A. B. C. D.B.
The network administrator prevented the tailgating attack. Tailgating refers to an unauthorized person following closely behind an authorized person to gain access to a secure area. The unauthorized person may pretend to be a visitor, an employee, or even a service technician to gain entry.
In this scenario, the network administrator noticed the unknown person following closely and acted accordingly by stopping the person and directing them to the security desk. This is the correct course of action to prevent the tailgating attack, which is a physical security breach that can compromise the security of a datacenter or any other secure area.
The other options given in the question are different types of attacks that can occur in a network or security setting. Evil twin refers to a wireless access point that is set up to mimic a legitimate access point, with the intent to capture sensitive information or spread malware. Piggybacking refers to the act of gaining unauthorized access to a secure area by following an authorized person without their knowledge. Shoulder surfing refers to the act of looking over someone's shoulder to gain access to sensitive information, such as passwords or other confidential data.
Therefore, in this scenario, the network administrator prevented the tailgating attack by taking the necessary steps to ensure that the unknown person did not gain access to the secure datacenter.
