CompTIA Network+ (N10-008) — Question 804

A network manager is configuring switches in IDFs to ensure unauthorized client computers are not connecting to a secure wired network. Which of the following is the network manager MOST likely performing?

Answer options

• A. Disabling unneeded switchports
• B. Changing the default VLAN
• C. Configuring DHCP snooping
• D. Writing ACLs to prevent access to the switch

Correct answer: A

Explanation

The correct answer is A, as disabling unneeded switchports helps to physically prevent unauthorized devices from connecting to the network. Options B, C, and D may enhance security but do not directly prevent unauthorized devices from connecting in the same way that disabling ports does.
