Read the first 7 AWS Well-Architected Framework and Design Principles flashcards as text

  1. Which of the following is NOT one of the six pillars of the AWS Well-Architected Framework?

    Answer: Scalability

    The six pillars are Operational Excellence, Security, Reliability, Performance Efficiency, Cost Optimization, and Sustainability; scalability is a quality, not a pillar.

  2. A team replaces one large EC2 instance with several smaller instances behind an Application Load Balancer. Which Reliability design principle does this follow?

    Answer: Scale horizontally to increase aggregate workload availability

    Spreading requests across multiple smaller resources reduces the impact of any single failure.

  3. A company uses AWS WAF, security groups, network ACLs, and OS hardening together. Which Security design principle is being applied?

    Answer: Apply security at all layers

    Defense in depth applies controls at every layer, including the edge, VPC, subnet, instance, OS, and application.

  4. Which Operational Excellence design principle recommends deploying updates in small increments that can be easily rolled back?

    Answer: Make frequent, small, reversible changes

    Small, reversible changes reduce the blast radius of failures and make it easier to roll them back.

  5. A startup deploys its application to multiple AWS Regions with a few clicks to lower latency for global users. Which Performance Efficiency design principle is this?

    Answer: Go global in minutes

    Deploying to multiple Regions quickly gives users lower latency at minimal cost.

  6. Migrating a self-managed MySQL database on EC2 to Amazon RDS best aligns with which Cost Optimization design principle?

    Answer: Stop spending money on undifferentiated heavy lifting

    Managed services take over operational tasks like patching and backups so teams can focus on business value.

  7. What is the cost of using the AWS Well-Architected Tool in the AWS Management Console?

    Answer: It is free; you pay only for the underlying AWS resources you use

    The AWS Well-Architected Tool costs nothing to use for reviewing workloads.
