Which Feature Does Not Belong?

Answer: B.

The AWS Well architected framework is based on the five pillars - Security, Reliability, Performance efficiency, Cost Optimization & Operational Excellence.

Option A is incorrect since it belongs to the Security pillar of the AWS well architected framework.

Option B is CORRECT because configuring much more CPU resources than required is not appropriate in a cloud environment such as AWS.

This method is not cost-efficient as well.

Option C is incorrect since it belongs to the Cost Optimization pillar of the AWS well architected framework.

Option D is incorrect since it belongs to the Reliability pillar of the AWS well architected framework.

The Well-Architected Framework is a set of best practices and guidelines for designing and operating reliable, secure, efficient, and cost-effective systems in the AWS Cloud. It consists of five pillars: Operational Excellence, Security, Reliability, Performance Efficiency, and Cost Optimization.

Answer B does not belong to any of the pillars of the Well-Architected Framework in AWS.

Explanation of each answer:

A. Security: This pillar focuses on protecting information, systems, and assets. It includes strategies for confidentiality and integrity of data, identifying and managing risks, and implementing controls to detect and mitigate security threats.

B. Not a Well-Architected Framework pillar: The ability to configure servers with much more CPU resources than required so that users do not need to maintain the CPU resources for a long time is not a characteristic of any of the five pillars of the Well-Architected Framework.

C. Cost Optimization: This pillar focuses on avoiding or eliminating unneeded costs. It includes strategies for optimizing the use of resources, monitoring usage, and identifying opportunities for cost savings.

D. Reliability: This pillar focuses on the ability to recover from infrastructure or system failures. It includes strategies for designing fault-tolerant systems, implementing backup and recovery procedures, and testing and validating disaster recovery plans.

In summary, the correct answer is B, which is not a feature of any Well-Architected Framework pillar in AWS.
