Which AWS network services or features allow CIDR block notation when providing an IP address range?
(Choose two.)
Security groups
Amazon Machine Image (AMI)
Network access control list (network ACL)
AWS Budgets
Amazon Elastic Block Store (Amazon EBS)
Explanations:
Security groups act as virtual firewalls for your EC2 instances. You define rules that specify allowed inbound and outbound traffic. These rules can use CIDR block notation to define IP address ranges.
An Amazon Machine Image (AMI) is a template for creating EC2 instances. It does not involve specifying IP address ranges or using CIDR blocks.
Network access control lists (network ACLs) are stateless firewalls that operate at the subnet level. They control traffic entering and leaving subnets and use CIDR block notation to define IP address ranges in their rules.
AWS Budgets allows you to set custom budgets and receive alerts when your costs or usage exceed your budgeted amounts. It is not related to networking or IP addressing.
Amazon Elastic Block Store (Amazon EBS) provides block storage volumes for use with EC2 instances. It does not involve specifying IP address ranges or using CIDR blocks.
From my perspective, the answer is:
