Explanation AcrPush Contributor The Azure Container Registry service supports a set of built-in Azure roles that provide different levels of permissions to an Azure container registry. Use Azure role-based access control (Azure RBAC) to assign specific permissions to users, service principals, or other identities that need to interact with a registry.

You have uploaded a certificate to an Azure Web App named Application1. You need to access the certificate from the app code of Application1. What should you configure?

Explanation Add an app setting (WEBSITE_LOAD_CERTIFICATES) to the Application1 configuration In your application code, you can access the public or private certificates you add to App Service. Your app code may act as a client and access an external service that requires certificate authentication, or it may need to perform cryptographic tasks. The WEBSITE_LOAD_CERTIFICATES app setting makes the specified certificates accessible to your Windows hosted app in the Windows certificate store, https://docs.microsoft.com/en-us/azure/app-service/configure-ssl-certificate-in-code

You are developing an application that executes short lived processes on a schedule. You need to recommend a service that keeps costs and admin activities minimal. What should you recommend?

Explanation Azure Functions. Azure Functions allows you to run small pieces of code (called "functions") without worrying about application infrastructure. A function is "triggered" by a specific type of event. Supported triggers include responding to changes in data, responding to messages, running on a schedule, or as the result of an HTTP request. https://docs.microsoft.com/en-us/azure/azure-functions/functions-overview

You have an Azure Storage account named StorageAccount1. You plan to store data that is rarely accessed in StorageAccount1 for several years. You must ensure that the data in Blob storage is always available for immediate access. The solution must minimize storage costs. Which storage tier should you use?

Explanation Cool. The cool access tier has lower storage costs and higher access costs compared to hot storage. This tier is intended for data that will remain in the cool tier for at least 30 days. Example usage scenarios for the cool access tier include: Short-term backup and disaster recovery datasets. Older media content not viewed frequently anymore but is expected to be available immediately when accessed. Large data sets that need to be stored cost effectively while more data is being gathered for future processing. (For example, long-term storage of scientific data, raw telemetry data from a manufacturing facility) https://docs.microsoft.com/en-us/azure/storage/blobs/storage-blob-storage-tiers?tabs=azure-portal

You are developing a web service that should prevent anonymous usage and use OpenID connect for authentication. You need to implement an API Management policy for the web service. Which policy should you use?

Explanation Correct Answers: Validate-jwt - The requirement from the question to validate requests using API management policy. You can use the Validate JWT policy to pre-authorize requests in API Management, by validating the access tokens of each incoming request. If a request does not have a valid token, API Management blocks it. https://docs.microsoft.com/en-us/azure/api-management/api-management-howto-protect-backend-with-aad#configure-a-jwt-validation-policy-to-pre-authorize-requests

You have a mobile app that connects to the Azure App Service API to upload and extract metadata from the documents. The process of extracting metadata is CPU-intensive operation. Usage of the mobile app has increased drastically. You need to modify the App Service API to use a queue. The revised solution must scale and handle spikes in the number of requests. You need to recommend a solution keeping costs minimal between request spikes. What should you recommend?

Explanation Create a queue triggered Azure function to process the queue and move extraction logic to the Azure function.

You developing an application named Application1 that uses Azure Blob storage named Storage1. For audit purposes, Application1 must read the transaction logs of all changes that occur to the blobs and blob metadata in Storage1. The changes must be in the order in which they occurred. You need to process the logs asynchronously and should include only create, update, delete and copy operations. What should you do to implement audit requirement?

Explanation Enable Change feed on the storage account and process all changes for available events. Change feed provides transaction logs of all the changes that occur to the blobs and the blob metadata in your storage account. The change feed provides ordered, guaranteed, durable, immutable, read-only log of these changes. Client applications can read these logs at any time, either in streaming or in batch mode. https://docs.microsoft.com/en-us/azure/storage/blobs/storage-blob-change-feed?tabs=azure-portal

You are developer for a company named Company1. Company1 has an application that uses Azure Cosmos DB configured with Azure Cosmos DB SQL API. The database contains millions of documents without distinct values for partitioning. You need to implement a scaling strategy for the database to scale individual containers. The database must meet the performance requirements 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?

Explanation The goal is to distribute your data and workload evenly across the items associated with these partition key values. If such a property doesn't exist in your data, you can construct a synthetic partition key. You can form a partition key by concatenating multiple property values into a single artificial partition Key property. These keys are referred to as synthetic keys. Another possible strategy to distribute the workload more evenly is to append a random number at the end of the partition key value. When you distribute items in this way, you can perform parallel write operations across partitions. https://docs.microsoft.com/en-us/azure/cosmos-db/synthetic-partition-keys

You have a service principal named ServicePrincipal1. You need to provide read access to ServicePrincipal1 to read the resources in a resource group named ResourceGroup1. Select the actions that should you perform in the correct sequence?

Explanation To access resources in your subscription, you must assign a role to the application. Permissions are inherited to lower levels of scope. For example, adding an application to the Reader role for a resource group means it can read the resource group and any resources it contains. To assign a role at the resource group scope, search for and select "Resource Groups", select the particular resource group, select Access Control (IAM), Select Add -> Add role assignment, Select the role you wish to add. https://docs.microsoft.com/en-us/azure/active-directory/develop/howto-create-service-principal-portal#assign-a-role-to-the-application

You are developing a web application that will be hosted in an Azure Web App. The users for web application will be authenticated by using their Azure Active Directory (Azure AD). Users will be assigned with one of the following permission levels: admin, normal, and reader. A user's Azure AD group membership must be used to determine the permission level. To achieve the above requirement, you have created a new Azure AD application and configured the value of the groupMembershipClaims option to All in the application's manifest. In the web application, you use the value of the groups claim from the JWT for the user to determine permissions. Did you achieve the requirement?

Explanation Yes To configure group's optional claims through the application manifest, use groupMembershipClaims. The valid values for groupMembershipClaims are: "All" (this option includes SecurityGroup, DirectoryRole, and DistributionList) "SecurityGroup" "DirectoryRole" "ApplicationGroup" (this option includes only groups that are assigned to the application) https://docs.microsoft.com/en-us/azure/active-directory/develop/active-directory-optional-claims

You define an API Policy object by using the below XML markup: <set-variable name="bodySize" value="@(context.Request.Headers["Content-Length"][0])" /> <choose> <when condition="@(int.Parse(context.Variables.GetValueOrDefault<string>("bodySize"))<400000)"> </when> <otherwise> <rewrite-uri template="/put"/> <set-backend-service base-url="http://preparationlabs.com/api/8.1/"/> </otherwise> </choose> Select Yes if the below statement is true. Otherwise, select No 1. The XML Segment is part of the <inbound> section of the API policy. 2. An error will be thrown if the body size is >265K 3. The policy will retain the higher version if the request is http://preparationlabs.com/api/8.2/

Explanation Yes, No, No 1. The set-backend-service policy is used to redirect incoming requests. Therefore, this policy definition is part of inbound section https://docs.microsoft.com/en-us/azure/api-management/api-management-advanced-policies#choose 2. The condition on body size 400K. So, you will not get an error. 3. There are conditions defined in the policy based on the body size. So, it will not retain the higher version always. The default/otherwise is version 8.1

You have a new Azure subscription. You are developing an internal website for employees to view sensitive data. The website uses Azure Active Directory (Azure AD) for authentication. You need to implement multifactor authentication for the website. Which two actions should you perform?

Explanation - In Azure AD, create a new conditional access policy - Upgrade to Azure AD Premium Correct Answer(s): Multi-factor authentication (MFA) is a process in which a user is prompted for additional forms of identification during a sign-in event. For example, the prompt could be to enter a code on their cellphone or to provide a fingerprint scan. When you require a second form of identification, security is increased because this additional factor isn't easy for an attacker to obtain or duplicate. Azure AD Multi-Factor Authentication and Conditional Access policies give you the flexibility to require MFA from users for specific sign-in events. Prerequisite to configure conditional access policy is at least an Azure AD Premium P1 license. https://docs.microsoft.com/en-us/azure/active-directory/authentication/tutorial-enable-azure-mfa

You use Application Insights telemetry to monitor the app. You need to configure a test for the web app. You must test the app to ensure that the app is available and responsive from various points around the world and at regular intervals. If the app is not responding, you must send an alert to support staff. Which two test types should you use?

Explanation multi-step web URL ping After you've deployed your web app/website, you can set up recurring tests to monitor availability and responsiveness. Azure Application Insights sends web requests to your application at regular intervals from points around the world. It can alert you if your application isn't responding, or if it responds too slowly. Types of availability tests: There are three types of availability tests: URL ping test: a simple test that you can create in the Azure portal. Multi-step web test: A recording of a sequence of web requests, which can be played back to test more complex scenarios. Multi-step web tests are created in Visual Studio Enterprise and uploaded to the portal for execution. Custom Track Availability Tests: If you decide to create a custom application to run availability tests, the TrackAvailability() method can be used to send the results to Application Insights.
