13. B, C. Interface Gig1/0/33 is not listed as a member of VLAN 10, so it could be configured for a different VLAN. The interface could also be configured as a trunk carrying one or more VLANs. In that case, it would not be listed as a member of VLAN 10 only.
14. C. Because the interfaces begin with their default configurations, each one uses native VLAN 1. Even though the interfaces are not configured with a consistent list of allowed VLANs, that will not prevent the trunk link from being negotiated. The real reason the trunk is not working is that both switches are configured with dynamic auto mode, causing neither switch to actively negotiate a trunk. Instead, each switch is waiting for the other one to ask for a trunk link.

9. C. Because of the variety of user host platforms, port-based authentication (802.1X) cannot be used. The problem also states that the goal is to restrict access to physical switch ports, so AAA is of no benefit. Port security can do the job by restricting access according to the end users’ MAC addresses.
