CompTIA Network+ (N10-007) — Question 635

A network administrator discovered a rogue access point was sending a signal from inside the corporate headquarters. Which of the following would prevent the access point from providing access to the company's internal network?

Answer options

• A. Disabling unnecessary services
• B. Placing unused ports in a separate VLAN
• C. Enabling BPDU guard
• D. Configuring a geofence at the corporate boundary

Correct answer: B

Explanation

Isolating inactive ports in a different VLAN prevents unauthorized devices from accessing the internal network, effectively blocking the rogue access point. Disabling unnecessary services, enabling BPDU guard, and configuring a geofence do not directly address the issue of unauthorized access within the network infrastructure.
