A technician is troubleshooting boot times for a user. The technician attempts to use MSConfig to see which programs are starting with the OS but receives a message that it can no longer be used to view startup items. Which of the following programs can the technician use to view startup items?
- A. msinfo32
- B. perfmon
- C. regedit
- D. taskmgr
Answer: D
Explanation:
When troubleshooting boot times for a user, a technician may want to check which programs are starting with the operating system to identify any that may be slowing down the boot process. MSConfig is a tool that can be used to view startup items on a Windows system, but it may not always be available or functional.
In this scenario, the technician receives a message that MSConfig cannot be used to view startup items. As an alternative, the technician can use Task Manager (taskmgr), which can
also display the programs that run at startup. To access the list of startup items in Task Manager, the technician can follow these steps:

NEW QUESTION 4
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?
- A. Disable the browser from sending notifications to the Action Center.
- B. Run a full antivirus scan on the computer.
- C. Disable all Action Center notifications.
- D. Move specific site notifications from Allowed to Block.
Answer: A
Explanation:
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.

NEW QUESTION 11
A technician receives an invalid certificate error when visiting a website. Other workstations on the same local network are unable to replicate this issue. Which of the following is mostlikely causing the issue?
- A. Date and time
- B. User access control
- C. UEFI boot mode
- D. Log-on times
Answer: A
Explanation:
Date and time is the most likely cause of the issue. The date and time settings on a workstation affect the validity of the certificates used by websites to establish secure connections. If the date and time are incorrect, the workstation may not recognize the certificate as valid and display an invalid certificate error. Other workstations on the same local network may not have this issue if their date and time are correct. User access control, UEFI boot mode, and log-on times are not likely causes of the issue. User access control is a feature that prevents unauthorized changes to the system by prompting for confirmation or credentials. UEFI boot mode is a firmware interface that controls the boot process of the workstation. Log-on times are settings that restrict when a user can log in to the workstation. None of these factors affect the validity of the certificates used by websites. References:
