Box 1: CreateJobBox 2: TaskSuccessTaskSuccess: Upload the file(s) only after the task process exits with an exit code of 0.Incorrect: TaskCompletion: Upload the file(s) after the task process exits, no matter what the exit code was.Box 3: TaskFailure TaskFailure:Upload the file(s) only after the task process exits with a nonzero exit code.Box 4: OutputFilesTo specify output files for a task, create a collection of OutputFile objects and assign it to the CloudTask.OutputFiles property when you create the task. References:https://docs.microsoft.com/en-us/dotnet/api/microsoft.azure.batch.protocol.models.outputfileuploadconditionhttps://docs.microsoft.com/en-us/azure/batch/batch-task-output-files

A Batch job is a logical grouping of one or more tasks. A job includes settings common to the tasks, such as priority and the pool to run tasks on. The app uses the BatchClient.JobOperations.CreateJob method to create a job on your pool.The Commit method submits the job to the Batch service. Initially the job has no tasks.{    CloudJob job = batchClient.JobOperations.CreateJob();    job.Id = JobId;    job.PoolInformation = new PoolInformation { PoolId = PoolId };    job.Commit();}...References:https://docs.microsoft.com/en-us/azure/batch/quick-run-dotnet

Windows Azure Web Sites (WAWS) offers 3 modes:  Standard, Free, and Shared.Standard mode carries an enterprise-grade SLA (Service Level Agreement) of 99.9% monthly, even for sites with just one instance. Standard mode runs on dedicated instances, making it different from the other ways to buy Windows Azure Web Sites. Incorrect Answers:B: Shared and Free modes do not offer the scaling flexibility of Standard, and they have some important limits.Shared mode, just as the name states, also uses shared Compute resources, and also has a CPU limit. So, while neither Free nor Shared is likely to be the best choice for your production environment due to these limits.

The function editor built into the Azure portal lets you update the function.json file and the code file for a function. The host.json file, which contains some runtime-specific configurations, is in the root folder of the function app.         References:https://docs.microsoft.com/en-us/azure/azure-functions/functions-reference#fileupdate

B: Incremental Sync: the first parameter to the pull operation is a query name that is used only on the client. If you use a non-null query name, the Azure Mobile SDK performs an incremental sync. Each time a pull operation returns a set of results, the latest updatedAt timestamp from that result set is stored in the SDK local system tables. Subsequent pull operations retrieve only records after that timestamp.E (not D): To use incremental sync, your server must return meaningful updatedAt values and must also support sorting by this field. However, since the SDK adds its own sort on the updatedAt field, you cannot use a pull query that has its own orderBy clause.References:https://docs.microsoft.com/en-us/azure/app-service-mobile/app-service-mobile-offline-data-sync

Box 1: PolicyRetryPolicy retry = Policy  .Handle<HttpRequestException>()  .Retry(3);The above example will create a retry policy which will retry up to three times if an action fails with an exception handled by the Policy.Box 2: WaitAndRetryAsync(3,i => TimeSpan.FromMilliseconds(100* Math.Pow(2,i-1)));A common retry strategy is exponential backoff: this allows for retries to be made initially quickly, but then at progressively longer intervals, to avoid hitting a subsystem with repeated frequent calls if the subsystem may be struggling.Example: Policy  .Handle<SomeExceptionType>()  .WaitAndRetry(3, retryAttempt =>     TimeSpan.FromSeconds(Math.Pow(2, retryAttempt))   );References:https://github.com/App-vNext/Polly/wiki/Retry

Retrieve all entities in a partition. The following code example specifies a filter for entities where 'Smith' is the partition key. This example prints the fields of each entity in the query results to the console. Construct the query operation for all customer entities where PartitionKey="Smith". TableQuery<CustomerEntity> query = new TableQuery<CustomerEntity>().Where(TableQuery.GenerateFilterCondition("PartitionKey", QueryComparisons.Equal, "Smith")); References:https://docs.microsoft.com/en-us/azure/cosmos-db/table-storage-how-to-use-dotnet

Scenario: Processing is performed by an Azure Function that uses version 2 of the Azure Function runtime. Once processing is completed, results are stored in Azure Blob Storage and an Azure SQL database. Then, an email summary is sent to the user with a link to the processing report. The link to the report must remain valid if the email is forwarded to another user.Create a stored access policy to manage signatures on a container's resources, and then generate the shared access signature on the container, setting the constraints directly on the signature. Code example: Add a method that generates the shared access signature for the container and returns the signature URI.static string GetContainerSasUri(CloudBlobContainer container) {     //Set the expiry time and permissions for the container.     //In this case no start time is specified, so the shared access signature becomes valid immediately.     SharedAccessBlobPolicy sasConstraints = new SharedAccessBlobPolicy();     sasConstraints.SharedAccessExpiryTime = DateTimeOffset.UtcNow.AddHours(24);     sasConstraints.Permissions = SharedAccessBlobPermissions.List | SharedAccessBlobPermissions.Write;     //Generate the shared access signature on the container, setting the constraints directly on the signature.     string sasContainerToken = container.GetSharedAccessSignature(sasConstraints);     //Return the URI string for the container, including the SAS token.     return container.Uri + sasContainerToken; } Incorrect Answers:C: Call GetSharedAccessSignature on the container, not on the blob.References:https://docs.microsoft.com/en-us/azure/storage/blobs/storage-dotnet-shared-access-signature-part-2

Scenario: The LabelMaker applications must be secured by using an AAD account that has full access to all namespaces of the Azure Kubernetes Service (AKS) cluster.Permissions can be granted within a namespace with a RoleBinding, or cluster-wide with a ClusterRoleBinding. References:https://kubernetes.io/docs/reference/access-authn-authz/rbac/

Enable Always Encrypted is correct, but only the WebAppIdentity service principal should be given access to the certificate. Scenario: Users’ SecurityPin must be stored in such a way that access to the database does not allow the viewing of SecurityPins. The web application is the only system that should have access to SecurityPins.
