Q1. DRAG DROP - (Topic 6)
You are the Azure architect for an organization. You are working with C-level management to assign Azure role-based access control roles to a team within the organization. A single
director oversees two teams, a development team and a test team. The director is wholly responsible for the organization's Azure account, including billing, infrastructure, and access control. The director is the only member of the team with the ability to alter access controls.
You have the following requirements:
. Members of the development team must be able to view or alter Azure infrastructure to support application development. . Members of the test team must be able to view Azure infrastructure to support test cases.
You need to assign built-in Azure role-based access control roles to team members within the organization.
Which role should you assign to each team member? To answer, drag the appropriate role to the correct team member. Each role 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.

Q3. - (Topic 4)
You need to recommend an appropriate solution for the data mining requirements. Which solution should you recommend?
A. Design a schedule process that allocates tasks to multiple virtual machines, and use the Azure Portal to create new VMs as needed.
B. Use Azure HPC Scheduler Tools to schedule jobs and automate scaling of virtual machines.
C. Use Traffic Manager to allocate tasks to multiple virtual machines, and use the Azure Portal to spin up new virtual machines as needed.
D. Use Windows Server HPC Pack on-premises to schedule jobs and automate scaling of virtual machines in Azure.
Answer: C
Explanation: * Microsoft Azure Traffic Manager allows you to control the distribution of user traffic to your specified endpoints, which can include Azure cloud services, websites, and other endpoints. Traffic Manager works by applying an intelligent policy engine to Domain Name System (DNS) queries for the domain names of your Internet resources. Your Azure cloud services or websites can be running in different datacenters across the world.
* Scenario:
Virtual machines:
. The data mining solution must support the use of hundreds to thousands of processing cores. . Minimize the number of virtual machines by using more powerful virtual machines. Each virtual machine must always have eight or more processor cores available. . Allow the number of processor cores dedicated to an analysis to grow and shrink automatically based on the demand of the analysis. . Virtual machines must use remote memory direct access to improve performance.
Task scheduling:
The solution must automatically schedule jobs. The scheduler must distribute the jobs based on the demand and available resources.

Q4. - (Topic 6)
An application currently resides on an on-premises virtual machine that has 2 CPU cores, 4 GB of RAM, 20 GB of hard disk space, and a 10 megabit/second network connection.
You plan to migrate the application to Azure. You have the following requirements:
You must not make changes to the application.
You must minimize the costs for hosting the application.
You need to recommend the appropriate virtual machine instance type.
Which virtual machine tier should you recommend?
A. Network Optimized (A Series)
B. General Purpose Compute, Basic Tier (A Series)
C. General Purpose Compute, Standard Tier (A Series)
D. Optimized Compute (D Series)
Answer: B
Explanation: General purpose compute: Basic tier An economical option for development workloads, test servers, and other applications that don't require load balancing, auto-scaling, or memory-intensive virtual machines.
CPU core range: 1-8 RAM range: 0.75 – 14 GB Disk size: 20-240 GB

Q5. - (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.

Q8. - (Topic 2)
You need to configure the distribution tracking application.
What should you do?
A. Map each role to a single upgrade domain to optimize resource utilization.
B. Design all services as stateless services.
C. Configure operations to queue when a role reaches its capacity.
D. Configure multiple worker roles to run on each virtual machine.
Answer: D
Explanation: * Scenario: distribution tracking application
The system is processor intensive and should be run in a multithreading environment.

Q9. - (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.
