AWS Trusted Advisor

Trusted Advisor inspects the AWS environment to make recommendations for system performance, saving money, availability, and closing security gaps
Trusted Advisor checks the following categories
- Cost Optimization
  - Recommendations that can potentially save money by highlighting unused resources and opportunities to reduce your bill.
- Security
  - Identification of security settings and gaps, inline with the best practices, that could make the AWS solution less secure
- Fault Tolerance
  - Recommendations that help increase the resiliency and availability of the AWS solution by highlighting redundancy shortfalls, current service limits, and over-utilized resources.
- Performance
  - Recommendations that can help to improve the speed and responsiveness of the applications
- Service Limits (Circa Nov 2017 – Latest Addition)
  - Checks for service usage that is more than 80% of the service limit.
  - Values are based on a snapshot, so the current usage might differ.
  - Limit and usage data can take up to 24 hours to reflect any changes

AWS Certification Exam Practice Questions

Questions are collected from Internet and the answers are marked as per my knowledge and understanding (which might differ with yours).

AWS services are updated everyday and both the answers and questions might be outdated soon, so research accordingly.

AWS exam questions are not updated to keep up the pace with AWS updates, so even if the underlying feature has changed the question might not be updated

Open to further feedback, discussion and correction.
