exFAT is a file system that is supported by both Linux and Windows and can handle large files1.

Since the systems administrator has validated that the workstation functions normally and other users operate on the same workstation without any issues, the next step should be to rebuild the user's profile. This will ensure that any corrupted files or settings are removed and the user's profile is restored to its default state.

The nslookup command is a network administration tool used for querying the Domain Name System (DNS) to obtain domain name or IP address mapping or for any other specific DNS record. It's the most direct way to verify if a PC can resolve a website's domain name to its IP address.
Here's why the other options are not the primary tools for this task:
* B. hostname: This command displays the hostname of the computer.
* C. tracert: This command traces the route packets take to reach a specific destination. It can help identify network connectivity issues but doesn't directly test DNS resolution.
* D. netstat: This command displays active network connections and listening ports. It's not used for DNS troubleshooting.
How to use nslookup:
* Open a command prompt.
* Type nslookup <website address> (e.g., nslookup google.com) and press Enter.
* The output will show the DNS server used and the IP address(es) associated with the website.
* If the command returns an error or doesn't show an IP address, it indicates a problem with DNS resolution.

According to CompTIA A+ Core 2 objectives, a full backup stored off-site provides the greatest protection against data loss in the event of a ransomware attack or other data disaster. By storing the backup in a separate physical location, it is less likely to be affected by the same event that could cause data loss on the original system. Cold storage is a term used for data archiving, which typically refers to a long-term storage solution that is used for retaining data that is infrequently accessed, but still needs to be kept for regulatory or compliance reasons.
