Troubleshoot Static and Default Routes

Which sequence correctly identifies the order of the steps that a router will perform when it receives a packet on an Ethernet interface?

• 1. The router examines the destination MAC address. 2. The router identifies the Ethernet Type field. 3. The router de-encapsulates the Ethernet frame. 4. The router examines the destination IP address.

• 1. The router examines the destination IP address. 2. The router identifies the Ethernet Type field. 3. The router examines the destination MAC address. 4. The router de-encapsulates the Ethernet frame.

• 1. The router de-encapsulates the Ethernet frame. 2. The router examines the destination MAC address. 3. The router identifies the Ethernet Type field. 4. The router examines the destination IP address.

• 1. The router examines the destination MAC address. 2. The router identifies the Ethernet Type field. 3. The router examines the destination IP address. 4. The router de-encapsulates the Ethernet frame.

Which three IOS troubleshooting commands can help to isolate problems with a static route? (Choose three.)

• show version

• show ip interface brief

• ping

• show ip route

What command would a network administrator use to verify that the exit interface is up?

• show ip route

• show ip interface brief

• show ip protocols

• tracert

What should an administrator do to remove a static route from the routing table when the destination network no longer exists?

• Change the routing metric for that route.

• Nothing. The static route will go away on its own.

• Change the administrative distance for that route.

• Remove the route using the no ip route command.

What describes the sequence of processes executed by a router when it receives a packet from a host?

• It selects the path and forwards it toward the destination host.

• It de-encapsulates the packet, selects the appropriate path, and encapsulates the packet to forward it toward the destination host.

• It receives the packet and forwards it directly to the destination host.

• It de-encapsulates the packet and forwards it toward the destination host.

What is the purpose of the show cdp neighbor command?

• To verify the network addresses that are attached to the network devices.

• To check the connectivity of PCs that are connected to the network devices.

• To check the networks that are advertised by the neighboring routers.

• To obtain information about directly connected Cisco devices.

What two router commands would an administrator use to determine if the exit interface was up and the next hop address is available? (Choose two.)

• tracert

• show ip protocols

• ping

• show ip route

What should the administrator do if the command ip route 192.168.10.64 255.255.255.192 serial0/0/1 is not in the routing table?

• Verify that the 192.168.10.64 network is active within the network infrastructure.

• Re-enter the command using a network number rather than a usable IP address.

• Verify that the serial 0/0/1 interface is active and available.

• Re-enter the command using the correct mask.

What will a router do if it does not have a default route configured and a packet needs to be forwarded to a destination network that is not listed in the routing table?

• Send it back to the source.

• Forward it to another router.

• Send it to the default gateway.

• Drop it.

What does the letter C mean next to an entry in the output of the show ip route command?

• It identifies a network that is learned through EIGRP.

• It identifies a network that is directly connected to the router.

• It identifies a network that is learned through OSPF.

• It identifies a network that is a static route.
