Which VLAN is typically used as the default on many switches and is often the first configured VLAN?

Explanation:
VLAN 1 is the default on many switches, and it’s typically the first one you encounter when configuring a device. This VLAN is treated as the native or management VLAN in default switch configurations, meaning untagged traffic on access ports usually falls into this VLAN and the switch’s management interface (the IP used to manage the device) is often assigned here. Because of this built‑in default, VLAN 1 is the most common starting point for initial setups. Other numbers aren’t the standard default. VLAN 0 isn’t a real, assignable VLAN in most setups (it’s used in protocol contexts to mean “no VLAN” in some situations), and numbers like 100 or 999 are simply user-defined or reserved in some environments. So VLAN 1 fits as the typical default and first configured VLAN.
