While browsing the internet, a customer sees a window stating antivirus protection is no longer functioning Which of the following steps should a technician take next? (Select two).
A. Isolate the computer from the network
B. Enable the firewall service.
C. Update the endpoint protection software
D. Use System Restore to undo changes.
E. Delete the browser cookies
F. Run sfc /scannow.
Correct Answer: A
When encountering a warning about antivirus protection malfunctioning, the first step should be to isolate the computer from the network to prevent potential spread of malware. Updating the endpoint protection software is also crucial to ensure the latest virus definitions and security features are in place to effectively identify and remove the threat.
Question 622:
A company wants to take advantage of modern technology and transition away from face- to-face meetings. Which of the following types of software would benefit the company the most? (Select two).
A. Videoconferencing
B. File transfer
C. Screen-sharing
D. Financial
E. Remote access
F. Record-keeping
Correct Answer: AC
For a company looking to transition away from face-to-face meetings, videoconferencing and screen-sharing software would be most beneficial. Videoconferencing software allows participants to conduct virtual meetings with audio and video capabilities, effectively simulating a face-to-face interaction without the need for physical presence. This can greatly reduce travel costs and time while maintaining the personal touch of meetings. Screen-sharing enables participants in a virtual meeting to view one another's computer screens in real time. This is particularly useful for presentations, collaborative work, and troubleshooting, as it allows for a more interactive and engaging meeting experience. Both technologies support the company's goal of leveraging modern technology to enhance communication and collaboration while reducing reliance on physical meetings.
Question 623:
A technician downloaded an OS installation file but is unable to run it. When the technician tries to open the file, a message indicates no software is installed to run this file. Which of the following should the technician do next to attempt to access the OS file?
A. Request physical media
B. Mount the ISO file.
C. Install a third-party software.
D. Download an appropriate 32-bit/64-bit OS file.
Correct Answer: B
If a technician is unable to run an OS installation file and receives a message indicating no software is installed to handle the file, the next step is to mount the ISO file. Mounting the ISO will create a virtual drive from which the installation can be run, mimicking the behavior of a physical installation media.
Question 624:
A user's workstation was infected with a newly discovered virus that the AV system detected. After a full virus scan and a workstation reboot, the virus is still present in the OS. Which of the following actions should the user take to remove the virus?
A. Enable the system firewall.
B. Use bootable antivirus media to scan the system.
C. Download software designed to specifically target the virus.
D. Run the operating system update process.
Correct Answer: B
Using bootable antivirus media to scan the system is an effective method for removing a persistent virus. Booting from external antivirus media allows the system to scan for and remove malware without the infected operating system running, which can prevent the virus from hiding or resisting removal efforts that might occur within the active OS environment.
Question 625:
A user reports receiving constant, unwanted pop-ups and being unable to close the browser window. These issues have impacted the user's productivity and may have caused the user's files to be altered. Which of the following should a technician do to address these issues with minimal impact to the user?
A. Use System Restore to recover the OS files.
B. Wipe the computer and install a new copy of the OS.
C. Identify whether the disk partition table has been reduced in size.
D. Perform a full-system, antivirus scan and check browser notifications.
Correct Answer: D
For issues related to constant, unwanted pop-ups and browser window problems, a careful approach that minimizes impact to the user's data and productivity is advisable:
Perform a full-system, antivirus scan: This step involves using antivirus software to scan the entire system for malware or adware that might be causing the pop-ups and browser issues. Check browser notifications: Some unwanted pop-ups
may result from browser notification permissions inadvertently granted to malicious or spammy websites. Reviewing and adjusting these settings can help stop the pop-ups.
Question 626:
A technician needs to strengthen security controls against brute-force attacks. Which of the following options best meets this requirement?
A. Multifactor authentication
B. Encryption
C. Increased password complexity
D. Secure password vault
Correct Answer: A
Multifactor authentication (MFA) significantly enhances security by requiring two or more forms of verification before granting access to an account or system. This method is highly effective against brute-force attacks, where attackers attempt to guess a user's password through repeated trials. By implementing MFA, even if a password is compromised, unauthorized access is still prevented without the additional authentication factor(s), such as a code from a smartphone app, a fingerprint, or a physical security token. Multifactor authentication: Provides an additional layer of security beyond just the password, making it much harder for attackers to gain unauthorized access through brute-force methods, as they would need to compromise more than one authentication factor. Encryption (B) is crucial for protecting data at rest and in transit, but it does not directly prevent brute-force login attempts. Increased password complexity (C) can deter brute- force attacks by making passwords harder to guess, but it is not as effective as MFA in preventing access when passwords are compromised. A secure password vault (D) helps users manage and store their passwords securely, which can indirectly contribute to security by allowing users to keep more complex passwords, but it does not directly prevent brute-force attacks on accounts.
Question 627:
A user submits a request to have a graphics application installed on a desktop When the technician attempts to install the application, the installation fails and the error message "Not compatible with OS' is displayed. Which of the following is the most likely reason for this error message?
A. Thegraphics card driver needs to beupdated
B. Theapplication installer is 64-bit.
C. Theinstallation requires administrative rights.
D. Thedisk space is inadequate.
Correct Answer: C
The most likely reason for an error message stating "Not compatible with OS" during a software installation is that the installation requires administrative rights. Many software installations, especially those that affect system files or install drivers, require administrative privileges to execute correctly. Without these rights, the installer cannot make the necessary changes to the system, leading to such error messages.
Question 628:
A home office user wants to ensure a PC is backed up and protected against local natural disasters and hardware failures. Which of the following would meet the user's requirements?
A. Using an agent-based cloud backup solution
B. Implementing a grandfather-father-son backup rotation
C. Automating backups to a local network share
D. Saving files manually to an external drive
Correct Answer: A
Question 629:
A user wants to back up a device's OS and data. Which of the following is the best way to accomplish this task?
A. Incremental backup
B. System image
C. System restore point
D. Differential backup
Correct Answer: B
A system image is a complete snapshot of everything on a device's storage at a given point in time, including the operating system, installed programs, system settings, and all user files. This method is the best way to back up the OS and data comprehensively because it allows for the restoration of a system to its exact state at the time the image was taken. This is particularly useful in disaster recovery scenarios where it's crucial to restore a system quickly and efficiently to minimize downtime.
Question 630:
A user's work PC has been the target of multiple phishing attacks. Which of the following is a way for the user to prevent further attacks?
