Read the first 7 Solutions Architect Cloud Architecture & Design flashcards as text

  1. A company needs to migrate a 50 TB on-premises Oracle database to AWS with minimal downtime. Which combination of services best supports this?

    Answer: AWS Snowball Edge + AWS Database Migration Service (DMS)

    Snowball Edge transfers the bulk data offline, and DMS handles ongoing change data capture replication to minimize cutover downtime.

  2. Which AWS Well-Architected pillar focuses on avoiding unnecessary costs and ensuring systems deliver business value at the lowest price point?

    Answer: Cost Optimization

    The Cost Optimization pillar covers understanding and controlling where money is being spent, selecting the right pricing model, and eliminating waste.

  3. An architect needs to deliver static assets globally with the lowest possible latency and must protect against DDoS attacks at no extra cost. Which solution is best?

    Answer: Amazon CloudFront with AWS Shield Standard

    CloudFront caches content at edge locations worldwide, and AWS Shield Standard is automatically included with CloudFront at no additional cost, mitigating common DDoS attacks.

  4. A Lambda function must securely retrieve a database password that is automatically rotated every 30 days. What is the recommended approach?

    Answer: Retrieve the password at runtime from AWS Secrets Manager

    AWS Secrets Manager supports automatic rotation and provides a managed API for retrieving secrets at runtime, making it the best fit for rotating database credentials.

  5. A company has a legacy application that can only scale vertically. Which EC2 feature allows changing the instance type with the least disruption?

    Answer: EC2 instance type change via Stop-Modify-Start

    Stopping an EC2 instance, modifying its instance type in the console or CLI, and restarting it is the direct way to vertically scale a single instance.

  6. Which Amazon S3 storage class is most cost-effective for data that is accessed infrequently but must be retrieved within milliseconds when needed?

    Answer: S3 Standard-Infrequent Access (S3 Standard-IA)

    S3 Standard-IA offers lower storage costs than S3 Standard with millisecond retrieval, designed for data accessed less than once a month.

  7. An application uses an Application Load Balancer (ALB) and needs to route requests to different target groups based on the URL path. Which ALB feature enables this?

    Answer: Path-based routing rules

    ALB path-based routing rules allow you to forward requests matching specific URL path patterns (e.g., /api/* vs /images/*) to different target groups.
