CompTIA Cloud Essentials+ (CLO-002) — Question 23

Which of the following services would restrict connectivity to cloud resources?

Answer options

• A. Security lists
• B. Firewall
• C. VPN
• D. Intrusion detection system

Correct answer: B

Explanation

A Firewall is specifically designed to control incoming and outgoing network traffic based on predetermined security rules, thereby restricting connectivity. Security lists and VPNs also play roles in security, but they do not inherently restrict connectivity in the same direct manner as a Firewall. An Intrusion Detection System monitors and alerts on potential threats but does not restrict access itself.
