    Study Notes

    Information System Architecture Quiz - Study Notes

    • Question 1: Unpredictable storage demand (fluctuating throughout the year) benefits most from moving a local data store to AWS. Constant, stable demand does not.

    • Question 2: The request-response integration pattern is commonly used in web APIs when immediate data retrieval is needed.

    • Question 3: A Dockerfile contains instructions to create an image. The docker run command executes a container.

    • Question 4: A cloud service is not specific to each client. It relies on pay-per-use billing, on-demand access, and allows for flexibility.

    • Question 5: AWS Simple Storage Service (S3) is an example of an AWS storage solution.

    • Question 6: Cloud benefits include cost efficiency, innovation opportunities, and improved agility/development speed (faster time-to-market).

    • Question 7: Important considerations for IS urbanization (integrating systems) include centralizing user authentication, identifying external data exchanges, and grouping business logic within isolated blocks.

    • Question 8: Prerequisites for event sourcing include saving all produced events in a database and producing an event for each application state modification.

    • Question 9: PaaS (Platform as a Service) is suitable for teams focused only on application logic.

    • Question 10: For minimizing costs when migrating database backups, use an S3 bucket (Simple Storage Service) on AWS.

    • Question 11: Scaling out adds more machines; scaling up adds more power (CPU, RAM) to a single machine.

    • Question 12: Based on the provided Dockerfile:

      • Internet connection is frequently needed to build a Dockerfile.
      • The image will have NodeJS 10 installed after building.
      • Executing "ls" in the running container displays files in the /app/ directory (assuming a copy). -All files in the Dockerfile directory are copied to the image.

    • Question 13: Maintain data consistency in CQRS (Command Query Responsibility Segregation) architecture by updating read databases with commands, using daily ETL processes, and generating modification events.

    • Question 14: Publish/subscribe (PubSub) is used when numerous applications need the same event information.

    • Question 15: Vertical scaling (scale-up) involves increasing resources (memory) on a single virtual machine, not increasing the number of containers or machines.

    • Question 16: Caching is temporary data storage; permanent storage is not a cache.

    • Question 17: Communication in a microservices architecture commonly uses asynchronous message buses and/or web services.

    • Question 18: Steps for cloud migration: Rehost, Replatform, Refactor, Rebuild.

    • Question 19:

      • Figure A represents batch data processing.
      • Figure B represents event-driven architecture or applications that are publishing or subscribing to events.
      • Figure C represents a web-service API type of architecture

    • Question 20:

      • OAuth2 access tokens allow user authentication and express roles.
      • Token integrity is verified via signatures.
      • Access tokens are represented as JSON Web Tokens (JWT).

    • Question 21: Docker containers require an operating system and a Docker runtime.

    • Question 22: PaaS (Platform as a Service) is a service that orchestrates, manages, and deploys containers on virtual machines.
