• Question 325:

  A company has multiple SQL-based databases located in a data center. The company needs to migrate all database servers to the AWS Cloud to reduce the cost of operating physical servers.

  Which AWS service or resource will meet these requirements with the LEAST operational overhead?

  A. Amazon EC2 instances
  B. Amazon RDS
  C. Amazon DynamoDB
  D. OpenSearch
  B. Amazon RDS

  ---

  Explanation

  Amazon RDS (Relational Database Service) is a managed database service that simplifies the setup, operation, and scaling of relational databases in the AWS Cloud. It supports several SQL-based databases, such as MySQL, PostgreSQL,

  Oracle, SQL Server, and MariaDB, while automating common administrative tasks such as backups, patch management, and scaling. This significantly reduces operational overhead compared to managing databases on Amazon EC2

  instances, which require manual management of the operating system, database software, backups, and maintenance.

  Why Other Options Are Not Suitable:

  Amazon EC2 instances: Incorrect. Managing databases on Amazon EC2 instances involves more operational overhead, including manual management of the database server. Amazon DynamoDB: Incorrect. This is a NoSQL database

  service, which is not suitable for migrating or hosting SQL-based databases.

  OpenSearch: Incorrect. This service is designed for search and analytics workloads, not for hosting SQL-based databases.

• Question 326:

  A company is using AWS for all its IT infrastructure. The company's developers are allowed to deploy applications on their own. The developers want to deploy their applications without having to provision the infrastructure themselves Which AWS service should the developers use to meet these requirements?

  A. AWS CloudFormation
  B. AWS CodeBuild
  C. AWS Elastic Beanstalk
  D. AWS CodeDeploy
  C. AWS Elastic Beanstalk

  ---

  Explanation

  AWS Elastic Beanstalk is a fully managed service designed for developers who want to deploy and manage their applications without having to provision and manage the underlying infrastructure themselves. Developers can simply upload their code, and Elastic Beanstalk automatically handles the deployment, including provisioning the necessary resources (such as EC2 instances, load balancers, and auto-scaling).

  A. AWS CloudFormation: Incorrect, as it is an infrastructure-as-code service for defining and provisioning AWS resources but does not directly deploy applications.

  B. AWS CodeBuild: Incorrect, as it is a service for building and testing code, not for deploying applications.

  D. AWS CodeDeploy: Incorrect, as it is specifically designed for automating software deployments to a variety of compute services, including EC2, but it does not manage the underlying infrastructure.

• Question 327:

  Which AWS services or features provide disaster recovery solutions for Amazon EC2 instances? (Choose two.)

  A. EC2 Reserved Instances
  B. EC2 Amazon Machine Images (AMIs)
  C. Amazon Elastic Block Store (Amazon EBS) snapshots
  D. AWS Shield
  E. Amazon GuardDuty
  B. EC2 Amazon Machine Images (AMIs)
  C. Amazon Elastic Block Store (Amazon EBS) snapshots

  ---

  Explanation

  EC2 Amazon Machine Images (AMIs) and Amazon Elastic Block Store (Amazon EBS) snapshots are two AWS services that provide disaster recovery solutions for Amazon EC2 instances. EC2 AMIs are preconfigured templates that contain the software configuration and data required to launch an EC2 instance. You can create AMIs from your running EC2 instances and use them to launch new instances in the same or different AWS Regions. This way, you can quickly recover your EC2 instances in case of a disaster that affects your primary Region or Availability Zone. Amazon EBS snapshots are incremental backups of your Amazon EBS volumes. You can create snapshots of your volumes and store them in Amazon S3, which is a highly durable and scalable storage service. You can use snapshots to restore your volumes to a previous point in time or to create new volumes from snapshots. Snapshots can also be copied across AWS Regions, enabling you to recover your data in another Region in case of a disaster. The other options are not directly related to disaster recovery for EC2 instances: EC2 Reserved Instances are a pricing model that allows you to reserve EC2 capacity for a specific period of time and receive a discount on the hourly charge. Reserved Instances do not provide any disaster recovery benefits, as they are only a billing option.

  AWS Shield is a managed service that protects your AWS resources from distributed denial-of-service (DDoS) attacks. AWS Shield provides basic protection for all AWS customers at no additional charge, and advanced protection for customers who need higher levels of detection and mitigation. AWS Shield does not provide any disaster recovery benefits, as it is only a security service. Amazon GuardDuty is a threat detection service that monitors your AWS account and workloads for malicious or unauthorized activity. Amazon GuardDuty analyzes various data sources, such as AWS CloudTrail, Amazon VPC Flow Logs, and DNS logs, to identify potential threats and alert you via Amazon CloudWatch Events or AWS Lambda. Amazon GuardDuty does not provide any disaster recovery benefits, as it is only a monitoring service.

• Question 328:

  A company is planning to migrate to the AWS Cloud. The company is conducting organizational transformation and wants to become more responsive to customer inquiries and feedback.

  Which tasks should the company perform to meet these requirements, according to the AWS Cloud Adoption Framework (AWS CAF)? (Select TWO.)

  A. Realign teams to focus on products and value streams.
  B. Create new value propositions with new products and services.
  C. Use agile methods to rapidly iterate and evolve.
  D. Use a new data and analytics platform to create actionable insights.
  E. Migrate and modernize legacy infrastructure.
  A. Realign teams to focus on products and value streams.
  C. Use agile methods to rapidly iterate and evolve.

  ---

  Explanation

  Realigning teams to focus on products and value streams, and using agile methods to rapidly iterate and evolve are tasks that the company should perform to meet the requirements of becoming more responsive to customer inquiries and feedback, according to the AWS Cloud Adoption Framework (AWS CAF). AWS CAF organizes guidance into six areas of focus, called perspectives: business, people, governance, platform, security, and operations. Each perspective is divided into capabilities, which describe the skills and processes to execute the transition effectively. The people perspective helps you prepare your organization for cloud adoption, and includes capabilities such as organizational change management, staff skills and readiness, and organizational alignment. The business perspective helps you align IT strategy with business strategy, and includes capabilities such as business case development, value proposition, and product ownership. Creating new value propositions with new products and services is a task that belongs to the business perspective, but it is not directly related to the requirement of becoming more responsive to customer inquiries and feedback. Using a new data and analytics platform to create actionable insights is a task that belongs to the platform perspective, which helps you design, implement, and optimize the architecture of the AWS environment. However, it is also not directly related to the requirement of becoming more responsive to customer inquiries and feedback. Migrating and modernizing legacy infrastructure is a task that belongs to the operations perspective, which helps you enable, run, use, operate, and recover IT workloads to the level agreed upon with your business stakeholders. However, it is also not directly related to the requirement of becoming more responsive to customer inquiries and feedback.
