Your company office network includes a file server that has Windows Server 2008 R2 installed and client computers that have Windows 7 Enterprise installed. The computers are members of an Active Directory domain. The file server has the BranchCache feature installed.
The client computers have a third-party firewall application installed.
You configure BranchCache on all computers to run in Distributed Cache mode.
You need to ensure that the client computers can access all cached files.
What should you do?
A. Configure firewall exception rules for multicast traffic, inbound and outbound traffic for local UDP port 3702, and inbound and outbound traffic for local TCP port 80.
B. Check permissions.
C. Configure firewall exception rules for inbound and outbound traffic for local TCP port 80 and for inbound and outbound traffic for local TCP port 8443
D. Create a Group Policy object and enable the Set BranchCache Hosted Cache mode policy.
E. Run the Netsh branchcache set service mode=HOSTEDSERVER clientauthentication=NONE command.
F. Run the netsh branchcache set service mode=HOSTEDCLIENT command.
G. Run the netsh branchcache set service mode=DISTRIBUTED command
H. Create a Group policy object and configure the Set percetage of disk space used for client computer cache option.
I. Create a Group policy that sets Hash Publication for Branchcache as disabled.
Correct Answer: A

Explanation:
Configuring Windows 7 as a BranchCache client involves enabling BranchCache, selecting either Hosted Cache mode or Distributed Cache mode, and then configuring the client firewall to allow BranchCache traffic.
You can configure BranchCache either using Group Policy or by using the Netsh command-line utility. The firewall rules that you configure depend on whether you are using Hosted Cache or Distributed Cache mode.
You can use predefined firewall rules or manually create them based on protocol and port. The required firewall rules are as follows:
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. You can create this rule using Windows Firewall With Advanced Security.
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.
You need to configure the firewall rules only when you configure BranchCache using Group Policy. When you configure BranchCache using Netsh, the appropriate firewall rules are set up automatically.
