CompTIA Network+ (N10-007) — Question 393

Employees at a company report that they are unable to access the Internet. A network technician notices the workstations are receiving IP addresses that do not follow the IP addressing scheme of the corporate network. Upon further inspection, the technician finds an employee has plugged a rogue wireless router into the corporate network. Which of the following settings would have prevented this situation?

Answer options

Correct answer: A

Explanation

DHCP snooping helps to prevent unauthorized DHCP servers from providing IP addresses, thereby ensuring that only legitimate devices can assign IPs within the network. Other options like DHCP relay, leasing, and options do not directly address the security concern of rogue devices providing incorrect IP addresses.
