The technician can correlate the process identifier with Task Manager or another process-management tool to identify the application using the port. This technique is useful when troubleshooting application connectivity or investigating unexpected services. Technicians should verify the legitimacy of the identified process before terminating it because many legitimate Windows and third-party services listen for network connections.

Question 79

A technician is troubleshooting a computer that restarts unexpectedly. Which Windows log can provide useful information about system and application events?

1. Event Viewer
2. Character Map
3. Disk Cleanup
4. Clipboard

Correct Answer: 1

Explanation

Event Viewer provides access to Windows event logs that can contain warnings, errors, and informational messages associated with system and application activity. When a computer restarts unexpectedly, technicians can review relevant events around the time of the incident to identify possible software, driver, service, or system problems. Event logs may not always provide a complete diagnosis, but they can establish a timeline and point toward areas requiring further investigation. The technician should correlate event information with recent changes and observed symptoms.

Question 80

A technician needs to verify that a Windows computer can reach its default gateway. Which command is appropriate?

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

Correct Answer: 1

Explanation

The ping command can test basic IP connectivity between a computer and its default gateway. If the gateway responds, the local system can generally communicate with that network device at the IP layer. If the gateway does not respond, the technician should investigate the network adapter, cable or wireless connection, IP configuration, VLAN, firewall, and gateway availability. A successful gateway ping does not prove that Internet connectivity is working, so additional tests should be performed when troubleshooting access beyond the local network.
