You are the network administrator for Your network consists of a single Active Directory domain named All network servers run Windows Server 2003. All client computers run Windows XP Professional. TK1 is your global catalog server. TK2 runs Software Update Services (SUS). The Set Options console on TK2 uses all default settings. You configure the client computers to access the service on TK1 and TK2. Three months later, Microsoft releases a critical security update for Windows XP Professional. From a test client computer, you use Windows Update to download the update. You test the update and receive no error messages. Now you need to deploy the update to all client computers as quickly as possible. You must ensure that the update is not deployed to any servers. Which two actions should you perform? （）(Each correct answer presents part of the solution. Choose two)

• A、On TK1, configure the Default Domain Group Policy object (GPO) to distribute the security update.
• B、On TK1, initiate replication.
• C、On TK2, initiate synchronization.
• D、On TK2, approve the security update.

A new router, named TK1, is being installed. You wish to add this router to your existing OSPF network. In doing so, you configure the following: TK1(config)# router ospf 1 TK1(config-router)# network 10.10.10.0 255.255.255.0 area 0 After making this change, you notice that the networks attached to TK1 are not being learned by the other OSPF routers. What could be the cause of this?（）

• A、The AS is not correctly configured
• B、The network subnet mask is incorrectly configured
• C、The network wildcard mask is configured incorrectly
• D、The network number is not correctly configured
• E、The process id is configured incorrectly
• F、None of the above

The Testking network is utilizing RIP as the IP routing protocol. Router TK1 learns how to reach the same destination via 6 different paths. All paths have the same metric and administrative distance. With all routers using the default operation,which of the paths will be chosen to reach the destination?（）

• A、Only the first two paths that are learned.
• B、Four of the paths.
• C、All six routes in a routed robin fashion.
• D、The oldest two paths in the routing table.
• E、The first path learned to the destination network.

第17题：

Your network has a mixture of Fast Ethernet and Gigabit Ethernet links. What needs t o be done to ensure optimal data routing when using OSPF?（）

• A、Nothing. OSPF will determine the most optimal path for routing data by default.
• B、Adjust the hello and dead timers for more rapid detection of link failures.
• C、Increase the reference - bandw idth used to calculate the interface default metrics, on all routers in your network.
• D、Set the priority values on every broadcast interface to ensure that the designated and backup designated routers are the routers with the most processor and memory  resources.
