Chapter 5 and 8 Study Set

A packet arrives at a router interface. The router goes through a series of steps to determine where the packet should be forwarded. Place the steps of the router forwarding process in the correct order.

1. Examine Packet Header 2. Determine Destination Network 3. Place Route in Routing Table 4. Identify exit interface to destination from route entry 5. Move packet to forwarding interface

Which statement about host forwarding decisions is true? A A remote destination host is on the same local network as the sending host B. Local Hosts can reach each other without the need of a router C. A host cannot ping itself D. Routing is enabled on switches to discover the best path to a destination.

B. Local Hosts can reach each other without the need of a router.

Destination IP Address

What are two functions that are provided by the network layer?

Directing data to destinations and providing end devices with a network identifier

When transporting data from real time applications such a streaming audio and video, what field in an IPv6 header can be used to inform routers and switches to maintain the same path for packets?

Flow Label

Which Feature on a Cisco Router allows traffic to be sent without a route?

Gateway of Last Resort

What's true about an IPv6 header?

It contains 8 fields

How does the network layer use the MTU value?

Within a production network, what's the purpose of configuring a switch with a default gateway address?

The default gateway address is used to forward packets originating from the switch to remote networks.
