Chapter 5

5.1.10 1 - Which of the following describes the role of Access Switches and how they are implemented in the design of a local area network on a university or corporate campus? (Select three.) - Communicate with each other through distribution switches. AND Connected to distribution switches using one or more ports or uplinks. AND Give end users access to the local area network. 2 - An Ethernet frame has just arrived on a switch port. The switch examines the destination MAC address of the frame. It is a unicast address, but no mapping exists in the CAM table for the destination address, no Vlans - The switch sends a copy of the frame to all connected devices on all ports. 3 - Device B sends a frame to Device A on the network shown. The switch has an entry in its CAM table for Device A in its database, but not for Device B - The switch records the address and port for Device B in its database. It sends the frame out port Fa0/1. 4 - Wrk1 sends a frame addressed to Wrk5. What will the switch do with the frame – Drop the frame AND Not record the location of any device 5 - How many collision domains exist on the network shown – 4 6 - You administer a network that uses bridges to connect network segments. The network is currently suffering from serious broadcast storms - Replace the bridges with routers 7 - Which of the following are advantages of using bridges to segment LAN traffic - Bridges can link network segments that use different physical media (as long as they have the same architecture). AND Bridges create separate collision domains. 8 - Which connectivity device would best reduce the number of collisions and prepare for future growth – Switch 9 - Which frame processing method causes a switch to wait until the first 64 bytes of the frame have been received before forwarding the frame to the destination device – fragment-free 10 - Which of the following are true of store-and-forward switches - Frames with errors are dropped AND Frames are checked for errors before being forwarded AND Latency is greater than with cut-through switches 5.2.5 In this lab, your task is to:  Configure the switch port Fa0/6 to use 10 Mbps.  Configure the switch port Fa0/7 to use half-duplex communications.  Make sure that ports Fa0/6 and Fa0/7 are enabled and can be used even though you haven't connected devices to those ports yet.  Disable the unused interfaces. o Fa0/4 and Fa0/5 o Fa0/8 through Fa0/23

AND The switch must be configured with a valid IP address and default gateway. 3 - During the initial setup of a new switch, which of the following configuration tasks should be performed? - Set the default gateway for remote management. AND Set passwords for the console, virtual terminal (TTY) ,and enable mode. AND Set an IP address for remote management.

4 – 5 - What is one difference between the VLAN interface configuration and config-vlan? - VLAN interface configuration mode is used to configure the switch IP address. 6 - You have a workstation connected to a small branch network using a single switch. The network does not have any routers and is not connected to the internet. What are the minimum configuration parameters required on the workstation to be able to communicate with all hosts on the network? – IP Address and subnet mask 7 - Which address would you use for the default gateway address? - The IP address assigned to Fa0/0 on Router1. 8 – 9 - Which command(s) would you use to configure a default-gateway on a Catalyst 2950XL switch? - Switch(config)#ip default-gateway 192.168.10.1
