   A team has developed a natural-language processing (NLP) system with separate components for tokenization, named-entity recognition (NER), and sentiment analysis. They now want to test how the tokenizer's output affects the NER component's performance, using a small set of annotated texts. Which testing level best matches this activity?

   • AAcceptance testing
   • BComponent integration testing
   • CComponent testing
   • DSystem testing

   Which of the following is typically a focus of component testing for an AI-based system?

   • AEnsuring the AI system meets business requirements and user expectations.
   • BChecking that the AI model integrates correctly with the user interface.
   • CTesting the end-to-end flow from data ingestion to model prediction.
   • DVerifying that the data preprocessing component correctly handles missing values and outliers.

   A team has developed an AI system with three components: data preprocessing, model inference, and post-processing. They have tested each component separately. Now they want to test the interactions between all three components together, but they are unsure whether to do this as component integration testing or system testing. Which statement best distinguishes the two?

   • AComponent integration testing is only for AI systems, while system testing is for traditional software
   • BComponent integration testing focuses on interactions between components, while system testing evaluates the complete system's behavior and performance
   • CComponent integration testing is performed by end users, while system testing is performed by developers
   • DComponent integration testing tests the entire system, while system testing tests individual components

   What is the main objective of component integration testing in an AI-based system?

   • ATo validate the entire system against user acceptance criteria.
   • BTo evaluate the system's performance and reliability under load.
   • CTo test the interfaces and interactions between components to ensure they work together correctly.
   • DTo test each component in isolation to verify its internal logic.
