第2题：

A company has a Frame Relay WAN with one central - site router and 100 branch office routers. A partial mesh of PVCs exists: one PVC between the central site and each of the 100 branch routers. Which of the following could be true about the number of EIGRP neighbor ships?（）

• A、A partial mesh totaling 100: one between the central - site router and each of the 100 branches.
• B、A full mesh  -  (101 * 100) / 2 = 5050 - One neighborship between each pair of routers.
• C、101 - One between each router (including the central site) a nd its nearby PE router.
• D、None of the answers is correct.

第4题：

Your company has a main office and ten branch offices.  Your network consists of a single domain Active Directory forest. An Active Directory site exists for each office.  The main office contains five domain controllers that run Windows Server 2008 （x64）.  Each branch office contains one read-only domain controller （RODC） that runs Windows Server 2008（x86）.  All domain controllers are configured as global catalog servers. You plan to deploy one Exchange Server 2010 server in each site.  You need to recommend changes to Active Directory to support the planned deployment.  The solution must ensure that Exchange servers in each branch-office site connect to their local domain controllers.  What should you recommend？（）

• A、Implement a DNS zone for each office.
• B、Change all RODCs to Windows Server 2008 （x64） RODCs.
• C、Implement a writable domain controller in each branch office.
• D、Disable site link bridging for the forest and configure Exchange-specific costs.

第5题：

What two choices can you make when redundancy is required from a branch office to a regional office？ （）

• A、 multiple Frame Relay PVCs
• B、 dual Wan links to the regional office
• C、 dual Wan links to another branch office
• D、 single links - one to the regional office and one to another branch office

第6题：

A company has a Frame Relay WAN with one central - site router and 100 branch office routers. A partial mesh of PVCs exists: one PVC between the central site and each of t he 100 branch routers. All routers use point - to - point subinterfaces and one subnet per PVC. Which of the following is true about OSPF in this design?（）

• A、The central site router has 100 fully adjacent neighborships with the 100 branches
• B、The central  site router has neighborships with all branch routers, but fully adjacent neighbors with only two branches
• C、The central site router has a neighborship with the Frame Relay switcH
• D、None of the other answers is correct

第7题：

Customer X has a hub-and-spoke Frame Relay network， with a central office and two branch offices （RemoteA and RemoteB）. Each location has only one physical link to the Frame Relay cloud and RemoteB has a router that is not a Cisco router. Since the installation， there is no connectivity between RemoteB and the central office. What is a possible solution to this issue？ （）

• A、 Because Frame Relay IETF encapsulation is only configurable at interface level， you must use IETF encapsulation on all routers.
• B、 This is not a possible scenario. A dedicated Frame Relay link to RemoteB is mandatory at the central office.
• C、 The router at RemoteB must be replaced by a Cisco router.
• D、 Use Frame Relay IETF encapsulation on a per-VC basis on the central office router.
• E、 There is a problem in the Frame Relay cloud， because Cisco routers are compatible with IETF Frame Relay.

第9题：

You are designing an Active Directory site infrastructure to meet the bussiness and technical requirements. What should you do?（）

• A、Create one site for each office and each local bank.
• B、Create one site for all offices. Create one site for all local banks.
• C、Create one site for Amsterdam. Create one site for all branch office and all local banks.
• D、Create one site for Amsterdam. Create one site for the Utercht brach office. Create one site for that Hague branch office. Place half the local banks in the utercht site and half the local banks in the Hague site.
• E、Create one site for Amsterdam. Create one site for the Utercht brach office. Create one site for each local bank that has more than 50 users. Place all the other local banks in the Amsterdam Site.

第10题：

Your company has a main office and 20 branch offices.Each office contains an Exchange Server 2010 Mailbox server and an Exchange Server 2010 Hub Transport server. Each office is configured as a separate Active Directory site.Each branch office site has one IP site link that connects to the main office site.You need to ensure that e-mail sent between offices is routed through the Hub Transport servers in the main office. What should you do？（）

• A、From the Exchange Management Shell， modify the Exchange-specific site link costs.
• B、From the Exchange Management Shell， configure the main office site as a hub site.
• C、From Active Directory Sites and Services， modify the site link costs.
