A technician is trying to encrypt a single folder on a PC. Which of the following should the technician use to accomplish this task?
Answer: D
EFS is a built-in Windows feature that allows you to encrypt individual files and folders. When you enable EFS on a folder, the files within that folder are encrypted using a unique key tied to the user's account. This means that only the user who encrypted the files (or users with appropriate permissions) can access them. EFS is a good choice if you want to protect specific files or folders on a Windows system without encrypting the entire drive. BitLocker, on the other hand, is primarily used for full-disk encryption. When enabled, it encrypts the entire drive, including all files and folders on it. While BitLocker can encrypt individual folders as well, it is more commonly used to encrypt the entire system drive or additional data drives. BitLocker is useful when you want to protect all the data on a drive and ensure that it remains encrypted even if it is removed from the computer.

A company is looking for a solution that provides a backup for all data on the system while providing the lowest impact to the network. Which of the following backup types will the company MOST likely select?
Answer: B
C. Full Backup: This type of backup copies all the data, regardless of whether it has changed since the last backup. While it provides complete data protection, it can consume more network bandwidth and storage space, potentially impacting the network. D. Differential Backup: A differential backup captures only the changes made since the last full backup. While it requires less storage space compared to a full backup, it still captures a significant amount of data, which could impact the network. Given that the company is looking for a solution with the lowest impact on the network while providing backup for all data, the best choice is: B. Synthetic Backup: A synthetic backup combines incremental changes with a full backup to create a "synthetic full" backup. It reduces the need to transfer large amounts of data over the network while providing comprehensive data protection. chatGPT
