AWS Practice Test

Question 1

If you deploy your workloads over different Availability Zones in AWS and use Amazon RDS Multi-AZ, which of 
the following cloud architectural principles are followed?

Accepted Answer

Design for failure

Answer

Deploying workloads across different Availability Zones (AZs) and utilizing Amazon RDS Multi-AZ are key strategies for building highly available and fault-tolerant architectures. This approach ensures that if one AZ experiences an outage, your application and database can seamlessly failover to resources in another AZ, adhering to the cloud architectural principle of 'Design for failure'.

Question 2

Which AWS service should you use to centrally manage rules and billing across different accounts?

Accepted Answer

AWS Organizations

Answer

For high availability and fault tolerance, it is recommended to deploy an Application Load Balancer (ALB) across at least two Availability Zones. This configuration ensures that if one Availability Zone becomes unavailable, the ALB can continue to route traffic to healthy instances in the other active Availability Zone, maintaining application uptime.

Question 3

An international bank intends to move some of its on-premises online programs to Amazon Web Services (AWS).
 Which of the following is a benefit of adopting Amazon Web Services (AWS) instead of virtualized data centers?

Accepted Answer

Lower variable costs and lower upfront costs.

Answer

The AWS Total Cost of Ownership (TCO) Calculator is a valuable tool for estimating the cost savings of migrating on-premises workloads to AWS. It allows organizations to compare the costs of running their infrastructure in their own data centers versus on AWS, providing a clear financial justification for cloud adoption. This helps in planning and budgeting for a hybrid cloud architecture.

Question 4

To design a highly available architecture, choose the minimal number of Availability Zones for your Application Load Balancer.

Accepted Answer

2

Answer

For high availability, AWS recommends deploying Application Load Balancers (ALBs) across at least two Availability Zones. This ensures that if one Availability Zone experiences an outage, the ALB can continue to route traffic to healthy instances in other Availability Zones, maintaining application uptime and resilience.

Question 5

A corporation intends to use AWS to implement a hybrid cloud architecture. Which of the following methods may they 
use to estimate their costs? (Choose TWO)

Accepted Answer

AWS Total Cost of Ownership (TCO) Calculator

Answer

The AWS Total Cost of Ownership (TCO) Calculator is a crucial tool for estimating the cost savings of migrating on-premises workloads to AWS. It allows businesses to compare the expenses of running their infrastructure in their own data centers versus on AWS, providing a clear financial justification for cloud adoption. This helps in planning and budgeting for a hybrid cloud architecture.
