Which of the following applications would be a good candidate to move to a cloud-based platform?
Mission critical financial data
Customer Relationship Management (CRM)
Database that requires a low latency for indexing
Answer: B Explanation:
The best place to start is with new applications that are customer-, partner- and employee- facing.
Cloud CRM (or CRM cloud) means any customer relationship management (CRM) technology where the CRM software, CRM tools and the organization#39;s customer data resides in the cloud and is delivered to end-users via the Internet.
Cloud CRM typically offers access to the application via Web-based tools (or Web browser) logins where the CRM system administrator has previously defined access levels across the organization. Employees can log in to the CRM system, simultaneously, from any Internet-enabled computer or device. Often, cloud CRM provide users with mobile apps to make it easier to use the CRM on smartphones and tablets.

Which of the following is a potential advantage of using Storage as a Service?
Data is accessible when the Internet is not functioning
In-house IT staff controls all data
Increase in encryption technologies
Decrease in IT management of the platform
Answer: D Explanation:
One advantages of SaaS is that is makes it easy to 鈥渕obilize鈥?your workforce because users can access SaaS apps and data from any Internet-connected computer or mobile device. You don’t need to worry about developing apps to run on different types of computers and devices because the service provider has already done so. In addition, you don’t need to bring special expertise onboard to manage the security issues inherent in mobile computing. A carefully chosen service provider will ensure the security of your data, regardless of the type of device consuming it.

An application sends Azure push notifications to a client application that runs on Windows Phone, iOS, and Android devices.
Users cannot use the application on some devices. The authentication mechanisms that the application uses are the source of the problem.
You need to monitor the number of notifications that failed because of authentication errors.
Which three metrics should you monitor? Each correct answer presents part of the solution.
Microsoft Push Notification Service (MPNS) authentication errors
External notification system errors
Apple Push Notification Service (APNS) authentication errors
Windows Push Notification Services (WNS) authentication errors
Google Cloud Messaging (GCM) authentication errors

You are designing a Windows Azure application that will generate events for multiple clients.
Client web services might be behind NAT gateways.
You need to recommend an approach that will allow you to broadcast the events to clients. What should you recommend?
Use ADO.NET Data Services and provide a shared key to clients.
Use Windows Azure Queues and provide a shared key to clients.
Use Windows Azure Table storage and provide a shared key to clients.
Use the Windows Azure AppFabric Service Bus and provide a shared secret to clients.
Answer: D Explanation:
The Windows Azure Service Bus provides a hosted, secure, and widely available infrastructure for widespread communication, large-scale event distribution, naming, and service publishing. The Service Bus provides connectivity options for Windows Communication Foundation (WCF) and other service endpoints including REST endpoints –
– that would otherwise be difficult or impossible to reach. Endpoints can be located behind network address translation (NAT) boundaries, or bound to frequently-changing, dynamically-assigned IP addresses, or both. The Service Bus provides both quot;relayedquot; and quot;brokeredquot; messaging capabilities. In the relayed messaging pattern, the relay service supports direct one-way messaging, request/response messaging, and peer-to- peer messaging. Brokered messaging provides durable, asynchronous messaging components such as Queues, Topics, and Subscriptions, with features that support publish-subscribe and temporal decoupling

You are developing a web application that uses Azure push notifications to interact with users.
You need to send a text notification to users to alert them that the application is ready to test.
How should you complete the relevant code? To answer, drag the appropriate code segment to the correct location. Each code segment may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.

A cloud usage metering scheme allows for which of the following customer chargeback alternatives?
Answer: D Explanation:
A range of approaches have been developed for implementing chargeback in an organization, as summarized in the figure below. The degree of complexity, degree of difficulty, and cost to implement decreases from the top of the chart [service-based pricing (SBP)], to the bottom [high-level allocation (HLA)]. HLA is the simplest method; it uses a straight division of IT costs based on a generic metric such as headcount. Slightly more effort to implement is low-level allocation (LLA), which bases consumer costs on something more related to IT activity such as the number of users or servers. Direct cost (DC) more closely resembles a time and materials charge but is often tied to headcount as well.

You connect to an existing service over the network by using HTTP. The service listens on HTTP port 80. You plan to create a test environment for this existing service by using an Azure virtual machine (VM) that runs Windows Server.
The service must be accessible from the public Internet over HTTP port 8080. You need to configure the test environment.
Which two actions should you take? Each correct answer presents part of the solution.
Configure an endpoint to route traffic from port 8080 to port 80.
Configure an endpoint to route traffic from port 80 to port 8080.
Ensure that the public IP address is configured as a static IP address.
Configure the Windows Server firewall to allow incoming and outgoing traffic on port 8080.
Configure the Windows Server firewall to allow incoming and outgoing traffic on port 80.
