A company needs to reserve a certain amount of Amazon EC2 compute resources in a specific Availability Zone within an AWS Region. Which purchasing option should the company use to meet this requirement?
A
EC2 Instance Savings Plans
B
Compute Savings Plans
C
Regional Reserved Instances
D
Zonal Reserved Instances
Explanation:
Zonal Reserved Instances are the correct choice because:
Zonal Reserved Instances provide capacity reservation in a specific Availability Zone within an AWS Region
They guarantee capacity for EC2 instances in that particular Availability Zone
This is ideal when you need to ensure compute resources are available in a specific zone for compliance, performance, or architectural requirements
Why not the other options:
EC2 Instance Savings Plans and Compute Savings Plans: These provide cost savings but do not guarantee capacity reservation in specific Availability Zones
Regional Reserved Instances: These provide flexibility across Availability Zones within a region but do not guarantee capacity in any specific zone
When you need to reserve capacity in a specific Availability Zone, Zonal Reserved Instances are the appropriate AWS purchasing option.
