Elasticity in the AWS Cloud refers to which of the following?
(Choose two.)
How quickly an Amazon EC2 instance can be restarted
The ability to rightsize resources as demand shifts
The maximum amount of RAM an Amazon EC2 instance can use
The pay-as-you-go billing model
How easily resources can be procured when they are needed
Explanations:
Elasticity in AWS is not about how quickly an EC2 instance can be restarted; it focuses on the ability to scale resources dynamically based on demand.
This option correctly describes elasticity as it refers to the ability to rightsize resources (scale up or down) as demand fluctuates.
The maximum amount of RAM an EC2 instance can use pertains to instance types and limits, not to the concept of elasticity.
The pay-as-you-go billing model relates to cost management rather than elasticity, which is about scaling resources based on demand.
This option is correct as it reflects the ease of provisioning resources in the cloud when needed, which is a key aspect of elasticity.
