Which inbound ports should you allow on the hardware firewall?

Your network contains a hardware firewall between the internal network and the Internet.

On the internal network, you install a new server named Server1.

Server1 has the Streaming Media Services role installed.
You configure Server1 to use only real-time streaming protocol (RTSP) streaming.
You create an on-demand unicast publishing point.

You need to ensure that users from the Internet can access the publishing point on Server1.

Which inbound ports should you allow on the hardware firewall?

A.
TCP 21, UDP 5000, and UDP 5001

B.
TCP 80, TCP 1024, and UDP 500

C.
TCP 443, TCP 8080, and UDP 5000

D.
TCP 554, UDP 5004, and UDP 5005

Explanation:
Delivering a unicast stream

To make sure that your content is available to all client versions that connect to your server, open all ports described in the table for all of the connection protocols that might be used during protocol rollover. When you install Windows Media Services 2008 on a computer that is running Windows Server 2008 or Windows Server 2008 R2, the Windows Media Services program (wmserver.exe) is added as an exception in Windows Firewall to open the default inbound ports for unicast streaming, and manually opening ports in the firewall is not required.
