RIPv2 is in use on the network with no standard policy in place forsummarization. A packet arrives at Certkiller 1 with a destination IP address of208.149.23.91. Given the output that is shown, how will Certkiller 1 process that packet?A. It will forward the packet to 190.171.23.10.B.
It will hold the packet for 21 seconds.C. It will discard the packet because there is no matching route.D. It will hold the packet for 22 seconds.E. It will forward the packet to 190.171.23.12.F. It will forward the packet to 192.168.33.1.Answer: FExplanation:When the packet with the target address 208.149.23.91 reaches Certkiller 1, Certkiller 1searches its routing table but cannot find the routing entry mapping 208.149.23.91, so thedefault route is used:S 0.0.0.0/0 [1/0] via 192.168.33.1The packet is forwarded by Certkiller 1 to 192.168.33.1.Actualtests.com - The Power of Knowing640-802QUESTION 773:Exhibit:Why are two OSPF designated routers identified on Certkiller 3?A.

Two router IDs have the same OSPF priority and are therefore tied for DR election.Answer: AQUESTION 774:Which three statements describe the differences between RIP version 1 and RIP version2? (Choose three.)A. Both RIP version 1 and version 2 support authentication.B. RIP version 1 broadcasts updates whereas RIP version 2 uses multicasts.C.

to provide security on fa0/0 and fa0/1 through the application of an access listActualtests.com - The Power of Knowing640-802B. to translate the internal address of each host on fa0/0 and fa0/1 to a unique external IPaddress for Internet accesC. to allow IP hosts on the Internet to initiate TCP/IP connections to hosts on fa0/0 andfa0/1D. to translate addresses of hosts on the fa0/0 and fa0/1 networks to a single public IPaddress for Internet accessAnswer: DExplanation:The internal network, which is connected by the internal router, uses private IPaddresses. These IP addresses cannot be routed in a public network, so NAT is used.
TwoACLs are defined on the internal router to allow the fa0/0 and fa0/1 networks to invokethe NAT pool for address translation.QUESTION 790:Which protocol provides a method of sharing VLAN configuration information betweenswitches?A.
