Answer:
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.

Q8. DRAG DROP - (Topic 1)
You need to recommend data storage mechanisms for the solution.
What should you recommend? To answer, drag the appropriate data storage mechanism to the correct information type. Each data storage mechanism 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.
Answer:
Explanation:
* use Table storage for Contractor information
* Use Blob for Project Images
* Scenario: VanArsdel needs a solution to reduce the number of operations on the contractor information table. Currently, data transfer rates are excessive, and queue length for read/write operations affects performance.
/ A mobile service that is used to access contractor information must have automatically scalable, structured storage
/ Images must be stored in an automatically scalable, unstructured form.
Note: Blob is an acronym for Binary Large object. Basically Blob is a sequence of bytes – just what an application needs. Blob can hold audio, video, email messages, archived files, zip files or a word processing document in a very general way.

Q12. HOTSPOT - (Topic 6)
A company uses Azure for several virtual machine (VM) and website workloads. The company plans to assign administrative roles to a specific group of users. You have a resource group named GROUP1 and a virtual machine named VM2.
The users have the following responsibilities:
You need to assign the appropriate level of privileges to each of the administrators by using the principle of least privilege.
What should you do? To answer, select the appropriate target objects and permission levels in the answer area.
Answer:
Explanation:
* Owner can manage everything, including access.
* Contributors can manage everything except access.
Note: Azure role-based access control allows you to grant appropriate access to Azure AD users, groups, and services, by assigning roles to them on a subscription or resource group or individual resource level.
Q13. HOTSPOT - (Topic 6)
Resources must authenticate to an identity provider. You need to configure the Azure Access Control service.
What should you recommend? To answer, select the appropriate responses for each requirement in the answer area.
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.
Q14. - (Topic 6)
You are designing a solution that will interact with non-Windows applications over unreliable network connections. You have a security token for each non-Windows application.
You need to ensure that non-Windows applications retrieve messages from the solution. Where should you retrieve messages?
A. An Azure Queue
B. The Azure Service Bus Queue
C. An Azure blob storage container that has a private access policy
D. Azure Table storage
Answer: B
Explanation: Any Microsoft or non-Microsoft applications can use a Service Bus REST API to manage and access messaging entities over HTTPS.
By using REST applications based on non-Microsoft technologies (e.g. Java, Ruby, etc.) are allowed not only to send and receive messages from the Service Bus, but also to create or delete queues, topics and subscription in a given namespace.
Reference: Service Bus Explorer https://code.msdn.microsoft.com/windowsazure/service-bus-explorer-f2abca5a
Q15. - (Topic 6)
You are designing an Azure web application. The solution will be used by multiple customers. Each customer has different business logic and user interface requirements. Not all customers use the same version of the .NET runtime.
You need to recommend a deployment strategy. What should you recommend?
A. Deploy with multiple web role instances.
B. Deploy each application in a separate tenant.
C. Deploy all applications in one tenant.
D. Deploy with multiple worker role instances.
Answer: B
Explanation: There are two types of tenant environments. The simplest type is a single- tenant application where one customer has 100% dedicated access to an application’s process space. A single Tenant Applications has a separate, logical instance of the application for each customer or client. A single tenant application is much more predictable and stable by its nature since there will never be more than one dedicated customer at any point in time in that VM. That customer has all of its users accessing that dedicated instance of the application.
