Decapsulates the Layer 3 packet by stripping off the Layer 2 frame header
Uses the destination MAC Address in the IP Header to look up the next-hop address in the routing table
Uses the destination IP Address in the IP header to look up the next-hop address in the routing table

The subnet mask of host 2 is incorrect.
Host 1 and host 2 are on different networks.
The switch needs an IP address that is not configured.
The router LAN interface and host 1 are on different networks.
The IP address of host 1 is on a different network than is the LAN interface of the router.

The startup sequence will reset.
The router will prompt the user for a response to enter setup mode.
The startup sequence will halt until a valid configuration file is acquired.
The router will generate a default configuration file based on the last valid configuration.
The router will monitor local traffic to determine routing protocol configuration requirements.
RAM permanently stores the configuration file used during the boot sequence.
ROM contains diagnostics executed on hardware modules.
NVRAM stores a backup copy of the IOS used during the boot sequence.
Flash memory does not lose its contents during a reboot.
ROM contains the most current and most complete version of the IOS.
This router only has two interfaces.
The router interfaces are not operational yet.
This router is configured to forward packets to remote networks.
The FastEthernet0/0 and Serial0/0/0 interfaces of this router were configured with an IP address and the no shutdown command.
An IP packet received by this router with a destination address of 198.18.9.1 will be forwarded out of the Serial0/0/0 interface.
Load balancing occurs when a router sends the same packet to different destination networks.
Load balancing occurs when the same number of packets are sent over static and dynamic routes.
Load balancing allows a router to forward packets over multiple paths to the same destination network.
Unequal cost load balancing is supported by EIGRP.
If multiple paths with different metrics to a destinations exist, the router cannot support load balancing.
The destination networks do not exist.
The IP addresses on the router interfaces must be configured as network addresses and not host addresses.
The interfaces must be enabled with the no shutdown command.
Each interface must be configured with the clock rate command.
If RouterC receives a packet that is destined for 10.5.1.1, it will be forwarded out interface Fa0/0.
If RouterA receives a packet that is destined for 192.168.3.146, it will be forwarded out interface S0/0/1.
If RouterB receives a packet that is destined for 10.5.27.15, it will be forwarded out interface S0/0/1.
If RouterB receives a packet that is destined for 172.20.255.1, it will be forwarded out interface S0/0/0.
If RouterC receives a packet that is destined for 188.8.131.52, it will be forwarded out interface S0/0/1.
