NEW QUESTION 1
A company is migrating an existing on-premises third-party website to Azure. The website is stateless. The company does not have access to the source code for the website. They do have the original installer. The number of visitors at the website vanes throughout the year.
The on-premises infrastructure was resized to accommodate peaks but the extra capacity was not used. You need to implement a virtual machine scale set instance.
What should you do?

• A. Use only default diagnostics metrics to trigger autoscaling.
• B. Create 100 autoscale settings per resource.
• C. Scale out by one instance when the average CPU usage of one of the instances is over 80 percent
• D. Use Azure Monitor to create autoscale settings using custom metrics

Answer: D

Explanation: Azure Monitor autoscaling allows you to scale the number of running instances up or down, based on telemetry data (metrics).

NEW QUESTION 3
Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution. Determine whether the solution meets the stated goals.
You develop an entertainment application where users can buy and trade virtual real estate. The application must scale to support thousands of users.
The current architecture includes five Azure Virtual Machines (VM) that connect to an Azure SQL Database for account information and Azure Table Storage for backend services. A user interacts with these components in the cloud at any given time
- Routing Service – Routes a request to the appropriate service and must not persist data across sessions
- Account Service – Stores and manages all account information and authentication and requires data to persist across sessions.
- User Service – Stores and manages all user information and requires data to persist across sessions.
- Housing Network Service – Stores and manages the current real-estate economy and requires data to persist across sessions.
- Trade Service – Stores and manages virtual trade between accounts and requires data to persist across sessions.
Due to volatile user traffic, a microservices solution is selected for scale agility.
You need to migrate to a distributed microservices solution on Azure Service Fabric.
Solution: Create a Service Fabric Cluster with a stateful Reliable Service for Routing Service. Deploy a Guest Executable to Service Fabric for each component.
Does the solution meet the goal?

• A. YES
• B. NO

Answer: B

Explanation: We should use stateful services when we want data to persist, and stateless service when data must not persist. References:

NEW QUESTION 5
A construction company creates three-dimensional models from photographs and design diagrams of buildings. The company plans to store high-resolution photographs and blueprint files in Azure Blob Storage. The files are currently stored in the construction company’s office.
You are developing a tool to connect to Azure Storage, create container, and then upload the files. The tool must remain responsive to the end user while it is running and performing remote I/O operations. It must also wait for methods to complete before continuing.
You need to complete the configuration.
How should you complete the code? To answer, select the appropriate options in the answer area. NOTE: Each correct solution is worth one point.

Answer:

Explanation: Box 1: ProcessAsync();
Box 2: await cloudBlobContainer.CreatAsync();
If you specify that a method is an async method by using the async modifier, you enable the following two capabilities.
The marked async method can use await to designate suspension points. The await operator tells the compiler that the async method can't continue past that point until the awaited asynchronous process is complete. In the meantime, control returns to the caller of the async method.
The suspension of an async method at an await expression doesn't constitute an exit from the method, and finally blocks don’t run.
The marked async method can itself be awaited by methods that call it. References:

You need to simultaneously transfer the large files as efficiently as possible.
Solution: Write a C# application that uses the Azure .NET API method CloudFile.StartCopyAsync to transfer files to the destination container.
Does the solution meet the goal?

• A. Yes
• B. No

You are creating an app that uses Event Grid to connect with other services. Your app's event data will be sent to a servefless function that checks compliance. This function is maintained by your company.
You write a new event subscription at the scope of your resource. The event must be invalidated after 3 specific period of time. You need to configure Event Grid to ensure security.
What should you implement? To answer, select the appropriate options in [he answer area. NOTE: Each correct selection is worth one point

Answer:

Explanation: Box 1: SAS tokens
Custom topics use either Shared Access Signature (SAS) or key authentication. Microsoft recommends SAS, but key authentication provides simple programming, and is compatible with many existing webhook publishers.
In this case we need the expiration time provided by SAS tokens. Box 2: ValidationCode handshake
Event Grid supports two ways of validating the subscription: ValidationCode handshake (programmatic) and ValidationURL handshake (manual).
If you control the source code for your endpoint, this method is recommended.
