General Practice Questions

QUESTION 1

What is data masking?

  • A. Compressing data to reduce file size.
  • B. Encrypting data for protection.
  • C. Replacing sensitive data with realistic but non-sensitive values.
  • D. Deleting data to conserve storage.
Click to View Verified Solution & Explanation

Correct Option: C

Explanation:

Data masking is a technique used to create a realistic, structurally similar, but inauthentic version of data. Its primary purpose is to protect sensitive actual data by replacing it with fictitious but plausible values, typically for use in non-production environments like testing, development, or training. This allows users to work with data that mimics production data without exposing real sensitive information.

Why the other choices are incorrect:

  • Option A is incorrect: Data compression focuses on reducing the size of data to save storage space or bandwidth, not on obfuscating sensitive information.
  • Option B is incorrect: Encrypting data transforms it into an unreadable format that requires a key for decryption. While it protects data, it’s different from masking, which creates usable, albeit fake, data.
  • Option D is incorrect: Deleting data removes it permanently from storage. This eliminates the data entirely, rather than replacing sensitive parts with non-sensitive substitutes.

QUESTION 2

Which statement is true about Convolutional Neural Networks (CNNs)?

  • A. They can process all data types.
  • B. They generally achieve higher accuracy on image data.
  • C. They are the only existing type of neural network.
  • D. They require more data then traditional neural networks for image prediction.
Click to View Verified Solution & Explanation

Correct Option: B

Explanation: Convolutional Neural Networks (CNNs) are specifically architected to process grid-like data, such as images. Their convolutional layers automatically learn hierarchical features from the input data, making them exceptionally effective for image recognition, object detection, and other computer vision tasks. This specialized architecture allows CNNs to achieve significantly higher accuracy on image data compared to traditional neural networks that treat images as flat vectors. A is incorrect because CNNs are optimized for specific data types like images, not all data types. C is incorrect as many other neural network types exist, such as Recurrent Neural Networks (RNNs) and Multilayer Perceptrons (MLPs). D is incorrect; while deep CNNs can benefit from large datasets, they often learn more efficiently and achieve better performance on image tasks with adequate data than traditional neural networks, which struggle with the high dimensionality of image data.

QUESTION 3

A legal consultancy requires a model to draft documents based on a highly specialized and largely static body of legal precedent.

Which approach is most appropriate?

  • A. A small classification model trained on labeled legal cases
  • B. Fine-tuning a model trained on the legal precedent data
  • C. Retrieval-augmented generation with access given to the legal precedent data
  • D. Using a generic foundation model without any adaptation
Click to View Verified Solution & Explanation

Correct Option: C

Explanation:

✅ Option C (Correct)
Reasoning: Retrieval-augmented generation (RAG) is the most appropriate approach for drafting documents based on a highly specialized and largely static body of legal precedent. RAG models combine a retrieval component with a generative language model, allowing them to search a defined knowledge base (the legal precedent data) for relevant information and then use that information to generate accurate and contextually appropriate text. This approach ensures that the generated documents are grounded in specific facts and precedents, minimizing hallucination and maintaining factual accuracy.

❌ Why the other choices are incorrect:

  • Option A is incorrect: A classification model is designed to categorize inputs, not to generate comprehensive documents. It would not be suitable for drafting legal text.
  • Option B is incorrect: While fine-tuning could adapt a model to the legal domain, it still risks hallucination and might not accurately cite specific precedents without a direct retrieval mechanism. It also requires significant computational resources and could lead to ‘catastrophic forgetting’ of general knowledge.
  • Option D is incorrect: A generic foundation model without any adaptation would lack the specialized legal knowledge required to draft documents based on specific precedents, likely producing irrelevant or inaccurate content.

QUESTION 4

Which the primary goal of explainability in Al systems?

  • A. To help users understand how the system arrives at decisions.
  • B. To provide internet connectivity for the system.
  • C. To enable Al systems to learn directly from human feedback.
  • D. To increase processing speed and efficiency.
Click to View Verified Solution & Explanation

Correct Option: A

Explanation:

To help users understand how the system arrives at decisions is the primary goal of explainability in AI systems. Explainable AI (XAI) focuses on making AI models transparent and interpretable, allowing stakeholders to comprehend the rationale behind an AI’s output. This understanding is crucial for building trust, ensuring fairness, debugging models, and complying with regulatory requirements. Without explainability, complex AI models often operate as ‘black boxes,’ making it difficult to assess their reliability or potential biases.

Reference: https://www.ibm.com/topics/explainable-ai

QUESTION 5

What is the primary difference between a Large Language Model (LLM) and a Foundation Model?

  • A. A Foundation Model is a subtype of LLM for general-purpose tasks.
  • B. A LLM is trained from scratch, while a Foundation Model is pre-trained.
  • C. A LLM focuses only on text generation, while Foundation Models serve broader tasks.
  • D. A LLM is a type of Foundation Model specifically designed for natural language tasks.
Click to View Verified Solution & Explanation

Correct Option: D

Explanation:

✅ Option D (Correct)Reasoning: A Large Language Model (LLM) is a specialized type of Foundation Model. Foundation Models are broad, large-scale AI models trained on vast datasets, designed to be adaptable to various tasks across different modalities (text, image, audio, etc.). An LLM specifically applies this concept to natural language processing, being trained on extensive text data to understand, generate, and interact with human language. Therefore, an LLM is a subset or specific instance of a Foundation Model focused on natural language tasks.❌ Why the other choices are incorrect:

  • Option A is incorrect: This reverses the relationship. An LLM is a subtype of a Foundation Model, not the other way around. Foundation Models encompass more than just LLMs.
  • Option B is incorrect: Both LLMs and Foundation Models are typically ‘pre-trained’ on large datasets. The distinction is not about one being trained from scratch and the other pre-trained; rather, both leverage pre-training.
  • Option C is incorrect: While LLMs excel at text generation, they also perform various other natural language tasks like understanding, summarization, translation, and question-answering. The statement incorrectly narrows the scope of LLMs.

Reference: https://www.ibm.com/topics/foundation-models

QUESTION 6

Which concept ensures that Al systems comply with internal policies and external regulations throughout development and deployment?

  • A. Governance
  • B. Robustness
  • C. Explainability
  • D. Transparency
Click to View Verified Solution & Explanation

Correct Option: A

Explanation:

Option A is correct: AI Governance provides the foundational framework of policies, procedures, and oversight mechanisms to ensure that AI systems comply with both internal organizational policies and external legal and regulatory requirements. This comprehensive approach covers the entire AI lifecycle, from initial development and training to deployment and ongoing monitoring, ensuring responsible, ethical, and compliant AI deployment.

Why the other choices are incorrect:

  • Option B (Robustness) is incorrect: Robustness refers to an AI system’s ability to maintain its performance and accuracy when exposed to varied, noisy, or adversarial input data. It focuses on the system’s resilience rather than its compliance with policies and regulations.
  • Option C (Explainability) is incorrect: Explainability (or interpretability) is the ability to understand how an AI system arrived at a particular decision or prediction. While crucial for auditing and trust, it is a characteristic of an AI system, not the overarching concept for ensuring policy and regulatory compliance.
  • Option D (Transparency) is incorrect: Transparency in AI refers to making the internal workings, data, and decision-making processes of AI systems visible and understandable to stakeholders. While it contributes to accountability, governance is the broader concept that actively manages and enforces compliance with policies and regulations.

QUESTION 7

Unsupervised learning algorithms are best suited for which type of data?

  • A. Structured
  • B. Hybrid
  • C. RL Decoupled
  • D. Unstructured
Click to View Verified Solution & Explanation

Correct Option: D

Explanation: Unsupervised learning algorithms are specifically designed to find patterns and structures in data without the need for explicit labels. This makes them exceptionally well-suited for unstructured data, such as text, images, audio, or video, where data is often unlabeled and its underlying structure is not predefined. Algorithms like clustering, dimensionality reduction, and association rule mining excel at discovering hidden insights in such datasets. Structured data, while usable, often benefits from supervised methods when labels are available. Hybrid and RL Decoupled are not standard data types in this context.

Reference: https://www.ibm.com/cloud/learn/unsupervised-learning

QUESTION 8

Which class of algorithms does the image below fall under?

  • A. Deep Learning
  • B. Graph Neural Networks
  • C. Classical
  • D. Unsupervised Learning
Click to View Verified Solution & Explanation

Correct Option: C

Explanation:

The image displays a decision tree, which is a fundamental algorithm used for classification. Decision trees are a core component of classical machine learning algorithms. They operate by recursively splitting data based on feature values to make a final prediction or decision. This approach is distinct from more recent paradigms like deep learning or specialized graph neural networks.

Why the other choices are incorrect:

  • Option A is incorrect: Deep Learning involves neural networks with multiple hidden layers, which is not represented by the flowchart structure shown.
  • Option B is incorrect: Graph Neural Networks are designed to process data structured as graphs, focusing on relationships between nodes. While a decision tree has a graph-like structure, the algorithm itself is not a GNN.
  • Option D is incorrect: Unsupervised Learning deals with finding patterns in unlabeled data (e.g., clustering). The decision tree in the image is making a predictive decision (‘Surf’ or ‘Don’t surf’) based on input conditions, which is characteristic of supervised learning.

Reference: https://www.ibm.com/topics/decision-tree

QUESTION 9

Why is data normalization important in machine learning?

  • A. It generates new input features.
  • B. It brings all features to a consistent scale.
  • C. It reduces the number of input features.
  • D. It helps select the most relevant data attributes.
Click to View Verified Solution & Explanation

Correct Option: B

Explanation:

✅ Option B (Correct)
Reasoning: Data normalization is a critical preprocessing step in machine learning that scales numerical features to a standard range (e.g., 0 to 1 or a standard normal distribution). This process brings all features to a consistent scale, preventing features with larger magnitudes from dominating the learning algorithm. Many machine learning algorithms, such as gradient descent, K-nearest neighbors, and support vector machines, are sensitive to the scale of input features, and normalization ensures they perform optimally and converge more efficiently.

❌ Why the other choices are incorrect:

  • Option A is incorrect: Normalization transforms existing features’ scales; it does not generate new input features. Generating new features is part of feature engineering.
  • Option C is incorrect: Normalization does not reduce the number of input features. Dimensionality reduction or feature selection techniques are used to decrease the number of features.
  • Option D is incorrect: While normalization can improve model performance, its primary purpose is not to select the most relevant data attributes. That task falls under feature selection methods.
