<span>A profile is made the first occasion when that a client sign on
to a Windows XP, Windows 2000, or Windows NT® Workstation–based PC. A client
profile is a gathering of settings and documents that characterizes the
condition that the framework loads when a client sign on. It incorporates all
the client arrangement settings, for example, program things, screen hues,
organize associations, printer associations, mouse settings, and window size
and position. Profiles are not client arrangements and the client has a profile
regardless of the possibility that you don't utilize Group Policy.</span>
Answer:
4. A Denial of Service attack (DDOS attack).
Explanation:
A DDOS attack is a malicious attempt to disrupt the normal traffic to a service.
In essence, it sends an enormous amount of requests to the service, until the server is overwhelmed because it can't handle that much traffic, and collapses in an overflow.
Thus, regular users are not able to access their services.
Usually, attackers use a botnet, a network of "zombie" computers that have been previously infected with a malware that allows the attacker to remotely control them, then the botnet starts to send a flood of traffic from different locations, and make the attacker difficult to detect or track.
