Q31. - (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.

Q32. - (Topic 3)
You need to configure availability for the virtual machines that the company is migrating to Azure.
What should you implement?
A. Traffic Manager
B. Express Route
C. Update Domains
D. Cloud Services
Answer: B
Explanation: ExpressRoute gives you a fast and reliable connection to Azure making it suitable for scenarios like periodic data migration, replication for business continuity, disaster recovery and other high availability strategies. It can also be a cost-effective option for transferring large amounts of data such as datasets for high performance computing applications or moving large VMs between your dev/test environment in Azure and on-premises production environment.

Q33. - (Topic 6)
A company hosts a website and exposes web services on the company intranet.
The intranet is secured by using a firewall. Company policies prohibit changes to firewall
rules.
Devices outside the firewall must be able to access the web services.
You need to recommend an approach to enable inbound communication.
What should you recommend?
A. The Azure Access Control Service
B. Windows Azure Pack
C. The Azure Service Bus
D. A web service in an Azure role that relays data to the internal web services
Answer: C
Explanation: The Service Bus Relay is designed for the use-case of taking existing Windows Communication Foundation (WCF) web services and making those services securely accessible to solutions that reside outside the corporate perimeter without requiring intrusive changes to the corporate network infrastructure. Such Service Bus relay services are still hosted inside their existing environment, but they delegate listening for incoming sessions and requests to the cloud-hosted Service Bus.

Q34. - (Topic 6)
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.

Q35. - (Topic 6)
You are planning an upgrade strategy for an existing Azure application. Multiple instances of the application run in Azure. The management team is concerned about application downtime, due to a business service level agreement (SLA).
You are evaluating which change in your environment will require downtime.
You need to identify the changes to the environment that will force downtime.
Which change always requires downtime?
A. Adding an HTTPS endpoint to a web role
B. Upgrading the hosted service by deploying a new package
C. Changing the value of a configuration setting
D. Changing the virtual machine size
Answer: A
Explanation: If you change the number of endpoints for your service, for example by adding a HTTPS endpoint for your existing Web Role, it will require downtime.
