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

o 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

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

erial 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

o 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

xchanging routing information. The network design requires that R1 r eceive routing updates from R2, but not advertise any routes to R2. Which configuration command sequence will successfully accomplish this task？ （）

A. R1(config)# router eigrp 1 R1(config - router)# passive - interface serial 0

B. R1(config)# access - list 2 0 deny any R1(config)# router eigrp 1 R1(config - router)# distribute - list 20 out serial 0

C. R2(config)# access - list 20 permit any R2(config)# router eigrp 1 R2(config - router)# distribute - list 20 in serial 0

D. R1(config)# access - list 20 permit any R 1(config)# router eigrp 1 R1(config - router)# distribute - list 20 in serial 0

E. R2(config)# access - list 20 deny any R2(config)# router eigrp 1 R2(config - router)# distribute - list 20 out serial 0

F. R2(config)# router eigrp 1 R2(config - router)# passive - interface serial 0

A. Performs switching and routing duties

B. A router that directly connects to a switch

C. A multi-purpose switch fabric used in full mesh environments

D. A switch that directly connects to a router

A. Router R1 will deny the 172.16.1.0/26 route while permitting the 172.16.1.64/27 route to be advertised.

B. Router R1 will advertise both rou tes.

C. Router R1 should be reconfigured with an ACL instead of an ip prefix - list command.

D. Router R1 will deny the 172.16.1.0/27 route while permitting the 172.16.1.0/26 route to be advertised.

ssociated with the subinterface.What command would make this router not use a DR, and dynamically discover OSPF neighbors？（）

A. ip ospf network broadcast

B. ip ospf network non - broadcast

C. ip ospf network point - to - multipoint

D. ip ospf network point - to - multipoint non - broadcast
