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?（）

Router R1 sits at an Enterprise branch office, using both the Internet and a leased line to another Enterprise router for its two connectivity options back into the rest of the Enterprise network. The engineer planning for this branch decided to use the leased line for all Enterprise traffic, unless it fails, in which case the Internet connection should be used to pass traffic to the Enterprise. Which of the following is most likely to be useful on the branch router?（）
- A、IPsec tunnel
- B、GRE tunnel
- C、Floating stati c route
- D、An IGP
正确答案:A,C
第5题：
Enterprise Router R1, in ASN 1, connects to ISP Router I1, ASN 2, using eBGP. There are two parallel serial links between the two rou ters. The implementation plan calls for each router to base their BGP TCP connection on their respective loopback1 interfaces, with IP addresses 1.1.1.1 and 2.2.2.2, respectively. Which of the following commands would not be part of a working eBGP confi guration on Router R1?（）
- A、router bgp 1
- B、neighbor 2.2.2.2 remote- as 2
- C、neighbor 2.2.2.2 update - source loopback1
- D、neighbor 2.2.2.2 multihop 2
正确答案:D
第6题：
A company uses Routers R1 and R2 to connect to ISP1 and ISP2, respectively, with Routers I1 and I2 used at th e ISPs. R1 peers with I1 and R2; R2 peers with I2 and R1. R1 and R2 do not share a common subnet, relying on other routers internal to the Enterprise for IP connectivity between the two routers.Which of the following could be used to prevent potential routing loops in this design?（）
A. Using an iBGP mesh inside the Enterprise core
B. Configuring default routes in the Enterprise pointing to both R1 and R2
C. Redistributing BGP routes into the Enterprise IGP
D. Tunneling the packets for the i BGP connection between R1 and R2
第7题：
Enterprise Router R1, in ASN 1, connects to ISP Router I1, ASN 2, using eBGP. The single serial link b etween the two routers uses IP addresses 10.1.1.1 and 10.1.1.2, respectively. Both routers use their S0/0 interfaces for this link. Which of the following commands would be needed on R1 to configure eBGP?（）
- A、router bgp 2
- B、router bgp 1
- C、neighbor 10.1 .1.2 remote - as 2
- D、neighbor 10.1.1.2 Update - source 10.1.1.1
- E、neighbor 10.1.1.2 Update- source S0/0
正确答案:B,C
第8题：
Router R1, a branch router, connects to the Internet using DSL. Some traffic flows through a GRE and IPsec tunnel, over the DSL connection, destined for an Enterprise network.Which of the following answers best describes the router‘s logic that tells the router, for a given packet, to apply GRE encapsulation to the packet?（）
A. When the packet received on the LAN interface is permitted by the ACL listed on the tunnel greacl command under the incoming interface
B. When routing the packet, matching a route whose outgoing interface is the GRE tunnel interface
C. When routing the packet, matching a route whose outgoing interface is the IPsec tunnel interface
D. When permitted by an ACL that was referenced in the associated crypto map
第9题：
Router R1, a branch router, connects to the Internet using DSL. Some traffic flows through a GRE and IPsec tunnel, over the DSL connection, and into the core of an Enterprise network. The branch also allows local hosts to communicate directly with public sites in th e Internet over this same DSL connection. Which of the following answers defines how the branch NAT config avoids performing NAT for the Enterprise directed traffic but does perform NAT for the Internet - directed traffic?（）
- A、By not enabling NAT on the I Psec tunnel interface
- B、By not enabling NAT on the GRE tunnel interface
- C、By configuring the NAT - referenced ACL to not permit the Enterprise traffic
- D、By asking the ISP to perform NAT in the cloud
正确答案:C
第10题：
Enterprise Router R1 connects an Enterprise to the Internet. R1 needs to create and advertise a default route into the Enterprise using EIGRP. The engineer creating the implementation plan has chosen to base this default route on the ip route command, rather than using i p default - network. Which of the following is not a useful step with this style of default route configuration?（）
- A、Create the default route on R1 using the ip route 0.0.0.0 0.0.0.0 outgoinginterface command.
- B、Redistribute the statically configured defa ult route.
- C、Disable auto - summary.
- D、Configure the network 0.0.0.0 command.
- E、Ensure R1 has no manually configured summary routes using the ip summary- address eigrp command.
