Your network contains two servers named Server1 and Server2 that have the Streaming Media Services role installed.
Server1 is located in a subnet named Subnet1.
Server2 is located in a subnet named Subnet2.
Server1 has an on-demand publishing point named Content1.
Content1 has a 1-Mbps bit rate.
Server2 is configured as a cache/proxy server.
You need to ensure that users on Subnet2 can stream Content1 from Server2.
The solution must ensure that Content1 is available on Server2 before the users request the stream.
What should you modify?

A.
the Cache settings on Server1

B.
the Prestuff settings on Server2

C.
the Proxy settings on Server1

D.
the Cache settings on Server2

Explanation:
WMS Cache Proxy – Prestuff properties
You can configure the following options on the Prestuff tab for this plug-in.
Item
Description
Prestuff from Stream
Select this option to enable this server to cache content by streaming it from the origin server, even when it is not requested by clients.
Type the URL of the file on the origin server in the URL box (for example, http://server/publishing_point/file), and then select one of the following Prestuff Rate options that specify the speed at which this server caches content from the origin server:
* Maximum Available Bandwidth. Choose this option to cache content from the origin server as fast as the network will allow.
* Content Bit Rate. Choose this option to cache content from the origin server at the same bit rate as the requested content bit rate. Note that for MBR content, the caching speed is the same as the average bit rate of the content.
* Kbps. Enter a value in this box to specify the bit rate at which this server caches content from the origin server.
Prestuff from File
Select this option to enable this server to make a file on an available file storage system, such as a local file system, storage area network (SAN), or network-attached storage (NAS), available for streaming to clients.
To copy the file from file storage to the cache directory on this server and make it available to clients before it is requested, do the following:
Type the UNC path of the file in the Content Path box (for example, serverfolderfile or network_sharefile).
Type the URL that clients must use to stream the file in the Stream URL box (for example, rtsp://server/publishing_point/file or http://server/publishing_point/file).
Select the Copy content to local cache directory check box.
To copy the file from file storage to the cache directory on this server only after a client requests it, do the following:
1. Type the UNC path of the file in the Content Path box.
2. Type the URL that clients must use to stream the file in the Stream URL box. for example,
rtsp://server/publishing_point/file or
http://server/publishing_point/file).
3. Select the Copy content to local cache directory check box.
Make sure that the Copy content to local cache directory check box is not selected.
Note that this server cannot use freshness checking to determine whether the file in the file storage system has been updated. It the file has been updated, you must click Prestuff to cache the updated file to the cache directory.
