AWS Service for Cross-Region Resource Copies
Short answer
B AWS CloudFormation allows users to create copies of resources across AWS Regions by provisioning stacks defined in JSON or YAML templates.
Question
Key Takeaways
The question tests knowledge of infrastructure deployment tools versus logging or caching services; the common trap is confusing CloudFormation with CloudTrail, which only logs activity rather than creating resource copies.
This question tests the capability of AWS CloudFormation to provision identical infrastructure across multiple regions using templates. The correct answer is B, as it allows users to create copies of resources by defining stacks in different target Regions.
Common mistake: Learners often mistakenly select AWS CloudTrail (C) because they associate 'tracking' with 'copying', or they fail to recognize that CloudFormation's template-based approach is the primary mechanism for replicating infrastructure definitions across regions.
Expert Analysis
Why the Answer Is Correct
AWS CloudFormation enables users to create copies of resources across AWS Regions by using infrastructure-as-code templates. A single template can be used to provision a "stack" in multiple different Regions, effectively creating copies of the defined resources in each location. This aligns with objective 3.1 regarding methods of deploying and operating in the AWS Cloud.
Why the Other Options Are Wrong
Amazon ElastiCache (A) is an in-memory caching service and does not handle resource replication across regions for general infrastructure. AWS CloudTrail (C) is a logging service that records API calls; it does not create or copy compute/storage resources. AWS Systems Manager (D) is used for operational tasks like patching and configuration management, not for provisioning copies of infrastructure resources.
Community Comment Notes
The community consensus strongly favors option B, with comments noting that CloudFormation uses templates to define collections of resources known as stacks. One commenter highlighted that developers can write code once and use it multiple times, implying its utility for repeated provisioning. Another user simply confirmed that CloudFormation is the correct choice for this function.
Exam Strategy
When asked about creating copies of resources or provisioning infrastructure, look for Infrastructure as Code (IaC) services like CloudFormation or CDK. Distinguish these from monitoring/logging services like CloudTrail, which observe changes but do not create the resources themselves.

AravindrajG 👍 2AWS CloudFormation is an infrastructure as code (IaC) service that allows you to easily model, provision, and manage AWS and third-party resources. Developers can define and provision AWS infrastructure resources using a JSON- or YAML-formatted infrastructure as code template. Once Developer or Architect write the code to Infrastructure provision as a code (template),they can use multiple times without using GUI configuration It automatically creates Infrastructure by using the what in our template Answer is B.AWS CloudFormation
