Demo Questions
Question 1
You need to configure Azure CDN for the Shipping web site.
Which configuration options should you use? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Correct answer: To work with this question, an Exam Simulator is required.
Explanation:
Scenario: Shipping websiteUse Azure Content Delivery Network (CDN) and ensure maximum performance for dynamic content while minimizing latency and costs. Tier: StandardProfile: AkamaiOptimization: Dynamic site accelerationDynamic site acceleration (DSA) is available for Azure CDN Standard from Akamai, Azure CDN Standard from Verizon, and Azure CDN Premium from Verizon profiles. DSA includes various techniques that benefit the latency and performance of dynamic content. Techniques include route and network optimization, TCP optimization, and more. You can use this optimization to accelerate a web app that includes numerous responses that aren't cacheable. Examples are search results, checkout transactions, or real-time data. You can continue to use core Azure CDN caching capabilities for static data. Reference:https://docs.microsoft.com/en-us/azure/cdn/cdn-optimization-overview Scenario: Shipping website

Correct answer: To work with this question, an Exam Simulator is required.
Explanation:
Box 1: Azure BackupThe VM is critical and has not been backed up in the past. The VM must enable a quick restore from a 7-day snapshot to include in-place restore of disks in case of failure. In-Place restore of disks in IaaS VMs is a feature of Azure Backup. Performance: Accelerated NetworkingScenario: The VM shows high network latency, jitter, and high CPU utilization. Box 2: Accelerated networkingThe VM shows high network latency, jitter, and high CPU utilization. Accelerated networking enables single root I/O virtualization (SR-IOV) to a VM, greatly improving its networking performance. This high-performance path bypasses the host from the datapath, reducing latency, jitter, and CPU utilization, for use with the most demanding network workloads on supported VM types.

Question 3
You need to correct the RequestUserApproval Function app error.
What should you do?
- Update line RA13 to use the async keyword and return an HttpRequest object value.
- Configure the Function app to use an App Service hosting plan. Enable the Always On setting of the hosting plan.
- Update the function to be stateful by using Durable Functions to process the request payload.
- Update the functionTimeout property of the host.json project file to 15 minutes.
Correct answer: C
Explanation:
Async operation tracking The HTTP response mentioned previously is designed to help implement long-running HTTP async APIs with Durable Functions. This pattern is sometimes referred to as the polling consumer pattern. Both the client and server implementations of this pattern are built into the Durable Functions HTTP APIs. Function app You perform local testing for the RequestUserApproval function. The following error message displays: 'Timeout value of 00:10:00 exceeded by function: RequestUserApproval' The same error message displays when you test the function in an Azure development environment when you run the following Kusto query: FunctionAppLogs | where FunctionName = = "RequestUserApproval" Reference: https://docs.microsoft.com/en-us/azure/azure-functions/durable/durable-functions-http-features Async operation tracking
