- Explanation:
  - A (Correct): Kinesis Data Firehose is specifically designed to capture, transform, and load streaming data into S3, Redshift, or OpenSearch with minimal setup.
  - B (Incorrect): Snowball is for physical, large-scale data migration, not real-time streaming.
  - C (Incorrect): S3 Batch is for performing large-scale operations on existing objects in S3, not for real-time ingestion.
  - D (Incorrect): Storage Gateway connects on-premises storage to cloud storage but isn't a streaming transformation tool.
  - E (Incorrect): This is a database scaling feature, not an ingestion tool for data lakes.
  - F (Incorrect): This is a legacy tool mainly used for scheduled movement of data between AWS services, not optimized for low-latency streaming.
Question 2: Which AWS security feature should a data engineer implement to ensure that sensitive data within an Amazon Redshift cluster is only visible to authorized users based on specific database roles?
- A. S3 Bucket Policies
- B. Redshift Role-Based Access Control (RBAC)
- C. AWS WAF (Web Application Firewall)
- D. Amazon GuardDuty
- E. AWS Shield Standard
- F. VPC Security Groups
- Correct Answer: B
- Explanation:
  - B (Correct): RBAC allows for granular control over who can access specific tables or views within the Redshift cluster.
  - A (Incorrect): Bucket policies control access to the storage layer (S3), not the internal data rows of a Redshift database.
  - C (Incorrect): WAF protects web applications from common exploits, not internal database access.
  - D (Incorrect): GuardDuty is a threat detection service, not an access control mechanism.
  - E (Incorrect): Shield is for DDoS protection.
  - F (Incorrect): Security Groups control network-level traffic to the cluster but cannot manage user permissions inside the database.
Question 3: A team wants to catalog metadata from multiple data sources, including Amazon S3 and Amazon RDS, to make it searchable for analytics. Which service provides a central metadata repository?
- A. AWS Glue Data Catalog
- B. Amazon Route 53
- C. AWS Artifact
- D. Amazon CloudWatch Logs
- E. AWS Secrets Manager
