A domain in Amazon CloudSearch acts as a centralized hub for all search activities and data. When you create a domain, CloudSearch provisions the required resources and deploys the search index for your domain. Each domain has its unique URL that you use to submit data for indexing and perform sear…

Question 1

A company needs to migrate its on-premises production databases to AWS while keeping application downtime to an absolute minimum. Which AWS service should they use to perform the migration?

Correct Answer: AWS Database Migration Service

AWS Database Migration Service (AWS DMS) is designed to migrate databases to AWS with minimal downtime. It uses continuous data replication via change data capture (CDC) so the source database remains operational during migration, enabling a short cutover window. AWS Data Pipeline orchestrates data movement and transformation but does not provide live, low-downtime database migration. AWS Elastic Beanstalk is a deployment service for applications, not a database migration tool. AWS Batch is for running batch computing workloads and is unrelated to migration.

Question 2

A media company runs long-running video transcoding jobs on custom AMIs using specialized EC2 instance types (including GPU-optimized instances). The workloads process very large files, are not containerized, and the team cannot re-architect to containers or serverless. Demand is highly variable with traffic spikes, and they want a cost-effective solution that automatically scales capacity out and in based on demand (e.g., queue depth). What should you recommend?

Correct Answer: AWS EC2 Auto Scaling

AWS EC2 Auto Scaling is the best fit for long-running, non-containerized video processing jobs that may need specialized EC2 instance types (such as GPU-optimized instances) and custom AMIs. It can automatically add and remove instances based on demand signals (for example, queue depth or CPU utilization) and supports cost-optimization strategies like mixing On-Demand and Spot Instances. AWS Lambda is unsuitable because of its maximum execution duration and resource limits for large video processing. Amazon ECS requires containerization, which is explicitly not an option here. Reserved EC2 Instances commit capacity and are not ideal for rapidly fluctuating workloads that need elastic scale-out and scale-in.

Question 3

A client wants to create a web application that requires high availability and fault tolerance. They need a secure environment to store user data in multiple AWS regions. Which storage service would best meet their requirements?

Correct Answer: Amazon S3

Amazon S3 is designed for high durability and availability, and it supports cross-region replication for securing data in multiple regions. The other storage services are either unsuitable for cross-region replication or do not meet the high availability and fault tolerance requirements.
