  5. Layer 2 networks were originally built to handle the performance requirements of LAN interconnectivity, whereas Layer 3 routers could not accommodate multiple interfaces running at near wire-rate speed. Today, Layer 3 campus LAN networks can achieve the same performance of Layer 2 campus LAN networks due to the following technology change:

    1. Layer 3 switches are now built using specialized components that enable similar performance for both Layer 2 and Layer 3 switching.
    2. Layer 3 switches can generally switch packets faster than Layer 2 switches.
    3. Layer 3 switches are now built using multiple virtual routers enabling higher speed interfaces.
  6. Why are Layer 2 domains popular in data center designs?

    1. Data centers do not require the same scalability as the campus network.
    2. Data centers do not require fast convergence.
    3. Data centers place heavier emphasis on low-latency, whereas some applications operate at Layer 2 in an effort to reduce Layer 3 protocol overhead.

    2. Up to 200 users
    3. Up to 2000 users
    4. Between 500 to 2500 users
    5. Between 1000 to 10,000 users

    1. Simplification of large-scale designs.
    2. Reduce complexity of troubleshooting analysis.
    3. Reduce costs by 50 percent compared to flat network designs.
