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 retrievedfrom
the branch office server.
Which firewall rule should you enable on the clientcomputers?

A.
BranchCache – Content Retrieval (Uses HTTP)

B.
BranchCache – Hosted Cache Server (Uses HTTPS)

C.
BranchCache – Peer Discovery (Uses WSD)

D.
File and Printer Sharing

Configure domain member client distributed cache mode firewall rules
When you configure BranchCache in distributed cachemode, 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 vailable, 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 DistributedCache
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.
