Network Configuration Essentials: VLANs, STP, and VTP

1. Analyzing Exhibit Information for Network Conclusions

Refer to the exhibit. Which two statements can be concluded from the information shown in the exhibit? (Choose two.)

• All ports listed in the exhibit are access ports.
• A router connected to the switch is required to forward traffic between hosts.

2. Router Packet Forwarding on Uplink Trunk

A router is configured to connect to an uplink trunk, as shown in the exhibit. A packet is received on the FastEthernet 0/1 physical interface from VLAN 10. The packet's destination address is 192.168.1.120. What will the router do with this packet?

• The router will forward the packet to the FastEthernet 0/1.2 interface with VLAN tagging for 60.

3. BPDU Information Usage in Spanning Tree Protocol

For which two purposes is the information contained in a BPDU used? (Choose two.)

• To determine the shortest path to the root bridge.
• To determine which ports will forward frames as part of the Spanning Tree.

4. Efficient VLAN Routing with Router Subinterfaces

A router has two serial interfaces and two Fast Ethernet interfaces. This router must be connected to a WAN link and a switch that supports four VLANs. How can the most efficient and cost-effective VLAN routing between the four VLANs be achieved?

• Connect an uplink from the trunk switch to a Fast Ethernet interface on the router and create logical subinterfaces for each VLAN.

5. MAC Address Removal from CAM Table

When are MAC addresses removed from the CAM table?

• After having been idle for a certain period of time.

6. Reasons for VTP Management Process Discrepancy

Refer to the exhibit. Switch1 is not participating in the VTP management process with the other switches. What are two possible reasons for this? (Choose two.)

• Switch1 is using VTP version 1 and Switch2 is using VTP version 2.
• Switch1 is in a different management domain.

7. Router Interface Configuration for VLAN Trunking

Which three elements must be used when a router interface is configured for VLAN trunking? (Choose three.)

• One subinterface per VLAN.
• An IP network or subnetwork for each subinterface.
• A compatible trunking protocol encapsulation for each subinterface.

8. VLAN Propagation Issue in VTP Domain

Refer to the exhibit. The switches are connected to the same VTP domain. Each switch is marked with its VTP mode. A new VLAN is added to Switch3. This VLAN does not appear on the other switches. What is the reason for this?

• VLANs configured on switches in transparent mode are not included in VTP advertisements.

9. STP Root Bridge Selection Criteria

Which two criteria are used by STP to select a root bridge? (Choose two.)

• Bridge priority.
• Base MAC address.

10. Preparing a Catalyst Switch for a New VTP Domain

What three steps should be taken before moving a Catalyst switch to a new VTP management domain? (Choose three.)

• Restart the switch and zero VTP counters to allow it to synchronize with other switches in the domain.
• Select the correct VTP mode and version.
• Configure the switch with the new VTP domain name.
