Which component is responsible for executing test scripts in a database testing framework?
- Database administrator
- Test case manager
- Test data generator
- Test execution engine
The test execution engine is the component responsible for executing test scripts in a database testing framework. It interprets the instructions provided in the scripts and interacts with the database to perform the specified actions. The engine also captures and reports the results of the test execution, facilitating analysis and decision-making.
During the ETL process, the "Transform" phase involves data ____________ to make it suitable for the target system.
- Cleansing
- Extraction
- Validation
- Manipulation
The "Transform" phase in ETL (Extract, Transform, Load) involves manipulating data to ensure it aligns with the structure and requirements of the target system. This can include tasks such as data cleansing, enrichment, aggregation, and normalization. Thus, the correct option is "Manipulation."
Scenario: Your organization is required to comply with the Sarbanes-Oxley Act (SOX) for financial reporting. During the compliance testing process, you discover that critical financial data is susceptible to unauthorized modifications. What measures should you implement to enhance data integrity and SOX compliance?
- Delete the critical financial data to avoid non-compliance with SOX regulations.
- Encrypt the critical financial data to prevent unauthorized access and modifications.
- Implement strict access controls and audit trails to track changes made to critical financial data.
- Share the critical financial data with all employees to ensure transparency and accountability.
SOX compliance requires organizations to ensure the integrity and accuracy of financial data. Implementing strict access controls and audit trails helps to track changes made to critical financial data, identify unauthorized modifications, and maintain data integrity. By monitoring and recording all access and modifications, organizations can demonstrate compliance with SOX requirements and mitigate the risk of financial fraud or errors.
Which type of report provides insights into the stability of a software application by tracking defects over time?
- Defect density report
- Defect trend report
- Test coverage report
- Test summary report
The "defect trend report" provides insights into the stability of a software application by tracking defects over time. This report helps stakeholders understand how the number and severity of defects change throughout the testing process and after releases. By analyzing the trends in defect occurrence and resolution, teams can identify patterns, assess the effectiveness of their testing efforts, and make informed decisions to improve product quality.
In ETL testing, what is the primary goal of data validation?
- Checking data consistency
- Detecting data duplication
- Ensuring accuracy
- Validating data transformation
Data validation in ETL testing primarily aims at ensuring accuracy by verifying that the data is correctly transformed and loaded into the target system.
You are testing a database system used for an e-commerce platform. Customers have reported that their order history sometimes displays incorrect information, such as duplicate orders. Which type of testing would be most suitable to identify and resolve this data consistency issue?
- Data Consistency Testing
- Integration Testing
- Performance Testing
- Unit Testing
Data Consistency Testing involves verifying the integrity, accuracy, and consistency of data in the database. It checks for anomalies such as duplicate records, missing data, or inconsistent values, making it suitable for identifying and resolving issues like duplicate orders in the order history.
Scenario: You are testing the scalability of a popular e-commerce website during a sale event. The website experiences a sudden surge in traffic, and the response time degrades significantly. Which type of scalability testing should you have conducted to prevent this issue?
- Load Testing
- Performance Testing
- Spike Testing
- Stress Testing
Spike Testing is a type of scalability testing that evaluates how a system handles sudden spikes or surges in traffic. Unlike gradual increases in load, spike testing specifically focuses on abrupt changes, simulating real-world scenarios such as flash sales or breaking news events. Conducting spike testing helps identify potential bottlenecks and weaknesses in the system under extreme conditions, allowing for better preparedness and optimization before such events occur.
In ETL testing, the process of transforming data from source to target is known as ____________.
- Extraction
- Loading
- Migration
- Transformation
Transformation is the stage in ETL (Extract, Transform, Load) process where data is converted or modified according to business rules and requirements before loading it into the target system.
Which Ethernet standard is commonly used for Gigabit Ethernet in most modern local area networks?
- 10Base-T
- 100Base-FX
- 1000Base-T
- 100Base-T
Gigabit Ethernet in most modern local area networks commonly uses the 1000Base-T standard, which operates at 1 Gbps (1000 Mbps) over twisted-pair cabling, such as Cat 5e or Cat 6.
Imagine you're monitoring a network and notice that a client sends a SYN packet but doesn't receive a SYN-ACK response from the server. Instead, the client keeps retransmitting the SYN packet. What might be a likely reason for this behavior?
- Firewall Blocking
- MTU Mismatch
- Network Congestion
- Wrong IP Address
Network Congestion is a common reason for a client not receiving a SYN-ACK response. When the network is congested, packets may be dropped or delayed, leading to retransmissions. A SYN-ACK is the second step in the TCP three-way handshake, and if it's not received, the client will retransmit the SYN packet.
