Unnecessary flooding will slow network performance. The MAC table will fill with unused addresses.Īddress conflicts will cause retransmission errors. What is a likely result of this decision? In an attempt to improve switch performance, a network administrator changes the MAC aging time to ten seconds. The network administrator determines that VLAN information is not propagating to SW3. A new switch, SW3, has been added to the network. In the implementation of PVST+ in a specific VLAN where all switches have default spanning tree priorities, which spanning-tree command setting could be assigned to force one of the Catalyst switches to become and remain the root bridge? Portfast can be used to increase the allowable switched network diameter because it disables the forward delay and maximum age timers. Using lower bandwidth connections between switches will allow STP to have a larger network diameter.

Layer 2 root elections should be optimized by adjusting BPDU timers to match network diameter. STP diameters are restricted by convergence times. Which statement about STP network diameter is correct? Take Assessment - ESwitching Final Exam - CCNA Exploration: LAN Switching and Wireless (Version 4.0) The switch allows remote connections only after a new RSA key pair is generated. The switch is no longer able to make SSH connections as an SSH client. The switch defaults to allowing Telnet connections only. What happens when the crypto key zeroize rsa command is entered on a switch configured with the transport input ssh command on the vty lines?

A network administrator needs to download a previously saved configuration file from the TFTP server to Switch1.
