Interview Questions

Q1: What is the first stage in the data lifecycle management in AWS?

A1: The first stage in the data lifecycle management in AWS is Data Collection. It is the process of obtaining raw data in a structured and usable format.

Q2: What is Data Storage within the data lifecycle management of the AWS?

A2: Data Storage is the second stage of the lifecycle. After the data collection, it’s stored in AWS. Services like Amazon S3, Amazon EBS, or Amazon RDS can be utilized.

Q3: How is data processed in the AWS Data lifecycle?

A3: The data processing phase involves organizing, manipulating, and making sense of data to reach conclusions. Services like Amazon EMR, AWS Glue, or AWS Lambda can be used.

Q4: What is the purpose of the Analysis phase in data life cycle management?

A4: The Analysis phase helps stakeholders understand more about the business value of data, using tools such as Amazon QuickSight and AWS Athena.

Q5: What is the role of Data Archiving in AWS data lifecycle management?

A5: Data Archival is the fourth stage of the data lifecycle where data gets stored long-term in a secure and cost-effective manner using AWS Glacier or S3 storage classes.

Q6: What is the final stage of the AWS data lifecycle?

A6: The data destruction or purging is the final phase. AWS has support for both automated and manual data purging processes.

Q7: Name one AWS service that can be used to automate data lifecycle policies?

A7: You can use Amazon S3’s Lifecycle policies feature to automate tasks related to data expiry and deletion.

Q8: Can you store data indefinitely in AWS?

A8: Yes, using services like Amazon S3 or AWS Glacier, data can be stored indefinitely as long as your account remains active and in good standing.

Q9: How does versioning aid in AWS S3?

A9: S3 Versioning allows for storing multiple versions of an object and protecting from accidental overwrite or deletion.

Q10: How does AWS KMS service contribute to data lifecycle management?

A10: AWS KMS is used for creating and controlling the encryption keys that decrypt your data, thus giving you an additional layer of data security.

Q11: What AWS service could be used to set up business rules for managing data throughout its lifecycle?

A11: AWS DMS (Data Migration Service) can be used to manage business rules during the data migration phase, controlling how data is handled and stored.

Q12: What are Amazon S3 Lifecycle Policies used for?

A12: Amazon S3 Lifecycle Policies provide automated features to control the lifecycle of objects in your S3 buckets. They can define actions such as transitioning objects to lower-cost storage classes, archiving them, or deleting them after a defined period.

Q13: What is the purpose of the AWS Glue service?

A13: AWS Glue service is used for preparing and loading your data for analysis. It can extract, transform, and load (ETL) your data to your data store.

Q14: Can AWS DMS migrate data across different database engines?

A14: Yes, AWS Data Migration Service (DMS) supports homogeneous migrations such as Oracle to Oracle, as well as heterogeneous migration between different kinds of database engines such as Oracle to Amazon Aurora.

Q15: How does AWS Athena contribute to the Analysis phase of the data life cycle?

A15: AWS Athena allows users to perform ad-hoc analysis on data using standard SQL without the need for complex ETL jobs or data pipelines. This aids in gaining insights and making data-driven decisions.
