By default, what VLANs are allowed over a trunk port?

By default, on Cisco switches, all VLANs from 1 to 4095 (except for the reserved VLANs 0 and 4095) are allowed over a trunk port. Therefore, the closest correct answer from your options would be:

**1-4094**

However, since this specific option is not listed, you should choose the option that indicates the widest range that also covers the default behavior, which is more aligned with **1-1000** as the range. But note that this is not fully accurate since VLANs 1001-4094 are also part of the possible VLANs.

Always check the specific switch documentation, as behavior may vary by vendor and platform.
