Which characteristics apply to multilayer switching? (Choose three.)

  • Uses CPU-based packet forwarding
  • Performs collision detection
  • Provides isolation of the collision domain
  • Provides Network-layer and Transport-layer access controls
  • Determines the forwarding path based on the Network layer address
Explanation:

Multilayer switching characteristics include determining the forwarding path based on the Network layer address (Layer 3), providing isolation of the collision domain (Layer 2); and providing Network-layer and Transport-layer access controls (Layers 3 and 4).

Multilayer switching combines the functionalities of Layer 2 switching and Layer 3 switching. Layer 3 switching is routing performed by hardware, specifically by utilizing application-specific integrated circuits (ASICs). The Layer 3 switch can perform all of the basic operations of traditional routers, including the following:

  • Path selection based on the packet’s Layer 3 protocol information
  • Layer 3 packet validation
  • Flow accounting (Layers 3 and 4)
  • Layer 3-based access controls and security

In contrast to Layer 2 switches, which provide the benefits of bridging, Layer 3 switches offer another high-performance packet switching solution.

CPU- based packet forwarding and collision detection are not unique characteristics of multilayer switching. CPU-based packet forwarding is not a concept used by routers or switches. Collision detection is a characteristic of Ethernet, which is not unique to multilayer switching.
