A user wants the ability to easily scale compute resources in and out, while only paying for the resources used.
Which benefit of the AWS Cloud should the user take advantage of?
A. Elasticity
B. Fault tolerance
C. Durability
D. High availability
Elasticity In the AWS Cloud, compute resources are elastic, which means that they can quickly scale to match the requirements of a specific application. Elasticity gives you the ability to match the supply of resources to demand, which gives you the ability to scale compute resources based on demand.
A company is starting its migration to the AWS Cloud. The company wants to use AWS experience and best practices to help ensure its success in moving to the AWS Cloud. The company wants a combination of business-oriented and technical points of view.
Which AWS service or guidance will meet these requirements?
A. AWS Well-Architected Framework
B. AWS Control Tower
C. AWS Cloud Adoption Framework (AWS CAF)
D. AWS Trusted Advisor
AWS Well-Architected Framework The Well-Architected Framework helps cloud architects to build secure, efficient, high-performing, and resilient infrastructures on AWS. The Well-Architected Framework is primarily focused on the technical point of view, rather than a combination of technical and business points of view.
What are the benefits of developing and running a new application in the AWS Cloud compared to on-premises? (Select TWO.)
A. AWS automatically distributes the data globally for higher durability
B. AWS operates the application
C. AWS provides options to architect for high availability
D. AWS can scale resources of changing application demands
E. AWS patches user applications
AWS provides options to architect for high availability By providing multiple Availability Zones within an AWS Region, AWS provides a highly available infrastructure platform for architecting new applications.
AWS can scale resources of changing application demands By providing an elastic method to provision the right amount of computing resources for your application demand, AWS gives you the ability to focus more on the application and less on its capacity.
Which AWS service provides a secure, fast, and cost-effective way to migrate petabyte-scale datasets from on-premises into AWS?
A. AWS Database Migration Service (AWS DMS)
B. AWS Snowball Edge
C. AWS Migration Hub
D. AWS Schema Conversion Tool (AWS SCT)
Snowball Edge is a device that can migrate petabyte-scale datasets at fast speed. Snowball Edge devices also have onboard compute capabilities. You can use Snowball Edge to migrate petabyte-scale datasets from on-premises to AWS in a cost-effective way.
A company that operates in the AWS Cloud wants to test workloads and team responses to simulated events. The company will conduct an exercise to identify potential issues that need to be addressed.
Which design principle of the AWS Well-Architected Framework does this exercise represent?
A. Anticipate failure
B. Automatically recover from failure
C. Measure overall cost efficiency
D. Implement loosely coupled dependencies
Anticipate failure is a principle of the operational excellence pillar of the Well-Architected Framework. To anticipate failure, you can perform test exercises to identify potential sources of failure.
Which of the following is an advantage of AWS Cloud computing?
A. Trade security for elasticity.
B. Trade operational excellence for agility.
C. Trade fixed expenses for variable expenses.
D. Trade elasticity for performance.
Trade fixed expenses for variable expenses An advantage of the AWS Cloud is to trade fixed expenses for variable expenses. With the AWS Cloud, you only pay for what you use. Therefore, you can move away from fixed expenses. With fixed expenses, you pay upfront, regardless of whether you use the full capacity. For example, to maintain your own data centers and servers would be a fixed expense.
A company has an application that has dependencies between its underlying components. When one component fails, the entire application fails.
Which AWS Cloud design principle should be applied to address the current weakness of the application?
A. Implement elasticity, which enables the application to scale up or scale down as demand changes
B. Enable several Amazon EC2 instances to run in parallel to achieve better performance
C. Decouple components by isolating them and ensuring that individual components can function when other components fail
D. Double Amazon EC2 computing resources to increase system fault tolerance
Decouple components by isolating them and ensuring that individual components can function when other components fail. You can decouple an application into component applications, or microservices, to isolate parts of the application. A failure in a component does not cause a failure of the entire application. This solution also presents opportunities to scale the subcomponents independently.
A company wants help to design a new cloud content-management application using AWS best practices.
Which service or tool should provide guidance?
A. AWS AppSync
B. AWS AppConfig
C. AWS Well-Architected Tool
D. Amazon Inspector
AWS Well-Architected Tool. AWS WA Tool is used to improve your architecture using AWS best practices. The AWS WA Tool can provide guidance on architecture design for a new application.
What are valid AWS Cloud Adoption Framework (AWS CAF) perspectives? (Select TWO.)
A. Performance efficiency
B. Sustainability
C. Cost optimization
D. Governance
E. Platform
Governance. The governance perspective is one of the six AWS CAF perspectives.
Platform. The platform perspective is one of the six AWS CAF perspectives.
Which concept in the AWS Cloud value proposition is an example of the ability to horizontally scale Amazon EC2 instances based on demand?
A. Economies of scale
B. Elasticity
C. High availability
D. Agility
Elasticity. Elasticity is the ability to scale your infrastructure based on changes in user demand.
A company has on-premises compute resources that are fully utilized at the end of each month. However, during the remainder of the month, those resources are underutilized.
Which AWS Cloud benefit would BEST address this issue?
A. High availability
B. Elasticity
C. Security
D. Loose coupling
Elasticity. The AWS Cloud gives you the ability to stop planning capacity and let it automatically scale up when needed and scale down as demand goes down. This elasticity could stop you from having underutilized resources.
A company needs to move an on-premises IBM Db2 database to the AWS Cloud. The company wants to convert the database to a fully managed Amazon Aurora database.
Which AWS services or features can the company use to analyze, synchronize, deploy, and monitor the conversion of the database? (Select TWO.)
A. AWS Database Migration Service (AWS DMS)
B. Amazon S3 File Gateway
C. AWS DataSync
D. AWS Schema Conversion Tool (AWS SCT)
E. AWS Direct Connect
AWS Database Migration Service (AWS DMS). You can use AWS DMS to migrate databases between sources, including between on premises and the cloud.
AWS Schema Conversion Tool (AWS SCT). You can use AWS SCT to convert an existing database schema from one database engine to another.
Which on-premises expense will be eliminated if the company migrates their entire application to Amazon EC2?
A. Server hardware costs
B. Licensing costs
C. Storage backup costs
D. Costs of transferring data to the internet
Server hardware costs. Server hardware costs are included in EC2 instance costs.
A company wants to migrate its application to AWS. The company wants to replace upfront expenses with variable payment that is based on usage.
What should the company do to meet these requirements?
A. Use pay-as-you-go pricing.
B. Purchase Reserved Instances.
C. Pay less by using more.
D. Rightsize instances.
Use pay-as-you-go pricing. AWS offers pay-as-you-go pricing for more than 200 cloud services. Pay-as-you-go pricing requires no upfront payments, and you only pay for what you use.
Which pillar of the AWS Well-Architected Framework has the design principle “perform operations as code”?
A. Performance efficiency
B. Operational excellence
C. Reliability
D. Security
Operational Excellence. The principle to perform operations as code is a design principle of the operational excellence pillar. By performing operations as code, you limit human error and enable consistent responses to events.
