A company wants to ensure that two Amazon EC2 instances are in (CLF-C02)
A company wants to ensure that two Amazon EC2 instances are in separate data centers with minimal communication latency between the data centers.
How can the company meet this requirement?
A) Place the EC2 instances in two separate AWS Regions connected with a VPC peering connection.
B) Place the EC2 instances in two separate Availability Zones within the same AWS Region.
C) Place one EC2 instance on premises and the other in an AWS Region. Then connect them by using an AWS VPN connection.
D) Place both EC2 instances in a placement group for dedicated bandwidth.
Solution
Correct answer: B) Place the EC2 instances in two separate Availability Zones within the same AWS Region.
Availability Zones (AZs) are distinct locations within an AWS Region that are engineered to be isolated from failures in other Availability Zones. They are physically separate data centers within a region, yet are interconnected with low-latency links. By placing EC2 instances in two separate Availability Zones within the same AWS Region, the company ensures that the instances are in different data centers with minimal communication latency between them.
