AWS Storage and Data Management Flashcards
AWS Certified Data Engineer Associate DEA-C01 Flashcards
| Front | Back |
| How can you optimize Redshift performance | Use distribution keys, sort keys, and compression. |
| How does Amazon Glacier differ from S3 | Designed for long-term, low-cost archival storage with retrieval delays. |
| How does Amazon Redshift handle complex queries | Parallel processing and columnar storage for high-speed analysis. |
| How does Amazon S3 Transfer Acceleration work | Speeds up cross-region uploads using AWS edge locations. |
| How does DynamoDB achieve scalability | Uses partitioning and auto-scaling to handle large workloads seamlessly. |
| How does DynamoDB Streams help in real-time data processing | Captures table-level changes for downstream applications. |
| How does S3 Versioning help | Tracks changes to objects and maintains previous versions for recovery. |
| What are Reserved Instances in RDS | Discounted pricing for long-term RDS usage commitment. |
| What are S3 storage classes | Tiers designed for different access patterns, including Standard, Intelligent-Tiering, and Glacier. |
| What are the different backup options in RDS | Supports automated snapshots and manual backups. |
| What does the SELECT statement in S3 Query do | Allows querying of S3 objects using SQL-like syntax. |
| What is Amazon Aurora | High-performance relational database compatible with MySQL and PostgreSQL. |
| What is Amazon DynamoDB | NoSQL database for low-latency applications with support for key-value and document data models. |
| What is Amazon Redshift | Cloud-based data warehouse optimized for large-scale analytical queries. |
| What is Amazon S3 | Scalable object storage for storing and retrieving any amount of data. |
| What is AWS DataSync | Service for seamless movement of data between on-premises storage and AWS. |
| What is Elastic Block Store (EBS) | Block storage for use with EC2 instances, optimized for performance and reliability. |
| What is Lifecycle Management in Amazon S3 | Automates transition and expiration of objects based on rules. |
| What is the difference between RDS Multi-AZ and Read Replicas | Multi-AZ provides failover, while Read Replicas improve read scalability. |
| What is the purpose of S3 Multipart Upload | Improves upload efficiency for large objects by breaking them into parts. |
| What is the Query function in DynamoDB | Retrieves items based on primary key attributes. |
| What purpose does S3 Object Lock serve | Enforces data immutability for compliance or business needs. |
| What type of storage does Amazon RDS use | Managed relational database services using SSD-backed EBS volumes. |
| When should you use an S3 bucket policy | To define access permissions for the entire bucket. |
This deck covers Amazon S3, DynamoDB, Redshift, RDS, and other storage options along with best practices for managing and retrieving data efficiently.
