Answers
C.
Create two VPCs in two separate zones and setup failover with ELB such that if one VPC fails it will divert traffic to another VPC.
D.
Create VPC with only one private subnet and launch instances in different AZs using that subnet.
Answers
D.
Create VPC with only one private subnet and launch instances in different AZs using that subnet.
Suggested answer: A

Explanation:

A Virtual Private Cloud (VPC) is a virtual network dedicated to the user's AWS account. It enables the user to launch AWS resources into a virtual network that the user has defined. The VPC is always specific to a region. The user can create a VPC which can span multiple Availability Zones by adding one or more subnets in each Availability Zone. Each subnet must reside entirely within one Availability Zone and cannot span across zones.
