Catalyst switches take less time to process frames than hubs take.

Catalyst switches decrease the amount of bandwidth available to hosts.

Catalyst switches increase the number of collision domains in the network.

Catalyst switches do not forward broadcasts.

Switches are slower than bridges because they have fewer ports.

A switch is a multiport bridge.

Bridges and switches learn MAC addresses by examining the source MAC address of each frame received.

A bridge forwards a broadcast, but a switch does not.

Hubs do not extend the length of an Ethernet segment.

Hubs do not offer half-duplex connections.

Hubs do not give dedicated bandwidth to each end user.

Hubs do not accept 100Mbps connections.

Yes, this configuration accomplishes the objective.

No, to disable Telnet, you must also enter the command no transport input telnet.

No, SSH requires RSA keys that are 512 bits or less.

No, rather than using the VTY lines, you should be configuring SSH lines.

A security violation has occurred, and the interface has been shut down.

There have been security violations in the past, but at present, there is no device connected to the port.

A MAC address is stuck on the interface and needs to be cleared.

Port security requires at least one configured MAC address to be entered and is presently keeping the interface in the down state.

A default-gateway is not configured on SwitchB.

One of the routers is denying access to the IP subnet of SwitchB from HostA.

HostA is on a different IP subnet than SwitchB.

SwitchB and the Ethernet interface of RouterB are on different IP subnets.

SwitchB and the Ethernet interface of RouterA are on different subnets.

The user is sending too much traffic and is likely saturating the link.

The Ethernet cable length between the host and the server is too long.

The switch is not configured to handle the multicast messages it is receiving.

The keepalive has not been set.

The devices will first transmit a jam signal.

The devices will wait a specific amount of time and then retransmit their data.

The devices will ignore the collision and continue to transmit data.

One device will transmit a specialized beam using the Ethernet cable, which causes the other device to melt.

The switch has experienced a hardware failure.

One or more of the ports on the switch are experiencing a speed or duplex mismatch.

The devices attached to the switch have flapping interfaces.

The switch is currently rebooting.

The interface has an unusually high number of output drops.

The management interface has been moved from VLAN 1.

The management interface is shutdown.

The Catalyst 3550 supports only SSH connections.

The Static MAC addresses had to be input by an administrator; the Dynamic MAC addresses were learned by the switch.

The Static MAC addresses belong to the switch itself; the Dynamic MAC addresses were learned by the switch.

The Static MAC addresses had to be learned by the switch; the Dynamic MAC addresses were input by an administrator.

The Static MAC addresses are reversed duplicates of the Dynamic MAC addresses and were learned by the switch.

The frame is dropped.

The frame is sent out Fa0/3.

The frame is sent out all ports.

The frame is sent out all ports with the exception of the port on which it was received.

Port security is enabled, and ports are limited to a maximum of one violation per port. The first MAC address to transmit data on the port will be the only MAC address allowed. After a second violation has occurred, the interface will shut down.

Port security is enabled, and the port is limited to an access port, which can only be used between switches. Only one upstream switch is allowed to connect to the port. All MAC addresses learned on the port will “stick” to the interface. If more than one upstream switch is attached, the port will shut down.

Port security is enabled, and ports are limited to a maximum of one MAC address each. The first MAC address to transmit data on the port will be the only MAC address allowed. Any other MAC addresses will cause the interface to enter an err-disabled state.

Port security is not enabled because the syntax “switchport port-security on” was not used. All other port-security commands will not take effect until this command is entered.
