The sfc command is a tool for scanning and repairing system files that are corrupted or missing on Windows operating systems12. System files are essential files that are required for the proper functioning of the operating system, such as the GUI, drivers, services, and applications. If system files are damaged or deleted, the operating system may fail to start or run properly, causing errors, crashes, or blue screens.

The sfc command can be used to fix the issue of the PC that is unable to start the GUI, assuming that the problem is caused by corrupted or missing system files. The sfc command can be run from the command prompt, which can be accessed by booting the PC from the installation media, choosing the repair option, and selecting the command prompt option3. The sfc command can be used with different switches, such as /scannow, /verifyonly, /scanfile, or /offbootdir, depending on the situation and the desired action4. The most common switch is /scannow, which scans all the system files and repairs any problems that are found5. The syntax of the sfc command with the /scannow switch is:

sfc /scannow

The sfc command will then scan and repair the system files, and display the results on the screen. If the sfc command is able to fix the system files, the PC should be able to start the GUI normally after rebooting. If the sfc command is unable to fix the system files, the PC may need further troubleshooting or a clean installation of Windows.

To change the wallpaper on a Windows 10 laptop, the "Personalization" settings should be used. These settings allow users to customize themes, which include various aspects of the desktop environment such as the desktop wallpaper, screen saver, color scheme, and more. This makes "Personalization" the correct option for customizing the wallpaper.References: Official CompTIA A+ Core 1 and Core 2 Student Guide​​.

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.

The protocol that most likely allowed the data theft to occur is SMB over TCP port 445. SMB is a network file sharing protocol that enables access to files, printers, and other resources on a network. Port 445 is used by SMB to communicate directly over TCP without the need for NetBIOS, which is an older and less secure protocol. The security log shows that the source IP address 192.168.1.1 sent a file named secrets.zip using SMB protocol to the destination IP address 192.168.1.50, which captured the file. The Windows firewall information shows that port 445 is enabled for inbound and outbound traffic, which means that it is not blocked by the firewall. Therefore, port 445 is the most likely port that was exploited by the attacker to steal the data from the corporate laptop.

An acceptable use policy (AUP) is a document that defines the rules and expectations for the users of a system, network, or service. It typically covers topics such as the purpose, scope, responsibilities, and restrictions of using the system, network, or service1. An AUP is a suitable place to publish the guidelines for the incorporation of generative AI solutions, as it can inform the users of the benefits, risks, and ethical implications of using such tools. It can also specify the conditions and limitations for using generative AI solutions, such as the types of data, content, and applications that are allowed or prohibited, the security and privacy requirements, the legal and regulatory compliance, and the accountability and reporting mechanisms23.
