Answer:

Explanation:

Azure Notification Hubs provide an easy-to-use infrastructure that enables you to send mobile push notifications from any backend (in the cloud or on-premises) to any mobile platform.

Configuration steps include:

1. Configure your Notification Hub

2. Connecting your app to the Notification Hub

3. Send notification from your back-end

You can send notifications using Notification Hubs from any back-end using the REST interface. You do this through a script, not a configuration of Mobile Services. Use Java or PHP for the script.

Answer:

Answer: B

Explanation: The Service Bus relay service enables you to build hybrid applications that run in both an Azure datacenter and your own on-premises enterprise environment. The Service Bus relay facilitates this by enabling you to securely expose Windows Communication Foundation (WCF) services that reside within a corporate enterprise network to the public cloud, without having to open a firewall connection, or require intrusive changes to a corporate network infrastructure.

Answer: A,D

Explanation: * Scenario:

/ Mitigate the need to purchase additional tools for monitoring and debugging.

/A debugger must automatically attach to websites on a weekly basis. The scripts that handle the configuration and setup of debugging cannot work if there is a delay in attaching the debugger.

* A: After publishing your application you can use the Server Explorer in Visual Studio to access your web sites.

After signing in you will see your Web Sites under the Windows Azure node in Server Explorer. Right click on the site that you would like to debug and select Attach Debugger.

D: We need to debug the web site, not an application. We should use the more informative Verbose logging level.

Topic 3, Contoso, Ltd

Background

Overview

Contoso, Ltd., manufactures and sells golf clubs and golf balls. Contoso also sells golf accessories under the Contoso Golf and Odyssey brands worldwide.

Most of the company's IT infrastructure is located in the company's Carlsbad, California, headquarters. Contoso also has a sizable third-party colocation datacenter that costs the company USD $30,000 to $40,000 a month. Contoso has other servers scattered around the United States.

Contoso, Ltd., has the following goals:

✑ Move many consumer-facing websites, enterprise databases, and enterprise web services to Azure.

✑ Improve the performance for customers and resellers who are access company websites from around the world.

✑ Provide support for provisioning resources to meet bursts of demand.

✑ Consolidate and improve the utilization of website- and database-hosting resources.

✑ Avoid downtime, particularly that caused by web and database server updating.

✑ Leverage familiarity with Microsoft server management tools.

Infrastructure

Contoso's datacenters are filled with dozens of smaller web servers and databases that run on under-utilized hardware. This creates issues for data backup. Contoso currently backs up data to tape by using System Center Data Protection Manager. System Center Operations Manager is not deployed in the enterprise.

All of the servers are expensive to acquire and maintain, and scaling the infrastructure takes significant time. Contoso conducts weekly server maintenance, which causes

downtime for some of its global offices. Special events, such as high-profile golf tournaments, create a large increase in site traffic. Contoso has difficulty scaling the web- hosting environment fast enough to meet these surges in site traffic.

Contoso has resellers and consumers in Japan and China. These resellers must use applications that run in a datacenter that is located in the state of Texas, in the United States. Because of the physical distance, the resellers experience slow response times and downtime.

Business Requirements Management and Performance Management

✑ Web servers and databases must automatically apply updates to the operating

system and products.

✑ Automatically monitor the health of worldwide sites, databases, and virtual machines.

✑ Automatically back up the website and databases.

✑ Manage hosted resources by using on-premises tools.

Performance

✑ The management team would like to centralize data backups and eliminate the use of tapes.

✑ The website must automatically scale without code changes or redeployment.

✑ Support changes in service tier without reconfiguration or redeployment.

✑ Site-hosting must automatically scale to accommodate data bandwidth and number of connections.

✑ Scale databases without requiring migration to a larger server.

✑ Migrate business critical applications to Azure.

✑ Migrate databases to the cloud and centralize databases where possible.

Business Continuity and Support Business Continuity

✑ Minimize downtime in the event of regional disasters.

✑ Recover data if unintentional modifications or deletions are discovered.

✑ Run the website on multiple web server instances to minimize downtime and support a high service level agreement (SLA).

Connectivity

✑ Allow enterprise web services to access data and other services located on- premises.

✑ Provide and monitor lowest latency possible to website visitors.

✑ Automatically balance traffic among all web servers.

✑ Provide secure transactions for users of both legacy and modern browsers.

✑ Provide automated auditing and reporting of web servers and databases.

✑ Support single sign-on from multiple domains.

Development Environment

You identify the following requirements for the development environment:

✑ Support the current development team's knowledge of Microsoft web development and SQL Service tools.

✑ Support building experimental applications by using data from the Azure deployment and on-premises data sources.

✑ Mitigate the need to purchase additional tools for monitoring and debugging.

✑ System designers and architects must be able to create custom Web APIs without requiring any coding.

✑ Support automatic website deployment from source control.

✑ Support automated build verification and testing to mitigate bugs introduced during builds.

✑ Manage website versions across all deployments.

✑ Ensure that website versions are consistent across all deployments.

Technical Requirement Management and Performance Management

✑ Use build automation to deploy directly from Visual Studio.

✑ Use build-time versioning of assets and builds/releases.

✑ Automate common IT tasks such as VM creation by using Windows PowerShell workflows.

✑ Use advanced monitoring features and reports of workloads in Azure by using existing Microsoft tools.

Performance

✑ Websites must automatically load balance across multiple servers to adapt to varying traffic.

✑ In production, websites must run on multiple instances.

✑ First-time published websites must be published by using Visual Studio and scaled to a single instance to test publishing.

✑ Data storage must support automatic load balancing across multiple servers.

✑ Websites must adapt to wide increases in traffic during special events.

✑ Azure virtual machines (VMs) must be created in the same datacenter when applicable.

Business Continuity and Support Business Continuity

✑ Automatically co-locate data and applications in different geographic locations.

✑ Provide real-time reporting of changes to critical data and binaries.

✑ Provide real-time alerts of security exceptions.

✑ Unwanted deletions or modifications of data must be reversible for up to one month, especially in business critical applications and databases.

✑ Any cloud-hosted servers must be highly available.

Enterprise Support

✑ The solution must use stored procedures to access on-premises SQL Server data from Azure.

✑ A debugger must automatically attach to websites on a weekly basis. The scripts

that handle the configuration and setup of debugging cannot work if there is a delay in attaching the debugger.

Answer:

Answer:

Explanation:

Box 1:

* Token - A user gains access to an RP application by presenting a valid token that was issued by an authority that the RP application trusts.

* Identity Provider (IP) - An authority that authenticates user identities and issues security tokens, such as Microsoft account (Windows Live ID), Facebook, Google, Twitter, and Active Directory. When Azure Access Control (ACS) is configured to trust an IP, it accepts and validates the tokens that the IP issues. Because ACS can trust multiple IPs at the same time, when your application trusts ACS, you can your application can offer users the option to be authenticated by any of the IPs that ACS trusts on your behalf.

Answer: A
