You plan to create a Docker image that runs an ASP.NET Core application named ContosoApp. You have a setup script named setupScript.ps1 and a series of application files including ContosoApp.dll.
You need to create a Dockerfile document that meets the following requirements:
* Call setupScripts.ps1 when the container is built.
* Run ContosoApp.dll when the container starts.
The Dockerfile document must be created in the same folder where ContosoApp.dll and setupScript.ps1 are stored.
Which five commands should you use to develop the solution? To answer, move the appropriate commands from the list of commands to the answer area and arrange them in the correct order.

Correct Answer:

Explanation

Box 1: CMD [..]
Cmd starts a new instance of the command interpreter, Cmd.exe.
Syntax: CMD <string>
Specifies the command you want to carry out.
Box 2: FROM microsoft/aspnetcore-build:latest
Box 3: WORKDIR /apps/ContosoApp
Bxo 4: COPY ./ .
Box 5: RUN powershell ./setupScript.ps1

You develop an app that allows users to upload photos and videos to Azure storage. The app uses a storage REST API call to upload the media to a blob storage account named Account1. You have blob storage containers named Container1 and Container2.
Uploading of videos occurs on an irregular basis.
You need to copy specific blobs from Container1 to Container2 when a new video is uploaded.
What should you do?

• A.Copy blobs to Container2 by using the operation of the Blob Service REST API
• B.Create an Event Grid topic that uses the Start-AzureStorageBlobCopy cmdlet
• C.Use AzCopy with the Snapshot switch to copy blobs to Container2
• D.Download the blob to a virtual machine and then upload the blob to Container2

You are developing an Azure Web App. You configure TLS mutual authentication for the web app.
You need to validate the client certificate in the web app. To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.

Correct Answer:

Explanation

Accessing the client certificate from App Service.
If you are using ASP.NET and configure your app to use client certificate authentication, the certificate will be available through the HttpRequest.ClientCertificate property. For other application stacks, the client cert will be available in your app through a base64 encoded value in the "X-ARR-ClientCert" request header.
Your application can create a certificate from this value and then use it for authentication and authorization purposes in your application.

Case Study 7
Policy service
You develop and deploy a stateful ASP.NET Core 2.1 web application named Policy service to an Azure App Service Web App. The application reacts to events from Azure Event Grid and performs policy actions based on those events.
The application must include the Event Grid Event ID field in all Application Insights telemetry.
Policy service must use Application Insights to automatically scale with the number of policy actions that it is performing.
Other
Anomaly detection service
You have an anomaly detection service that analyzes log infrmation for anomalies. It is implemented as an Azure Machine Learning model. The model is deployed as a web service.
If an anomaly is detected, an Azure Function that emails administrators is called by using an HTTP WebHook.
Health monitoring
All web applications and services have health monitoring at the /health service endpoint.
Issues
Policy loss
When you deploy Policy service, policies may not be applied if they were in the process of being applied during the deployment.
Performance issue
When under heavy load, the anomaly detection service undergoes slowdowns and rejects connections.
Notification latency
Users report that anomaly detection emails can sometimes arrive several minutes after an anomaly is detected.
Policies
Log policy
All Azure App Service Web Apps must write logs to Azure Blob storage. All log files should be saved to a container named logdrop. Logs must remain in the container for 15 days.
Authentication events
Authentication events are used to monitor users signing in and signing out. All authentication events must be processed by Policy service. Sign outs must be processed as quickly as possible.
PolicyLib
You have a shared library named PolicyLib that contains functionality common to all ASP.NET Core web services and applications. The PolicyLib library must:
* Exclude non-user actions from Application Insights telemetry.
* Provide methods that allow a web service to scale itself.
* Ensure that scaling actions do not disrupt application usage.
Relevant portions of the app files are shown below. Line numbers are included for reference only and include a two-character prefix that denotes the specific file to which they belong.

Uploading of videos occurs on an irregular basis.
You need to copy specific blobs from Container1 to Container2 in real time when specific requirements are met, excluding backup blob copies.
What should you do?

• A.Download the blob to a virtual machine and then upload the blob to Container2.
• B.Run the Azure PowerShell command Start-AzureStorageBlobCopy.
• C.Copy blobs to Container2 by using the Put Blob operation of the Blob Service REST API.
• D.Use AzCopy with the Snapshot switch blobs to Container2.
