• Question 521:

  Which of the following languages is used for scripting the creation of Active Directory accounts?

  A. Bash

  B. SQL

  C. PHP

  D. PowerShell

  Correct Answer: D

  PowerShell is a scripting language that can interact with Active Directory and other Windows components. It has a built-in cmdlet called New-ADUser that can create user accounts in Active Directory. PowerShell can also use the Active Directory module to access other AD-related functions and attributes. Other languages, such as Bash, SQL, and PHP, are not designed for creating Active Directory accounts and would require additional tools or libraries to do so

• Question 522:

  A user receives a call from someone claiming to be a technical support agent. The caller asks the user to log in to the computer.

  Which of the following security measures should the user take to ensure security and privacy?

  A. Only accept calls from known people.

  B. Disregard any suspicious emails.

  C. Update the antivirus software.

  D. Enable two-factor authentication.

  E. Install a malware scanner.

  Correct Answer: A

  This is a scenario of a potential tech support scam, where a fraudster pretends to be a technical support agent and tries to trick the user into giving them access to the computer, personal information, or money. The user should not trust any unsolicited calls from unknown people claiming to be from tech support, as they might be trying to install malware, steal data, or charge for fake services. The user should only accept calls from known people, such as their IT department, their service provider, or their software vendor, and verify their identity before logging in to the computer. The user should also report any suspicious calls to the appropriate authorities or organizations.

• Question 523:

  The calendar application on an employee's smartphone is experiencing frequent crashes, and the smartphone has become unresponsive. Which of the following should a technician do first to resolve the issue?

  A. Reinstall the application on the smartphone.

  B. Update the smartphone's OS.

  C. Reset the smartphone to factory settings.

  D. Reboot the smartphone.

  Correct Answer: D

  Rebooting the smartphone is the first and simplest step to resolve the issue of frequent crashes and unresponsiveness. Rebooting clears the memory, closes the background apps, and refreshes the system. It can also fix minor glitches and bugs that may cause the calendar app or the smartphone to malfunction12. The other options are either too drastic or unnecessary. Reinstalling the application may not solve the problem if the issue is with the smartphone itself. Updating the smartphone's OS may not be possible or helpful if the device is unresponsive or incompatible. Resetting the smartphone to factory settings will erase all the data and settings on the device, which should be the last resort.

• Question 524:

  A technician is troubleshooting a PC because the user has reported strange pop-up windows and computer performance issues. Which of the following actions should the technician take next?

  A. Isolate the machine from the network.

  B. Scan the system for hidden files.

  C. Disable unused ports.

  D. Install antivirus software.

  E. Reconfigure the firewall.

  Correct Answer: A

  Isolating the machine from the network is a good practice when troubleshooting a PC that is suspected of being infected with malware. This can prevent the malware from spreading to other devices on the network or communicating with external servers that may control or exploit the malware. Isolating the machine can be done by disconnecting the network cable, disabling the wireless adapter, or blocking the network traffic with a firewall.

• Question 525:

  A technician downloaded a software program to a network share. When the technician attempts to copy the program to the Windows tablet for installation, the technician receives an error. Which of the following is the best procedure for the technician to use to complete the assignment?

  A. Copy the program file to a USB drive and install.

  B. Burn the program file to a CD and install.

  C. Format the HDD and then do the installation.

  D. Replace the HDD and then do the installation.

  Correct Answer: A

  Copying the program file to a USB drive and installing it from there is the simplest and most reliable way to transfer the software from the network share to the Windows tablet. The other options are either unnecessary, risky, or impractical. Burning the program file to a CD requires a CD burner and a CD reader, which may not be available on the tablet. Formatting or replacing the HDD will erase all the data and settings on the tablet, which is not advisable unless there is a backup or a serious problem. Moreover, formatting or replacing the HDD will not solve the issue of copying the program file from the network share.

• Question 526:

  A user's Windows computer seems to work well at the beginning of the day. However, its performance degrades throughout the day, and the system freezes when several applications are open. Which of the following should a technician do to resolve the issue? (Select two).

  A. Install the latest GPU drivers.

  B. Reinstall the OS.

  C. Increase the RAM.

  D. Increase the hard drive space.

  E. Uninstall unnecessary software.

  F. Disable scheduled tasks.

  Correct Answer: CE

  The most likely causes of the user's Windows computer performance degradation and freezing are insufficient RAM and excessive software running in the background. Therefore, the technician should do the following to resolve the issue: Increase the RAM. RAM is the memory that the computer uses to store and run applications and processes. If the RAM is not enough to handle the workload, the computer will use the hard drive as a virtual memory, which is much slower and can cause performance issues. Increasing the RAM will allow the computer to run more applications and processes smoothly and avoid freezing. The technician should check the system requirements of the applications that the user needs to run, and install additional RAM modules that are compatible with the motherboard and the existing RAM. The technician should also make sure that the system is managing the page file size automatically, or adjust it manually to optimize the virtual memory usage12. Uninstall unnecessary software. Software that the user does not need or use can take up valuable disk space and system resources, and can interfere with the performance of other applications. Some software may also run in the background or start automatically when the computer boots up, which can slow down the system and cause freezing. The technician should help the user to identify and uninstall unnecessary software from the control panel or the settings app, and disable unnecessary startup programs from the task manager or the system configuration tool. The technician should also check for and remove viruses and malware that may affect the system performance134. References:

• Question 528:

  A developer reports that a workstation's database file extensions have been changed from .db to .enc. The developer is also unable to open the database files manually. Which of the following is the best option for recovering the data?

  A. Accessing a restore point

  B. Rebooting into safe mode

  C. Utilizing the backups

  D. Using an AV to scan the affected files

  Correct Answer: C

  The scenario described in the question suggests that the workstation has been infected by a ransomware, which is a type of malware that encrypts the files on the target system and demands a ransom for the decryption key12. The file extension .enc is commonly used by some ransomware variants to mark the encrypted files34. The developer is unable to open the database files manually because they are encrypted and require the decryption key, which is usually held by the attacker. The best option for recovering the data is to utilize the backups, assuming that the backups are recent, valid, and not affected by the ransomware. Backups are copies of the data that are stored in a separate location or device, and can be used to restore the data in case of a disaster, such as a ransomware attack . By restoring the data from the backups, the developer can avoid paying the ransom and losing the data permanently. Accessing a restore point is not a good option, because restore points are snapshots of the system settings and configuration, not the data files. Restore points can help to undo some system changes, such as installing a faulty driver or software, but they cannot recover the encrypted data files . Rebooting into safe mode is also not a good option, because safe mode is a diagnostic mode that allows the system to run with minimal drivers and services, but it does not affect the data files. Safe mode can help to troubleshoot some system issues, such as malware infections, but it cannot decrypt the data files . Using an AV to scan the affected files is also not a good option, because an AV is a software that can detect and remove some malware, but it cannot decrypt the data files. An AV can help to prevent or remove some ransomware infections, but it cannot recover the encrypted data files .

• Question 529:

  A technician is hardening a company file server and needs to prevent unauthorized LAN devices from accessing stored files. Which of the following should the technician use?

  A. Software firewall

  B. Password complexity

  C. Antivirus application

  D. Anti-malware scans

  Correct Answer: A

  A software firewall is a program that monitors and controls the incoming and outgoing network traffic on a computer or a server. A software firewall can help prevent unauthorized LAN devices from accessing stored files on a company file

  server by applying rules and policies that filter the network packets based on their source, destination, protocol, port, or content. A software firewall can also block or allow specific applications or services from communicating with the network,

  and alert the administrator of any suspicious or malicious activity12.

  A software firewall is a better option than the other choices because:

  Password complexity (B) is a good practice to protect the file server from unauthorized access, but it is not sufficient by itself. Password complexity refers to the use of strong passwords that are hard to guess or crack by attackers, and that

  are changed frequently and securely. Password complexity can prevent brute force attacks or credential theft, but it cannot stop network attacks that exploit vulnerabilities in the file server software or hardware, or that bypass the

  authentication process34. Antivirus application ?and anti-malware scans (D) are important tools to protect the file server from viruses and malware that can infect, damage, or encrypt the stored files. However, they are not effective in

  preventing unauthorized LAN devices from accessing the files in the first place. Antivirus and anti-malware tools can only detect and remove known threats, and they may not be able to stop zero- day attacks or advanced persistent threats

  that can evade or disable them. Moreover, antivirus and anti-malware tools cannot control the network traffic or the file server permissions, and they may not be compatible with all file server platforms or configurations56.
