• SwitchB VTP mode needs to be the same as Switch

CORRECT TEXT
Scenario:
You work for SWITCH.com. They have just added a new switch (SwitchB) to the existing network
as shown in the topology diagram.
RouterA is currently configured correctly and is providing the routing function for devices on
SwitchA and SwitchB. SwitchA is currently configured correctly, but will need to be modified to
support the addition of SwitchB. SwitchB has a minimal configuration. You have been tasked with
competing the needed configuring of SwitchA and SwitchB. SwitchA and SwitchB use Cisco as the
enable password.
Configuration Requirements for SwitchA
The VTP and STP configuration modes on SwitchA should not be modified.
• SwitchA needs to be the root switch for vlans 11, 12, 13, 21, 22 and 23. All other vlans should
be left are their default values.
Configuration Requirements for SwitchB
• Vlan 21
Name: Marketing
will support two servers attached to fa0/9 and fa0/10
• Vlan 22
Name: Sales

– will support two servers attached to fa0/13 and fa0/14
• Vlan 23
o Name: Engineering
o will support two servers attached to fa0/15 and fa0/16
• Access ports that connect to server should transition immediately to forwarding state upon
detecting the connection of a device.
• SwitchB VTP mode needs to be the same as SwitchA.
• SwitchB must operate in the same spanning tree mode as SwitchA
• No routing is to be configured on SwitchB
• Only the SVI vlan 1 is to be configured and it is to use address 192.168.1.11/24
Inter-switch Connectivity Configuration Requirements
• For operational and security reasons trunking should be unconditional and Vlans 1, 21, 22 and
23 should tagged when traversing the trunk link.
• The two trunks between SwitchA and SwitchB need to be configured in a mode that allows for
the maximum use of their bandwidth for all vlans. This mode should be done with a nonproprietary protocol, with SwitchA controlling activation.
• Propagation of unnecessary broadcasts should be limited using manual pruning on this trunk
link.
