ICND1 Practice Test

A network technician is configuring port security on a LAN switch interface. The security policy requires host MAC addresses to be learned dynamically, stored in the address table, and saved to the switch running configuration. Which command does the technician need to add to the following configuration to implement this policy?

• Switch(config-if)# switchport port-security maximum 40

• Switch(config-if)# switchport port-security mac-address

• Switch(config-if)# switchport port-security mac-address sticky

• Switch(config-if)# switchport port-security mac-address 000B.FCFF.E880

On which switch interface would an administrator configure an IP address so that the switch can be managed remotely?

• FastEthernet0/1

• VLAN 1

• vty 0

• console 0

Refer to the exhibit.

A ping to PC3 is issued from PC0, PC1, and PC2 in this exact order. Which MAC addresses will be contained in the S1 MAC address table that is associated with the Fa0/1 port?

• just PC0 and PC1 MAC addresses

• just the PC0 MAC address

• PC0, PC1, and PC2 MAC addresses

• just the PC1 MAC address

• just the PC2 MAC address​

Which feature on a Cisco router permits the forwarding of traffic for which there is no specific route?

• next-hop

• gateway of last resort

• route source

• outgoing interface

Refer to the exhibit.

Inter-VLAN communication between VLAN 10, VLAN 20, and VLAN 30 is not successful. What is the problem?

• The access interfaces do not have IP addresses and each should be configured with an IP address.

• The switch interface FastEthernet0/1 is configured as an access interface and should be configured as a trunk interface.

• The switch interface FastEthernet0/1 is configured to not negotiate and should be configured to negotiate.​

• The switch interfaces FastEthernet0/2, FastEthernet0/3, and FastEthernet0/4 are configured to not negotiate and should be configured to negotiate.​

Which two issues might cause excessive runt and giant frames in an Ethernet network? (Choose two.)

• native VLAN mismatch

• damaged cable connector

• a malfunctioning NIC

• excessive collisions

• using the incorrect cable type

How will a router handle static routing differently if Cisco Express Forwarding is disabled?

• It will not perform recursive lookups.

• Serial point-to-point interfaces will require fully specified static routes to avoid routing inconsistencies.

• Ethernet multiaccess interfaces will require fully specified static routes to avoid routing inconsistencies.

• Static routes that use an exit interface will be unnecessary.

Refer to the exhibit.

A network administrator is reviewing port and VLAN assignments on switch S2 and notices that interfaces Gi0/1 and Gi0/2 are not included in the output. Why would the interfaces be missing from the output?

• There is a native VLAN mismatch between the switches.

• There is no media connected to the interfaces.

• They are administratively shut down.

• They are configured as trunk interfaces.

Which address type is not supported in IPv6?

• private

• multicast

• unicast

• broadcast

Refer to the exhibit.

A technician is programming switch SW3 to manage voice and data traffic through port Fa0/20. What, if anything, is wrong with the configuration?

• There is nothing wrong with the configuration.

• Interface Fa0/20 can only have one VLAN assigned.

• The mls qos trust cos command should reference VLAN 35.

• The command used to assign the voice VLAN to the switch port is incorrect.
