Question 1

In the context of reinforcement learning, what does the term “exploration vs. exploitation” refer to?

The trade-off between trying out new actions to discover their effects and selecting the best-known action to maximize reward

The process of balancing the number of layers in a neural network

The decision between using supervised or unsupervised learning techniques

The choice between using CPU or GPU for model training

Question 2

In ResNet architectures, what problem do skip connections (residual connections) primarily address?

Reducing the number of trainable parameters

Eliminating the need for batch normalization

Mitigating vanishing gradient problem in very deep networks

Increasing receptive field size without additional layers

Question 3

What is a key benefit of using AI in IT operations (AIOps)?

Increased manual tasks

Faster incident detection and resolution

Reduced logging

Less automation

Question 4

What’s the safest stance on chain‑of‑thought (CoT) for enterprise users?

CoT guarantees factual accuracy regardless of sources.

Always demand full internal reasoning for maximum transparency.

Ask for brief, reproducible reasoning steps or citations—not verbatim hidden reasoning—to avoid over‑disclosure and maintain auditability.

Ban any explanation; only accept final answers.

Question 5

Which Azure service is primarily used to create, train, and deploy custom machine learning models at scale?

Azure Cognitive Services

Azure Machine Learning workspace

Azure Bot Service

Azure Stream Analytics

Question 6

Which statements about Parameter-Efficient Fine-Tuning (PEFT) methods like LoRA are correct?

They freeze the base model weights and train small adapter layers

They significantly reduce memory requirements during fine-tuning

They always achieve better performance than full fine-tuning

They enable efficient multi-task adaptation with separate adapters

Question 7

What’s a robust way to detect unsupported claims in generated outputs?

Disable citations to reduce confusion.

Count how many times the model says ‘according to’.

Run a claim‑verification pass that aligns extracted statements with cited sources; flag any statements lacking evidence.

Prefer longer outputs with more citations.

Question 8

Which concept best describes an AI system’s ability to explain its decisions in a human-understandable way?

Generalization

Interpretability

Automation

Scalability

Question 9

What does Microsoft recommend to control access to AI features like Copilot?

Manual user approval

Role-Based Access Control and Conditional Access

Local admin permissions

Disabling MFA

Question 10

What is the primary role of a GPU in AI workloads?

To store large datasets

To accelerate parallel computations required for training neural networks

To manage network traffic

To improve database indexing

Question 11

Which scenario best represents a responsible use of AI like Copilot in the enterprise?

Allowing Copilot to publish content without review

Using Copilot to assist users while keeping human validation and governance controls

Disabling all security controls to improve AI accuracy

Replacing compliance processes with AI automation only

Question 12

What control most effectively reduces privacy risk while preserving utility when fine tuning a LLM with customer emails that include personal data?

Aggregate emails into topic clusters and discard original texts before training

Use synthetic data generated for the LLM instead of real emails

Tokenize emails and remove all entities with simple regex patterns

Apply structured pseudonymization for direct identifiers and keep semantics via entity placeholders

Question 13

How does the vanishing gradient problem most directly impact the training of very deep neural networks?

It causes gradients to grow exponentially in deeper layers

It increases the memory footprint during deployment

It leads to unstable loss values during inference

It prevents effective learning in layers close to the input

Question 14

When switching to a different embedding model, what must you plan for?

Re‑indexing/re‑embedding the corpus because vector spaces are model‑specific.

Only updating metadata, since numeric vectors remain compatible.

No changes; all embedding models share the same vector space.

Regenerating citations but not the index.

Question 15

What is the main advantage of using a pre-trained model in AI development?

It guarantees 100% accuracy

It reduces training time and computational resources

It eliminates the need for data preprocessing

It prevents bias in datasets

Question 16

Which feature helps organizations track how Copilot is being used across Microsoft 365?

Windows Event Viewer

Microsoft 365 Audit Logs and Usage Reports

Task Manager

PowerShell ISE

Question 17

What is the role of Azure OpenAI Service?

Provide physical AI hardware

Offer OpenAI models with enterprise security and compliance

Replace Azure Active Directory

Perform data backups

Question 18

When deploying an Azure Machine Learning model for real‑time inference, the recommended endpoint type is:

Batch Endpoint

Managed Online Endpoint

Azure Kubernetes Service only

Storage Account Trigger

Question 19

In Azure AI Search: What is the advantage of "Vector Search" compared to classic full-text search?

It requires no indexing

It finds results based on semantic similarity rather than just keywords

It is always free

It only works with image files

Question 20

Which technique is most effective for reducing overfitting in deep neural networks?

Dropout regularization

Removing activation functions

Increasing learning rate

Using fewer training samples
