1 / 20

Question 1

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 2

In Azure Machine Learning, what is the specific purpose of a Compute Instance compared to a Compute Cluster?

A Compute Instance is used exclusively for distributed training of deep learning models, whereas a Compute Cluster is for debugging

A Compute Instance is a fully configured development environment in the cloud used for authoring and testing code, whereas a Compute Cluster is used for scalable batch processing and training jobs

A Compute Instance is serverless and auto-scales based on HTTP traffic, whereas a Compute Cluster is a fixed set of virtual machines

A Compute Instance cannot access storage accounts, whereas a Compute Cluster has native access to Azure Blob Storage

Question 3

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 4

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 5

A human in the loop review is required before AI generated medical advice is published. Which workflow most effectively enforces this control?

Let authors self attest that they reviewed the content

Add a terms of service disclaimer to the website footer

Require a reviewer approval with role based access control and immutable logging before release

Place the model behind VPN

Question 6

Which of the following is a common evaluation metric for classification models?

Accuracy

Mean Squared Error

R-squared

Root Mean Squared Error

Question 7

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 8

Which Microsoft concept ensures AI systems align with security and compliance requirements?

Shadow IT

Responsible AI governance

Open access model

Unrestricted data sharing

Question 9

In reinforcement learning, what does the reward function define?

Desired agent behavior

Dataset size

Learning rate

Neural network depth

Question 10

What is the main role of Microsoft Graph in Copilot for Microsoft 365?

Rendering the user interface

Providing contextual access to organizational data

Training large language models

Encrypting user prompts

Question 11

Which technique is most effective for reducing inference latency in large transformer models?

Increasing dropout

Model quantization

Adding more positional embeddings

Using L2 regularization

Question 12

Which of the following is NOT a common activation function in neural networks?

Sigmoid

ReLU

Linear

Euclidean

Question 13

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

Increasing the learning rate

Adding more hidden layers

Applying dropout regularization

Using a smaller dataset

Question 14

Which Microsoft Azure service is specifically designed for building, training, and deploying machine learning models?

Azure DevOps

Azure Cognitive Services

Azure Machine Learning

Azure Data Factory

Question 15

How do temperature and top_p differ in decoding?

Both set the maximum output length.

They are identical parameters with different names.

Top_p increases creativity while temperature controls factuality.

Temperature scales logits uniformly; top_p samples from the smallest set of tokens whose cumulative probability exceeds p.

Question 16

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 17

In Large Language Models (LLMs), tokenization is used to:

Compress model weights

Convert raw text into numerical representations

Encrypt training data

Optimize GPU utilization

Question 18

What is the primary benefit of using vector databases in AI applications?

Faster relational queries

Semantic similarity search

Reduced storage costs

Improved UI rendering

Question 19

Which Microsoft tool helps govern and protect AI-generated data in Microsoft 365?

Microsoft Purview

Microsoft Defender for Endpoint

Microsoft Sentinel

Azure Monitor

Question 20

Which protocol or technology is commonly used to expose AI models as services?

SMTP

SNMP

FTP

REST API
