第8题：

You are a network administrator for your company. The network consists of a single Active Directory domain. All servers run Windows Server 2003. The company’s main office is in Barcelona， and it has branch offices in Paris and London. The company has no immediate plans to expand or relocate the offices.   The company wants to connect the office networks by using a frame relay WAN connection and Routing and Remote Access servers that are configured with frame relay WAN adapters. Computers in each office will be configured to use the local Routing and Remote Access server as a default gateway. You are planning the routing configuration for the Routing and Remote Access servers.   You need to allow computers in Barcelona， Paris， and London to connect to computers in any office. You want to minimize routing traffic on the WAN connection.   What should you do？  （）

• A、 At each office， add the OSPF routing protocol to Routing and Remote Access， add the WAN adapter to the OSPF routing protocol， and deploy OSPF as a single-area internetwork.
• B、 At each office， add the RIP version 2 routing protocol to Routing and Remote Access， and configure the WAN adapter to use RIP version 2. Configure the outgoing packet protocol as RIP version 2 broadcast and the incoming packet protocol as RIP version 1 and 2.
• C、 At each office， add the RIP version 2 routing protocol to Routing and Remote Access， and configure the WAN adapter to use RIP version 2. Configure the outgoing packet protocol as RIP version 2 multicast and the incoming packet protocol as RIP version 2 only.
• D、 At each office， configure the Routing and Remote Access server with static routes to the local networks at the other two offices.
