• Question 145:

  Which AWS service should a company use to create a serverless work ow?

  A. Amazon Connect

  B. AWS Lambda

  C. AWS Step Functions

  D. Amazon Elastic Block Store (Amazon EBS)

  E. AWS CodeBuild

  Correct Answer: C

  AWS Step Functions is the AWS service that provides serverless workflow orchestration. With Step Functions, you can coordinate multiple AWS services into serverless workflows, or state machines, to build applications with greater speed and agility. This service enables you to create complex, multi-step workflows that include conditional branching, error handling, and wait states.

  On the other hand, Amazon Connect is a cloud-based contact center solution that you can use to manage customer interactions across various communication channels like voice, chat, and email. AWS Lambda is a compute service that lets you run code without provisioning or managing servers, and AWS CodeBuild is a fully-managed continuous integration service that can be used to compile, test, and deploy source code. Amazon Elastic Block Store (Amazon EBS) provides block-level storage volumes for use with Amazon EC2 instances.

• Question 146:

  A company is developing an application that the company will host on Amazon EC2 instances. The application must be available 24 hours a day, 7 days a week. The company needs a scalable, highly available cloud architecture to support the application.

  Which guidelines should the company apply in its design to meet these requirements? (Choose two.)

  A. Use EC2 Spot Instances

  B. Use Multi-AZ deployments.

  C. Use Auto Scaling groups

  D. Use AWS Backup.

  E. Use EC2 Reserved Instances.

  Correct Answer: BD

  B. Use Multi-AZ deployments.

  C. Use Auto Scaling groups

  B. Use Multi-AZ deployments: Multi-AZ deployments allow the company to run the application across multiple availability zones within a region. This provides high availability and automatic failover in the event of a failure in one availability zone.

  C. Use Auto Scaling groups: Auto Scaling groups allow the company to automatically add or remove Amazon EC2 instances based on the demand for the application, which is important for ensuring high availability and scalability.

  A. Use EC2 Spot Instances: EC2 Spot Instances can be used for cost optimization, but it is not recommended for highly available workloads since it can be interrupted by the provider based on the current market price.

  D. Use AWS Backup: AWS Backup is a good practice for data protection and disaster recovery, but it is not related to high availability and scalability.

  E. Use EC2 Reserved Instances: EC2 Reserved Instances are a cost-saving option, but they are not related to high availability and scalability.

It also allows you to share the file system across multiple Availability Zones, making it ideal for applications that need to maintain high availability.

  B. Amazon S3: Amazon S3 is a fully managed object storage service that is designed to store and retrieve large amounts of data. It is not a file system and cannot be mounted on multiple instances simultaneously. C. Amazon Elastic Block Store (Amazon EBS): Amazon Elastic Block Store (Amazon EBS) is a block-level storage service that provides persistent storage for Amazon EC2 instances. It is not a file system and can only be attached to one EC2 instance at a time.

  D. Amazon FSx for Windows File Server: Amazon FSx for Windows File Server is a fully managed native Microsoft Windows file system that is built on Windows Server. Cannot be mounted on Linux instances.

• Question 149:

• Question 150:

  A company wants to run Amazon EC2 instances in locations that are near the company's global users. Which aspect of the AWS environment will support this requirement?

  A. Availability Zone

  B. Edge locations

  C. AWS Regions

  D. Regional edge caches

  Correct Answer: C

  Edge locations are used by Amazon CloudFront for content delivery and do not directly impact the location of EC2 instances.

  On the other hand, AWS Regions can support the requirement of running EC2 instances in locations that are near the company's global users. AWS Regions are separate geographical areas where AWS services, such as EC2 instances, are available. By choosing an AWS Region that is geographically close to the users, the company can reduce latency and improve performance.
