Case Study: 3
Mortgage Loan
Background
A company is developing a website that supports mortgage loan processing. You use the
Azure management portal to create a website. You initially configure the website to use the
Basic hosting plan. You register a custom domain for the website with a valid registrar.
Customers complete mortgage applications and upload supporting documents to the website.
A custom executable named FileProcessor.exe processes all of the information received. An
on premises server that runs Windows Server hosts the executable.
You create a virtual hard disk (VHD) image of the on premises server. You plan to use this
VHD to replace the on premises server with a new virtual machine (VM) that is hosted in
Azure.
Business Requirements
Business stakeholders have identified the following requirements for the mortgage loan
processing website:
• The website must provide a secure mortgage application process for the customer.
• Business users must validate new versions of the website before you publish them to
the production site. You must be able to revert to the previous version easily when issues
arise.
• The website must remain available to users while new features and bug fixes are
deployed.
• Network traffic must be monitored on all ports that the website uses.
Technical Requirements
General:
• You must develop the website by using Microsoft Visual Studio 2013.
• The website must be stateless. Subsequent requests from a user might or might not be
routed back to the website instance that the user initially connected to.
Security:
You must secure the custom domain and all subdomains by using SSL.
Storage:
• The custom executable must use native file system APIs to share data between
different parts of the website.
• The custom executable must continue to use a network file share to access files.
Monitoring:
The website must use port 6000 with UDP to submit information to another process. This
port must be actively monitored by using the same external port number.
Deployment:
• You must deploy the VM and the associated VHD. You will need to move this VM to
a different Azure subscription after deployment.
• You must establish a continuous deployment process that uses staged publishing.

• The custom domain must handle requests for multiple subdomains.
• The custom domain must use a www CNAME record that points to the domain’s @ A
record.
• The custom executable must run continuously and must be deployed as an Azure web
job named FileProcessor
• Application Request Routing (ARRJ affinity must be disabled for the website.
Solution Structure
The solution structure for the website is shown in the following exhibit.

You need to implement the web application deployment workflow.
In the Azure management portal, what should you do?

A.
Set the web hosting plan to Shared. Increase the instance count to 2. Publish the incremental updates to the
new instance.

B.
Set the web hosting plan to Standard. Use Windows PowerShell to create a new deployment slot to publish
the incremental updates. Swap the deployment slot after the business users have validated the updates.

C.
Set the web hosting plan to Standard. Create a new website to host the updated web application. Create a
Windows PowerShell script to move the contents of the new website to the production website location after
the business users have validated the updates.

D.
Download the publish profile. Use Visual Studio to import the publish profile. Deploy the web application by
using the Visual Studio Publish Web wizard after the business users have validated the updates.
