Multiple Choice

By default, the switch ports belong to which VLAN?

Explanation:
When a switch starts up, all unconfigured access ports are placed into the default VLAN, which is VLAN 1. This means untagged frames on those ports are considered part of VLAN 1, and management traffic on the switch is typically associated with that same VLAN unless you change it. On trunk links, frames for multiple VLANs travel with tags, but the native (untagged) VLAN on the trunk is also VLAN 1 by default, so untagged traffic on that link belongs to VLAN 1 as well. You would specify a different VLAN for a port only if you configure it as an access port to a specific VLAN or set a different native VLAN on a trunk. So, by default, switch ports belong to VLAN 1.
