Three questions from the bank, open to read.
Which feature adds elasticity to Amazon EC2 instances to handle the changing demand for workloads?
- Resource groups
- Lifecycle policies
- Application Load Balancer
- Amazon EC2 Auto Scaling ✓ (correct)
Why this is correct
- Support for monitoring the health of each service independently, as health checks are defined at the target group level and many CloudWatch metrics are reported at the target group level. - Attaching a target group to an Auto Scaling group enables you to scale each service dynamically based on demand. Reference: https://docs.aws.amazon.com/elasticloadbalancing/latest/application/introduction.html
Why should a company choose AWS instead of a traditional data center?
- AWS provides users with full control over the underlying resources
- AWS does not require long-term contracts and provides a pay-as-you-go model ✓ (correct)
- AWS offers edge locations in every country, supporting global reach
- AWS has no limits on the number of resources that can be created
Why this is correct
- AWS offers you a pay-as-you-go approach for pricing for over 160 cloud services. - With AWS you pay only for the individual services you need, for as long as you use them, and without requiring long-term contracts or complex licensing. - AWS pricing is similar to how you pay for utilities like water and electricity. - You only pay for the services you consume, and once you stop using them, there are no additional costs or termination fees.

Why is AWS more economical than traditional data centers for applications with varying compute workloads?
- Amazon Elastic Compute Cloud (Amazon EC2) costs are billed on a monthly basis
- Customers retain full administrative access to their Amazon EC2 instances
- Amazon EC2 instances can be launched on-demand when needed ✓ (correct)
- Customers can permanently run enough instances to handle peak workloads
Why this is correct
- The ability to launch instances on-demand when needed allows customers launch and terminate instances in response to a varying workload. - This is a more economical practice than purchasing enough on-premises servers to handle the peak load.
