SFC can be used to detect and fix any modified or corrupted system files on a computer, and thus should be checked first when a user reports that their computer has been runningslowly since the installation of security applications [1][2]. By checking SFC, any modified or corrupted system files can be identified and fixed, potentially improving the overall performance of the computer.

Which of the following would most likely be used in a small office environment?

• A. Print server
• B. Virtualization
• C. Domain access
• D. Workgroup

Answer: D

Explanation:
A workgroup is a network configuration that allows computers to communicate and share resources with each other without requiring a centralized server or domain controller. A workgroup is suitable for small office environments where there are only a few computers and users who need simple file and printer sharing. A workgroup does not have centralized management or security policies, which may be desirable for larger or more complex networks. Print server, virtualization, and domain access are not network configurations that are most likely used in a small office environment.

NEW QUESTION 7
A company recently experienced a security incident in which a USB drive containing malicious software was able to covertly install malware on a workstation_ Which of thefollowing actions should be taken to prevent this Incident from happening again? (Select two).

• A. Install a host-based IDS
• B. Restrict log-in times.
• C. Enable a BIOS password
• D. Update the password complexity
• E. Disable AutoRun.
• F. Update the antivirus definitions.
• G. Restrict user permissions.

Answer: EF

Explanation:
The correct answers are E and F. Disabling AutoRun and updating the antivirus definitions are two actions that should be taken to prevent the incident from happening again.
AutoRun is a feature of Windows that automatically executes a predetermined action when a removable media such as a USB drive is inserted in a computer. For example, AutoRun can launch or install a new program on the media, or open the file in File Explorer. However, this feature can also be exploited by malicious software that can run without the user’s consent or knowledge. Therefore, disabling AutoRun can help prevent accidental installation of viruses and other malware from USB drives123.
Updating the antivirus definitions is another important action that can help prevent malware infections from USB drives. Antivirus definitions are files that contain information about the latest known threats and how to detect and remove them. By updating the antivirus definitions regularly, you can ensure that your antivirus software can recognize and block any malicious software that may be on the USB drive before it can harm your computer45. A host-based IDS is a system that monitors and analyzes the activity on a single computer or device for any signs of intrusion or malicious behavior. A host-based IDS can help detect and prevent malware infections from USB drives, but it is not a sufficient action by itself. A host-based IDS needs to be complemented by other security measures, such as disabling AutoRun and updating the antivirus definitions6.
Restricting login times, enabling a BIOS password, and updating the password complexity are all actions that can help improve the security of a computer or device, but they are not directly related to preventing malware infections from USB drives. These actions can help prevent unauthorized access to the computer or device, but they do not affect how the computer or device interacts with the USB drive or its contents.
Restricting user permissions is an action that can help limit the damage that malware can cause on a computer or device, but it does not prevent the malware from being installed in the first place. Restricting user permissions means limiting what actions a user can performon the computer or device, such as installing or deleting programs, modifying system settings, or accessing certain files or folders. By restricting user permissions, you can reduce the impact of malware infections by preventing them from affecting other users or system components7.

NEW QUESTION 8
A user connected an external hard drive but is unable to see it as a destination to save files. Which of the following tools will allow the drive to be formatted?

• A. Disk Management
• B. Device Manager
• C. Disk Cleanup
• D. Disk Defragmenter

Answer: A

Explanation:
Disk Management is a tool that allows users to create, format, delete, shrink, extend, and manage partitions on hard drives. If the external hard drive is not formatted or has an incompatible filesystem type, Disk Management can be used to format it with a supported filesystem type such as NTFS, FAT32, or exFAT. Device Manager, Disk Cleanup, and Disk Defragmenter are not tools that can format a hard drive.

NEW QUESTION 9
Which of the following is used as a password manager in the macOS?

• A. Terminal

You can use the Keychain Access app on your Mac to view and manage your keychains and the items stored in them1. Keychain can also sync your passwords and other secure informationacross your devices using iCloud Keychain1. Keychain can be used as a password manager in macOS to help you keep track of and protect your passwords.

Which of the following does MFA provide?
✑ Security enhancement
✑ Encryption
✑ Digital signature

• A. Public key infrastructure

Answer: A

Explanation:
MFA stands for multi-factor authentication, which is an electronic authentication method that requires the user to provide two or more verification factors to gain access to a resource such as an application, online account, or a VPN1. MFA provides security enhancement by making it harder for attackers to compromise the user’s identity or credentials, as they would need to obtain more than just the username and password. MFA can also prevent unauthorized access to sensitive data or resources, as well as reduce the risk of identity theft or fraud2.
