🤖

Topic 1 — Foundations of Artificial Intelligence

What AI is, how it works, types of AI, and real-world applications

Question 01

Which of the following best describes the goal of Artificial Intelligence?

ATo replace all human workers with machines permanently
BTo create systems that can perform tasks requiring human-like intelligence such as reasoning, learning, and problem solving ✅
CTo build faster computers with more processing power
DTo develop new programming languages for developers
💡 ExplanationArtificial Intelligence is the broad field of computer science focused on building systems capable of performing tasks that normally require human intelligence — such as understanding language, recognizing images, making decisions, and solving complex problems.

Question 02

What is the difference between Narrow AI and General AI?

ANarrow AI performs specific tasks while General AI can perform any intellectual task a human can do ✅
BNarrow AI is more powerful than General AI
CGeneral AI already exists and is used in smartphones today
DNarrow AI requires more data than General AI to function
💡 ExplanationAll AI systems today are Narrow AI — they excel at one specific task like playing chess, translating text, or recognizing images. General AI (AGI) — a system with human-level reasoning across all domains — does not yet exist and remains a long-term research goal.

Question 03

Which of the following is a real-world example of AI being used in healthcare?

AUsing spreadsheets to record patient appointments
BSending automated email reminders to patients
CUsing deep learning models to detect cancer in medical images with high accuracy ✅
DPrinting patient records in a hospital
💡 ExplanationAI is transforming healthcare — deep learning models trained on thousands of X-rays and MRI scans can now detect cancers, diabetic retinopathy, and other conditions as accurately as or better than specialist doctors, enabling earlier diagnosis and better patient outcomes.

Question 04

What are the three main subfields that fall under Artificial Intelligence?

ACoding, databases, and networking
BMachine Learning, Natural Language Processing, and Computer Vision ✅
CCloud computing, cybersecurity, and blockchain
DHTML, CSS, and JavaScript
💡 ExplanationThe three core subfields of AI most tested in the IBM AI Fundamentals certification are Machine Learning (learning from data), Natural Language Processing (understanding human language), and Computer Vision (interpreting images and video).
 

🧠

Topic 2 — Machine Learning Concepts

Algorithms, training, model evaluation, and IBM AutoAI

Question 05

What is the purpose of a “decision tree” algorithm in machine learning?

ATo store data in a hierarchical file system
BTo make decisions by splitting data into branches based on feature values, leading to a final classification or prediction ✅
CTo grow real trees in an environmental simulation program
DTo organize neural network layers into tree structures
💡 ExplanationA decision tree is a supervised ML algorithm that creates a tree-like model of decisions. At each node it asks a question about a feature and branches based on the answer. It is highly interpretable and widely used in fraud detection, medical diagnosis, and customer segmentation.

Question 06

What is clustering in unsupervised machine learning?

AGrouping similar models together for deployment
BSplitting training data into smaller batches for faster processing
CAutomatically grouping data points that share similar characteristics without using predefined labels ✅
DCombining multiple neural networks into a single large model
💡 ExplanationClustering is a core unsupervised learning technique. The algorithm groups similar data points together without human-labeled categories. It is commonly used in customer segmentation, document categorization, and detecting unusual patterns in data.

Question 07

What is IBM AutoAI in IBM Watson Studio?

AAn automated tool that writes Python code for data scientists
BA tool that automatically prepares data, selects algorithms, and builds the best ML pipeline with minimal manual effort ✅
CAn IBM chatbot that answers customer support questions
DA system that automatically deploys applications to IBM Cloud
💡 ExplanationIBM AutoAI is IBM’s automated machine learning tool within Watson Studio. It automatically handles feature engineering, algorithm selection, and hyperparameter tuning — allowing non-experts to build high-quality ML models without writing any code.
 

💬

Topic 3 — Natural Language Processing

How machines understand, interpret, and generate human language

Question 08

What does Natural Language Processing (NLP) enable a computer to do?

ADisplay text on a screen in multiple fonts
BUnderstand, interpret, and generate human language in a meaningful and contextually relevant way ✅
CProcess only structured numerical data in spreadsheets
DConvert images to text using optical character recognition only
💡 ExplanationNLP bridges the gap between human language and computer understanding. It powers applications like virtual assistants, real-time translation, email spam filters, sentiment analysis tools, and chatbots that hold natural conversations.

Question 09

What is “tokenization” in Natural Language Processing?

AA security method used to protect API keys in NLP systems
BThe process of encrypting text data before sending it to an AI model
CBreaking text into smaller units such as words, subwords, or characters so the model can process them individually ✅
DConverting text from one language to another automatically
💡 ExplanationTokenization is the first step in most NLP pipelines. It breaks raw text into tokens — which can be whole words, parts of words, or individual characters — so the model can analyze and understand the structure of language mathematically.

Topic 4 — Computer Vision

How AI sees, understands, and interprets images and video

Question 10

What is computer vision?

ASoftware that corrects vision problems in human eyes
BA field of AI that trains computers to interpret and understand visual information from images and videos ✅
CA type of display screen technology used in AI labs
DA programming interface for controlling camera hardware
💡 ExplanationComputer vision enables machines to see and understand the visual world. It powers face recognition, autonomous vehicles, quality control in manufacturing, medical imaging analysis, and augmented reality applications.

Question 11

What is a Convolutional Neural Network (CNN) primarily used for?

AProcessing time-series data and financial forecasts
BBuilding conversational chatbots and virtual assistants
CProcessing and classifying images and videos by detecting patterns, edges, and features ✅
DGenerating written reports from structured spreadsheet data
💡 ExplanationCNNs are the foundation of modern computer vision. They use convolutional layers to scan images and detect features like edges, shapes, and textures at different levels of abstraction — making them the go-to architecture for image classification, object detection, and face recognition.

Question 15

What does “explainable AI” (XAI) mean?

AAI that can explain itself verbally to users in real time
BAI systems designed so that their decisions and predictions can be understood and interpreted by humans ✅
CAI that only works on problems with simple explanations
DAI that requires human explanation before it can process any input
💡 ExplanationExplainable AI (XAI) is critical in high-stakes domains like healthcare, finance, and legal systems where people need to understand why an AI made a specific decision. IBM’s AI Fairness 360 and Watson OpenScale are tools built to support model explainability and bias detection.

Question 16

According to IBM’s AI ethics framework, who is ultimately responsible for an AI system’s decisions?

AThe AI system itself since it made the decision autonomously
BThe cloud provider hosting the AI model
CThe data scientists who built the training dataset
DThe humans and organizations that design, deploy, and use the AI system ✅
💡 ExplanationIBM firmly believes that AI is a tool and humans are always accountable for its use. The designers who build it, the organizations that deploy it, and the professionals who use it all share responsibility for ensuring AI decisions are fair, ethical, and beneficial to society.
