You manage API management policies in Azure.
You attempt to add a policy that is marked as unavailable.
You need to ensure that you can add the desired policy.
What should you do?

You deploy a Virtual Machine Scale Set (VMSS) named CorpWebVMSS to Azure by using Azure PowerShell and set the instance count to 1. The VMSS includes a storage account, load balancer, public IP address. and six Standard_A1 Windows virtual machines (VMs) that run Internet Information Services (IIS). All components are deployed to a resource group named CorpWebRG.
You must increase the instance count to support the increased load on IIS.
You need to manually scale out the number of VMs in the scale set to 5.
Solution: You run the following Azure PowerShell commands:
$vmss = Get-AzureRmVmss -ResourceGroupName CorpWebRG –VMScalesSetName CorpWebVMSS
$vmss.Sku.Capacity = 5
Update-AzureRmVmss -ResourceGroupName CorpWebRG -Name CorpWebVMSS -VirtualMachineScaleSet
$vmss

HOTSPOT
You are developing a multitenant application that uses Azure Search services. You have the following tenants:

You must minimize costs associated with implementing any solution. The cost model must be predictable.
You need to design the search experience for the application.
Which Azure Search pattern should you use for each tenant? To answer, select the appropriate options in the answer area.

CASE STUDY
Background:
You are developer for Fabrikam, a company that specializes in payment processing. Fabrikam is developing a solution to process payments for various events, such as music concerts. You develop an ASP.NET MVC website that is hosted in Azure to support an upcoming music concert. The music concert is expected to generate a large volume of ticket sales in a short amount of time.
The website uploads information to an Azure storage queue. A worker role in Azure retrieves information from the queue and generates the concert tickets in a PDF file format after the financial transaction is approved.You observe a delay between the time the website adds a message to a queue and the time it becomes available to read from the queue. After examining the queue, you determine that no queue messages have a
DequeueCount value greater than zero. The website does not throw any errors.
Business Requirements
Payments:
The music concert website must be able to submit event payment information for processing. The website must remain responsive while submitting payment information. Customers must be able to add notes about their orders to a free-form control on the website. These notes must be submitted with the payment when the customer submits an order.
Customers often enter notes that exceed 7 KB in size.
Technical Requirements
Payment Submission and Processing:
Event payment information must be sent from the website to a Windows Communication Foundation (WCF) service worker role. The worker role must submit the information to the payment processor in JSON format.
Payment Processing
You have the following payment processing requirements:
If the number of messages in a queue goes above or below a specified threshold, worker role instances must be created or deleted as needed. This process must be completed by using the least amount of effort.
It must be easy to reconfigure role instance thresholds.
Payments must be retrieved from the queue in the maximum batch sizes that are allowed by the queue and pulled from the queue for 5 minutes.
The payment queue must not be re-created when processing payments.
During single Payment processing, the number of tickets available for an event must be updated. The update operation must be retried for 30 seconds or 5 retry attempts, whichever occurs first. Each retry should pause for at least two seconds and for one second longer than the previous attempt. If the update fails, the payment should be placed in the poison queue.
Storage:
You have the following storage requirements:
Payment information must be stored by using Azure Queue storage. Connection to the Azure storage account has been established in a configured setting namedStorageConnectionString, which is configured for the web and worker roles.
A payment processing queue and a poison payment queue must be used when processing payments.
Azure Queue message content must be XML-safe and UTF-8 encoded.
An Azure storage account must be established for diagnostic information in a configured setting namedDiagnosticsStorageConnectionString, which is configured for both the web and worker roles.
Security and Monitoring
Security
The web role must be secured by using HTTPS.
Monitoring
You must collect diagnostic data for both the web and worker roles by using the Diagnostics module.
Diagnostics configuration changes must not require the code of the roles to be rebuilt. The diagnostic data is used for debugging and troubleshooting, measuring performance, monitoring resource usage, traffic analysis and capacity planning, and auditing.
Performance testing must evaluate the roles under normal and stress conditions without incurring changes for running Azure. Memory allocation, function time, and multithreading concurrency issues must be evaluated.
Deployment:
You purchase a custom domain name fabrikamfunding.com to host the website, web role, and worker roles.
You must deploy an HTTPS certificate with the web role, and you must update associated configuration files accordingly.
Web role and worker role instance sizes must be specified as Medium. You must deploy one web role instancenamed FabrikamFundingPaymentGenerator, and worker role instances named
FabrikamFundingPaymentProcessor.
Application Structure:
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 while they belong.

The SendMessageAsync method of the QueueManager class occasionally throws errors.
You need to correct the errors.
