Switched Networks Quiz

What are the elements of a converged network?

• Hardware, software, and firmware

• Data, voice, and video

• Input, output, and processing

• LAN, WAN, and MAN

What are the principles of the hierarchical borderless switched network design?

• Wired, wireless, and policy

• Security, reliability, and availability

• Modularity, resiliency, and flexibility

• Flexibility, scalability, and reliability

What is the role of a hierarchical switched LAN?

• To support legacy devices

• To support only wireless networking

• To provide additional security

• To provide flexibility and traffic management

What are the considerations when selecting switches?

• Cost, power, and frame buffers

• Port speed, reliability, and scalability

• Port density, frame buffers, and scalability

• Cost, power, and reliability

How does a LAN switch make forwarding decisions?

• Based on ingress port and source address

• Based on destination address and port speed

• Based on cost and reliability

• Based on frame size and buffer capacity

What is the primary method of LAN switching used by Cisco?

• Rapid Frame Forwarding

What do Ethernet switch ports operating in full duplex eliminate?

• Network congestion

• Port speed limitations

• Collisions

• Broadcast domains

What happens when two or more switches are connected together in terms of broadcast domains?

• The broadcast domain is isolated

• The broadcast domain is decreased

• The broadcast domain is eliminated

• The broadcast domain is increased

Which characteristics of switches help alleviate network congestion?

• Half-duplex links and low port speed

• Small frame buffers and low per-port cost

• Low port density and slow internal switching

• High port density and large frame buffers

What is the primary benefit of a converged network?
