Which of the following is NOT a default setting for a Cisco Catalyst Switch?

The correct response highlights that all interfaces on a Cisco Catalyst Switch are not assigned to VLAN 2 by default. In fact, when you initialize a Cisco Catalyst Switch, all interfaces are assigned to the default VLAN, which is VLAN 1. This means that by default, all ports are in VLAN 1 and can communicate with each other unless specifically configured to belong to a different VLAN.

The other options reflect typical default behaviors of Cisco Catalyst switches. For instance, switches typically have all interfaces enabled so that they can pass traffic immediately, Spanning Tree Protocol (STP) is enabled by default to prevent loops in the network, and interfaces generally use autonegotiation to configure their speed and duplex settings dynamically. Understanding these defaults is crucial for network administrators configuring switches, as they can have significant implications for network performance and reliability.
