B.
Create an On-Demand Capacity Reservation that specifies the Region needed.
C.
Purchase Reserved Instances that specify the Region and three Availability Zones needed.
D.
Create an On-Demand Capacity Reservation that specifies the Region and three Availability Zones needed.
A and C are out; reserved instances need min 1 year
https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-capacity-reservations.html:
"When you create a Capacity Reservation, you specify:
The Availability Zone in which to reserve the capacity"
D is the answer
yeah D. On your AWS Free Trial, go to EC2 -> Instances -> Capacity Reservations -> Create Capacity Reservation and there you can see the field for Availability Zone.
https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-capacity-reservations.html: is the answer
To me keyword is 1 week as reserved instances need minimum 1 year
Answer is D.
Answer A is wrong because of url:
https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-reserved-instances.html
You can purchase a Reserved Instance for a one-year or three-year commitment, with the three-year commitment offering a bigger discount.
One-year: A year is defined as 31536000 seconds (365 days).
Three-year: Three years is defined as 94608000 seconds (1095 days).
Answer is D.
Details are revealed in url:
When you create a Capacity Reservation, you specify:
The Availability Zone in which to reserve the capacity
The number of instances for which to reserve capacity
The instance attributes, including the instance type, tenancy, and platform/OS
