   You have an app that analyzes images by using the Computer Vision API. You need to configure the app to provide an output for users who are vision impaired. The solution must provide the output in complete sentences. Which API call should you perform?

   • AreadInStreamAsync
   • BanalyzeImagesByDomainInStreamAsync
   • CtagImageInStreamAsync
   • DdescribeImageInStreamAsync

   Show answer

   Answer: D

   Explanation

   The API call you should perform to provide an output in complete sentences for users who are vision impaired is describeImageInStreamAsync. The describe feature of the Computer Vision API generates a human-readable sentence to describe the contents of an image. This is particularly useful for accessibility purposes, as it allows visually impaired users to understand what is in an image without needing to see it. The describe feature can also be customized to provide additional details or context, if desired. Therefore, the correct answer is D. describeImageInStreamAsync.

   • DPublish the raw survey data to a central location and provide the staff with access to the location.

   Show answer

   Answer: A

   Explanation

   To ensure that the AI solution meets the Microsoft responsible AI principles, you should: A. Add a human review and approval step before making decisions that affect the staff's financial situation. This option aligns with the responsible AI principle of fairness and accountability. By adding a human review and approval step, you ensure that the decisions affecting staff bonuses are reviewed by humans who can consider factors beyond just the sentiment analysis results. It adds an element of transparency, accountability, and fairness to the process, reducing the risk of biased or unfair decisions. (ChatGPT)

7. Question 47 · 328 in bank

   You have an app named App1 that uses an Azure Cognitive Services model to identify anomalies in a time series data stream. You need to run App1 in a location that has limited connectivity. The solution must minimize costs. What should you use to host the model?

   • AAzure Kubernetes Service (AKS)
   • BAzure Container Instances
   • Ca Kubernetes cluster hosted in an Azure Stack Hub integrated system
   • Dthe Docker Engine

   Show answer

   Answer: D

   Explanation

   To host your Azure Cognitive Services model in a location with limited connectivity while minimizing costs, you should use: D. the Docker Engine Here's why: Docker Engine allows you to run containerized applications locally without requiring a full orchestration platform. This can be particularly useful in environments with limited connectivity where you need to run applications in a more lightweight and cost-effective manner. Unlike Azure Kubernetes Service (AKS) or Azure Container Instances, which typically require internet connectivity to Azure for management and operation, Docker Engine can operate entirely offline once the container images are downloaded. Using a Kubernetes cluster hosted in an Azure Stack Hub integrated system (Option C) could work but would be significantly more complex and costly compared to simply using Docker Engine. Minimizing costs is a key consideration, and Docker Engine provides a straightforward, low-overhead solution compared to the other options.

   Answer: See figure below

   Explanation

   1. Create a private endpoint 2. Use Azure roles https://learn.microsoft.com/en-us/azure/search/service-create-private-endpoint#why-use-a-private-endpoint-for-secure-access Private Endpoints for Azure Cognitive Search allow a client on a virtual network to securely access data in a search index over a Private Link. The private endpoint uses an IP address from the virtual network address space for your search service. Network traffic between the client and the search service traverses over the virtual network and a private link on the Microsoft backbone network, eliminating exposure from the public internet. https://learn.microsoft.com/en-us/azure/search/search-security-rbac?tabs=config-svc-portal%2Croles-portal%2Ctest-portal%2Ccustom-role-portal%2Cdisable-keys-portal#grant-access-to-a-single-index In some scenarios, you may want to limit application's access to a single resource, such as an index. The portal doesn't currently support role assignments at this level of granularity, but it can be done with PowerShell or the Azure CLI.

    1. Provision on-premise k8 cluster that is isolated from Internet 2. Pull image from MCR 3. Run container and specify API key and endpoint URL of Cognitive Services Services https://learn.microsoft.com/en-us/azure/cognitive-services/containers/disconnected-containers Containers enable you to run Cognitive Services APIs in your own environment, and are great for your specific security and data governance requirements. Disconnected containers enable you to use several of these APIs disconnected from the internet. https://learn.microsoft.com/en-us/azure/cognitive-services/containers/disconnected-container-faq#how-do-i-download-the-disconnected-containers These containers are hosted on the Microsoft Container Registry and available for download on Microsoft Artifact Registry and Docker Hub. You won't be able to run the container if your Azure subscription has not been approved after completion of the request form.
