QUESTION 21
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.

QUESTION 22
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:
You can also use CNAME or A records to associate a custom domain name with your VM. When you use A records, however, you need to note that the VIP of your VM might change. When you deallocate a VM, the associated VIP is released. And when the VM is restarted later, a new VIP will be picked and assigned. If you want to ensure that your VM has a static public IP address, you’ll need to confi gure a static IP address for it as described earlier.

QUESTION 23
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.

QUESTION 24
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
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.

What should you recommend?
A. Azure Access Control
B. Azure Content Delivery Network (CDN)
C. Azure Service Bus
D. Azure Site-to-Site VPN
Answer: D
Explanation:
IPsec can be used on Azure Site-to-Site VPN connections. Distributed applications can used the IPSec VPN connections to communicate.

QUESTION 27
You have several virtual machines (VMs) that run in Azure.
You also have a single System Center 2012 R2 Configuration Manager (SCCM) primary site on-premises.
You have the following requirements:
– All VMs must run on the same virtual network.
– Network traffic must be minimized between the on-premises datacenter and Azure.
– The solution minimize complexity.
You need to use SCCM to collect inventory and deploy software to Azure VMs.
What should you do first?
A. Configure client push for the Azure virtual network.
B. Enable and configure Operations Insights in Azure.
C. Install a cloud distribution point on an Azure VM.
D. Install a secondary site underneath the primary site onto an Azure VM.
Answer: C
Explanation:
Cloud-based distribution Point, a Configuration Manager Site System Role in the Cloud Much of the Configuration Manager topology is made up of distribution points, they are very helpful in many situations where bandwidth and geographical separation are the facts of life, but also hard to manage if you have hundreds or even thousands of them.
This feature started with the vision that it makes perfect sense to have big distribution points in the Windows Azure cloud where one should not worry about things like (but not limited to) size, performance, reliability, security, access from all around the world, hardware/software update issues etc.
Note: Content management in System Center 2012 Configuration Manager provides the tools for you to manage content files for applications, packages, software updates, and operating system deployment. Configuration Manager uses distribution points to store files that are required for software to run on client computers. These distribution points function as distribution centers for the content files and let users download and run the software. Clients must have access to at least one distribution point from which they can download the files.
