Q11. DRAG DROP - (Topic 1)
You need to recommend data storage mechanisms for the solution.
What should you recommend? To answer, drag the appropriate data storage mechanism to the correct information type. Each data storage mechanism 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.
Answer:
Explanation:
* use Table storage for Contractor information
* Use Blob for Project Images
* Scenario: VanArsdel needs a solution to reduce the number of operations on the contractor information table. Currently, data transfer rates are excessive, and queue length for read/write operations affects performance.
/ A mobile service that is used to access contractor information must have automatically scalable, structured storage
/ Images must be stored in an automatically scalable, unstructured form.
Note: Blob is an acronym for Binary Large object. Basically Blob is a sequence of bytes – just what an application needs. Blob can hold audio, video, email messages, archived files, zip files or a word processing document in a very general way.
Q12. - (Topic 6)
A company has 10 on-premises SQL databases. The company plans to move the databases to SQL Server 2012 that runs in Azure Infrastructure-as-a-Service (IaaS). After migration, the databases will support a limited number of Azure websites in the same Azure Virtual Network.
You have the following requirements:
✑ You must restore copies of existing on-premises SQL databases to the SQL servers that run in Azure IaaS.
✑ You must be able to manage the SQL databases remotely.
✑ You must not open a direct connection from all of the machines on the on- premises network to Azure.
✑ Connections to the databases must originate from only five Windows computers.
You need to configure remote connectivity to the databases. Which technology solution should you implement?
A. Azure Virtual Network site-to-site VPN
B. Azure Virtual Network multi-point VPN
C. Azure Virtual Network point-to-site VPN
D. Azure ExpressRoute
Answer: C
Explanation: A point-to-site VPN would meet the requirements.

Q13. - (Topic 5)
You need to design the authentication solution for the NorthRide app. Which solution should you use?
A. Azure Active Directory Basic with multi-factor authentication for the cloud and on- premises users.
B. Active Directory Domain Services with mutual authentication
C. Azure Active Directory Premium and add multi-factor authentication the for cloud users
D. Active Directory Domain Services with multi-factor authentication
Answer: C
Explanation: * Scenario: The NorthRide app must use an additional level of authentication other than the employee's password.
* Azure Multi-Factor Authentication is the multi-factor authentication service that requires users to also verify sign-ins using a mobile app, phone call or text message. It is available to use with Azure Active Directory, to secure on-premise resources with the Azure Multi- Factor Authentication Server, and with custom applications and directories using the SDK.

Q14. HOTSPOT - (Topic 1)
You need to design the contractor information app.
What should you recommend? To answer, select the appropriate options in the answer area.
Answer:
Explanation:
/ They also plan to extend their on-premises Active Directory into Azure for mobile app authentication
/ VanArsdel mobile app must authenticate employees to the company's Active Directory.
Q15. - (Topic 5)
You need to recommend a solution that meets the requirements for data storage for the NorthRide app.
What should you include in the recommendation?
A. Azure Remote App
B. Azure Service Bus
C. Azure Connect
D. Azure SQL Database
Answer: B
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).

Q19. - (Topic 6)
You are designing an Azure application that stores data.
You have the following requirements:
✑ The data storage system must support storing more than 500 GB of data.
✑ Data retrieval must be possible from a large number of parallel threads.
✑ Threads must not block each other.
You need to recommend an approach for storing data. What should you recommend?
A. Azure Notification Hubs
B. A single SQL database in Azure
C. Azure Queue storage
D. Azure Table storage
Answer: D
Explanation: * Azure Table Storage can be useful for applications that must store large amounts of nonrelational data, and need additional structure for that data. Tables offer key- based access to unschematized data at a low cost for applications with simplified data- access patterns. While Azure Table Storage stores structured data without schemas, it does not provide any way to represent relationships between the data.
* As a solution architect/developer, consider using Azure Table Storage when:
/ Your application stores and retrieves large data sets and does not have complex relationships that require server-side joins, secondary indexes, or complex server-side logic.
/ You need to achieve a high level of scaling without having to manually shard your dataset.

Q20. - (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.
