What is important about the VPC sizing?

• A. The IP addresses are usually in a private range with a subnet block specifier such as 10.0.0.1/24
• B. For zero downtime deployment each worker in CloudHub needs additional IP addresses
• C. A few IPs in a VPC are reserved for infrastructure
• D. The Mule applications are deployed without dedicated IPs

Answer: (A)

When sizing a VPC, the important thing is deciding the IP address space you’ll use inside the network. This space is private by design and is defined with a CIDR block, which determines how many addresses you have available for subnets and resources. Saying the VPC uses a private range with a subnet block like 10.0.0.1/24 captures this idea: you’re planning within a private address space and a specific subnet size, which directly controls capacity and how you segment resources.

Other options focus on deployment timing or general infrastructure quirks rather than the address space plan. While some addresses may be reserved by the platform, the essence of VPC sizing is about selecting the private IP range and subnetting to meet capacity needs.
