Refer to the exhibit. The network administrator has just added VLAN 50 to Switch1 and Switch2 and assigned hosts on the IP addresses of the VLAN in the 10.1.50.0/24 subnet range. Computer A can communicate with computer B, but not with computer C or computer D. What is the most likely cause of this problem?

There is a native VLAN mismatch.

The link between Switch1 and Switch2 is up but not trunked.

The router is not properly configured for inter-VLAN routing.

VLAN 50 is not allowed to entering the trunk between Switch1 and Switch2.

Refer to the exhibit. The exhibited configurations do not allow the switches to form a trunk. What is the most likely cause of this problem?

Cisco switches only support the ISL trunking protocol.

The trunk cannot be negotiated with both ends set to auto.

By default, Switch1 will only allow VLAN 5 across the link.

A common native VLAN should have been configured on the switches.
