Questions & Answers

Q: What are the key elements discussed in campus network design considerations?

The key elements include convergence times, multi-layer switching, quality of service considerations, load sharing in layer 2 and layer 3 switches, and infrastructure device characteristics.

Q: How do data link layer and multi-layer switching differ in enterprise networks?

Data link layer switching operates at the MAC address level, while multi-layer switching can perform packet switching at higher OSI layers and can replace routers in LAN environments.

Q: What is the significance of quality of service considerations in LAN switches?

Quality of service mechanisms are crucial for managing network resources, ensuring predictable and guaranteed service levels, and handling delay, jitter, bandwidth, and packet loss in LAN switches.

Q: How does load sharing work in layer 2 and layer 3 switches?

Layer 2 load sharing is based on MAC addresses, while layer 3 load sharing is IP-based, allowing for more proportional use of links and better adaptability to dynamic application needs.
