CLF-C02 Cloud Technology & Services Cloud Technology & Services Practice Questions

Amazon CloudFront is a CDN that caches video content at edge locations around the world, delivering it to viewers from the nearest location and achieving high transfer speeds globally.

Amazon SNS is a pub/sub messaging service for sending notifications to multiple subscribers and has no role in delivering or streaming video content globally. Amazon Kinesis Video Streams ingests and processes live video streams from devices for real-time analysis and storage, but is not a content delivery service for distributing pre-recorded video to global audiences with high transfer speeds. AWS CloudFormation is an infrastructure-as-code service for provisioning AWS resources through templates, and has no capability to deliver or accelerate content to global users.

Amazon ECS is a fully managed container orchestration service that allows you to run and manage Docker containers on a cluster of EC2 instances or using AWS Fargate for serverless compute.

AWS Data Pipeline (deprecated) is a service for orchestrating and automating the movement and transformation of data between AWS services, not for running containerised applications. AWS Cloud9 is a cloud-based integrated development environment for writing and debugging code, unrelated to container orchestration. AWS Health Dashboard provides alerts and guidance when AWS service events may affect your resources, not a compute or container service.

AWS X-Ray provides distributed tracing for microservices applications, allowing developers to visualise the end-to-end path of requests, identify bottlenecks, and diagnose the root cause of performance and latency issues.

AWS CodePipeline automates the steps of a continuous delivery pipeline for releasing application code, including building, testing, and deploying, and is a CI/CD automation tool with no capability to trace requests or diagnose runtime performance issues. Amazon Inspector is an automated security assessment service that scans EC2 instances and container images for software vulnerabilities and unintended network exposure, and is a security tool rather than a performance troubleshooting service. AWS CloudTrail records API calls and account activity across an AWS environment for auditing and compliance purposes, and does not trace application requests or provide visibility into latency and performance bottlenecks within microservices.

AWS Health Dashboard provides real-time status information about all AWS services across all AWS Regions, allowing anyone to check the current operational health of the AWS infrastructure.

AWS Service Catalog allows organizations to create and manage approved catalogs of IT services for internal use and self-service provisioning, and has no connection to displaying the current status of AWS services globally. AWS Management Console is the web-based interface for accessing and managing AWS services, and while it provides access to many dashboards it is not itself the service that publishes current status information about AWS infrastructure health. Amazon CloudWatch collects metrics, logs, and event data from your own AWS resources and applications to provide operational monitoring and alerting, and is a customer-facing monitoring tool rather than a service that publishes the health status of AWS infrastructure itself.

AWS Application Discovery Service collects information about on-premises servers, including configuration, usage, and dependencies, to help plan and prioritize migration to the AWS Cloud.

AWS Snowball is a physical device used to transfer large volumes of data into AWS and is a data transfer tool rather than a migration planning service. AWS Database Migration Service migrates databases to AWS with minimal downtime, but handles the execution of database migrations rather than the discovery and planning phase. AWS Migration Hub provides a central location to track the progress of migrations across multiple AWS and partner tools, but it monitors migration status rather than collecting the server data needed to plan a migration.
