Refer to the exhibit. All hosts are in listen mode. Host 1 and Host 4 both transmit data at the same time. How do the hosts respond on the network? (Choose two.)
After the end of the jam signal, a backoff algorithm is invoked.

Refer to the exhibit. 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, because the router is routing traffic between VLANs.
Host A is no longer a member of VLAN 10, because port Fa0/3 has been manually assigned to VLAN 30.
Host A remains a member of VLAN 10, because the switch provides dynamic VLAN assignment for the port.
Host A maintains connectivity to all members of VLAN 10, because it is connected to the same physical network.
Host A is no longer a member of VLAN 10, but because port Fa0/3 was unused, it is now a member of VLAN 1.

Move PC1 to a port on SW2.
Enable pruning for VLAN10 on the VTP server.
Associate PC1 as a member of a new VLAN.

Description: 35691
137. Refer to the exhibit. All switch interfaces are members of the same VLAN. What information is used by Switch1 to determine if incoming frames from the hosts should be forwarded to Router1?
the source address field in the IP header
the destination port number in the TCP header
the destination address field in the Layer 3 header
the destination address field in the Ethernet header

Description: 38674
138. Refer to the exhibit. Switch SWB is not responding to VTP updates from switch SWA. What is a possible cause of the problem?
The VTP revision numbers are different.
The number of existing VLANs is different.
There is a password set on one of the switches.
The enable passwords are not set on the switches.

beacons
association
145. What technique is a security attack that depletes the pool of IP addresses available for legitimate hosts?

146. Refer to the exhibit. All edge ports are configured with the spanning-tree portfast command. Host1 is recently connected to port Fa0/1 on switch SW1. Which statement is true about the status of port Fa0/1?
The port will transition into blocking state.
The port will transition immediately into forwarding state.
The port will transition into blocking state and then immediately into forwarding state.
The port will transition into blocking state and immediately transition through the listening and learning states.

Spanning Tree Protocol will guarantee a loop free Layer 2 topology.Spanning Tree Protocol guarantees the shortest path to destination networks.
The switch with the highest priority will be assigned the lowest BID in the root election.
The first step in the spanning-tree election process is to determine the root port.
To select designated ports, the spanning-tree algorithm must determine the longest contiguous path from the root bridge.

  3. I am having exam next week. Are you sure the paper is going to have questions from this set itself?

  4. I am having a exam next week too, but not ALL questions will be from here, some will be from the chapters itself or the final practice exam. Looking back at this, it is mostly VTP and trunking, and finding out errors, seems to be easier than the previous 2 CCNA's.
