administrative distance
During the process of encapsulation, how does the PC determine if the packet is destined for a host on a remote network?
by performing the AND operation on the destination IP address and its own subnet mask
When a router receives a packet, what information must be examined in order for the packet to be forwarded to a remote destination?
destination IP address
Which feature on a Cisco router permits the forwarding of traffic for which there is no specific route?
gateway of last resort

no shutdown
R1 S0/0/0 ------ S0/0/0 R1 G0/0 | | G0/0 | | | | {Switch] [Switch] | | | | PC1 PC2 192.168.10.8/24 192.168.11.5/24 Refer to the exhibit. If PC1 is sending a packet to PC2 and routing has been configured between the two routers, what will R1 do with the Ethernet frame header attached by PC1?
remove the Ethernet header and configure a new Layer 2 header before sending it out S0/0/0
Open the PT Activity. Perform the tasks in the activity instructions and then answer the question. When PC0 pings the web server, which MAC address is the source MAC address in the frame from R2 to the web server?
0001.C972.4202
SERVER B MAC: 00B0857F0A0B IPv4: 192.168.10.16 (cloud) R1 MAC: 000B857F86B0 IPv4: 192.168.10.1 S1: MAC: 000B85D0BBF7 IPv4: 192.168.11.1 PC A MAC: 000B857F4700 IPv4: 192.168.12.10 Refer to the exhibit. PC A sends a request to Server B. What IPv4 address is used in the destination filed in the packet as the packet leaves PC A?
192.168.12.16

Refer to the exhibit. A network administrator issues the show ipv6 route command on R1. What two conclusions can be drawn from the routing table? (Choose two.)
R1 does not know a route to any remote networks The interface Fa0/1 is configured with IPv6 address 2001:DB8:ACAD:A::12

ROM contains diagnostics executed on hardware modules. Flash memory does not lose its contents during a reboot.

However, when the administrator issues the command show ip route, the routing table does not show the directly connected network. What is the possible cause of the problem?
The interface fa0/0 has not been activated
Which two statements describe static routes? (Choose two.)
They require manual reconfiguration to accommodate network changes. They are identified in the routing table with the prefix S.
