No, to disable Telnet, you must also enter the command no transport input telnet. Yes, this configuration accomplishes the objective. Switch(config)# crypto key generate rsa general-keys modulus 1024ĭoes this configuration accomplish your objective?

Switch(config)# username admin password cisco. You have entered the following configuration on one of the switches: You have been asked to convert the management protocol for all the Cisco switches in your network from Telnet to SSH. Hubs do not give dedicated bandwidth to each end user. Hubs do not offer half-duplex connections. Hubs do not extend the length of an Ethernet segment. What do you tell him to justify the purchase of the switches? Your boss asks you to explain why you purchased switches instead of the "cheaper" hubs, because they do the same thing. What command allows you to verify your port security configuration on interface FastEthernet 0/20? Switchport port-security violation shutdown Which of the following configurations accomplishes this objective? If anyone other than the MAC address connects to the port, it should immediately shut down. You want to configure the FastEthernet 0/20 port on your Catalyst switch for port security. What is the effective throughput for each of 24 PCs connecting to a Catalyst switch's FastEthernet ports operating in half-duplex mode? STP monitors and prevents loops in your switched network. STP minimizes broadcasts in your network. The junior network administrator working with you at the time asks you what STP does.

Which of the following is a reason for switching to a Catalyst switch from a hub?Ĭatalyst switches take less time to process frames than hubs take.Ĭatalyst switches decrease the amount of bandwidth available to hosts.Ĭatalyst switches increase the number of collision domains in the network.Ĭatalyst switches do not forward broadcasts. In today's networks, more and more corporations are replacing hubs with switches.
