AWS Certified Cloud Practitioner (CLF-C02) — Question 611

Which AWS network services or features allow CIDR block notation when providing an IP address range? (Choose two.)

Answer options

• A. Security groups
• B. Amazon Machine Image (AMI)
• C. Network access control list (network ACL)
• D. AWS Budgets
• E. Amazon Elastic Block Store (Amazon EBS)

Correct answer: A, C

Explanation

Security groups and Network ACLs are Amazon VPC networking features that require CIDR block notation to define IP address ranges for firewall rules. Other options like Amazon Machine Images (AMIs), AWS Budgets, and Amazon Elastic Block Store (Amazon EBS) are compute, cost management, and storage services, respectively, and do not handle IP routing or CIDR blocks.
