Europe. You work at the New York Office. Recently a new switch block with multiple VLANs configured were added to the Barcelona LAN.
Your boss at， Miss， tells you that the personal at the Barcelona office failed to document the spanning tree topology during installation. She gives you a plane ticket to Barcelona and orders to provide a baseline of configuration information in regard to the switch block spanning tree topology. Two days later you arrive at the Barcelona office. You study the network topology carefully， see exhibit. Then you connect to the 3 switch； issue the show spanning tree command. Please refer to the exhibit for the output. You are then required to answer the scenario questions using the information that is available.

2.判斷題 The network is displayed in the diagram below：

You have just been hired by to help their main office expand. The main offices have enhanced their wiring closets with some Layer 3 switches. The new distribution layer switch has been installed and a new access layer switch cabled next to it. Your task is to configure the distribution layer and access layer
switch with VTP to share VLAN information， then to configure inter-VLAN routing on the distribution layer switch to route traffic between the different VLANs that are configured on the access layer switches.
VTP Domain Distribution
VLAN Ids 20 31
IP Addresses 172.16.71.1/24 172.16.132.1/24
These are your specific tasks：
1. Configure the VTP information with the distribution layer switch as the VTP server
2. Configure the VTP information with the access layer switch as a VTP client
3. Configure VLANs on the distribution layer switch
4. Configure inter-VLAN routing on the distribution layer switch
5. Specific VLAN port assignments will be made as users are added to the access layer switches in the future.
6. All VLANs and VTP configurations are to completed in the global configuration
To configure the switch click on the host icon that is connected to the switch be way of a serial console cable.

4.判斷題
Each of these vlans has one host each on its port SVI on vlan 1 - ip 192.168.1.11 with snm Switch B -
Ports 3， 4 connected to ports 3 and 4 on Switch A
Port 15 connected to Port on Router.
Tasks to do
1. Use non proprietary mode of aggregation with Switch B being the initiator -- Assumed use LACP with B being in Active mode
2. Use non proprietary trunking and no negotiation -- Assumed use switchport mode trunk and switchport trunk encapsulation dot1q
3. Restrict only to vlans needed
-- Assumed either vtp pruning or allowed vlan list. vtp pruning command did not seem to work on the simulator so landed using allowed vlan list
4. SVI on vlan 1 with some ip and subnet given
5. Configure switch A so that nodes other side of Router C are accessible -- Assumed this to mean that on switch A default gatway has to be configured.
6. Make switch B the root
-- Could not get this to work. Exam hung when I tried the command spanning-tree vlan 1，21-23 priority 4096
