1. All network switches require substantial configuration before they can be put into operation in a network.
Network Switches in Depth
2. More VLANs mean fewer logical networks, so the network is less complex.
3. Routers can be used to control network access by inspecting the source and destination address information
of packets.
4. A distance-vector protocol sends updates to its neighbors that include the contents of its routing table.

9. Which switching method reads a minimum of 64 bytes of an Ethernet frame before forwarding the frame?
10. You have four switches, A, B, C, and D. Switch A is connected to Switch C and Switch B is connected to
Switch D. Furthermore, Switch A and B are connected and Switch C and D are connected. One of the
connections is in blocking mode. What protocol must be running on the switches?
11. Which of the following is NOT a function that would be found in a managed switch?
the ability to stop switching loops using STP

the creation of VLANS to logically separate resources
to limit access to the network by enabling security on individual ports
12. Your colleagues are discussing the operation of a device in which packets are routed between VLANs on
the device rather than having to exit the device to be routed. What type of device are they most likely
discussing?
13. When a router’s interface is configured to connect with a switch trunk port to route packets between
VLANs, what is this called?
14. In which type of routing protocol is a router’s routing table copied to neighboring routers to share
internetwork information?

local drive?
advanced configuration power management interface
preboot execution environment

27. A switch that is configured to use the Spanning Tree Protocol will place a port in ____________ mode if
sending traffic to it may cause a switching loop.
28. A router’s final task when handling a packet is to send the packet on to its next and possibly final
destination; this is referred to as packet ____________.
29. One type of security for wireless networks involves entering a list of the MAC addresses for the devices that
are allowed to access the network and excluding all others. This is called MAC ____________.

30. A ____________ is used to make connections between the network interface card and the other vital
components of the computer, such as the central processing unit.

36. configured to carry VLAN traffic
37. routing protocol category in which the routing protocol is used to exchange routing information between
autonomous systems
38. sends the status of all its interface links to all other routers in the internetwork
39. value that tells routers the best path to the destination network
40. routing protocol category in which the routing protocol is used to exchange routing information within an
autonomous system
41. Briefly describe the three types of switching methods.
Cut-through switching is the fastest; it reads the destination MAC address and sends the
frame out. Store-and-forward switching is the slowest; it stores the entire message and then
sends it to the correct port. Fragment-free switching is the middle man; it reads enough to
make sure the packet is not fragmented and then sends it out.
42. What does the Spanning Tree Protocol do?
The Spanning Tree Protocol is used to detect whether there is a possibility of a switching
loop caused by redundant paths. If a loop is possible, it places one of the ports in blocking
mode to prevent it.

50. What is BGP and how is it used?
BGP is classified as an exterior gateway protocol used to route packets between autonomous
systems. BGP is a path-vector routing protocol, which analyzes the characteristics of all
autonomous systems lying in the path between the router and each destination network so
that it can form a nonlooping routing topology. BGP is used between ISPs, but it can also be
used on border routers of large organizations’ networks.
