How does AWS describe an isolated networking environment into which you can launch compute resources while closely controlling network access? 1) Security Group 2) Virtual Private Cloud (VPC) 3) Availability Zone 4) Internet gateway

2) Virtual Private Cloud (VPC)

Which of the following best describes the cloud service model known as infrastructure as a service (Iaas)? 1) End user access to software applications delivered over the internet. 2) Access to a simplified interface through which customers can directly deploy their application code without having to worry about managing the underlying infrastructure. 3) Customer rental of the use of measured units of a provider's physical compute, storage, and networking resources. 4) Abstracted interfaces built to manage clusters of containerized workloads.

3) Customer rental of the use of measured units of a provider's physical compute, storage, and networking resources. - Rent the physical infrastructure
