<\/strong><\/h3>\n\n\n\n<p><strong>1. What are the main types of AI workloads, and how do they differ in terms of infrastructure requirements?<\/strong><\/p>\n\n\n\n<p><strong>Sample Answer:<\/strong> AI workloads generally fall into four categories: data preparation, model training, model evaluation, and inference.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Data preparation is I\/O-intensive and requires high storage throughput.<\/li>\n\n\n\n<li>Training is compute-intensive, often requiring GPUs or TPUs to handle large matrix operations efficiently.<\/li>\n\n\n\n<li>Evaluation is a mix of compute and storage.<\/li>\n\n\n\n<li>Inference demands low-latency compute, especially for real-time applications.<br>Infrastructure choices must balance compute, storage, and networking based on workload type.<\/li>\n<\/ul>\n\n\n\n<p><strong>2. How do training and inference workloads differ in performance and resource requirements?<\/strong><\/p>\n\n\n\n<p><strong>Sample Answer:<\/strong> Training is highly resource-intensive, involving iterative computations on large datasets. It benefits from parallel processing using GPUs or distributed systems.<br>Inference, on the other hand, is about applying a trained model to new data. It requires less compute but demands low latency and sometimes edge deployment for responsiveness. Cost, latency, and scalability are key considerations when choosing infrastructure for each.<\/p>\n\n\n\n<p><strong>3. What are key considerations when selecting storage solutions for AI workloads?<\/strong><\/p>\n\n\n\n<p><strong>Sample Answer:<\/strong> AI workloads require scalable, high-throughput storage. Considerations include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Performance: Use SSDs or parallel file systems for fast access.<\/li>\n\n\n\n<li>Scalability: Object storage like Amazon S3 is ideal for large datasets.<\/li>\n\n\n\n<li>Cost: Tiered storage (hot vs cold) helps optimize expenses.<\/li>\n\n\n\n<li>Compatibility: Storage must integrate with frameworks like TensorFlow or PyTorch.<\/li>\n\n\n\n<li>Latency: Local storage is better for training; object storage can suffice for archival or batch tasks.<\/li>\n<\/ul>\n\n\n\n<p><strong>4. How do you decide between using CPUs, GPUs, and TPUs for AI workloads?<\/strong><\/p>\n\n\n\n<p><strong>Sample Answer:<\/strong> It depends on the workload type and scale:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>CPUs are versatile and suitable for lightweight inference or preprocessing.<\/li>\n\n\n\n<li>GPUs excel at parallel tasks like model training and deep learning.<\/li>\n\n\n\n<li>TPUs (offered by Google) are optimized for TensorFlow workloads and deliver faster performance for specific ML tasks.<br>The decision involves trade-offs between performance, cost, and availability.<\/li>\n<\/ul>\n\n\n\n<p><strong>5. What challenges might arise when scaling AI workloads, and how can they be addressed?<\/strong><\/p>\n\n\n\n<p><strong>Sample Answer:<\/strong> Challenges include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Resource bottlenecks<\/strong> (compute, storage, network)<\/li>\n\n\n\n<li><strong>Model and data parallelism complexities<\/strong><\/li>\n\n\n\n<li><strong>Synchronization issues<\/strong> in distributed training<\/li>\n\n\n\n<li><strong>Cost escalation<\/strong><br>Solutions involve using orchestration tools like Kubernetes, distributed training libraries (Horovod), autoscaling clusters, and optimizing data pipelines with tools like Apache Spark or Dask.<\/li>\n<\/ul>\n\n\n\n<p><strong>6. How do AI-specific managed cloud services help in handling workloads?<\/strong><\/p>\n\n\n\n<p><strong>Sample Answer:<\/strong> Managed services like AWS SageMaker, Azure Machine Learning, and GCP Vertex AI simplify the AI lifecycle. They offer built-in tools for:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Data ingestion<\/li>\n\n\n\n<li>Model training and tuning (AutoML)<\/li>\n\n\n\n<li>Version control and reproducibility<\/li>\n\n\n\n<li>Inference endpoint deployment<br>These platforms reduce DevOps overhead and allow teams to focus on model development rather than infrastructure management.<\/li>\n<\/ul>\n\n\n\n<p><strong>7. What considerations go into deploying AI workloads at the edge versus the cloud?<\/strong><\/p>\n\n\n\n<p><strong>Sample Answer:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Edge deployment is chosen for low-latency, offline, or bandwidth-sensitive applications (e.g., IoT, autonomous vehicles).<\/li>\n\n\n\n<li>Cloud deployment offers scalability and centralized management.<br>Considerations include data privacy, real-time requirements, connectivity, power limitations, and update mechanisms. Tools like TensorFlow Lite and ONNX Runtime are useful for edge inference.<\/li>\n<\/ul>\n\n\n\n<p><strong>8.

How would you implement a question-answering solution on Azure using custom documents?<\/strong><\/p>\n\n\n\n<p>Sample Answer: I would use the Question Answering capability of Azure Language, formerly QnA Maker. I\u2019d upload or connect to my documents (PDFs, web pages, etc.), create a knowledge base, and Azure would extract Q&amp;A pairs. I can test and improve the responses in the portal and then publish it as an endpoint to integrate into a chatbot or web app.<\/p>\n\n\n\n<p><strong>7. What is key phrase extraction and when is it useful in NLP workflows?<\/strong><\/p>\n\n\n\n<p>Sample Answer: Key phrase extraction identifies the most important words or phrases in a document. It\u2019s useful for document summarization, search indexing, and understanding main topics in feedback or support tickets. Azure Language\u2019s Text Analytics API provides this functionality out of the box.<\/p>\n\n\n\n<p><strong>8. How does sentiment analysis work in Azure NLP services and what are the output components?<\/strong><\/p>\n\n\n\n<p>Sample Answer: Sentiment analysis returns an overall sentiment label (positive, negative, neutral, or mixed) for the text and for individual sentences. It also gives <strong>confidence scores<\/strong> for each sentiment, allowing for fine-tuned decision-making. The output is JSON-based, which makes integration with apps or dashboards straightforward.<\/p>\n\n\n\n<p><strong>9. What are the deployment options for custom NLP models trained using Azure Language?<\/strong><\/p>\n\n\n\n<p>Sample Answer: Custom NLP models can be hosted as REST APIs directly in Azure. For offline or edge use cases, Azure doesn\u2019t currently support downloading these models, so cloud deployment is the primary option. However, you can call these models from apps using Azure SDKs or Logic Apps for low-code automation.<\/p>\n\n\n\n<p><strong>10. Can you explain the limitations of Azure\u2019s prebuilt NLP models and when it\u2019s better to build custom models?<\/strong><\/p>\n\n\n\n<p>Sample Answer: Prebuilt models are limited to common languages and general tasks. They might not recognize domain-specific terms or provide high accuracy in specialized industries (e.g., legal, medical). In such cases, <strong>Custom Text Classification or Custom NER<\/strong> allows training on your labeled data to improve performance and relevance to your use case.<\/p>\n\n\n\n<h3 class=\"wp-block-heading has-text-align-center has-white-color has-black-background-color has-text-color has-background has-link-color wp-elements-eac198f7e4b5aee383b74cb099a410ab\"><strong>Topic 5 &#8211; Features of generative AI workloads on Azure <\/strong><\/h3>\n\n\n\n<p><strong>1.
