AWS Well-Architected Framework and Design Principles Flashcards

A team holds 'pre-mortem' exercises to find potential failure sources before launch. Which Operational Excellence design principle is this?

Answer: Anticipate failure

Pre-mortems find likely failures so they can be removed or mitigated ahead of time.

After every incident, a company runs a blameless post-incident analysis and shares the lessons across teams. Which Operational Excellence principle is this?

Answer: Learn from all operational failures

Sharing lessons from operational events and failures drives improvement across the organization.

Running incident response simulations and using automation to speed up detection and investigation supports which Security design principle?

Answer: Prepare for security events

Preparing for incidents with matching processes, simulations, and tools speeds up response and recovery.

Using centralized identity management, enforcing least privilege, and eliminating long-term static credentials supports which Security design principle?

Answer: Implement a strong identity foundation

A strong identity foundation centralizes privilege management and enforces least privilege with separation of duties.

Why does choosing managed services like AWS Fargate support the Sustainability pillar?

Answer: Shared infrastructure across many customers maximizes resource utilization

Managed services spread infrastructure across many customers, which raises utilization and lowers the resources needed.

Choosing a database based on the workload's actual data access patterns rather than team familiarity reflects which Performance Efficiency principle?

Answer: Consider mechanical sympathy

Mechanical sympathy means understanding how cloud services are consumed and picking the technology that fits your workload goals.

In the AWS Well-Architected Tool, what is a 'milestone'?

Answer: A record of a workload's state at a particular point in time

Milestones save a snapshot of a workload review so you can track improvement over time.
