AWS GLUE JOB KNOWLEDGE EXAM
2025/2026 QUESTIONS AND ANSWERS
100% PASS
What is AWS Glue? - ANS A serverless data integration service
What is AWS Glue crawler? - ANS - A data discovery tool used to search datastore
- Scans and analyzes data.
- Infers data schema and creates tables in the AWS Glue Data Catalog, making it queryable
What is the purpose of AWS Glue's Data Catalog? - ANS A metadata repository for all your
data across various data sources. It allows you to store and query data (almost like MySQL)
What is the process of AWS Glue Data Discovery? - ANS When AWS Glue Crawler connects to
your datastore (like s3 or DynamoDB) infers the schema and create a table in glue catalog by
writing metadata
What does ETL mean? - ANS - Extract: Data from Data Source (like raw S3 or DynamoDB)
1 @COPYRIGHT 2025/2026 ALLRIGHTS RESERVED.
,- Transform: Using your Glue Script (Like CSV to Parquet)
- Load: to data target (like trusted S3 or DynamoDB)
What is extraction of data? - ANS The process of retrieving data so it can be processed,
transformed, and loaded into another data store
What is the transformation of data? - ANS The process of writing a Glue job script for like
cleansing, re-formatting, aggregating, mapping, and more on the extracted data. The objective
is to prepare and optimize the data which can be easily consumed
What is loading data? - ANS The process of inserting the transformed data into the target
database, data warehouse, data store from where the users and various processes can consume
it
What is it called when the extraction, transformation, and load processes work together? -
ANS An ETL job
Benefits of using AWS and Terraform for cloud data? - ANS -AWS: Using Amazon Web
Services (AWS) for cloud data offers benefits like scalability, reliability, and a wide range of cloud
services and tools. AWS provides managed data storage, processing, and analytics services,
making it easier to build and manage data solutions at scale.
-Terraform: Terraform is an Infrastructure as Code (IaC) tool that offers benefits such as
automation, version control, and consistency. When used in conjunction with AWS, Terraform
allows you to define and provision cloud data resources and configurations in a structured and
repeatable manner.
Together, AWS and Terraform streamline cloud data management by providing cloud
infrastructure and automation capabilities.term-37

, What is the Glue Console? - ANS The Glue Console is a interface that allows you to interact
with and manage various aspects of AWS Glue, such as creating and managing ETL jobs, defining
data catalogs, setting up crawlers, and monitoring and orchestrating data workflows. The Glue
Console is a visual tool for simplifying data preparation and transformation tasks in AWS.
Why is AWS Glue a serverless ETL? - ANS AWS Glue is a fully managed serverless
environment where you can extract, transform, and load (ETL) data at scale. With AWS Glue,
you can categorize data, clean it, enrich it, and move it reliably across various data stores and
streams in a cost-effective manner.
AWS Glue is serverless, so you don't have to worry about provisioning or managing servers.
With AWS Glue, you pay only for the resources you use, and you can scale up or down as
needed.
What is the difference between and purpose of raw and trust s3 buckets? - ANS -Raw S3
Bucket: stores unprocessed or minimally processed data.
-Trust S3 Bucket: stores data that has been processed, refined, and trusted for specific use
cases. It's often used to store clean, structured, and reliable data, making it suitable for direct
consumption by applications or analytics.
What is terraform? - ANS - An Infrastructure as Code (IaC) tool for provisioning and managing
infrastructure.
- Provides a way to create, modify, and version infrastructure as if it were software.
- Supports multiple cloud providers (like AWS), making it a versatile choice for infrastructure
automation.
