   Answer: See figure below

   Explanation

   ORDER BY queries on multiple properties: The composite index also supports an ORDER BY clause with the opposite order on all paths. So I think it's about reversed index to the query. Answer should be 'ascending'. You cannot support ASC (default), DESC query with DESC, DESC index.

   Explanation

   Box 1: Helm - To create the ingress controller, use Helm to install nginx-ingress. Box 2: kubectl - To find the cluster IP address of a Kubernetes pod, use the kubectl get pod command on your local machine, with the option -o wide . Box 3: Ingress Controller - An ingress controller is a piece of software that provides reverse proxy, configurable traffic routing, and TLS termination for Kubernetes services. Kubernetes ingress resources are used to configure the ingress rules and routes for individual Kubernetes services. Incorrect Answers: Virtual Kubelet: Virtual Kubelet is an open-source Kubernetes kubelet implementation that masquerades as a kubelet. This allows Kubernetes nodes to be backed by Virtual Kubelet providers such as serverless cloud container platforms. CoreDNS: CoreDNS is a flexible, extensible DNS server that can serve as the Kubernetes cluster DNS. Like Kubernetes, the CoreDNS project is hosted by the CNCF.

8. Question 188 · 462 in bank

   DRAG DROP - Your company has several websites that use a company logo image. You use Azure Content Delivery Network (CDN) to store the static image. You need to determine the correct process of how the CDN and the Point of Presence (POP) server will distribute the image and list the items in the correct order. In which order do the actions occur?

   Answer: See figure below

   Explanation

   Step 1: A user requests the image.. A user requests a file (also called an asset) by using a URL with a special domain name, such as <endpoint name>.azureedge.net. This name can be an endpoint hostname or a custom domain. The DNS routes the request to the best performing POP location, which is usually the POP that is geographically closest to the user. Step 2: If no edge servers in the POP have the.. If no edge servers in the POP have the file in their cache, the POP requests the file from the origin server. The origin server can be an Azure Web App, Azure Cloud Service, Azure Storage account, or any publicly accessible web server. Step 3: The origin server returns the.. The origin server returns the file to an edge server in the POP. An edge server in the POP caches the file and returns the file to the original requestor (Alice). The file remains cached on the edge server in the POP until the time-to-live (TTL) specified by its HTTP headers expires. If the origin server didn't specify a TTL, the default TTL is seven days. Step 4: Subsequent requests for.. Additional users can then request the same file by using the same URL that the original user used, and can also be directed to the same POP. If the TTL for the file hasn't expired, the POP edge server returns the file directly from the cache. This process results in a faster, more responsive user experience.

9. Question 189 · 462 in bank

   Select 2

   You are developing an Azure Cosmos DB solution by using the Azure Cosmos DB SQL API. The data includes millions of documents. Each document may contain hundreds of properties. The properties of the documents do not contain distinct values for partitioning. Azure Cosmos DB must scale individual containers in the database to meet the performance needs of the application by spreading the workload evenly across all partitions over time. You need to select a partition key. Which two partition keys can you use? Each correct answer presents a complete solution. NOTE: Each correct selection is worth one point.

   • Aa single property value that does not appear frequently in the documents
   • Ba value containing the collection name
   • Ca single property value that appears frequently in the documents
   • Da concatenation of multiple property values with a random suffix appended
   • Ea hash suffix appended to a property value

   Show answer

   Answer: DE

   Explanation

   If no property in the document data will have unique values, you need to make one. This is called a synthetic partition key. These sorts of keys are made by adding a unique suffix at the end of some property. One other way is to create a property that will have the hashed data + a random suffix. The objective is to have a property that is random enough so that you can rely on it to be your key.

    Explanation

    Box 1: Yes - The createDatabaseIfNotExistsAsync method checks if a database exists, and if it doesn't, create it. The Database.CreateContainerAsync method creates a container as an asynchronous operation in the Azure Cosmos service. Box 2: Yes - The CosmosContainer.CreateItemAsync method creates an item as an asynchronous operation in the Azure Cosmos service.
