A technician wants to install Developer Mode on a Windows laptop but is receiving a "failed to install package" message. Which of the following should the technician do first?
Correct Answer: A
Explanation Developer Mode on Windows 10 is a feature that allows developers to test and debug their applications on their devices, as well as sideload apps and access other developer tools12. To enable Developer Mode, the user needs to go to the Settings app, select Update & Security, choose For Developers, and switch to Developer Mode123. However, enabling Developer Mode requires internet connectivity, as Windows will download and install a package of features, such as Windows Device Portal and SSH services, that are necessary for Developer Mode124. If the user does not have internet connectivity, they will receive a "failed to install package" message when trying to enable Developer Mode4. Therefore, the first thing that the technician should do is to ensure that the laptop has internet access, either through Wi-Fi or Ethernet, and then try to enable Developer Mode again4
Question 272
A user reports seeing random, seemingly non-malicious advertisement notifications in the Windows 10 Action Center. The notifications indicate the advertisements are coming from a web browser. Which of the following is the best solution for a technician to implement?
Correct Answer: D
The best solution for a technician to implement is to disable the browser from sending notifications to the Action Center. This will prevent the random advertisement notifications from appearing in the Windows 10 Action Center, which can be annoying and distracting for the user. The technician can follow these steps to disable the browser notifications1: Open the browser that is sending the notifications, such as Microsoft Edge, Google Chrome, or Mozilla Firefox. Go to the browser settings or options menu, and look for the privacy and security section. Find the option to manage site permissions or notifications, and click on it. You will see a list of sites that are allowed or blocked from sending notifications to the browser and the Action Center. You can either block all sites from sending notifications, or select specific sites that you want to block or allow. Save the changes and close the browser settings. This solution is better than the other options because: Running a full antivirus scan on the computer (B) is not necessary, as the advertisement notifications are not malicious or harmful, and they are not caused by a virus or malware infection. Running a scan will not stop the notifications from appearing, and it will consume system resources and time. Disabling all Action Center notifications is not advisable, as the Action Center is a useful feature that shows notifications and alerts from various apps and system events, such as email, calendar, security, updates, etc. Disabling all notifications will make the user miss important information and reminders, and reduce the functionality of the Action Center. Moving specific site notifications from Allowed to Block (D) is not the best solution, as it will only stop the notifications from some sites, but not from others. The user may still receive advertisement notifications from other sites that are not blocked, or from new sites that are added to the Allowed list. This solution will also require the user to manually manage the list of sites, which can be tedious and time-consuming. Reference: 1: How to Disable Annoying Browser Notifications - PCMag

Question 274
A technician has verified a computer is infected with malware. The technician isolates the system and updates the anti-malware software. Which of the following should the technician do next?
Correct Answer: D
Explanation Malware is malicious software that can cause damage or harm to a computer system or network4. A technician has verified a computer is infected with malware by observing unusual behavior, such as slow performance, pop-ups, or unwanted ads. The technician isolates the system and updates the anti-malware software to prevent further infection or spread of the malware. The next step is to run repeated remediation scans until the malware is removed. A remediation scan is a scan that detects and removes malware from the system. Running one scan may not be enough to remove all traces of malware, as some malware may hide or regenerate itself.
Question 275
A network administrator is setting up the security for a SOHO wireless network. Which of the following options should the administrator enable to secure the network?
Correct Answer: B
To secure a SOHO wireless network, enabling WPA3 is the recommended option. WPA3 (Wi-Fi Protected Access 3) is the latest security certification program developed by the Wi-Fi Alliance to secure wireless computer networks. It provides cutting-edge security protocols and cryptographic methods to enhance and replace its predecessors, WPA2 and WPA, offering improved protection against brute-force attacks and ensuring better privacy on public networks.
