What are three characteristics of a Switch Virtual Interface (SVI)?

A Switch Virtual Interface (SVI) is a virtual interface that exists within a VLAN, and it is commonly used for Layer 3 routing on switches. One of the key characteristics of an SVI is that it is, by default, associated with VLAN1. This means that when you set up a switch, the SVI for VLAN1 is automatically created, allowing the switch to process IP traffic on that VLAN without the need for a physical interface.

In addition to its default association, an SVI provides Layer 3 routing capabilities for that VLAN and serves as the default gateway for devices on that VLAN. This allows devices to communicate with each other and with devices on other VLANs if routing is enabled. However, an SVI's functionality extends beyond just VLAN1, as it can be configured for any VLAN on the switch.

The option indicating that an SVI is only associated with physical interfaces is incorrect because an SVI is a virtual interface. It doesn't require a physical interface to operate; rather, it is logically tied to a VLAN instead of a direct physical connection. Similarly, the statement that an SVI is not associated with any physical interface misses the point that while an SVI is indeed a virtual interface, it represents a logical connectivity
