Your network has a main office and a branch office.
The branch office has five client computers that run Windows 7 and a server that runs Windows Server 2008 R2. The branch office server is enabled for BranchCache.
You need to configure Windows Firewall on each client computer so that cached content can be retrieved from the branch office server.
Which firewall rule should you enable on the client computers?
A. BranchCache - Content Retrieval (Uses HTTP)
B. BranchCache - Hosted Cache Server (Uses HTTPS)
C. BranchCache - Peer Discovery (Uses WSD)
D. File and Printer Sharing
Correct Answer: A

Explanation:
Configure domain member client distributed cache mode firewall rules When you configure BranchCache in distributed cache mode, BranchCache client computers use the Hypertext Transfer Protocol (HTTP) for data transfer with other client computers. BranchCache client computers also use the Web Services Dynamic Discovery (WS-Discovery) protocol when they attempt to discover content on client cache servers. You can use this procedure to configure client firewall exceptions to allow incoming HTTP and WS-Discovery traffic on client computers that are configured for distributed cache mode.
The BranchCache Content Retrieval (Uses HTTP) predefined rule. If this rule is not available, create rules that allow inbound and outbound traffic on TCP port 80. This rule is required for both Hosted Cache and Distributed Cache mode.
The BranchCache Peer-Discovery (Uses WSD) predefined rule. If this rule is not available, create rules that allow inbound and outbound traffic on UDP port 3702. This rule is only required when using Distributed Cache mode.
The BranchCache Hosted Cache Client (HTTPS-Out) predefined rule. It this rule is not available, configure a rule that allows outbound traffic on TCP port 443. This rule is required only when using Hosted Cache mode.
