Implementing Cisco IP Switched Networks (SWITCH v2-0) (#443)

Refer to the exhibit.

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?

Delete vlan.dat and ensure that the switch with lowest MAC address is the VTP server.
Disable DTP and document the VTP domain mismatch.
Manually force trunking with switchport mode trunk on both switches.
Enable the company B switch with the vtp mode server command.
