The ___ ___ is a local plain text file that maps servers or hostnames to IP addresses
Host file - It was the original method to resolve hostnames to a specific IP address. The hosts file is usually the first process in the domain name resolution procedure. When a user requests a webpage, the hosts.ini file is first checked for the IP address. If the IP address isn't found in the hosts.ini file, then the workstation requests the IP address from the DNS server. Attackers often modify host.ini files to redirect users to a malicious webpage instead of one they would commonly use like Google, Facebook, and others.
Upon booting up a Windows 10 machine, you see an error message stating, "One or more services failed to start." Which of the following actions should you take?
If you see a message such as "One or more services failed to start" during the Windows load sequence, check Event Viewer and/or the Services snap-in to identify which service has failed. Troubleshooting services can be complex. Of the options presented in this question, only the one for verifying that disabling one service has not affected others would help correct a service that fails to start. This is because some services depend on other services to run, so if something or someone has disabled one service, it could have inadvertently affected others.
when installing a video editing application, the installation process fails due to lack of available drive space. Which of the following would be the BEST way to complete the installation process?

Wired equivalent privacy (WEP) is an older mechanism for encrypting data sent over a wireless connection. WEP is considered vulnerable to attacks that can break its encryption. WEP relies on the use of a 24-bit initialization vector to secure its preshared key.
What type of wireless security measure can easily be defeated by a hacker by spoofing their network interface card's hardware address?
Wireless access points can utilize MAC filtering to ensure only known network interface cards are allowed to connect to the network. If the hacker changes their MAC address to a trusted MAC address, they can easily bypass this security mechanism. MAC filtering is considered a good security practice as part of a larger defense-in-depth strategy, but it won't stop a skilled hacker for long. MAC addresses are permanently burned into the network interface card by the manufacturer and serve as the device's physical address
