mobile application, online training for retail store employees, and moving the current web application and other
services to the cloud.
The marketing team hopes to see an increase in the up-time for the web application. The team would also like
to allow users to use social logins in addition to the current username and password system.
Fourth Coffee has chosen Microsoft Azure to support their initiatives.
Current environment
In the Azure portal, you create an Azure Mobile App for the API. You create a Service Bus queue in Azure and
install the Azure Storage SDK for Node.js.
Problem statements
The mobile team attempts to use continuous deployment with the Azure App Service and new API project. They
receive the following error message: “Unable to access http://fourthcoffeeapi.azurewebsites.net/: Failed to
connect to https://fourthcoffeeapi.scm.azurewebsites.net/”
Business requirements
Web Application
You must increase up-time for the application.
The application must support additional regions and languages.
Marketing must be able to validate the web application before updates to the application are published to the
production environment.
Mobile
The marketing team must be able to send frequent and timely updates to specific users and devices
including Apple iPad, iPhone, Android, Windows, and Windows Phone devices.

You must update the deployment process to support cloud deployments.
All data must be formatted as JSON during transport.
You must implement Team Foundation Version Control (TFVC) as the version control system for the web
application.
Incoming messages to the API must be persisted to queue storage to ensure they are delivered and
processed. You must restrict the size of messages between the mobile app and the API to no more than 5
gigabytes (GB).
The web application must use geo-redundant replication.
Mobile
You must use Node.js as a technology platform. You must support all mobile initiatives when possible.
You must implement Git as the version control system for the mobile app.
You must develop a REST API by using Node.js Express, and MongoDB. You must use the Mobile Apps

applications.
You must implement Multi-Factor Authentication.
The web application and the API must be able to recover from a disaster.
Scaling
The web application and API must auto-scale according to the following rules:
Scale up by one instance if CPU is above 70%.
Scale down by one instance if CPU is below 50%.
Training
Streaming must include Content Delivery Network (CDN) capabilities to support global locations.
Content must be encrypted and protected by using AES and PlayReady.
Streaming must include one gigabit (GB) per second of dedicated egress capacity.
All videos must use adaptive bitrate MP4 encoded content and include a streaming manifest file (.ism).

Which three 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.Select and Place:
Answer: 
incorrect. How can you add endpoints without creating a traffic manager first?

Right,
1) create and deploy new web app.
2) create a new traffic manager.
3) add new endpoints with cname to Traffic manager.

create a new traffic manager – shouldn’t it be Failover instead of Performance?
0
0
There is no such thing as failover Traffic manager.
Priority: Select Priority when you want to use a primary service endpoint for all traffic, and provide backups in case the primary or the backup endpoints are unavailable.
Weighted: Select Weighted when you want to distribute traffic across a set of endpoints, either evenly or according to weights, which you define.
Performance: Select Performance when you have endpoints in different geographic locations and you want end users to use the “closest” endpoint in terms of the lowest network latency.
Geographic: Select Geographic so that users are directed to specific endpoints (Azure, External, or Nested) based on which geographic location their DNS query originates from. This empowers Traffic Manager customers to enable scenarios where knowing a user’s geographic region and routing them based on that is important. Examples include complying with data sovereignty mandates, localization of content & user experience and measuring traffic from different regions.

failover is same as priority

but definitely there is no such term in the portal “failover”, so I believe demisa is correct and the option we select shall be “method set to performance”
