How does a router use frames to route data through a network? The router checks the MAC address in the frame, replaces the MAC address of the source with its own MAC address, and sends it to the proper host. The router uses ARP to find the logical address of the receiving host, replaces the MAC address with the logical address, and sends the frame to the proper host. The router checks the MAC address in the frame, uses ARP to compare it to the routing table, then replaces the destination MAC address with its own before sending it to the proper host. The router checks the logical address in the frame, replaces the sender's logical address with the receiver's MAC address, and sends it to the proper host.

The router checks the MAC address in the frame, replaces the MAC address of the source with its own MAC address, and sends it to the proper host.

You are the senior network administrator for a large company. A junior administrator from one of your field offices sent you a router that he thinks is faulty. He says the router always uses default settings and boots to setup mode even though he has verified that startup-config contains the correct values. What is the most likely source of the problem? The NVRAM chip is faulty, preventing the router from loading the configuration. The router configuration register is set to bypass startup configuration. Startup-config in NVRAM is corrupt and must be erased and restored from backup. There is no space available in NVRAM.

The router configuration register is set to bypass startup configuration.

The router reads the LAN segment address contained in the message and consults the appropriate routing table for the protocol, then forwards the message to the appropriate LAN segment.

What role does ARP play in the routing process? If a router does not know a destination device's IP address, it sends an ARP broadcast containing the destination device's MAC address and requesting its IP address. ARP does not play any role in the routing process. Switches use ARP to map IP addresses to MAC addresses in collision domains. If a router knows the MAC and IP address of a destination host, it sends an ARP request to update the other routers' route tables. If a router does not know a destination device's MAC address, it sends an ARP broadcast containing the destination device's IP address and requesting its MAC address.
