• Question 1074:

  A company wants to estimate and compare the cost of running its existing on-premises infrastructure on AWS before migrating to the AWS Cloud.

  Which AWS service will meet this requirement?

  A. AWS Cost Explorer
  B. AWS Budgets
  C. AWS Pricing Calculator
  D. AWS Trusted Advisor
  C. AWS Pricing Calculator

  ---

  Explanation

  According to AWS official documentation, the AWS Pricing Calculator is designed to estimate and compare the cost of running workloads on AWS versus on-premises environments. This service allows customers to model their existing infrastructure, including compute, storage, and data transfer requirements, and then estimate AWS costs before migrating. AWS Pricing Calculator supports detailed cost breakdowns for individual services and helps organizations make informed financial decisions during cloud adoption planning.

  AWS Cost Explorer and AWS Budgets are used only after workloads are already running on AWS to analyze and manage existing AWS costs. AWS Trusted Advisor provides best-practice recommendations related to cost optimization, security, fault tolerance, and performance, but it does not perform cost comparisons with on-premises environments.

  AWS documentation explicitly states that the AWS Pricing Calculator is intended for pre-migration cost estimation and comparison, making it the correct service for evaluating on-premises versus AWS cost scenarios.

• Question 1076:

  A company provides a software as a service (SaaS) application. The company has a new customer that is based in a different country.

  The new customer's data needs to be hosted in that country.

  Which AWS service or infrastructure component should the company use to meet this requirement?

  A. AWS Shield
  B. Amazon S3 Object Lock
  C. AWS Regions
  D. Placement groups
  C. AWS Regions

  ---

  Explanation

  AWS Regions are geographic areas around the world where AWS has clusters of data centers. Each AWS Region consists of multiple, isolated, and physically separate AZ's within a geographic area. By hosting the customer's data in a specific AWS Region, the company can meet the requirement of hosting the data in the customer's country. AWS Shield is a service that provides always-on detection and automatic inline mitigations that minimize application downtime and latency, so there is no need to engage AWS Support to benefit from DDoS protection. Amazon S3 Object Lock is a feature that allows you to store objects using a write-once-read-many (WORM) model. You can use it to prevent an object from being deleted or overwritten for a fixed amount of time or indefinitely. Placement groups are logical grouping of instances within a single Availability Zone. Placement groups enable applications to participate in a low-latency, 10 Gbps network. None of these services or infrastructure components can help the company host the customer's data in a different country.
