question 23: A company currently stores all of its data in Amazon S3 by using the S3 Standard storage class. A data engineer examined data access patterns to identify trends. During the first 6 months, most data files are accessed several times each day. Between 6 months and 2 years, most data files are accessed once or twice each month. After 2 years, data files are accessed only once or twice each year. The data engineer needs to use an S3 Lifecycle policy to develop new data storage rules. The new storage solution must continue to provide high availability. Which solution will meet these requirements in the MOST cost-effective way? Options: A. Transition objects to S3 One Zone-Infrequent Access (S3 One Zone-IA) after 6 months. Transfer objects to S3 Glacier Flexible Retrieval after 2 years. B. Transition objects to S3 Standard-Infrequent Access (S3 Standard-IA) after 6 months. Transfer objects to S3 Glacier Flexible Retrieval after 2 years. C. Transition objects to S3 Standard-Infrequent Access (S3 Standard-IA) after 6 months. Transfer objects to S3 Glacier Deep Archive after 2 years. D. Transition objects to S3 One Zone-Infrequent Access (S3 One Zone-IA) after 6 months. Transfer objects to S3 Glacier Deep Archive after 2 years. The question clearly mentioned "The new storage solution must continue to provide high availability. ", so C is the wrong answer, Glacier Deep Archive offers retrieval options of 12-48 hours, while Flexible Retrieval offers expedited retrievals in 1-5 minutes. As 'high availability is the concern', I would rather go with Option B which is Glacier Flexible Retrieval
Question 22: A company maintains multiple extract, transform, and load (ETL) workflows that ingest data from the company’s operational databases into an Amazon S3-based data lake. The ETL workflows use AWS Glue and Amazon EMR to process data. The company wants to improve the existing architecture to provide automated orchestration and to require minimal manual effort. Which solution will meet these requirements with the LEAST operational overhead? Options: A. AWS Glue workflows B. AWS Step Functions tasks C. AWS Lambda functions D. Amazon Managed Workflows for Apache Airflow (Amazon MWAA) workflows This should be B, cause glue workflows are tightly coupled with glue ecosystem, the question says integrating EMR, this should be done by step function cause mwaa also needs additional infra.
I took my exam today, I can confirm that all the questions came out word for word. I answered everything within 50 minutes. But I am yet to see my result. How long does it take to see the result?
Congratulations on completing your exam! 🎉 If it's an AWS certification exam, the results are usually available immediately after you finish. You should see a preliminary pass or fail message on the testing screen, and the detailed results (score breakdown) are typically emailed to you within a few hours. If you don't see your results yet, check your AWS Certification Dashboard as the scores are often posted there within 24 hours. Let me know if you need help with anything else, and good luck with your results! 😊🙌
thanks for all you do, I just have one question, are we going to get a machine learning associate exam anytime soon?
I just saw my score. I got 856🎉🎉. Many thanks to our instructor for .making this possible.

For Q27 as per the tutorials, it is option D. But in the solutions sheet it is marked as C. Please confirm which one is correct?

Q.112- Answer sheet is giving wrong answer. It is B, while answer sheet selects 2 options- which is not even asked.
Correct answer should be A.
Sorry about that, The answer is A, looks like copy paste issue while preparing the answer key.

@@bhavyashah98 yes.
I answered some questions without reading the questions.
Watch all. Most importantly, make sure you understand the concept. It's very important.
