220-1102 Practice Test

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.

Explanation:
the user should change the default passwords first when configuring a new SOHO Wi-Fi router.

Explanation: Configuring remote wipe allows the device owner or administrator to erase all the data on the device remotely, in case it is lost or stolen. This prevents unauthorized access to confidential data and reduces the risk of data breaches. Installing a VPN, implementing location tracking, and enabling backups are useful features, but they do not directly limit the loss of data if the device is compromised.

Explanation:
This is the most effective way to selectively prevent programs from loading on a Windows 10 machine. The Startup tab can be accessed by opening Task Manager and then selecting the Startup tab. From there, the technician can methodically disable items that are currently listed as enabled, reboot the machine, and check for issue resolution at each startup. If the issue persists, the technician can then move on to disabling the next item on the list.

Explanation: 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.
