What is the scope of a VPC within the AWS network?
A VPC can span all Availability Zones globally.
A VPC must span at least two subnets in each AWS Region.
A VPC must span at least two edge locations in each AWS Region.
A VPC can span all Availability Zones within an AWS Region.
Explanations:
A VPC is limited to a single AWS Region and cannot span across multiple regions or Availability Zones globally.
A VPC can be created with a single subnet; it is not required to span at least two subnets.
Edge locations are used for content delivery and do not relate to the scope of a VPC, which is tied to AWS Regions and Availability Zones.
A VPC can span all Availability Zones within a single AWS Region, allowing resources to be distributed for high availability.
I weigh that the answer is:
A VPC can span all Availability Zones within an AWS Region.
