Refer to the exhibit. Layer 2 root elections should be optimized by adjusting BPDU timers to match network diameter. How can this problem be fixed? Reposition the APs so that each area of signal strength overlaps the neighbor by at least 10-15%.net/ccna3-final-exam-b-latest/ 25/11/2010 . Using lower bandwidth connections between switches will allow STP to have a larger network diameter.Refer to the exhibit. 7. Portfast can be used to increase the allowable switched network diameter because it disables the forward delay and maximum age timers. 8. A new host needs to be connected to VLAN 3.168.In setting up a wireless infrastructure network. The network administrator wants to configure Switch1 to allow SSH connections and prohibit Telnet connections.Refer to the exhibit.Which statement about STP network diameter is correct?

Host A maintains connectivity to all members of VLAN 10. subnet mask.) Each subinterface should be configured with its own IP address.net/ccna3-final-exam-b-latest/ 25/11/2010 . Hosts 1 and 4 are operating full duplex so no collision will exist. The physical interface of the router must be connected to a trunk link on the adjacent switch. but because port Fa0/3 was unused. All hosts are in listen mode. 15. because it is connected to the same physical network. 13. Hosts 1 and 4 are assigned shorter backoff values to provide them priority to access the media.Refer to the exhibit. and unique VLAN assignment.What are two requirements for configuring inter-VLAN routing using the router-on-a-stick model? (Choose two.Refer to the exhibit. Host 1 and Host 4 both transmit data at the same time. Reconfigure the fa0/1 interface on switch SW1 with a static trunk configuration.

If a host has data to transmit after the backoff period of that host. 14. Host A is no longer a member of VLAN 10. because the router is routing traffic between VLANs. a backoff algorithm is invoked. The hub will block the port connected to Host 4 to prevent a collision. because port Fa0/3 has been manually assigned to VLAN 30.) After the end of the jam signal. Configure both switches in VTP transparent mode to allow them to share VLAN information. Host A remains a member of VLAN 10. http://neversummer.

What would happen if the network administrator moved the network cable of Host A from interface Fa0/1 to Fa0/3 on switch SW1? Host A remains a member of VLAN 10. What should be done to fix the problem? Introduce a Layer 3 device in the topology. it is now a member of VLAN 1. How do the hosts respond on the network? (Choose two. because the switch provides dynamic VLAN assignment for the port.
