________ is a technique used to identify test cases that examine the boundaries of input ranges.
- Boundary Value Analysis
- Decision Table Testing
- Equivalence Partitioning
- State Transition Testing
Boundary Value Analysis is a technique used to identify test cases that examine the boundaries of input ranges. This helps ensure that the application handles inputs at the edge conditions effectively.
How does the 'Test Closure' phase contribute to the overall Test Execution Lifecycle?
- It deals with test environment setup
- It focuses on defect resolution
- It initiates test planning
- It marks the end of testing activities
The 'Test Closure' phase marks the end of testing activities. It involves formalizing test results, obtaining stakeholders' approval, and preparing the final test closure report.

In ETL testing, automated scripts can be reused for ________ testing.
- Integration
- Performance
- Regression
- User Acceptance
In ETL testing, automated scripts can be reused for Regression testing. This type of testing ensures that new changes or enhancements do not negatively impact existing functionalities. Automated scripts help in quickly validating the entire ETL process after modifications.
Testing for ________ is crucial when integrating streaming data with traditional data sources.
- Concurrency
- Data Consistency
- Data Quality
- Latency
Testing for Latency is crucial when integrating streaming data with traditional data sources. Latency measures the time delay between data generation and its availability for processing, a critical aspect in real-time integration.
What role does data deduplication play in optimizing data loading strategies?
- Decreases storage space and improves performance
- Enhances data integrity
- Increases data redundancy
- Slows down the data loading process
Data deduplication plays a crucial role in optimizing data loading strategies by decreasing storage space requirements and improving performance. It identifies and eliminates duplicate records, ensuring data accuracy and reducing the overall volume to be loaded.
When testing a data lake for a healthcare application, what specific aspects should be emphasized to ensure compliance with regulatory standards?
- Audit Trail and Logging Testing
- Data Privacy and Confidentiality Testing
- Data Quality and Integrity Testing
- Data Retention and Archiving Testing
Testing a data lake for a healthcare application should emphasize Data Privacy and Confidentiality Testing. This ensures that sensitive healthcare data is handled securely, maintaining compliance with regulatory standards such as HIPAA.
In complex data environments, ________ is used to validate and verify data across different systems.
- Data Aggregation
- Data Reconciliation
- Data Replication
- Data Synchronization
Data Reconciliation is employed in complex data environments to validate and verify data across different systems. It ensures consistency and accuracy by comparing data in various systems and identifying discrepancies.
What is the significance of data masking in ETL test environment setup?
- Data masking helps protect sensitive information during testing
- Data masking increases data accuracy in the ETL process
- Data masking is not significant in ETL testing
- Data masking slows down the ETL testing process
Data masking is significant in ETL test environment setup as it helps protect sensitive information during testing. By obfuscating or replacing sensitive data with realistic but fictitious data, testers can ensure compliance with data privacy regulations while still conducting thorough testing.
