Designing AI solutions is a key domain of the AI-102 exam, and it tests your ability to understand business requirements and translate them into AI-based solutions. This section requires knowledge of different AI services available within Microsoft Azure and the ability to select the right tool for a given scenario.

Understanding the Business Requirements

To begin with, when approaching any AI project, it is crucial to gather and understand the business requirements. This includes working closely with stakeholders to determine their needs and expectations from the AI solution. The business requirements drive the design of the solution, as they dictate what kind of AI models and services will be implemented.

You should also know how to assess whether AI is the best solution for the problem at hand. Sometimes, business requirements may not necessarily need AI; simpler automation or business intelligence solutions may be more cost-effective and easier to implement. In the exam, you will be presented with scenarios where you have to identify whether AI is the right solution and which Azure services would fit the requirements.

Selecting the Right Azure AI Services

The AI-102 exam requires you to understand the various Azure AI services, such as Azure Cognitive Services, Azure Machine Learning, and Azure Databricks. Each service has its own set of features, and knowing which service to use is crucial for designing the right solution.

For example, Azure Cognitive Services is a collection of pre-built AI models that can be used for speech recognition, image analysis, and text processing. These services are ideal when you need AI capabilities without building models from scratch. Azure Machine Learning, on the other hand, allows you to develop custom models, train them with your own data, and deploy them into production. You may also use Azure Databricks for big data analytics and machine learning workflows.

Understanding the strengths and weaknesses of each service will help you design an optimal AI solution for your business.

Choosing an Architecture for AI Solutions

The architecture of the solution will vary depending on the requirements of the business. Azure provides several services for creating scalable and flexible architectures. Services like Azure Kubernetes Service (AKS) allow you to deploy machine learning models as containers for easy scaling and orchestration. If you are building a data-driven AI solution, services such as Azure SQL Database or Azure Data Lake Storage can be used for storing and processing large datasets.

In addition, understanding how to integrate different Azure services is crucial. For example, you might need to integrate Azure Cognitive Services with custom machine learning models in Azure Machine Learning to create a hybrid solution that uses both pre-built models and custom-built models.

Implementing AI Solutions (25–30%)

After designing the AI solution, the next step is to implement it. This domain of the exam tests your ability to deploy machine learning models, set up cloud services, and ensure that the solution is functioning as expected.
