考题 Start of repeated scenarioYou are an enterprise desktop support technician for Fabrikam, Inc. Active Directory InformationThe company has a main office and a branch office. The main office hosts all of the companys servers. The main office connects to the branch office by using a WAN link. The network contains a single Active Directory domain that has 500 users. The domain contains three domain controllers and an enterprise root certification authority (CA). All servers run Windows Server 2008 R2. All user accounts are in an organizational unit (OU) named Employees. The computer accounts for all desktop computers are in an OU named Desktops. The computer accounts for all portable computers are in an OU named Laptops. A startup script is deployed to all computers by using Group Policy objects (GPOs). Client ConfigurationsAll client computers run Windows 7 Enterprise. All users have desktop computers. All computers are members of the domain. All desktop computers use wired connections to connect to the network. All portable computers use wireless connections to connect to the network. The wireless network is secured by using EAP-TLS. Company policy states that all client computers must be configured by using DHCP. The company has an internal Web site. The Web site is configured to useSSL encryption and to require client certificates. All company users can access the internal Web site. End of repeated scenario Users in the branch office report slow network performance when they connect to the file shares in the main office. You need to recommend a solution to improve performance when users access the file shares from the branch office. The solution must minimize hardware costs. What should you recommend implementing?()

Which action will accomplish this goal?()A. Declare router B a stub router using the eigrp stub command.B. Use the passive - interface command for interface Serial0/0/0.C. Use a mask with the network command to exclude interface Serial0/0/0.D. Implement a distribute list to exclude the link prefix from the routi ng updates.
