Read the first 7 Cloud Computing & Infrastructure flashcards as text

  1. What distinguishes a stateless application from a stateful one in cloud architecture?

    Answer: Stateless apps do not retain client session data between requests

    Stateless applications treat each request independently without storing session data locally, making them easy to scale horizontally.

  2. Which AWS service provides a fully managed message queue for decoupling microservices?

    Answer: Amazon SQS

    Amazon SQS (Simple Queue Service) is a fully managed message queuing service that enables decoupled, asynchronous communication between components.

  3. What is the purpose of a subnet mask in cloud virtual network configuration?

    Answer: To define which portion of an IP address identifies the network vs. the host

    A subnet mask divides an IP address into the network prefix and host identifier, determining the size and range of the subnet.

  4. Which cloud concept describes running identical infrastructure across multiple regions to serve traffic to the nearest users?

    Answer: Multi-region active-active deployment

    An active-active multi-region deployment runs live workloads simultaneously in multiple geographic regions, routing users to the closest healthy region.

  5. What does the term 'lift and shift' mean in the context of cloud migration?

    Answer: Moving applications to the cloud with minimal or no code changes

    Lift and shift (rehosting) moves applications to cloud VMs as-is, without re-architecting them to leverage cloud-native capabilities.

  6. In cloud IAM, what is the principle of least privilege?

    Answer: Giving users and services only the minimum permissions needed for their tasks

    The principle of least privilege limits access rights to the bare minimum required for a user or service to perform its intended function.

  7. Which cloud monitoring metric would best indicate that a web server is approaching CPU exhaustion?

    Answer: CPU utilization percentage

    CPU utilization percentage directly measures how much processing capacity is being consumed, signaling potential throttling or slowdowns when near 100%.
