• Question 941:

  Which of the following are benefits that a company receives when it moves an on-premises production workload to AWS? (Select TWO.)

  A. AWS trains the company's staff on the use of all the AWS services.
  B. AWS manages all security in the cloud.
  C. AWS offers free support from technical account managers (TAMs).
  D. AWS offers high availability.
  E. AWS provides economies of scale.
  D. AWS offers high availability.
  E. AWS provides economies of scale.

  ---

  Explanation

  The correct answers are D and E because AWS offers high availability and AWS provides economies of scale are benefits that a company receives when it moves an on-premises production workload to AWS. High availability means that AWS has a global infrastructure that allows customers to deploy their applications and data across multiple regions and availability zones. This increases the fault tolerance and resilience of their applications and reduces the impact of failures. Economies of scale means that AWS can achieve lower variable costs than customers can get on their own. This allows customers to pay only for the resources they use and scale up or down as needed. The other options are incorrect because they are not benefits that a company receives when it moves an on- premises production workload to AWS. AWS trains the company's staff on the use of all the AWS services is not a benefit that a company receives when it moves an on-premises production workload to AWS. AWS does provide various learning resources and training courses for customers, but it does not train the company's staff on the use of all the AWS services. AWS manages all security in the cloud is not a benefit that a company receives when it moves an on-premises production workload to AWS. AWS is responsible for the security of the cloud, but the customer is responsible for the security in the cloud. AWS offers free support from technical account managers (TAMs) is not a benefit that a company receives when it moves an on-premises production workload to AWS. AWS does offer support from TAMs, but only for customers who have the AWS Enterprise Support plan, which is not free.

• Question 943:

  Which AWS service or tool should a company use to forecast AWS spending?

  A. Amazon DevPay
  B. AWS Organizations
  C. AWS Trusted Advisor
  D. Cost Explorer
  D. Cost Explorer

  ---

  Explanation

  Cost Explorer is an AWS service or tool that can be used to forecast AWS spending. It allows users to analyze their AWS costs and usage using interactive graphs and tables. It also provides features such as filtering, grouping, and forecasting to help users plan their future spending. Amazon DevPay is an AWS service that allows developers to sell applications that are built on AWS services. It handles the billing and metering for the customers of the applications and collects payments from them. It is not a tool for forecasting AWS spending. AWS Organizations is an AWS service that allows users to centrally manage and govern their AWS accounts. It provides features such as creating groups of accounts, applying policies, and automating account creation. It is not a tool for forecasting AWS spending. AWS Trusted Advisor is an AWS service that provides best practices and recommendations to optimize the performance, security, and cost of AWS resources. It can help users identify opportunities to reduce their AWS costs, but it is not a tool for forecasting AWS spending

• Question 944:

  A company wants to build, train, and deploy machine learning (ML) models. Which AWS service can the company use to meet this requirement?

  A. Amazon Personalize
  B. Amazon Comprehend
  C. Amazon Forecast
  D. Amazon SageMaker
  D. Amazon SageMaker

  ---

  Explanation

  Amazon SageMaker is a fully managed service that provides developers and data scientists with the ability to build, train, and deploy machine learning (ML) models quickly. It offers integrated Jupyter notebooks for data exploration, pre-built

  algorithms, and automatic model tuning to optimize hyperparameters.

  Why other options are not suitable:

  Amazon Personalize: A managed machine learning service that provides personalized recommendations, but it does not offer the full suite of ML tools for building, training, and deploying models. Amazon Comprehend: A natural language

  processing (NLP) service, not a general-purpose ML model building and deployment service. Amazon Forecast: A managed service specifically for creating accurate forecasts using machine learning, not for general-purpose ML model

  development.

• Question 945:

• Question 946:

  A company needs to run a workload for several batch image rendering applications. It is acceptable for the workload to experience downtime.

  Which Amazon EC2 pricing model would be MOST cost-effective in this situation?

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

  ---

  Explanation

  Amazon EC2 Spot Instances are instances that use spare EC2 capacity that is available at up to a 90% discount compared to On-Demand prices. You can use Spot Instances for various stateless, fault-tolerant, or flexible applications such as big data, containerized workloads, high-performance computing (HPC), and test and development workloads. Spot Instances are ideal for workloads that can be interrupted, such as batch image rendering applications1. On-Demand Instances are instances that let you pay for compute capacity by the hour or second (minimum of 60 seconds) with no long-term commitments. This frees you from the costs and complexities of planning, purchasing, and maintaining hardware and transforms what are commonly large fixed costs into much smaller variable costs2. Reserved Instances are instances that provide you with a significant discount (up to 75%) compared to On-Demand Instance pricing. In exchange, you select a term and make an upfront payment to reserve a certain amount of compute capacity for that term3. Dedicated Instances are instances that run in a VPC on hardware that's dedicated to a single customer. Your Dedicated Instances are physically isolated at the host hardware level from instances that belong to other AWS accounts4.
