When a user needs to install optional features for a program that is already installed, the technician should:

Go to Programs and Features: Access this via the Control Panel.

Select the program: Find the installed program in the list.

Click on Change: The "Change" option allows modifications to the installed program, such as adding or removing features, without completely uninstalling and reinstalling the program.

This method is the most efficient and avoids unnecessary reinstallation of the software, which could lead to data loss or require reconfiguration.

The technician should configure the network as private to allow the user to access files on a drive shared from another desktop on the network1

A biometric lock requires an authorized user to provide a unique biometric identifier, such as a fingerprint, in order to gain access to the server room. A badge reader requires an authorized user to swipe an access card in order to gain access. Both of these methods ensure that only authorized personnel are able to access the server room. Additionally, video surveillance and access control vestibules can be used to further secure the server room. Finally, a locking rack can be used to physically secure the servers, so that they cannot be accessed without the appropriate key.

To help secure the device against this threat in the future, the administrator should require a PIN on the unlock screen and block a third-party application installation. Requiring a PIN on the unlock screen can help to prevent unauthorized access to the device, while blocking third-party application installation can help to prevent malicious applications from being installed on the device.

The user can enable speech recognition on a PC in the Ease of Access settings tool. To set up Speech Recognition on a Windows PC, the user should open Control Panel, click on Ease of Access, click on Speech Recognition, and click the Start Speech Recognition link.

System settings can be used to configure the hardware and software of the PC, but they will not enable the speech recognition feature. Personalization settings can be used to customize the appearance and behavior of the PC, but they will not enable the speech recognition feature1

Open up ease of access, click on speech, then there is an on and off button for speech recognition.

Group Policy is a feature of Windows that allows administrators to centrally manage and apply policies and settings to computers and users on a domain3. Group Policy can be used to configure network drives, printers, security settings, desktop preferences, and other configurations for all users’ workstations3. Network and Sharing Center, net use, User Accounts, and regedit are not tools that can accomplish this task.

A checksum is a cryptographic hash function (like MD5 or SHA-256) used to verify the integrity of files. When downloading files from the internet, websites often provide the checksum value of the file so that users can ensure the file was not altered during download or corrupted. The user can generate the checksum on their local system and compare it to the one provided by the site. If they match, the file is intact and safe to use. Other options like BitLocker or FileVault are encryption tools, and a password manager is irrelevant to file verification.
