NEW QUESTION 27

You have been asked to install and configure a new switch in a customer network. Use the console access to the existing and new switches to configure and verify correct device configuration.



You are connecting the New_Switch to the LAN topology; the switch has been partially configured and you need to complete the rest of configuration to enable PC1 communication with PC2. Which of the configuration is correct?

• A. Option A
• B. Option B
• C. Option C
• D. Option D
• E. Option E

Answer: D

Explanation:
Within any VTP, the VTP domain name must match. So, step one is to find the correct VTP name on the other
switches. Logging in to SW1 and using the “show vtp status” command we see this:

So we know that the VTP domain must be CCNP. This leaves only choice D and E. We also see from the topology diagram that eth 0/0 of the new switch connects to a PC in VLNA 100, so we know that this port must be an access port in VLAN 100, leaving only choice D as correct. Note that the VTP versions supported in this network are 1, 2, 3 so either VTP version 2 or 3 can be configured on the new switch.
