A macOS user reports seeing a spinning round cursor on a program that appears to be frozen. Which of the following methods does the technician use to force the program to close in macOS?
The technician opens the Apple icon menu, selects Force Quit, selects the frozen application in the list, and clicks Force Quit. This is the most common method of force quitting a program in macOS. This can be done by clicking on the Apple icon in the top left of the screen, selecting Force Quit, selecting the frozen application in the list, and then clicking Force Quit. This will force the application to quit and the spinning round cursor will disappear.
After a security event, a technician removes malware from an affected laptop and disconnects the laptop from the network. Which of the following should the technician do to prevent the operating system from automatically returning to an infected state?
System Restore is a feature that allows the user to revert the system to a previous state. However, this can also restore the malware that was removed by the technician. Disabling System Restore can prevent the operating system from automatically returning to an infected state. Enabling antivirus, educating the user, and enabling System Restore are good preventive measures, but they do not address the question. Disabling antivirus can make the system more vulnerable to malware attacks
A help desk technician is troubleshooting a workstation in a SOHO environment that is running above normal system baselines. The technician discovers an unknown executable with a random string name running on the system. The technician terminates the process, and the system returns to normal operation. The technician thinks the issue was an infected file, but the antivirus is not detecting a threat. The technician is concerned other machines may be infected with this unknown virus. Which of the following is the MOST effective way to check other machines on the network for this unknown threat?
The most effective way to check other machines on the network for this unknown threat is to manually check each machine. This can help to identify any other machines that may be infected with the unknown virus and allow them to be cleaned.
A network technician is deploying a new machine in a small branch office that does not have a DHCP server. The new machine automatically receives the IP address of 169.254.0.2 and is unable to communicate with the rest of the network. Which of the following would restore communication?
Static entry
A static entry is the best option to restore communication for the new machine in a small branch office that does not have a DHCP server. A static entry means manually configuring the IP address, subnet mask, default gateway, and DNS server for the network adapter of the machine. A static entry ensures that the machine has a valid and unique IP address that matches the network configuration and can communicate with the rest of the network.
The new machine automatically receives the IP address of 169.254.0.2 because it uses APIPA (Automatic Private IP Addressing), which is a feature that enables computers to self-assign an IP address when a DHCP server is not available. However, APIPA only works for local communication within the same subnet, and does not provide a default gateway or a DNS server. Therefore, the new machine is unable to communicate with the rest of the network, which may be on a different subnet or require a gateway or a DNS server to access.
The other options are not related to restoring communication for the new machine. ARP table is a cache that stores the mapping between IP addresses and MAC addresses for the devices on the network. NTP specification is a protocol that synchronizes the clocks of the devices on the network.

A technician needs to configure security settings on a Windows 10 workstation. Which of the following should the technician configure to limit password attempts?
Configuring the Account Lockout Policy in Windows 10 is the appropriate action to limit password attempts. This security setting determines the number of failed login attempts that will trigger a lockout, preventing unauthorized access due to repeated password guessing. It is an effective measure to enhance security by deterring brute-force attacks.
