Which two requirements should you identify?

Your company plans to implement a deployment environment.
The company identifies the following requirements for the planned implementation:
Install multiple computers simultaneously.
Use the least amount of network traffic to deploy images.
Automatically start each deployment only when 10 computers are ready for installation.
Ensure that all customers accept the End-User License Agreement (EULA) the first time they start their computer.
A manager at the company recommends deploying generalized images by using Windows Deployment Services (WDS) configured for unicast deployment.
You need to identify which requirements the recommendation meets.
Which two requirements should you identify? (Each correct answer presents part of the solution. Choose two.)

A.
Automatically start the deployment only when 10 computers are ready to be installation.

B.
Install multiple computers simultaneously.

C.
Ensure that all customers accept the EULA the first time they start their computer.

D.
Use the least amount of network traffic to deploy images.

Explanation:
* When performing multicast deployments, the image is copied and then applied. However, when using unicast functionality, the image is applied over the network
and is not copied to the client computer. All data is sent in compressed blocks of data. When these data blocks are received, the data is expanded and written to the
disk.
* WDS uses unicast to send images to clients by default. If you are only imaging 1 or 2 computers, that’s fine; however if you needed to image 50 computers at
once, it would cause enormous amounts of traffic. That is where the multicast comes in.
With WDS, multicast uses a ‘round robin’ approach. Computers can join the multicast whenever they want and if they miss out on the first 100 packets, they will get

them next time around. This means that you can set up 50 computers, start them at the same time, and the image will get sent once, but will be received by all 50
computers. This greatly reduces network bandwidth utilization and speeds up imaging performance when imaging large numbers of machines. (not D)
* As an example, imagine you need to deploy Windows 7 Ultimate to 10 clients. If you used 10 unicast transmissions at the same time, the WDS server
would try to send 10 different images to these clients. Each transmission would be competing with the others for network bandwidth, and each would
be consuming additional resources on the server. (B)
However, if you configured a multicast transmission, you could deploy a single image to all 10 clients simultaneously. Only a single image is being sent
over the network and being processed by the server.
