CompTIA Network+ (N10-008) — Question 21

A network administrator walks into a datacenter and notices an unknown person is following closely. The administrator stops and directs the person to the security desk. Which of the following attacks did the network administrator prevent?

Answer options

• A. Evil twin
• B. Tailgating
• C. Piggybacking
• D. Shoulder surfing

Correct answer: B

Explanation

The correct answer is B, as tailgating refers to unauthorized individuals following someone with legitimate access into a secure area. The other options are incorrect because an evil twin is a type of Wi-Fi attack, piggybacking typically involves gaining access through an authorized user without their knowledge, and shoulder surfing is the act of spying on someone entering sensitive information.
