Exam Topics Covered:

The exam assesses your knowledge across four key sections:

1. Designing Data Processing Systems:

• Storage Technologies: Selecting appropriate storage solutions based on business needs, data modeling, latency/throughput/transaction trade-offs, distributed systems, and schema design.
• Data Pipelines: Designing data pipelines using tools like BigQuery, considering batch and streaming data, online vs. batch predictions, and job automation (e.g., Cloud Composer).
• Data Processing Solutions: Choosing the right infrastructure, ensuring system availability and fault tolerance, utilizing distributed systems, capacity planning, hybrid cloud/edge computing, and event processing (at least once, in-order, exactly once).
• Data Warehousing & Migration: Migrating data warehouses and processing systems, including on-premises to cloud migration strategies (Data Transfer Service, Transfer Appliance, Cloud Networking) and validation.

2. Building and Operationalizing Data Processing Systems:

• Storage Systems: Building and operationalizing storage systems using managed services, optimizing costs and performance, and managing data lifecycles.
• Data Pipelines: Building and operationalizing data pipelines, including data cleansing, batch/streaming processing, transformation, data acquisition, and integration with new data sources.
• Processing Infrastructure: Provisioning resources, monitoring pipelines, adjusting pipelines, and implementing testing and quality control.

3. Operationalizing Machine Learning Models:

• ML as a Service: Leveraging pre-built ML models (e.g., Vision API, Speech API) and customizing them (e.g., AutoML Vision, Auto ML Text).
• ML Pipeline Deployment: Deploying ML pipelines, including data ingestion, model retraining, and continuous evaluation.
• Training & Serving Infrastructure: Choosing appropriate training and serving infrastructure (distributed vs. single machine, edge compute, hardware accelerators).
• ML Model Monitoring: Measuring, monitoring, and troubleshooting ML models, understanding dependencies, and identifying common error sources.

4. Ensuring Solution Quality:

• Security & Compliance: Designing for security and compliance using Identity and Access Management (Cloud IAM), data encryption, key management, privacy (Data Loss Prevention API), and legal compliance.
• Scalability & Efficiency: Building and running test suites, monitoring pipelines (Cloud Monitoring), assessing and improving data representations, and resizing/autoscaling resources.
• Reliability & Fidelity: Ensuring reliability and data quality through data preparation (Dataprep), verification, monitoring, data recovery planning, and choosing appropriate consistency models (ACID, idempotent, eventually consistent).
• Flexibility & Portability: Designing for data and application portability (multicloud, data residency), data staging, cataloging, and discovery.
