Q32. You migrate a Windows Server .NET web application to Azure Cloud Services.
You need enable trace logging for the application.
Which two actions should you perform? Each correct answer presents part of the solution.
A. Update the service definition file.
B. Update the Azure diagnostics configuration.
C. Update the service configuration file.
D. Enable verbose monitoring.
E. Update the application web.config file.
Answer: A,B
Explanation: You can use Azure logging right out of the box—it’s part of Azure SDK.
A: Azure Service Definition Schema (.csdef File)
The service definition file defines the service model for an application. The file contains the
definitions for the roles that are available to a cloud service, specifies the service
endpoints, and establishes configuration settings for the service.
B: Take Control of Logging and Tracing in Microsoft Azure
The Microsoft.WindowsAzure.Diagnostics namespace, which inherits from and extends
standard System.Diagnostics classes, enables the use of System.Diagnostics as a logging framework in Azure environment.

Which Azure Power Shell cmdlets and values should you use? To answer, drag the appropriate cmdlet or value to the correct location in the Power Shell command. Each cmdlet or value may be used once, more than once, or not at all. You may need to drag the split bat between panes or scroll to view content.
Answer:
Q34. Your company has two cloud services named CS01 and CS02. You create a virtual machine (VM) in CS02 named Accounts.
You need to ensure that users in CS01 can access the Accounts VM by using port 8080.
What should you do?
A. Create a firewall rule.
B. Configure load balancing.
C. Configure port redirection.
D. Configure port forwarding.
E. Create an end point.
Answer: E
Explanation: All virtual machines that you create in Azure can automatically communicate using a private network channel with other virtual machines in the same cloud service or virtual network. However, other resources on the Internet or other virtual networks require endpoints to handle the inbound network traffic to the virtual machine.

Q35. DRAG DROP
You plan to deploy a cloud service named contosoapp. The service includes a web role named contosowebrole. The web role has an endpoint named restrictedEndpoint.
You need to allow access to restricted Endpoint only from your office machine using the IP address 145.34.67.82.
Which values should you use within the service configuration file? To answer, drag the appropriate value to the correct location in the service configuration file. Each value 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:
Q36. You manage a set of virtual machines (VMs) deployed to the cloud service named fabrikamVM.
You configure auto scaling according to the following parameters:
With an instance range of two to six instances To maintain CPU usage between 70 and 80 percent To scale up one instance at a time With a scale up wait time of 30 minutes To scale down one instance at a time With a scale down wait time of 30 minutes
You discover the following usage pattern of a specific application:
The application peaks very quickly, and the peak lasts for several hours.
CPU usage stays above 90 percent for the first 1 to 1.5 hours after usage
increases.
After 1.5 hours, the CPU usage falls to about 75 percent until application usage
begins to decline.
You need to modify the auto scaling configuration to scale up faster when usage peaks.
What are two possible ways to achieve this goal? Each correct answer presents a complete solution.
A. Decrease the scale down wait time.
B. Decrease the scale up wait time.
C. Increase the number of scale up instances.
D. Increase the scale up wait time.
E. Increase the maximum number of instances.
Answer: B,C
Q37. You manage an Azure virtual network that hosts 15 virtual machines (VMs) on a single subnet which is used for testing a line of business (LOB) application. The application is deployed to a VM named TestWebServiceVM.
You need to ensure that TestWebServiceVM always starts by using the same IP address. You need to achieve this goal by using the least amount of administrative effort.
What should you do?
A. Use the Management Portal to configure TestWebServiceVM.
B. Use RDP to configure TestWebServiceVM.
C. Run the Set-AzureStaticVNetIP PowerShell cmdlet.
D. Run the Get-AzureReservedIP PowerShell cmdlet.
Answer: C
Explanation: Specify a static internal IP for a previously created VM
If you want to set a static IP address for a VM that you previously created, you can do so by using the following cmdlets. If you already set an IP address for the VM and you want to change it to a different IP address, you’ll need to remove the existing static IP address before running these cmdlets. See the instructions below to remove a static IP. For this procedure, you’ll use the Update-AzureVM cmdlet. The Update-AzureVM cmdlet restarts the VM as part of the update process. The DIP that you specify will be assigned after the VM restarts. In this example, we set the IP address for VM2, which is located in cloud service StaticDemo.
Get-AzureVM -ServiceName StaticDemo -Name VM2 | Set-AzureStaticVNetIP -IPAddress
192.168.4.7 | Update-AzureVM

Q38. You administer a Microsoft Azure SQL Database database in the US Central region named contosodb. Contosodb runs on a Standard tier within the SI performance level.
You have multiple business-critical applications that use contosodb.
You need to ensure that you can bring contosodb back online in the event of a natural disaster in the US Central region. You want to achieve this goal with the least amount of downtime.
Which two actions should you perform? Each correct answer presents part of the solution.
A. Upgrade to S2 performance level.
B. Use active geo-replication.
C. Use automated Export.
D. Upgrade to Premium tier.
E. Use point in time restore.
F. Downgrade to Basic tier.
Answer: B,D
Explanation: B: The Active Geo-Replication feature implements a mechanism to provide database redundancy within the same Microsoft Azure region or in different regions (geo-redundancy). One of the primary benefits of Active Geo-Replication is that it provides a database-level disaster recovery solution. Using Active Geo-Replication, you can configure a user database in the Premium service tier to replicate transactions to databases on different Microsoft Azure SQL Database servers within the same or different regions. Cross-region redundancy enables applications to recover from a permanent loss of a datacenter caused by natural disasters, catastrophic human errors, or malicious acts.
D: Active Geo-Replication is available for databases in the Premium service tier only.

Q39. HOTSPOT
You manage two websites for your company. The sites are hosted on an internal server
that is beginning to experience performances issues due to high traffic.
You plan to migrate the sites to Azure Web Sites.
The sites have the following configurations:
In the table below, identity the web hosting plan with the lowest cost for each site. Make only one selection in each column.
Answer:
Q40. You manage a cloud service that utilizes data encryption.
You need to ensure that the certificate used to encrypt data can be accessed by the cloud service application.
What should you do?
A. Upload the certificate referenced in the application package.
B. Deploy the certificate as part of the application package.
C. Upload the certificate's public key referenced in the application package.
D. Use RDP to install the certificate.
Answer: C
Explanation: The developer must deploy the public key with their application so that, when Windows Azure spins up role instances, it will match up the thumbprint in the service definition with the uploaded service certificate and deploy the private key to the role instance. The private key is intentionally non-exportable to the .pfx format, so you won’t be able to grab the private key through an RDC connection into a role instance.
