Q12. - (Topic 6)
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.
You need to recommend an approach to enable inbound communication.
What should you recommend?
A. The Azure Access Control Service
B. Windows Azure Pack
C. The Azure Service Bus
D. A web service in an Azure role that relays data to the internal web services
Answer: C
Explanation: The Service Bus Relay is designed for the use-case of taking existing Windows Communication Foundation (WCF) web services and making those services securely accessible to solutions that reside outside the corporate perimeter without requiring intrusive changes to the corporate network infrastructure. Such Service Bus relay services are still hosted inside their existing environment, but they delegate listening for incoming sessions and requests to the cloud-hosted Service Bus.

Q13. - (Topic 6)
You are designing an Azure application. The application includes two web roles and three instances of a worker role. The web roles send requests to the worker role by using one or more Azure Queues.
You need to recommend a queue design for sending requests to the worker role.
What should you recommend?
A. Create a queue for each combination of web roles and worker role instances. Send requests to all worker role instances based on the sending web role.
B. Create a single queue. Send all requests on the single queue.
C. Create a queue for each worker role instance. Send requests on each worker queue by using a round robin rotation.
D. Create a queue for each web role. Send requests on all queues at the same time.
Answer: B
Explanation: To communicate with the worker role, a web role instance places messages on to a queue. A worker role instance polls the queue for new messages, retrieves them, and processes them. There are a couple of important things to know about the way the queue service works in Azure. First, you reference a queue by name, and multiple role instances can share a single queue. Second, there is no concept of a typed message; you construct a message from either a string or a byte array. An individual message can be no more than 64 kilobytes (KB) in size.

Q16. - (Topic 4)
You need to ensure that the website scales. What should you do?
A. Deploy Traffic Manager and configure it to route user traffic to specified endpoints to other Azure datacenters.
B. Enter multiple DNS entries in each virtual network to route requests to other Azure datacenters.
C. Set up a new Azure datacenter to Azure datacenter VPN to enable the solution to communicate across regions.
D. Use a virtual network to route network traffic in a single Azure datacenter.
Answer: C
Explanation: Scenario: The customer-facing website must automatically scale and replicate to locations around the world. Azure ExpressRoute enables you to create private connections between Azure datacenters and infrastructure that’s on your premises or in a colocation environment. ExpressRoute connections do not go over the public Internet, and offer more reliability, faster speeds, lower latencies and higher security than typical connections over the Internet. In some cases, using ExpressRoute connections to transfer data between on-premises and Azure can also yield significant cost benefits.

Topic 5, Northwind traders
Background
Overview
Northwind Electric Cars is the premier provider of private, low-cost transportation in Denver. Northwind drivers are company employees who work together as a team. The founding partners believe that by hiring their drivers as employees, their drivers focus on providing a great customer experience. Northwind Electric Cars has a reputation for offering fast, reliable, and friendly service, due largely to their extensive network of drivers and their proprietary dispatching software named NorthRide.
Northwind Electric Cars drivers depend on frequent, automatic updates for the NorthRide mobile app. The Northwind management team is concerned about unplanned system downtime and slow connection speeds caused by high usage. Additionally, Northwind's inhouse data storage solution is unsustainable because of the new influx of customer data that is retained. Data backups are made periodically on DVDs and stored on-premises at corporate headquarters.
Apps
NorthRide App
Northwind drivers use the NorthRide app to meet customer pickup requests. The app uses a GPS transponder in each Northwind vehicle and Bing Maps APIs to monitor the location of each vehicle in the fleet in real time. NorthRide allows Northwind dispatchers to optimize their driver coverage throughout the city.
When new customers call, the dispatcher enters their pickup locations into NorthRide.
NorthRide identifies the closest available driver. The dispatcher then contacts the driver with the pick-up details. This process usually results in a pick-up time that is far faster than the industry average.
Drivers use NorthRide to track the number of miles they drive and the number of customers they transport. Drivers also track their progress towards their established goals, which are measured by using key performance indicators (KPIs).
NorthRide App 2.0
Northwind Electric Cars is growing quickly. New callers often wait for their calls to be answered because the dispatchers are contacting their drivers to arrange pickups for other customers.
To support the growth of the business, Northwind's development team completes an overhaul of the NorthRide system that it has named NorthRide 2.0. When a dispatcher enters a customer's pickup location, the address and driving directions are automatically sent to the driver who is closest to the customer's pickup location.
Drivers indicate their availability on the NorthRide mobile app and can view progress towards their KPI's in real time. Drivers can also record customer ratings and feedback for each pickup.
Business Requirements
Apps
NorthRideFinder App
Northwind Electric Cars needs a customer-facing website and mobile app that allows customers to schedule pickups. Customers should also be able to create profiles that will help ensure the customer gets a ride faster by storing customer information.
Predictor App
Northwind Electric Cars needs a new solution named Predictor. Predictor is an employeefacing mobile app. The app predicts periods of high usage and popular pickup locations and provides various ways to view this predictive data. Northwind uses this information to better distribute its drivers. Northwind wants to use the latest Azure technology to create this solution.
Other Requirements
On-premises data must be constantly backed up.
Mobile data must be protected from loss, even if connectivity with the backend is lost.
Dispatch offices need to have seamless access to both their primary data center and the applications and services that are hosted in the Azure cloud.
Connectivity needs to be redundant to on-premises and cloud services, while providing a way for each dispatch office to continue to operate even if one or all of the connection options fail.
The management team requires that operational data is accessible 24/7 from any office location.

Q20. - (Topic 1)
You are designing a plan to deploy a new application to Azure. The solution must provide a
single sign-on experience for users.
You need to recommend an authentication type.
Which authentication type should you recommend?
A. SAML credential tokens
B. Azure managed access keys
C. Windows Authentication
D. MS-CHAP
Answer: A
Explanation: A Microsoft cloud service administrator who wants to provide their Azure Active Directory (AD) users with sign-on validation can use a SAML 2.0 compliant SP-Lite profile based Identity Provider as their preferred Security Token Service (STS) / identity provider. This is useful where the solution implementer already has a user directory and password store on-premises that can be accessed using SAML 2.0. This existing user directory can be used for sign-on to Office 365 and other Azure AD-secured resources.
