The AWS Certified Data Engineer – Associate (DEA-C01) exam validates your skills in data engineering on AWS. It is suitable for those who want to demonstrate their ability to design and implement data solutions.
Which service can help manage access permissions across multiple AWS accounts?
AAWS Organizations
BIAM Roles
CAWS Config
DCloudTrail
Explanation
AWS Organizations allows for centralized management of multiple accounts and their policies, whereas the others do not focus on account access management.
Q202
Which AWS service is ideal for long-term storage of data to reduce costs?
AAmazon S3 Glacier
BAmazon EC2
CAWS Lambda
DAmazon RDS
Explanation
S3 Glacier is specifically designed for long-term storage, while EC2 and RDS focus on compute and database management, respectively.
Q203
A company needs to process streaming data in real-time from multiple sources. Which service should they use?
AAWS Glue
BAmazon Kinesis
CAWS Batch
DSQS
Explanation
Amazon Kinesis is purpose-built for processing real-time streaming data, unlike Glue, Batch, and SQS which serve different functions.
Q204
You are configuring AWS IAM and need to enable users to access an S3 bucket without allowing them to delete objects. How would you achieve this?
AAttach a policy allowing 's3:DeleteObject' action
BGrant 's3:GetObject' and 's3:PutObject' actions
CUse a bucket policy to deny delete
DCreate a role without S3 permissions
Explanation
A bucket policy can specifically deny delete permissions while allowing others, whereas options A, B, or D are inadequate for the requirement.
Q205
Which service allows you to manage and provision AWS resources using code?
AAWS CloudFormation
BAWS Lambda
CAWS Systems Manager
DAWS CodeDeploy
Explanation
AWS CloudFormation provides infrastructure as code capabilities to manage AWS resources, while other options relate to deployments or system management.
Q206
You are configuring a Data Pipeline that pulls data from Amazon S3 and processes it in an EC2 instance. What is the ideal role for the EC2 instance to access S3 data?
AS3 Full Access Role
BData Pipeline Access Role
CEC2 Instance Role
DAWS Lambda Role
Explanation
Assigning an EC2 instance role enables desired permissions for S3 access, while other roles do not directly apply to an EC2 instance.
Q207
What happens when you delete an Amazon RDS instance?
AData is lost permanently
BData is stored in S3
CInstance configuration is retained
DIt is archived for a month
Explanation
Deleting an Amazon RDS instance permanently removes data unless a snapshot is taken prior, while other options misrepresent the deletion process.
Q208
Which service is ideal for real-time data stream processing?
AAmazon Kinesis
BAmazon S3
CAmazon RDS
DAmazon DynamoDB
Explanation
Amazon Kinesis is specifically designed for processing real-time data streams; S3 is for static storage, RDS is a relational database, and DynamoDB is a NoSQL database.
Q209
A company needs to deploy a temporary IAM role for developers to complete a project. What features should the role include?
AMulti-Factor Authentication
BTemporary Security Credentials
CPermanent Security Access
DS3 Bucket Policy
Explanation
Temporary security credentials are required for limited-time access; MFA enhances security but isn’t essential, permanent access is not temporary, and S3 bucket policies relate to storage.
Q210
What happens when an EBS volume is detached from an instance?
AData is lost permanently
BData remains intact until deleted
CVolume auto-deletes immediately
DInstance crashes due to loss
Explanation
Detached EBS volumes retain their data until manually deleted; data loss isn’t automatic, volumes don’t delete themselves, and instance stability isn’t necessarily affected.
