The network switches for two companies have been connected and manually configured for the required VLANs, but users in company A are not able to access network resources in company B when DTP is enabled. Which action resolves this problem?
| A. |
Delete vlan.dat and ensure that the switch with lowest MAC address is the VTP server. | |
| B. |
Disable DTP and document the VTP domain mismatch. | |
| C. |
Manually force trunking with switchport mode trunk on both switches. | |
| D. |
Enable the company B switch with the vtp mode server command. |
Since the number of existing VLANs differ on the switches (9 on A and 42 on B) we know that there is a problem with VTP or the trunking interfaces. The VTP domain names do match and they are both VTP servers so there are no issues there. The only viable solution is that there is a DTP issues and so you must instead manually configure the trunk ports between these two switches so that the VLAN information can be sent to each switch.
