[All CLF-C02 Questions]

Which design principles support the reliability pillar of the AWS Well-Architected Framework? (Select TWO.)

APerform operations as code.

BEnable traceability.

CAutomatically scale to meet demand.

DDeploy resources globally to improve response time.

EAutomatically recover from failure.

Show Suggested Answer

Suggested Answer: C, E

The design principles that support the reliability pillar of the AWS Well-Architected Framework are: automatically scale to meet demand, and automatically recover from failure. These principles help users design systems that can handle changes in load, avoid disruptions, and resume normal operations quickly. Automatically scaling to meet demand means adjusting the capacity of the system based on the current and anticipated workload, using services such as AWS Auto Scaling, Amazon EC2, and AWS Lambda.Automatically recovering from failure means detecting and resolving issues, using services such as Amazon CloudWatch, AWS CloudFormation, and AWS CloudTrail

I’m leaning towards "Automatically scale to meet demand" as one of the answers, but I can't recall if it directly ties to reliability in the same way as recovery does.

I feel like "Perform operations as code" could relate to reliability, but I’m not entirely confident if it’s the best choice here.

I remember practicing a question similar to this, and I think "Enable traceability" was mentioned as important for reliability too.

Traceability is important for reliability, but I'm not sure if that's the best answer here. I'll need to think through the options and make sure I select the two that are most directly related to the reliability pillar.

Automatically scaling to meet demand and deploying resources globally could also support reliability, but I'm not 100% sure. I'll need to double-check my understanding of the reliability pillar.

Hmm, I'm a bit unsure about this one. The options seem to cover a range of different AWS concepts, so I'll need to carefully consider which ones are specifically related to reliability.

This looks like a straightforward question about the AWS Well-Architected Framework. I'll focus on the "reliability" pillar and think about which design principles support that.
