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 webhosting 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.

Q6. - (Topic 1)
You need to design the system that alerts project managers to data changes in the contractor information app.
Which service should you use?
A. Azure Mobile Service
B. Azure Service Bus Message Queueing
C. Azure Queue Messaging
D. Azure Notification Hub
Answer: C
Explanation: * Scenario:
/ Mobile Apps: Event-triggered alerts must be pushed to mobile apps by using a custom
Node.js script.
/ The service level agreement (SLA) for the solution requires an uptime of 99.9%
* If you are already using Azure Storage Blobs or Tables and you start using queues, you are guaranteed 99.9% availability. If you use Blobs or Tables with Service Bus queues, you will have lower availability.
Note: Microsoft Azure supports two types of queue mechanisms: Azure Queues and Service Bus Queues. / Azure Queues, which are part of the Azure storage infrastructure, feature a simple REST-based Get/Put/Peek interface, providing reliable, persistent messaging within and between services. / Service Bus queues are part of a broader Azure messaging infrastructure that supports queuing as well as publish/subscribe, Web service remoting, and integration patterns.

Q11. - (Topic 5)
You need to recommend a technology for processing customer pickup requests.
Which technology should you recommend?
A. Notification hub
B. Queue messaging
C. Mobile Service with push notifications
D. Service Bus messaging
Answer: D
Explanation: Service Bus queues are part of a broader Azure messaging infrastructure
that supports queuing as well as publish/subscribe, Web service remoting, and integration
patterns.
Service Bus Queue support Push-style API (while Azure Queue messaging does not).
Incorrect:
Not A: Notification Hub is only used to push notification, not for processing requests.
Not B As a solution architect/developer, you should consider using Azure Queues when:
*
Your application must store over 80 GB of messages in a queue, where the messages have a lifetime shorter than 7 days.
*
Your application wants to track progress for processing a message inside of the queue. This is useful if the worker processing a message crashes. A subsequent worker can then use that information to continue from where the prior worker left off.
You require server side logs of all of the transactions executed against your queues.
Not C: To process the messages we do not need push notification.

Q15. - (Topic 6)
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. SRV
B. MX
C. CNAME
D. A
Answer: C
Explanation: A CNAME record maps a specific domain, such as contoso.com or www.contoso.com, to a canonical domain name. In this case, the canonical domain name is the <myapp>.cloudapp.net domain name of your Azure hosted application. Once created, the CNAME creates an alias for the <myapp>.cloudapp.net. The CNAME entry will resolve to the IP address of your <myapp>.cloudapp.net service automatically, so if the IP address of the cloud service changes, you do not have to take any action.
Incorrect: Not D:
*
Since an A record is mapped to a static IP address, it cannot automatically resolve changes to the IP address of your Cloud Service.
*
An A record maps a domain, such as contoso.com or www.contoso.com, or a wildcard domain such as *.contoso.com, to an IP address. In the case of an Azure Cloud Service, the virtual IP of the service. So the main benefit of an A record over a CNAME record is that you can have one entry that uses a wildcard, such as *.contoso.com, which would handle requests for multiple sub-domains such as mail.contoso.com, login.contoso.com, or
www.contso.com.

Topic 2, Trey Research
Background
Overview
Trey Research conducts agricultural research and sells the results to the agriculture and food industries. The company uses a combination of on-premises and third-party server clusters to meet its storage needs. Trey Research has seasonal demands on its services, with up to 50 percent drops in data capacity and bandwidth demand during low-demand periods. They plan to host their websites in an agile, cloud environment where the company can deploy and remove its websites based on its business requirements rather than the requirements of the hosting company.
A recent fire near the datacenter that Trey Research uses raises the management team's awareness of the vulnerability of hosting all of the company's websites and data at any single location. The management team is concerned about protecting its data from loss as a result of a disaster.
Websites
Trey Research has a portfolio of 300 websites and associated background processes that are currently hosted in a third-party datacenter. All of the websites are written in ASP.NET, and the background processes use Windows Services. The hosting environment costs Trey Research approximately S25 million in hosting and maintenance fees.
Infrastructure
Trey Research also has on-premises servers that run VMs to support line-of-business applications. The company wants to migrate the line-of-business applications to the cloud, one application at a time. The company is migrating most of its production VMs from an aging VMWare ESXi farm to a Hyper-V cluster that runs on Windows Server 2012.
Applications
DistributionTracking
Trey Research has a web application named Distributiontracking. This application constantly collects realtime data that tracks worldwide distribution points to customer retail sites. This data is available to customers at all times.
The company wants to ensure that the distribution tracking data is stored at a location that is geographically close to the customers who will be using the information. The system must continue running in the event of VM failures without corrupting data. The system is processor intensive and should be run in a multithreading environment.
HRApp
The company has a human resources (HR) application named HRApp that stores data in an on-premises SQL Server database. The database must have at least two copies, but data to support backups and business continuity must stay in Trey Research locations only.
The data must remain on-premises and cannot be stored in the cloud.
HRApp was written by a third party, and the code cannot be modified. The human resources data is used by all business offices, and each office requires access to the entire database. Users report that HRApp takes all night to generate the required payroll reports, and they would like to reduce this time.
MetricsTracking
Trey Research has an application named MetricsTracking that is used to track analytics for the DistributionTracking web application. The data MetricsTracking collects is not customer-facing. Data is stored on an on-premises SQL Server database, but this data should be moved to the cloud. Employees at other locations access this data by using a remote desktop connection to connect to the application, but latency issues degrade the functionality.
Trey Research wants a solution that allows remote employees to access metrics data without using a remote desktop connection. MetricsTracking was written in-house, and the development team is available to make modifications to the application if necessary.
However, the company wants to continue to use SQL Server for MetricsTracking.
Business Requirements
Business Continuity
You have the following requirements:
Move all customer-facing data to the cloud.
Web servers should be backed up to geographically separate locations,
If one website becomes unavailable, customers should automatically be routed to websites that are still operational.
Data must be available regardless of the operational status of any particular website.
The HRApp system must remain on-premises and must be backed up.
The MetricsTracking data must be replicated so that it is locally available to all Trey Research offices.
Auditing and Security
You have the following requirements:
Both internal and external consumers should be able to access research results.
Internal users should be able to access data by using their existing company credentials without requiring multiple logins.
Consumers should be able to access the service by using their Microsoft credentials.
Applications written to access the data must be authenticated.
Access and activity must be monitored and audited.
Ensure the security and integrity of the data collected from the worldwide distribution points for the distribution tracking application.
Storage and Processing
You have the following requirements:
Provide real-time analysis of distribution tracking data by geographic location.
Collect and store large datasets in real-time data for customer use.
Locate the distribution tracking data as close to the central office as possible to improve bandwidth.
Co-locate the distribution tracking data as close to the customer as possible based on the customer's location.
Distribution tracking data must be stored in the JSON format and indexed by metadata that is stored in a SQL Server database.
Data in the cloud must be stored in geographically separate locations, but kept with the same political boundaries.
Technical Requirements
Migration
You have the following requirements:
Deploy all websites to Azure.
Replace on-premises and third-party physical server clusters with cloud-based solutions.
Optimize the speed for retrieving exiting JSON objects that contain the distribution tracking data.
Recommend strategies for partitioning data for load balancing.
Auditing and Security
You have the following requirements:
