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.

DRAG DROP
You need to provide a data access solution for the NorthRide app.
Which four actions should you perform in sequence? To answer, move the appropriate actions from
the list of actions to the answer area and arrange them in the correct order.

Answer: See the explanation

Explanation:
Box 1: Create a service namespace under Service Bus
Box 2: Obtain the default management credentials for the namespace.
Box 3: Configure the application to use Service Bus Relay
Box 4: Configure Service Bus Queue

Note:
Box 1: Create a service namespace under Service Bus
To begin using Service Bus queues in Azure, you must first create a service namespace. A namespace
provides a scoping container for addressing Service Bus resources within your application.
Box 2: Obtain the default management credentials for the namespace.
In order to perform management operations, such as creating a queue on the new namespace, you
must obtain the management credentials for the namespace.
Box 3: Configure the application to use Service Bus Relay
When you create an application that uses Service Bus, you must add a reference to the Service Bus
assembly and include the corresponding namespaces.
The Service Bus NuGet package is the easiest way to get the Service Bus API and to configure your
application with all of the Service Bus dependencies.
After installing this package you are now ready to write code for Service Bus.
Box 4: Configure Service Bus Queue
This would include:
* set up a Service Bus connection string
* create a queue
* provide code to send/receive messages from the queue

The answer is incorrect. The question states “you need to provide a data access solution”. Data Access being the key.

In the case study it states “Access must be secured in NorthRide without opening a firewall port.”, which tells us to use service bus relay. There is nothing in the information about using a queue in NorthRide, only NorthRideFinder.

Therefore based on this webpage –
https://azure.microsoft.com/en-us/documentation/articles/service-bus-dotnet-how-to-use-relay/

The answer should be:
Box 1: Create a service namespace under Service Bus
Box 2: Obtain the default management credentials for the namespace.
Box 3: Configure the Service Bus to consume a web service
Box 4: Configure the application to use Service Bus Relay

about the queues, it does say : “Customer pickup requests from NorthRideFinder must be asynchronous”.

just noticed it said only NorthRideFinder

no, it says “Customer pickup requests from NorthRideFinder must be asynchronous”

Box 1: Create a service namespace under Service Bus
Box 2: Obtain the default management credentials for the namespace.
Box 3: Configure the Service Bus to consume a web service
Box 4: Configure the application to use Service Bus Relay

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.

Correct order…
Box 1: Create a service namespace under Service Bus
Box 2: Obtain the default management credentials for the namespace.
Box 3: Configure Service Bus Queue – with queue SB can’t do anything.
Box 4: Configure the application to use Service Bus Relay – only when SB is ready, app can consume.

– without* queue SB can’t do anything

I agree with Bob answer:

The answer should be:
Box 1: Create a service namespace under Service Bus
Box 2: Obtain the default management credentials for the namespace.
Box 3: Configure the Service Bus to consume a web service
Box 4: Configure the application to use Service Bus Relay
