  *On-Demand Instances ?Pay, by the second, for the instances that you launch. *Savings Plans ?Reduce your Amazon EC2 costs by making a commitment to a consistent amount of usage, in USD per hour, for a term of 1 or 3 years.

  *Reserved Instances ?Reduce your Amazon EC2 costs by making a commitment to a consistent instance configuration, including instance type and Region, for a term of 1 or 3 years.

  *Spot Instances ?Request unused EC2 instances, which can reduce your Amazon EC2 costs significantly.

  *Dedicated Hosts ?Pay for a physical host that is fully dedicated to running your instances, and bring your existing per-socket, per-core, or per-VM software licenses to reduce costs. *Dedicated Instances ?Pay, by the hour, for instances that

  run on single-tenant hardware. *Capacity Reservations ?Reserve capacity for your EC2 instances in a specific Availability Zone for any duration. If you require a capacity reservation, purchase Reserved Instances or Capacity Reservations for

  a specific Availability Zone. Spot Instances are a cost-effective choice if you can be flexible about when your applications run and if they can be interrupted. Dedicated Hosts or Dedicated Instances can help you address compliance

  requirements and reduce costs by using your existing server-bound software licenses.

• Question 233:

  Which AWS service helps developers use loose coupling and reliable messaging between microservices?

  A. Elastic Load Balancing
  B. Amazon Simple Notification Service (Amazon SNS)
  C. Amazon CloudFront
  D. Amazon Simple Queue Service (Amazon SQS)
  D. Amazon Simple Queue Service (Amazon SQS)

  ---

  Explanation

  Amazon Simple Queue Service (Amazon SQS) is a service that provides fully managed message queues for asynchronous communication between microservices. It helps developers use loose coupling and reliable messaging by allowing them to send, store, and receive messages between distributed components without losing them or requiring each component to be always available1. Elastic Load Balancing is a service that distributes incoming traffic across multiple targets, such as Amazon EC2 instances, containers, and IP addresses. Amazon Simple Notification Service (Amazon SNS) is a service that provides fully managed pub/sub messaging for event-driven and push-based communication between microservices. Amazon CloudFront is a service that provides a fast and secure content delivery network (CDN) for web applications.

• Question 234:

  A company has a workload that will run continuously for 1 year. The workload cannot tolerate service interruptions. Which Amazon EC2 purchasing option will be MOST cost-effective?

  A. All Upfront Reserved Instances
  B. Partial Upfront Reserved Instances
  C. Dedicated Instances
  D. On-Demand Instances
  A. All Upfront Reserved Instances

  ---

  Explanation

  All Upfront Reserved Instances offer the most cost-effective solution for a workload that will run continuously for one year without interruption. By paying upfront, the user receives the maximum discount compared to the On-Demand pricing model. Partial Upfront Reserved Instances and Dedicated Instances are more expensive than All Upfront Reserved Instances. On-Demand Instances are not cost-effective for continuous, long-term workloads due to their higher hourly rates.

• Question 235:

  Which aspect of security is the customer's responsibility, according to the AWS shared responsibility model?

  A. Patch and configuration management
  B. Service and communications protection or zone security
  C. Physical and environmental controls
  D. Awareness and training
  A. Patch and configuration management

  ---

  Explanation

  According to the AWS shared responsibility model, AWS is responsible for the security of the cloud, while the customer is responsible for the security in the cloud. This means that AWS provides the physical and environmental controls, the service and communications protection, and the awareness and training for its employees, while the customer provides the patch and configuration management, the identity and access management, the data encryption, and the firewall configuration for its resources3.

• Question 236:

  A company has a fleet of cargo ships. The cargo ships have sensors that collect data at sea, where there is intermittent or no internet connectivity. The company needs to collect, format, and process the data at sea and move the data to AWS

  Which AWS service should the company use to meet these requirements?

  A. AWS IoT Core
  B. Amazon Lightsail
  C. AWS Storage Gateway

• Question 238:

  A company wants to migrate its on-premises infrastructure to the AWS Cloud. Which advantage of cloud computing will help the company reduce upfront costs?

  A. Go global in minutes
  B. Increase speed and agility
  C. Benefit from massive economies of scale
  D. Trade fixed expense for variable expense
  D. Trade fixed expense for variable expense

  ---

  Explanation

  One of the key advantages of cloud computing is the ability to trade fixed expenses (like data centers and physical servers) for variable expenses. With AWS, companies pay only for the compute power, storage, and other resources they use,

  rather than investing heavily in on-premises infrastructure upfront. This reduces capital expenditure and helps lower overall costs.

  Why other options are not suitable:

  A. Go global in minutes: Refers to the ability to quickly deploy applications around the world, but does not directly reduce upfront costs.

  B. Increase speed and agility: Refers to the ability to quickly scale and deploy resources, but is not directly related to cost reduction.

  C. Benefit from massive economies of scale: Refers to AWS's ability to lower costs by leveraging its scale, but the primary advantage for reducing upfront costs is moving from fixed to variable expenses.

• Question 239:

  A company needs a hybrid cloud storage service to connect its on-premises environment to scalable AWS Cloud storage. Which AWS service will meet these requirements?

  A. Amazon S3
  B. Amazon FSx
