B. Only when a VTP update is received with a higher data VTP revision number will a switch update its VTP database. For more information, see Chapter 3. 50. B. Fifty seconds is the default time for changing from blocking to for- warding state. This is to allow enough time for all switches to update their STP database. For more information on STP, see Chapter 4. 51. A, B, D. The router on a stick is the typical and simplest topology for Multi-Layer Switching (MLS). Multiple switches connected to each other can use MLS if only one switch is connected to the router.
See Chapter 8 for more information. 5. C. The first two are not valid commands. ip mroute cache allows the interface to use fast switching or other types of interface switching for multicast traffic. See Chapter 9 for more information. 6. A, B. When a port is in blocking state, no frames are forwarded. This is used to stop network loops. However, the blocked port will listen for BPDUs received on the port. For more information on STP, see Chapter 4. 7. C. XTAG values are locally significant values that are assigned by the Multi-layer Switching Switch Engine (MLS-SE) to keep track of the Multi-layer Switching Route Processors (MLS-RPs) in the network.
The main challenge for network administrators is to make the campus network run efficiently and effectively. To do this, they must understand current campus networks as well as the new emerging campus networks. Therefore, in this chapter, you will learn about current and future requirements of campus internetworks (the connecting of several campuses). We’ll explain the limitations of traditional campus networks as well as the benefits of the emerging campus designs. You will learn how to choose from among the new generation of Cisco switches to maximize the performance of your networks.
