Which type of storage should you use to store the images?
You are designing an Azure application that processes graphical image files. The graphical Images are
processed in batches by remote applications that run on multiple servers.
You have the following requirements:
The application must remain operational during batch-processing operations.
Users must be able to roll back each image to a previous version.
You need to ensure that each remote application has exclusive access to an image while the application
processes the image. Which type of storage should you use to store the images?
Which change always requires downtime?
You are planning an upgrade strategy for an existing Azure application. Multiple instances of the application runin Azure. The management team is concerned about application downtime, due to a business service level
agreement (SLA).
You are evaluating which change in your environment will require downtime.
You need to identify the changes to the environment that will force downtime.
Which change always requires downtime?
What should you recommend?
You are evaluating an Azure application. The application includes the following elements:
A web role that provides the ASP.NET user interface and business logic
A single SQL database that contains all application data
Each webpage must receive data from the business logic layer before returning results to the client. Traffic has
increased significantly. The business logic is causing high CPU usage.
You need to recommend an approach for scaling the application.
What should you recommend?
Which approach should you recommend?
You are designing an Azure Web App that will use one worker role. The Web App does not use SQL
Database.
You have the following requirements:
Maximize throughput and system resource availability
Minimize downtime during scaling
You need to recommend an approach for scaling the application.
Which approach should you recommend?
Where should you create the files?
You are designing an Azure application that will use a worker role. The worker role will create temporary files.
You need to minimize storage transaction charges.
Where should you create the files?
What should you recommend?
You are designing an Azure application. The application includes two web roles and three instances of a worker
role. The web roles send requests to the worker role by using one or more Azure Queues.
You need to recommend a queue design for sending requests to the worker role.
What should you recommend?
What should you recommend?
You design an Azure application that processes images. The maximum size of an image is 10 MB. The
application includes a web role that allows users to upload images and a worker role with multiple instances
that processes the images. The web role communicates with the worker role by using an Azure Queue service.
You need to recommend an approach for storing images that minimizes storage transactions.
What should you recommend?
Which three actions must be performed in sequence?

Testlet 1
Background:
You are the new cloud architect for Fourth Coffee. The company hosts an on-premises ASP.NET MVC web
application to allow online purchases and to support their retail store operations.
The new chief information officer (CIO) has announced several initiatives for the new year, including a new
mobile application, online training for retail store employees, and moving the current web application and other
services to the cloud.
The marketing team hopes to see an increase in the up-time for the web application. The team would also like
to allow users to use social logins in addition to the current username and password system.
Fourth Coffee has chosen Microsoft Azure to support their initiatives.
Current environment
In the Azure portal, you create an Azure Mobile App for the API. You create a Service Bus queue in Azure and
install the Azure Storage SDK for Node.js.
Problem statements
The mobile team attempts to use continuous deployment with the Azure App Service and new API project. They
receive the following error message: “Unable to access http://fourthcoffeeapi.azurewebsites.net/: Failed to
connect to https://fourthcoffeeapi.scm.azurewebsites.net/”
Business requirements
Web Application
You must increase up-time for the application.
The application must support additional regions and languages.
Marketing must be able to validate the web application before updates to the application are published to the
production environment.
Mobile
The marketing team must be able to send frequent and timely updates to specific users and devices
including Apple iPad, iPhone, Android, Windows, and Windows Phone devices.
Users must be able to use their social accounts to sign in to the application. You must support LinkedIn,
Facebook and Google logons.
The application must remain responsive, even during peak periods.
Training
Video streaming content must be made available and streamed to employee’s browsers. Training content must
only include on-demand streaming. There will be no live content.
Technical requirements
Web Application
You must update the deployment process to support cloud deployments.
All data must be formatted as JSON during transport.
You must implement Team Foundation Version Control (TFVC) as the version control system for the web
application.
Incoming messages to the API must be persisted to queue storage to ensure they are delivered and
processed. You must restrict the size of messages between the mobile app and the API to no more than 5
gigabytes (GB).
The web application must use geo-redundant replication.
Mobile
You must use Node.js as a technology platform. You must support all mobile initiatives when possible.
You must implement Git as the version control system for the mobile app.
You must develop a REST API by using Node.js Express, and MongoDB. You must use the Mobile Apps
feature of the Azure App Service to host the API in Standard mode.
You must implement the following Push Notification Services by using Azure Media Services:
– Apple Push Notification Service (APNS) for iPad and iPhone devices- Google Cloud Messaging service (GCM) for Android devices
– Windows Notification Service (WNS) for Windows devices
– Microsoft Push Notification Service (MPNS) for Windows Phone devices
Security and disaster Recovery
You must integrate the on-premises Active Directory Domain Services with Azure Active Directory (Azure
AD).
You must implement the latest federated identity standards to provide authentication and authorization to
applications.
You must implement Multi-Factor Authentication.
The web application and the API must be able to recover from a disaster.
Scaling
The web application and API must auto-scale according to the following rules:
Scale up by one instance if CPU is above 70%.
Scale down by one instance if CPU is below 50%.
Training
Streaming must include Content Delivery Network (CDN) capabilities to support global locations.
Content must be encrypted and protected by using AES and PlayReady.
Streaming must include one gigabit (GB) per second of dedicated egress capacity.
All videos must use adaptive bitrate MP4 encoded content and include a streaming manifest file (.ism).
You must support the following streaming formats for video files: MPEG DASH, HLS, Smooth Streaming,
HDS. You must not to re-encode the content.
