You are testing a mission-critical database for a financial institution. During the test, you observe that the database response time significantly increases as the number of concurrent users grows. Which type of testing should you perform to address this issue?
- Load Testing
- Performance Testing
- Scalability Testing
- Stress Testing
Performance Testing
Test script execution should include ____________ to verify the expected outcomes.
- Assertions
- Validations
- Inspections
- Verifications
The correct option is "Verifications." Test script execution should include verifications to validate that the expected outcomes are met. Verifications involve comparing the actual results of the executed test script with the expected outcomes specified beforehand. This ensures that the database behaves as intended and that any deviations from expected behavior are detected and addressed promptly.
In authorization testing, the principle of "least ____________" is a security practice that grants users the minimum access required to perform their tasks.
- Access
- Authority
- Permission
- Privileges
The principle of "least privilege" ensures that users have the minimum level of access necessary to accomplish their tasks. This practice reduces the risk of unauthorized access and potential security breaches.
In database testing, automation frameworks facilitate the creation of reusable ____________ for common testing scenarios.
- test cases
- test data
- test plans
- test scripts
Automation frameworks aid in the creation of reusable test data for recurring testing scenarios. This improves efficiency by eliminating the need to recreate test data for each test cycle.
What is the purpose of database query optimization in performance testing?
- Enhance database security
- Improve query efficiency
- Increase database size
- Reduce database redundancy
The purpose of database query optimization in performance testing is to improve query efficiency. By optimizing queries, database performance can be enhanced, leading to faster response times, reduced resource consumption, and improved overall system performance. Query optimization techniques include index usage, query rewriting, and database schema tuning.
Which metric helps identify the percentage of test cases that have been executed but are still failing?
- Defect Density
- Test Case Effectiveness
- Test Coverage
- Test Execution Effectiveness
Test coverage metric helps in identifying the percentage of test cases that have been executed but are still failing. It measures the extent to which the application has been tested by comparing the number of executed test cases to the total number of test cases defined in the test plan. A high test coverage percentage indicates that a significant portion of the application has been tested, while a low test coverage percentage suggests inadequate testing. By monitoring test coverage, testers can prioritize testing efforts, identify areas with insufficient coverage, and ensure comprehensive testing of the application. This metric is essential for assessing the thoroughness and effectiveness of the testing process.
What is the difference between symmetric and asymmetric encryption, and which one is commonly used in database encryption?
- Asymmetric encryption uses different keys for encryption and decryption.
- Both encryption methods use different keys for encryption and decryption.
- Symmetric encryption is commonly used in database encryption.
- Symmetric encryption uses a single key for both encryption and decryption.
Symmetric encryption uses a single key for both encryption and decryption, making it faster and more efficient for large volumes of data. Asymmetric encryption, on the other hand, uses a pair of keys (public and private) which makes it slower but more secure. Symmetric encryption is commonly used in database encryption because it provides faster processing times, essential for handling large amounts of data in databases.
Which phase of the SDLC (Software Development Life Cycle) typically includes database testing?
- Deployment Phase
- Development Phase
- Planning Phase
- Testing Phase
Database testing is typically performed during the Testing Phase of the SDLC. This phase involves validating the functionality and performance of the system, including its interaction with the database. Database testing ensures that data is stored, retrieved, and manipulated correctly according to the application's requirements.
Access control testing ensures that only authorized users have ____________ to specific database resources.
- Read
- Access
- Rights
- Permissions
Access control testing is a crucial aspect of database security. It focuses on verifying that only users with the appropriate authorization can access specific resources within the database. Therefore, the correct option is "Access."
What challenges are typically associated with handling large volumes of data in ETL testing?
- Data security vulnerabilities, compliance issues, and data loss risks.
- Lack of testing tools, inadequate documentation, and version control problems.
- Limited scalability, data corruption, and interoperability issues.
- Performance bottlenecks, increased processing time, and resource constraints.
Handling large volumes of data in ETL testing poses several challenges such as performance bottlenecks due to increased processing time, resource constraints, and scalability issues. These challenges can impact the efficiency and effectiveness of the ETL process, leading to delays and potential data inconsistencies.
