CCNA 3 Final

Which routing protocol is able to scale for large networks and utilizes non-backbone areas for expansion?

• EIGRP
• BGP
• OSPF
• RIPv2

In the Cisco hierarchical design model, which layer is more likely to have a fixed configuration switch than the other layers?

• distribution
• transport
• internet
• access
• core

A network engineer is interested in obtaining specific information relevant to the operation of both distribution and access layer Cisco devices. Which command provides common information relevant to both types of devices?

• show ip protocols
• show ip interface
• show cdp neighbors
• show port-security
• show mac-address-table

A switched network has converged completely. All switches currently have a VTP revision number of 5. A new switch that has been configured as a VTP server is added to the network. The new switch has a VTP revision number of 4. What will occur within the network?

• The network will no longer share VLAN database updates.
• The newly added switch will automatically switch to VTP client mode.
• The VTP databases will remain unchanged in all switches with the exception of the newly added switch.
• All switches in the network will update their VTP database to reflect the VTP database of the new switch.

A network administrator is adding a new VLAN for testing. The company uses VTP and the VLAN is not directly attached to either of the switches configured as VTP servers. What is the best method to add this VLAN to the network?

• Change the switch that has connected hosts in the new VLAN to be in VTP server mode.
• Configure a port on the VTP servers for the same VLAN as the new VLAN.
• Manually add the VLAN to the VLAN database of the VTP servers.
• Configure interfaces on the switch that has connected hosts in the new VLAN and reboot the switch.

Refer to the exhibit. The configuration shows the commands entered by a network administrator for inter-VLAN routing. However, host PCA cannot communicate with PCB. Which part of the inter-VLAN configuration causes the problem?

• trunking

• port mode on the two switch

• FastEthernet ports

• VLAN configuration

• router port configuration

Refer to the exhibit. What is the role of the SW3 switch?

• designated switch

• edge switch

• root bridge

• enabled bridge

• local bridge

Which spanning tree standard was developed by Cisco to provide separate instances of 802.1w per VLAN?

• RSTP
• 802.1D
• MSTP
• Rapid PVST+

Which industry-wide specification was developed to decrease the time that is needed to move to the forwarding state by switch ports that are operating in a redundantly switched topology?

• VLSM
• PVST
• 802.1Q
• RSTP
• VTP

Refer to the exhibit. A network administrator is verifying the bridge ID and the status of this switch in the STP election. Which statement is correct based on the command output?

• The bridge priority of Switch_2 has been lowered to a predefined value to become the root bridge.

• The bridge priority of Switch_2 has been lowered to a predefined value to become the backup root bridge.

• The STP instance on Switch_2 is failing due to no ports being blocked and all switches believing they are the root.

• The STP instance on Switch_2 is using the default STP priority and the election is based on Switch_2 MAC address.
