Exam A
QUESTION 1
Acme is a small export company that has an existing enterprise network comprised of 5 switches;
CORE,DSW1,DSW2,ASW1 and ASW2. The topology diagram indicates their desired pre-VLAN spanning
tree mapping.
Previous configuration attempts have resulted in the following issues:
每
CORE should be the root bridge for VLAN 20; however, DSW1 is currently the root bridge for VLAN 20.
每
Traffic for VLAN 30 should be forwarding over the gig 1/0/6 trunk port between DSW1 and DSW2. However VLAN 30 is currently using gig 1/0/5.
每
Traffic for VLAN 40 should be forwarding over the gig 1/0/5 trunk port between DSW1 and DSW2. However VLAN 40 is currently using gig 1/0/6.
You have been tasked with isolating the cause of these issuer and implementing the appropriate solutions. You task is complicated by the fact that you only have full access to DSW1, with isolating the cause of these issues and implementing the appropriate solutions. Your task is complicated by the fact that you only have full access to DSW1, with the enable secret password cisco. Only limited show command access is provided on CORE, and DSW2 using the enable 2 level with a password of acme. No configuration

Correct Answer: configure terminal spanning-tree vlan 20 priority 61440 interface g1/0/6 spanning-tree vlan 30 port-priority 64 exit interface g1/0/5 spanning-tree vlan 40 cost 1 show spanning-tree copy run start
Section: (none) Explanation
Explanation/Reference:
By using the ※show spanning-tree§ command as shown above, we learned that DSW1 is the root bridge for VLAN 20 (notice the line ※This bridge is the root§
To determine the root bridge, switches send and compare their priorities and MAC addresses with each other. The switch with the lowest priority value will have highest priority and become the root bridge. Therefore, we can deduce that the priority of DSW1 switch is lower than the priority of the CORE switch so it becomes the root bridge. To make the CORE the root bridge we need to increase the DSW1∩s priority value, the best value should be 61440 because it is the biggest value allowed to assign and it will surely greater than of CORE switch. (You can use another value but make sure it is greater than the CORE priority value by checking if the CORE becomes the root bridge or not; and that value must be in incrementsof 4096).

Exam A
QUESTION 1
VTP devices in a network track the VTP revision number. What is a VTP configuration revision number?
A. A number for identifyiing changes to the network switch
B. A number for identifying changes in the network router
C. A number for identifying changes to the network topology
D. none of the other alternatives apply
Correct Answer: C Section: (none) Explanation
Explanation/Reference:
The configuration revision number is a 32 bit number that indicates the level of revision for a VTP packet.
Each VTP device tracks the VTP configurationa revision number assigned to it, and most of the VTP
packets contain the VTP configuration revision number of the sender.
This information is used to determine whether the received information is more recent that the current
revision of a switch, change the VTP domain name and then change it back to the original name.
