NEW QUESTION 1
You maintain an Azure Web App that runs in a container. The container is using a Dockerfile that is copied to numerous places and consumes a large amount of storage. You need to optimize the Dockerfile.
What should you do?

• A. Use multiple RUN instructions for cached operation.
• B. Configure the CU with a .dockerignore file.
• C. Minimize layers by concatenating all RUN instructions on one line.
• D. Minimize layers by grouping actions in as few RUN instructions as possible

Answer: D

Explanation: Minimize the number of layers.
Prior to Docker 17.05, and even more, prior to Docker 1.10, it was important to minimize the number of layers in your image.C
In Docker 1.10 and higher, only RUN, COPY, and ADD instructions create layers. References:

NEW QUESTION 2
You develop an IoT solution by using Node.js. The solution is ready to deploy to the production environment.
You must implement the device twin capabilities of Azure IoT Hub. You must register a sensor named Sensor00. The IoT Hub name is Hub01.
You need to register the endpoint with ContosoHub01 so that you can configure them from your solution. Which four 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.

Answer:

Explanation: Step 1: az extension add --name azure-cli-iot-ext
Run the following command in the command-line environment where you are using the Azure CLI to install the IoT extension:
az extension add --name azure-cli-iot-ext Step 2: az iot hub device-identity create
--hub-name {Hub01}
--device-id Sensor00
Create a new device identity called myDeviceId and retrieve the device connection string with these commands:
az iot hub device-identity create --device-id myDeviceId --hub-name {Your IoT Hub name}
az iot hub device-identity show-connection-string --device-id myDeviceId --hub-name {Your IoT Hub name}
-o table
Step 3: az iot hub device-identity show-connection-string
--hub-name {Hub01}
--device-id Sensor00
--output table Step 4:
Create the service app
In this section, you create a Node.js console app that adds location metadata to the device twin. npm install azure-iothub --save

Explanation: Topic 4, Proseware, Inc
Background
You are a developer for Proseware, Inc. You are developing an application that applies a set of governance policies for Proseware's internal services, external services, and applications. The application will also provide a shared library for common functionality.
Requirements 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.
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 Policy Lib 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.
Other
Anomaly detection service
You have an anomaly detection service that analyzes log information for anomalies. It is implemented as an Azure 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.
