You are responsible for reverting the application to the form in which it had existed on any day in the previous 35 days. Your task is to choose a backup solution. What would you do?

Question 9

A web application uses table storage in Azure. You create a storage account titled Contoso, that stores a table called CityPopulationData. This table is where all the entities are stored. Your work is to query the table data using OData. Which URL will work?

Question 10

Your task is to develop a Rest API service that furnishes data about various products. An Azure virtual machine (VM) will host the service. Use Azure tables to store the product data. You need to replicate the product data to various locations around the world. You must ensure that API calls, that use the HTTP GET operation, function properly. It should work even when there is no access to the data tables at the primary Azure data center. Your task is to configure storage for the service. Which type of replication will you use?

Question 11

An Azure virtual machine (VM) uses a data disk. Your task is to host an application there. The application executes numerous input and output operations per second. Your task is to disable disk caching for the data disk. Take two approaches. Each approach should be a solution in itself.

Question 12

You use table storage in Azure to store data. The storage analytics logs are empty. Your task is to configure the Azure storage account. At the same time, it must retain logs for the longest period of time that Azure allows. How would you go about it in the Azure management portal?

Question 13

A business enterprise is aiming to boost its virtual network capacity. They are going to do so through the addition of virtual network subscriptions. Your task is to boost the number of subscriptions from 4 to 18. You have to configure the virtual networks. What is your next step?

Question 14

Imagine you are developing a WCF service. You must create a new service instance for each and every client session. Your task is to select an instancing mode. Which instancing mode is the most applicable here?

Question 15

You develop a WCF service. This service will be used to analyze and compare various data sources. This service is consuming a lot of time to finish. The service should be able to meet these requirements.
i) The client must be able to carry on processing while the service is performing.
ii) The WCF service should commence communication with the client application as soon as the processing is over.
Your task is to choose a message pattern to satisfy the above conditions. What is your message pattern of choice?

Question 16

Imagine you are responsible for creating virtual machines (Vms) on Azure. You should be capable of changing the Remote Desktop access settings for the VMs. Likewise, you should also be capable of changing the password for the built-in administrator account on every VM.
