A company is moving to the AWS Cloud to reduce operational overhead for its application infrastructure.
Which IT operation will the company still be responsible for after the migration to AWS?
Explanation:
AWS Elastic Beanstalk, Amazon Aurora, and AWS Auto Scaling are managed services that reduce the operational overhead for the customers. AWS is responsible for security patching, backups, and termination of these services. However, the customers are still responsible for configuring IAM access controls to manage the permissions and policies for their AWS resources. This is part of the AWS shared responsibility model, which defines the security and compliance responsibilities of AWS and the customers. You can learn more about the AWS shared responsibility model from this whitepaper or this digital course.

Which AWS service provides storage that can be mounted across multiple Amazon EC2 instances?
Explanation:
Amazon EFS is a fully managed service that provides scalable and elastic file storage for multiple Amazon EC2 instances. Amazon EFS supports the Network File System (NFS) protocol, which allows multiple EC2 instances to access the same file system concurrently. You can learn more about Amazon EFS from this webpage or this digital course.

Which pillar of the AWS Well-Architected Framework includes the AWS shared responsibility model?
Explanation:
The AWS Well-Architected Framework is a set of best practices and guidelines for designing and operating reliable, secure, efficient, and cost-effective systems in the cloud. The framework consists of five pillars: operational excellence, performance efficiency, reliability, security, and cost optimization. The security pillar covers the AWS shared responsibility model, which defines the security and compliance responsibilities of AWS and the customers. You can learn more about the AWS Well-Architected Framework from [this whitepaper] or [this digital course].
Question 355

AWS has the ability to achieve lower pay-as-you-go pricing by aggregating usage across hundreds of thousands of users.
This describes which advantage of the AWS Cloud?
Explanation:
AWS has the ability to achieve lower pay-as-you-go pricing by aggregating usage across hundreds of thousands of users. This means that AWS can leverage its massive scale and purchasing power to reduce the costs of infrastructure, hardware, software, and operations. These savings are then passed on to the customers, who only pay for the resources they use. You can learn more about the AWS pricing model from [this webpage] or [this digital course].
Question 356
![Export Export](https://examgecko.com/assets/images/icon-download-24.png)
A company wants to use guidelines from the AWS Well-Architected Framework to limit human error and facilitate consistent responses to events.
Which of the following is a Well-Architected design principle that will meet these requirements?
Explanation:
This is a design principle of the operational excellence pillar of the AWS Well-Architected Framework. Performing operations as code means using scripts, templates, or automation tools to perform routine tasks, such as provisioning, configuration, deployment, and monitoring. This reduces human error, increases consistency, and enables faster recovery from failures. You can learn more about the operational excellence pillar from this whitepaper or this digital course.
Question 357
![Export Export](https://examgecko.com/assets/images/icon-download-24.png)
Which of the following is a benefit of using an AWS managed service?
Explanation:
This is a benefit of using an AWS managed service, such as Amazon S3, Amazon DynamoDB, or AWS Lambda. AWS managed services are fully managed by AWS, which means that AWS handles the provisioning, scaling, patching, backup, and recovery of the underlying infrastructure and software.
This reduces the operational overhead for the company's IT staff, who can focus on their core business logic and innovation. You can learn more about the AWS managed services from this webpage or this digital course.
Question 358

A company encourages its teams to test failure scenarios regularly and to validate their understanding of the impact of potential failures.
Which pillar of the AWS Well-Architected Framework does this philosophy represent?
Explanation:
This is the pillar of the AWS Well-Architected Framework that represents the philosophy of testing failure scenarios regularly and validating the understanding of the impact of potential failures. The operational excellence pillar covers the best practices for designing, running, monitoring, and improving systems in the AWS Cloud. Testing failure scenarios is one of the ways to improve the system's resilience, reliability, and recovery. You can learn more about the operational excellence pillar from this whitepaper or this digital course.
Question 359
![Export Export](https://examgecko.com/assets/images/icon-download-24.png)
Which of the following are general AWS Cloud design principles described in the AWS Well-Architected Framework?
Explanation:
These are two of the general AWS Cloud design principles described in the AWS Well-Architected Framework. Testing systems at production scale means using tools such as AWS CloudFormation, AWS CodeDeploy, and AWS X-Ray to simulate real-world scenarios and measure the performance, scalability, and availability of the system. Driving architecture design based on data means using tools such as Amazon CloudWatch, AWS CloudTrail, and AWS Config to collect and analyze metrics, logs, and events about the system and use the insights to optimize the system's design and operation. You can learn more about the AWS Well-Architected Framework from this whitepaper or [this digital course].
Question 360
![Export Export](https://examgecko.com/assets/images/icon-download-24.png)
Which scenarios represent the concept of elasticity on AWS? (Select TWO.)
Explanation:
These are two scenarios that represent the concept of elasticity on AWS. Elasticity means the ability to adjust the resources and capacity of the system in response to changes in demand or environment. Scaling the number of Amazon EC2 instances based on traffic means using services such as AWS Auto Scaling or Elastic Load Balancing to add or remove instances as the traffic increases or decreases. Resizing Amazon RDS instances as business needs change means using the Amazon
RDS console or API to modify the instance type, storage type, or storage size of the database as the workload grows or shrinks. You can learn more about the concept of elasticity on AWS from [this webpage] or [this digital course].
