   • By having no responsibility for third-party license costs
   • By having no operational expenditures
   • By having AWS manage applications
   Explanation
   AWS helps you reduce Total Cost of Ownership (TCO) by reducing the need to invest in large capital expenditures and providing a pay-as-you-go model that empowers you to invest in the capacity you need and use it only when the business requires it.

5. Which activity is a customer responsibility in the AWS Cloud according to the AWS shared responsibility model?

   • Ensuring network connectivity from AWS to the internet
   • Patching and fixing flaws within the AWS Cloud infrastructure
   • Ensuring the physical security of cloud data centers
   • Ensuring Amazon EBS volumes are backed up

6. What are the advantages of the AWS Cloud? (Choose two.)

   • Fixed rate monthly cost
   • No need to guess capacity requirements
   • Increased speed to market
   • Increased upfront capital expenditure
   • Physical access to cloud data centers

7. When comparing the total cost of ownership (TCO) of an on-premises infrastructure to a cloud architecture, what costs should be considered? (Choose two.)

   • The credit card processing fees for application transactions in the cloud.
   • The cost of purchasing and installing server hardware in the on-premises data.
   • The cost of administering the infrastructure, including operating system and software installations, patches, backups, and recovering from failures.
   • The costs of third-party penetration testing.
   • The advertising costs associated with an ongoing enterprise-wide campaign.

8. Which AWS feature allows a company to take advantage of usage tiers for services across multiple member accounts?

   • Service control policies (SCPs)
   • Consolidated billing
   • All Upfront Reserved Instances
   • AWS Cost Explorer

9. What is one of the customer’s responsibilities according to the AWS shared responsibility model?

   • Virtualization infrastructure
   • Network infrastructure
   • Application security
   • Physical security of hardware

10. What helps a company provide a lower latency experience to its users globally?

    • Using an AWS Region that is central to all users
    • Using a second Availability Zone in the AWS Region that is using used
    • Enabling caching in the AWS Region that is being used
    • Using edge locations to put content closer to all users

11. How can the AWS Cloud increase user workforce productivity after migration from an on-premises data center?

    • Users do not have to wait for infrastructure provisioning.
    • The AWS Cloud infrastructure is much faster than an on-premises data center infrastructure.
    • AWS takes over application configuration management on behalf of users.
    • Users do not need to address security and compliance issues.

12. Which AWS service provides a quick and automated way to create and manage AWS accounts?

    • AWS QuickSight
    • Amazon Lightsail
    • AWS Organizations
    • Amazon Connect

13. Which Amazon RDS feature can be used to achieve high availability?

    • Multiple Availability Zones
    • Amazon Reserved Instances
    • Provisioned IOPS storage
    • Enhanced monitoring
    Explanation:
    Amazon RDS provides high availability and failover support for DB instances using Multi-AZ deployments. Amazon RDS uses several different technologies to provide failover support. Multi-AZ deployments for Oracle, PostgreSQL, MySQL, and MariaDB DB instances use Amazon’s failover technology. SQL Server DB instances use SQL Server Database Mirroring (DBM).

14. Where should users report that AWS resources are being used for malicious purposes?

    • AWS Abuse team
    • AWS Shield
    • AWS Support
    • AWS Developer Forums

15. Which AWS service needs to be enabled to track all user account changes within the AWS Management Console?

    • AWS CloudTrail
    • Amazon Simple Notification Service (Amazon SNS)
    • VPC Flow Logs
    • AWS CloudHSM
    Explanation:
    AWS CloudTrail is a service that enables governance, compliance, operational auditing, and risk auditing of your AWS account. With CloudTrail, you can log, continuously monitor, and retain account activity related to actions across your AWS infrastructure. CloudTrail provides event history of your AWS account activity, including actions taken through the AWS Management Console, AWS SDKs, command line tools, and other AWS services. This event history simplifies security analysis, resource change tracking, and troubleshooting. In addition, you can use CloudTrail to detect unusual activity in your AWS accounts. These capabilities help simplify operational analysis and troubleshooting.

16. What is an AWS Cloud design best practice?

    • Tight coupling of components
    • Single point of failure
    • High availability
    • Overprovisioning of resources

17. Which of the following is an example of how moving to the AWS Cloud reduces upfront cost?

    • By replacing large variable costs with lower capital investments
    • By replacing large capital investments with lower variable costs
    • By allowing the provisioning of compute and storage at a fixed level to meet peak demand
    • By replacing the repeated scaling of virtual servers with a simpler fixed-scale model
    Explanation:
    AWS does not require minimum spend commitments or long-term contracts. You replace large upfront expenses with low variable payments that only apply to what you use. With AWS you are not bound to multi-year agreements or complicated licensing models.

18. When designing a typical three-tier web application, which AWS services and/or features improve availability and reduce the impact failures? (Choose two.)

    • AWS Auto Scaling for Amazon EC2 instances
    • Amazon VPC subnet ACLs to check the health of a service
    • Distributed resources across multiple Availability Zones
    • AWS Server Migration Service (AWS SMS) to move Amazon EC2 instances into a different Region
    • Distributed resources across multiple AWS points of presence

19. Which cloud design principle aligns with AWS Cloud best practices?

    • Create fixed dependencies among application components
    • Aggregate services on a single instance
    • Deploy applications in a single Availability Zone
    • Distribute the compute load across multiple resources
    Explanation:
    Use load balancing for offloading encryption termination (TLS) to improve performance and to manage and route traffic effectively. Distribute traffic across multiple resources or services to allow your workload to take advantage of the elasticity that AWS provides.
