Q51. - (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.

Q52. - (Topic 1)

You need to prepare the implementation of data storage for the contractor information app. What should you?

A. Create a storage account and implement multiple data partitions.

B. Create a Cloud Service and a Mobile Service. Implement Entity Group transactions.

C. Create a Cloud Service and a Deployment group. Implement Entity Group transactions.

D. Create a Deployment group and a Mobile Service. Implement multiple data partitions.

Answer: B

Explanation:

* 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

* The basic unit of deployment and scale in Azure is the Cloud Service. Reference: Performing Entity Group Transactions

Answer: A


Q55. HOTSPOT - (Topic 6)

You are migrating an on-premises application to Azure. The application requires secure storage of database connection strings. When the application is running locally, the connection strings are encrypted with an X509 certificate prior to being stored on disk. The X509 certificate is part of a trust chain to allow the certificate to be revoked by the Certificate Authority if a security breech is suspected.

The application must run on Azure. The X509 certificate must never be stored on disk or in RAM memory. A Certificate Authority must be able to revoke the certificate.

You need to configure Azure Key value.

How should you construct the Azure PowerShell script? To answer, select the appropriate A?ure PowerShell commands in the answer area.

Answer:


Q56.  - (Topic 6)

You are preparing an application to run on Azure virtual machines (VMs). The VMs will be backed up using Azure Backup.

The application maintains its state in three binary files stored on disk. Changes in application state require that all three files be updated on disk. If only one or two of the files are updated on disk, work is lost and the system is in an inconsistent state.

You need to ensure that when a backup occurs, the application's data is always in a consistent state.

What should you do?

A. Disable caching for the VM’s virtual hard disks.

B. Use Premium Storage for the VM’s virtual hard disks.

C. Implement the Volume Shadow Copy Service (VSS) API in the application.

D. Store the application files on an Azure File Service network share.

Answer: A


Q57. You need to implement the security requirements. What should you implement?

A. the GraphAPI to query the directory

B. LDAP to query the directory

C. single sign-on

D. user certificates 

Answer: C


Q58.  - (Topic 6)

You are the administrator for a company named Contoso, Ltd.

Contoso also has an Azure subscription and uses many on-premises Active Directory products as roles in Windows Server including the following:

✑ Active Directory Domain Services (AD DS)

✑ Active Directory Certificate Services (AD CS)

✑ Active Directory Rights Management Services (AD RMS)

✑ Active Directory Lightweight Directory Services (AD LDS)

✑ Active Directory Federation Services (AD FS).

Contoso must use the directory management services available in Azure Active Directory.

You need to provide information to Contoso on the similarities and differences between Azure Active Directory and the Windows Server Active Directory family of services.

Which feature does Azure Active Directory and on-premises Active Directory both support?

A. Using the GraphAPI to query the directory

B. Issuing user certificates

C. Supporting single sign-on (SSO)

D. Querying the directory with LDAP

Answer: C

Explanation: AD FS supports Web single-sign-on (SSO) technologies, and so does Azure Active Directory.

If you want single sign on we usually suggest using ADFS if you’re a Windows shop. Going forward though, Azure Active Directory is another alternative you can use.

Q59.  - (Topic 4)

You need to ensure that the website scales. What should you do?

A. Deploy Traffic Manager and configure it to route user traffic to specified endpoints to other Azure datacenters.

B. Enter multiple DNS entries in each virtual network to route requests to other Azure datacenters.

C. Set up a new Azure datacenter to Azure datacenter VPN to enable the solution to communicate across regions.

D. Use a virtual network to route network traffic in a single Azure datacenter.

Answer: C

Explanation: Scenario: The customer-facing website must automatically scale and replicate to locations around the world.

Azure ExpressRoute enables you to create private connections between Azure datacenters and infrastructure that’s on your premises or in a colocation environment. ExpressRoute connections do not go over the public Internet, and offer more reliability, faster speeds, lower latencies and higher security than typical connections over the Internet. In some cases, using ExpressRoute connections to transfer data between on-premises and Azure can also yield significant cost benefits.
