Practice Questions: Managing Diverse Data Types for NVIDIA-Certified Professional: Agentic AI
These multiple-choice questions focus on managing diverse data types, a critical skill for the Knowledge Integration and Data Handling section of the NVIDIA-Certified Professional: Agentic AI exam.
Which data type is best suited for representing continuous sensor readings in an agentic AI system?
- A. Categorical data
- B. Time-series data
- C. Textual data
- D. Binary data
Answer: B. Time-series data
Explanation: Continuous sensor readings are sequential and vary over time, making time-series data the most appropriate format for capturing such information.
When integrating external knowledge from heterogeneous sources, which data format requires special handling due to its unstructured nature?
- A. Relational databases
- B. JSON files
- C. Textual documents
- D. CSV files
Answer: C. Textual documents
Explanation: Textual documents are unstructured data requiring natural language processing techniques for effective integration, unlike structured formats like relational databases or CSV files.
Which approach is most effective for handling missing values in numerical datasets used by agentic AI models?
- A. Dropping all rows with missing values
- B. Replacing missing values with the mean or median
- C. Converting missing values to zero
- D. Ignoring missing values during training
Answer: B. Replacing missing values with the mean or median
Explanation: Imputation with mean or median preserves dataset size and reduces bias, making it a common practice for numerical data preprocessing.
Which data type requires encoding techniques such as one-hot encoding before being used in most machine learning models?
- A. Numerical data
- B. Categorical data
- C. Image data
- D. Time-series data
Answer: B. Categorical data
Explanation: Categorical data must be converted into numerical representations like one-hot encoding to be processed by machine learning algorithms.
What is the primary challenge when integrating multimodal data (e.g., text, images, and sensor data) in agentic AI systems?
- A. Data volume
- B. Data labeling
- C. Data format heterogeneity
- D. Data storage costs
Answer: C. Data format heterogeneity
Explanation: Multimodal data comes in diverse formats requiring specialized preprocessing and alignment methods to enable effective integration.
Which data handling technique helps improve the efficiency of processing large-scale image datasets for agentic AI?
- A. Data normalization
- B. Data augmentation
- C. Data compression
- D. Data shuffling
Answer: C. Data compression
Explanation: Compressing image data reduces storage and bandwidth requirements, facilitating faster processing without significant loss of quality.
In the context of agentic AI, why is metadata important when managing diverse data types?
- A. It reduces data storage size
- B. It provides context and provenance information
- C. It encrypts sensitive data
- D. It converts data into numerical form
Answer: B. It provides context and provenance information
Explanation: Metadata describes data attributes and origin, which is essential for data governance, integration, and ensuring data quality.
