220-1101 Exam Dumps - CompTIA A+ Certification Exam: Core 1

One of the possible causes of random and incorrect characters appearing on print jobs sent to a laser printer is an outdated or corrupted driver. The driver is a software component that communicates between the operating system and the printer, and converts data into a format that the printer can understand. If the driver is outdated or corrupted, it may send incorrect or garbled data to the printer, resulting in poor print quality or errors. The technician should update the driver to the latest version from the manufacturer’s website, or uninstall and reinstall it if necessary.

After resolving an issue, it's crucial for a technician to document the findings, actions taken, and the outcome. This documentation serves several purposes: it provides a record of the problem and the solution for future reference, which can be helpful if the issue recurs or if similar problems arise with other users. It also ensures that any follow-up actions, if necessary, are well-informed by the history of the issue. Documenting the resolution process contributes to knowledge sharing among the support team and can improve the efficiency of future troubleshooting efforts.

After replacing a hot-swappable hard drive in a RAID 5 array, the array must rebuild the data onto the new drive. This process involves reading data from the remaining drives and writing it to the new drive to restore full redundancy. The performance decrease is due to the intensive read and write operations necessary to rebuild the RAID array, which can take several hours depending on the size of the drives and the amount of data.

Removing unnecessary applications frees up storage and processing power, which may allow the device to sync data more effectively. Data caps, Preferred Roaming List settings, and Bluetooth discovery are unrelated to syncing large datasets in cloud storage, as noted in CompTIA A+ Core 1 objectives on mobile device troubleshooting.

The correct answer is B. Replace the bad drive.

A clicking noise coming from a hard drive is a sign of a mechanical failure, which can cause data loss or corruption. Replacing the bad drive as soon as possible is the best way to prevent further damage and restore the RAID array to a healthy state. Reinstalling the drive, resetting the RAID software, or running a chkdek on the drive will not fix the underlying hardware problem and may even worsen the situation. Therefore, option B is the correct answer.

The best option to help the administrator secure the corporate resources is B. Biometric scanner.

A biometric scanner is a device that can authenticate a user’s identity based on their physical or behavioral characteristics, such as fingerprint, iris, face, voice, or signature. A biometric scanner can provide a high level of security and convenience for accessing corporate laptops, as it can prevent unauthorized users from accessing the devices and eliminate the need to remember passwords .

The other options are not the best options for this scenario. A Trusted Platform Module (TPM) is a chip that can store encryption keys and other sensitive data on a laptop. A TPM can enhance the security of data and devices, but it does not limit access to authorized users by itself. A TPM can work with a password or a biometric scanner to provide multifactor authentication . A laptop lock is a device that can physically secure a laptop to a desk or other object using a cable and a lock. A laptop lock can deter theft or tampering, but it does not prevent unauthorized users from accessing the laptop if they have the password or the key. Encryption is a process that can protect data on a laptop by transforming it into an unreadable format using a key. Encryption can prevent unauthorized users from accessing or modifying the data, but it does not prevent them from accessing the laptop itself.

The screen needs to be recalibrated. The cursor drift is a common symptom of a misaligned touch screen, which can be caused by physical shocks, temperature changes, or software updates. The screen can be recalibrated using the tablet’s settings or a utility program. The screen is not physically damaged, as there is no visible crack or break. The screen rotation is not related to the cursor drift, as it only affects the orientation of the display. The touch-pen battery is not relevant, as the cursor drift occurs even without using the pen.

The next troubleshooting step that the technician should attempt is to restart the smartphone. Restarting the smartphone can help resolve many common issues, such as battery drain, network utilization, app crashes, or performance slowdowns. Restarting the smartphone can do the following:

Clear the memory and cache of the smartphone, which can free up space and speed up the device.

Close any background apps or processes that may be consuming battery or network resources, such as syncing, updating, or streaming.

Reset the network settings and connections of the smartphone, which can improve the signal strength and quality.

Refresh the operating system and the user interface of the smartphone, which can fix any glitches or errors.

To restart the smartphone, the user can follow these steps:

Press and hold the power button of the smartphone until a menu appears on the screen.

Tap the option that says Restart, Reboot, or Power off and on.

Wait for the smartphone to turn off and then turn on again.

Enter the PIN, password, or pattern to unlock the smartphone.

Check the battery level and the network utilization of the smartphone.

If restarting the smartphone does not solve the problem, the technician may need to try other troubleshooting steps, such as updating the mobile OS, disabling Bluetooth, or connecting the smartphone to a Wi-Fi network. However, restarting the smartphone is usually the first and simplest step to try.
