Q3. 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

Q4. You are designing an Azure application. The application includes services hosted in different geographic locations. The service locations may change.

You must minimize the cost of communication between services.

You need to recommend an approach for data transmission between your application and Azure services. The solution must minimize administrative effort.

What should you recommend?

A. Azure Table storage

B. Service Bus queue

C. Service Management API

D. Azure Queue storage

Answer: B

Explanation:

The cost of ACS transactions is insignificant when performing messaging operations against Service Bus queues. Service Bus acquires one ACS token per a single instance of the messaging factory object. The token is then reused until it expires, after about 20 minutes. Therefore, the volume of messaging operations in Service Bus is not directly proportional to the amount of ACS transactions required to support these operations.

Q5. You manage a cloud service that has one Web Role instance, and several Worker Role instances. The cloud service has multiple tiers. Different groups develop and maintain each tier.

You need to ensure that the cloud service remains highly available and responsive when the Worker Roles are performing extensive work.

What should you do?

A. Create an availability set for each tier of the application.

B. Implement auto-scaling for the Worker Roles.

C. Create a resource group.

D. Create an availability set with two or more virtual machines.

Answer: B

Q6. You design an Azure web application. The web application is accessible by default as a standard cloudapp.net URL.

You need to recommend a DNS resource record type that will allow you to configure access to the web application by using a custom domain name.

Which DNS record type should you recommend?

A. SRV

B. MX

C. CNAME

D. A

Answer: C

Explanation:

A CNAME record maps a specific domain, such as contoso.com or www.contoso.com, to a canonical domain name. In this case, the canonical domain name is the

<myapp>.cloudapp.net domain name of your Azure hosted application. Once created, the CNAME creates an alias for the <myapp>.cloudapp.net. The CNAME entry will resolve to the IP address of your <myapp>.cloudapp.net service automatically, so if the IP address of the cloud service changes, you do not have to take any action.

Incorrect: Not D:

* Since an A record is mapped to a static IP address, it cannot automatically resolve changes to the IP address of your Cloud Service.

* An A record maps a domain, such as contoso.com or www.contoso.com, or a wildcard domain such as *.contoso.com, to an IP address. In the case of an Azure Cloud Service, the virtual IP of the service. So the main benefit of an A record over a CNAME record is that you can have one entry that uses a wildcard, such as *.contoso.com, which would handle requests for multiple sub-domains such as mail.contoso.com, login.contoso.com, or www.contso.com.

Q7. A company creates an API and makes it accessible on an Azure website. External partners use the API occasionally. The website uses the Standard web hosting plan.

Partners report that the first API call in a sequence of API calls occasionally takes longer than expected to run. Subsequent API calls consistently perform as expected.

You need to ensure that all API calls perform consistently. What should you do?

A. Configure the website to use the Basic web hosting plan

B. Enable Always On support.

C. Configure the website to automatically scale.

D. Add a trigger to the web.config file for the website that causes the website to recycle periodically.

Answer: B

Explanation:

By default, web apps are unloaded if they are idle for some period of time. This lets the system conserve resources. In Basic or Standard mode, you can enable Always On to keep the app loaded all the time. If your app runs continuous WebJobs or runs WebJobs triggered using a CRON expression, you should enable Always On, or the web jobs may not run reliably.

Q8. You design an Azure application that processes images. The maximum size of an image is 10 MB. The application includes a web role that allows users to upload images and a worker role with multiple instances that processes the images. The web role communicates with the worker role by using an Azure Queue service.

You need to recommend an approach for storing images that minimizes storage transactions.

What should you recommend?

A. Store images in Azure Blob service. Store references to the images in the queue.

B. Store images in the queue.

C. Store images in OneDrive attached to the worker role instances. Store references to the images in the queue.

D. Store images in local storage on the web role instance. Store references to the images in the queue.

Answer: A

Explanation:

Azure Queues provide a uniform and consistent programming model across queues, tables, and BLOBs u2013 both for developers and for operations teams.

Microsoft Azure blob storage can be used to store the image data, the application can use a worker role in Azure to perform background processing tasks on the images, how the application may use shared access signatures to control access to the images by users. Azure blobs provide a series of containers aimed at storing text or binary data. Block blob containers are ideal for streaming data, while page blob containers can be used for random read/write operations.

Q9. You have business services that run on an on-premises mainframe server.

You must provide an intermediary configuration to support existing business services and Azure. The business services cannot be rewritten. The business services are not exposed externally.

You need to recommend an approach for accessing the business services. What should you recommend?

A. Connect to the on-premises server by using a custom service in Azure.

B. Expose the business services to the Azure Service Bus by using a custom service that uses relay binding.

C. Expose the business services externally.

D. Move all business service functionality to Azure.

Answer: B

Explanation:

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.

Q10. You are designing an Azure application that will use a worker role. The worker role will create temporary files.

You need to minimize storage transaction charges. Where should you create the files?

A. In Azure local storage

B. In Azure Storage page blobs

C. On an Azure Drive

D. In Azure Storage block blobs

Answer: A

Explanation:

Local storage is temporary in Azure. So, if the virtual machine supporting your role dies and cannot recover, your local storage is lost! Therefore, Azure developers will tell you, only volatile data should ever be stored in local storage of Azure.
