You are planning an upgrade strategy for an existing Azure application. Multiple instances of the
application run in 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?

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?

You are designing an Azure application that stores data.
You have the following requirements:
The data storage system must support storing more than 500 GB of data.
Data retrieval must be possible from a large number of parallel threads.
Threads must not block each other.
You need to recommend an approach for storing data.

HOTSPOT
You have an Azure website that runs on several instances. You have a WebJob that provides
additional functionality to the website.
The WebJob must run on all instances of the website.
You need to ensure that the WebJob runs even when the website is idle for long periods of time.
How should you create and configure the WebJob object? To answer, select the appropriate options
in the answer area.

You are designing an Azure web application that includes many static content files.
The application is accessed from locations all over the world by using a custom domain name.
You need to recommend an approach for providing access to the static content with the least
amount of latency.
Which two actions should you recommend? Each correct answer presents part of the solution.

An application currently resides on an on-premises virtual machine that has 2 CPU cores, 4 GB of
RAM, 20 GB of hard disk space, and a 10 megabit/second network connection.
You plan to migrate the application to Azure. You have the following requirements:
You must not make changes to the application.
You must minimize the costs for hosting the application.
You need to recommend the appropriate virtual machine instance type.
Which virtual machine tier should you recommend?

You are designing an Azure development environment. Team members learn Azure development
techniques by training in the development environment.
The development environment must auto scale and load balance additional virtual machine (VM)
instances.
You need to recommend the most cost-effective compute-instance size that allows team members
to work with Azure in the development environment.

You have business services that run on an on-premises mainframe server.
You must provide an intermediary configuration to support existing business services and Azure. The
business services cannot be rewritten. The business services are not exposed externally.
You need to recommend an approach for accessing the business services.
What should you recommend?

You design an Azure web application. The web application is accessible by default as a standard
cloudapp.net URL.
You need to recommend a DNS resource record type that will allow you to configure access to the
web application by using a custom domain name.
Which DNS record type should you recommend?

A company hosts a website and exposes web services on the company intranet.
The intranet is secured by using a firewall. Company policies prohibit changes to firewall rules.
Devices outside the firewall must be able to access the web services.
