A technician is troubleshooting a Windows system that is having issues with the OS loading at startup.
Which of the following should the technician do to diagnose the issue?
- A . Enable boot logging on the system.
- B . Launch the last known-good configuration.
- C . Check the system resource usage in Task Manager.
- D . Run the sfc /scannow command.
- E . Use the Event Viewer to open the application log
Correct Answer: A
A
Explanation:
When troubleshooting a Windows system that is experiencing issues during the OS loading phase at startup, enabling boot logging is a practical step. Boot logging creates a record of all drivers and services that are loaded (or attempted to be loaded) during the startup process. This record, typically named ntbtlog.txt, can be reviewed to identify any drivers or services that failed to load, which could be contributing to the startup issues. This diagnostic step helps pinpoint the problematic component(s) and facilitates targeted troubleshooting to resolve the OS loading issues.

Therefore, if NFC is disabled on the phone, the payment will not work.
To enable NFC on an Android phone, you need to follow these steps3:
✑ On your Android device, open the Settings app.
✑ Select Connected devices.
✑ Tap on Connection preferences.
✑ You should see the NFC option. Toggle it on.
The other options are not directly related to using a payment application with a mobile device. Airplane mode is a setting that disables all wireless communication on the phone, including NFC4, but it also affects calls, texts, and internet access. Bluetooth is a wireless technology that allows you to connect your phone with other devices such as headphones or speakers, but it is not used for contactless payments. Wi-Fi is a wireless technology that allows you to access the internet or a local network, but it is also not used for contactless payments. Location services are a feature that allows your phone to determine your geographic location using GPS or other methods, but they are not required for contactless payments.

Question #237
Which of the following provide the BEST way to secure physical access to a data cento server room? (Select TWO).
- A . Biometric lock
- B . Badge reader
- C . USB token
- D . Video surveillance
- E . Locking rack
- F . Access control vestibule
Correct Answer: A,D
A,D
Explanation:
Biometric locks provide a high level of security because they require unique physical characteristics such as fingerprints or retinal scans to grant access. This makes them difficult to bypass because these characteristics are unique to each individual.
Video surveillance is another important layer of physical security that can deter unauthorized access and provide a record of who enters and exits the server room. This can be useful for investigative purposes if any problems occur.
Although badge readers (B), USB tokens (C), and access control vestibules (F) can be used as part of a comprehensive security strategy, they can potentially be bypassed or stolen, making them less secure than biometric locks. Locking racks (E) protect the hardware within the data center but do not limit access to the room itself.

Question #240
A user’s Windows 10 workstation with an HDD is running really slowly. The user has opened, closed, and saved many large files over the past week.
Which of the following tools should a technician use to remediate the issue?
- A . Disk Defragment
- B . Registry Editor
- C . System Information
- D . Disk Cleanup
Correct Answer: A
A
Explanation:
Over time, especially with frequent opening, modification, and saving of large files, a hard disk drive (HDD) can become fragmented. Fragmentation occurs when pieces of individual files are scattered across the disk, leading to longer read and write times, which can significantly slow down the computer. Disk defragmentation reorganizes these fragmented files, placing the pieces closer together on the drive, which improves access time and overall system performance.
Disk Defragment: Using the Disk Defragment tool on a Windows 10 system with an HDD will help in reorganizing the data more efficiently, thus potentially remedying the slow performance issue.
The Registry Editor (B) is a tool that allows for the viewing and editing of the Windows registry and is generally not used for performance improvement but rather for system settings and configuration adjustments. System Information (C) provides a detailed look at the computer’s hardware and system details but does not offer tools for performance improvement. Disk Cleanup (D) can help free up space on the hard drive by removing temporary files and system files that are no longer needed, which can indirectly improve performance but is not the primary tool for addressing fragmentation.
