• Question 133:

  A company wants a cost-effective option when running its applications in an Amazon EC2 instance for short time periods. The applications can be interrupted. Which EC2 instance type will meet these requirements?

  A. Spot Instances
  B. On-Demand Instances
  C. Reserved Instances
  D. Dedicated Instances
  A. Spot Instances

  ---

  Explanation

  Spot Instances provide a cost-effective option for running Amazon EC2 instances for workloads that can tolerate interruptions. They allow you to use unused EC2 capacity in the AWS Cloud at a discounted price, making them suitable for applications that are flexible in terms of start and stop times. On-Demand Instances are more expensive and do not provide discounts for short-term, interruptible workloads, while Reserved and Dedicated Instances are for long-term or specific hardware needs.

• Question 134:

  A company needs to securely store important credentials that an application uses to connect users to a database.

  Which AWS service can meet this requirement with the MINIMAL amount of operational overhead?

  A. AWS Key Management Service (AWS KMS)
  B. AWS Config
  C. AWS Secrets Manager
  D. Amazon GuardDuty
  C. AWS Secrets Manager

  ---

  Explanation

  AWS Secrets Manager is a service that helps you protect secrets needed to access your applications, services, and IT resources. You can use AWS Secrets Manager to store, rotate, and retrieve database credentials, API keys, and other secrets throughout their lifecycle. AWS Secrets Manager eliminates the need to hardcode sensitive information in plain text, and reduces the risk of unauthorized access or leakage. AWS Secrets Manager also integrates with other AWS services, such as AWS Lambda, Amazon RDS, and AWS CloudFormation, to simplify the management of secrets across your environment

• Question 136:

  A company is collecting user behavior patterns to identify how to meet goals for sustainability impact.

  Which guidelines are best practices for the company to implement to meet these goals? (Select TWO.)

  A. Scale infrastructure with user load.
  B. Maximize the geographic distance between workloads and user locations.
  C. Eliminate creation and maintenance of unused assets.
  D. Scale resources with excess capacity and remove auto scaling.
  E. Scale infrastructure based on the number of users.
  A. Scale infrastructure with user load.
  C. Eliminate creation and maintenance of unused assets.

  ---

  Explanation

  To meet the goals for sustainability impact, the company should follow the best practices of scaling infrastructure with user load and eliminating creation and maintenance of unused assets. Scaling infrastructure with user load means adjusting the capacity of the infrastructure to match the demand of the users, which can reduce the energy consumption and carbon footprint of the system. Eliminating creation and maintenance of unused assets means avoiding the waste of resources and money on assets that are not needed or used, which can also improve the environmental and economic efficiency of the system3.

• Question 137:

  Which AWS Cloud benefit describes the ability to acquire resources as they are needed and release resources when they are no longer needed?

  A. Economies of scale
  B. Elasticity
  C. Agility
  D. Security
  B. Elasticity

  ---

  Explanation

  The AWS Cloud benefit that describes the ability to acquire resources as they are needed and release resources when they are no longer needed is elasticity. Elasticity means that users can quickly add and remove resources to match the demand of their applications, and only pay for what they use. Elasticity enables users to handle unpredictable workloads, reduce costs, and improve performance1. Economies of scale, agility, and security are other benefits of the AWS Cloud, but they do not describe the specific ability of acquiring and releasing resources on demand.

AWS Batch enables developers, scientists, and engineers to easily and efficiently run hundreds of thousands of batch computing jobs on AWS. AWS Batch dynamically provisions the optimal quantity and type of compute resources (e.g., CPU or memory- optimized instances) based on the volume and specific resource requirements of the batch jobs submitted. With AWS Batch, there is no need to install and manage batch computing software or server clusters that you use to run your jobs, allowing you to focus on analyzing results and solving problems. AWS Batch plans, schedules, and runs your batch computing workloads across the full range of AWS compute services and features, such as Amazon EC2 and Spot Instances.
