What are three characteristics of an svi? (choose three.)
it is required to allow connectivity by any device at any location. it is designed as a security protocol to protect switch ports. it provides a means to remotely manage a switch. it is not associated with any physical interface on a switch. it is associated with vlan1 by default. it is a special interface that allows connectivity by different types of media.
The Correct Answer and Explanation is:
The correct characteristics of an SVI (Switched Virtual Interface) are:
- It provides a means to remotely manage a switch.
- It is not associated with any physical interface on a switch.
- It is associated with VLAN 1 by default.
Explanation:
An SVI (Switched Virtual Interface) is a virtual interface in a network switch that provides Layer 3 functionality. It allows for communication between devices on different VLANs and facilitates management of the switch.
- It provides a means to remotely manage a switch:
An SVI serves as a virtual interface that allows remote management of a switch via IP-based protocols like Telnet or SSH. Typically, the switch has a management IP address configured on the SVI, enabling administrators to access the switch over the network for configuration and troubleshooting purposes. - It is not associated with any physical interface on a switch:
Unlike physical interfaces such as Ethernet ports, an SVI does not correspond to a physical port. It is a logical, software-defined interface within the switch that allows the switch to function at Layer 3 (network layer). This is crucial because, while switches primarily operate at Layer 2 (data link layer) for MAC address-based forwarding, SVIs allow the switch to perform routing and provide IP connectivity. - It is associated with VLAN 1 by default:
By default, VLAN 1 is assigned as the management VLAN on most switches. The SVI for VLAN 1 is created automatically and provides the default IP address for remote management. This means that the switch will use the IP address of the SVI in VLAN 1 for remote management unless another VLAN is specifically configured to handle this task.
Incorrect Options:
- Required to allow connectivity by any device at any location: This is not accurate. SVIs enable communication within a VLAN or between different VLANs, but they don’t guarantee connectivity by any device at any location without proper routing and network configurations.
- Designed as a security protocol to protect switch ports: SVIs are not designed as security protocols but are virtual interfaces for routing and management. Security features may exist within VLAN configurations, but an SVI itself does not act as a security protocol.
- Special interface that allows connectivity by different types of media: SVIs do not directly handle multiple types of media. They provide Layer 3 routing functionality between VLANs, which may involve different physical media but are not directly tied to handling different media types.
