CorrectA, C
Explanation
A question asking which two service-to-role pairings are correct.
- 1「service to its role」Correctly map the roles of WorkSpaces, IoT Core, OpenSearch, Amplify, and EMR
BIncorrect
Amazon AppStream 2.0 — Provides a complete cloud-hosted virtual desktop environment.
Amazon AppStream 2.0 is a service that streams individual applications to end users.
Providing a complete desktop environment is the role of Amazon WorkSpaces; this option swaps the descriptions of the two services, so this is incorrect.
CCorrect
Amazon OpenSearch Service — Provides search, analysis, and visualization of logs and data.
This is correct. Amazon OpenSearch Service is a managed service that performs full-text search, analysis, and dashboard-based visualization of logs and data.
DIncorrect
AWS Amplify — An IaC service that defines and provisions the entire infrastructure using templates.
AWS Amplify is a development platform for rapidly building and hosting web and mobile application front ends and back ends.
The key distinction is the starting point: IaC (CloudFormation) is a general-purpose mechanism for assembling any infrastructure exactly as defined in a template; Amplify is an app-development-focused platform that automatically provisions the components an app needs (authentication, API, hosting). Although Amplify provisions resources behind the scenes, describing it as a service that defines and provisions the entire infrastructure using templates is incorrect.
EIncorrect
Amazon EMR — Ingests and delivers real-time streaming data.
Amazon EMR is a service that processes large-scale data using frameworks such as Spark and Hadoop, primarily handling batch analytical processing.
Real-time ingestion and delivery of streaming data is the role of Kinesis; this option pairs the wrong service with the description, so this is incorrect.
Key Takeaway
Mappings: WorkSpaces = full virtual desktop / AppStream = streaming individual applications / OpenSearch = search, analytics, and visualization / Amplify = web and mobile app development / EMR = big data processing. Learn to identify the representative service in each category.
