Which protocol is commonly used to negotiate EtherChannel links between Cisco switches?

  • CDP (Cisco Discovery Protocol)
  • OSPF (Open Shortest Path First)
  • PAgP (Port Aggregation Protocol)
  • STP (Spanning Tree Protocol)
PAgP (Port Aggregation Protocol) is commonly used to negotiate EtherChannel links between Cisco switches.

How does chassis aggregation differ from traditional switch stacking?

  • Both physical and logical connections
  • Logical connection
  • No connection
  • Physical connection
Chassis aggregation involves both physical and logical connections between switches, whereas traditional switch stacking primarily uses a physical connection.

For high-speed data transmission over long distances, which type of cable is most appropriate?

  • Coaxial
  • Ethernet
  • Fiber Optic
  • Twisted Pair
Fiber optic cables are most appropriate for high-speed data transmission over long distances due to their high bandwidth and immunity to electromagnetic interference.

What is the primary purpose of NAT (Network Address Translation) in a home or small office network?

  • Conserving public IP addresses
  • Enhancing network security
  • Improving wireless connectivity
  • Increasing network speed
The primary purpose of NAT is to conserve public IP addresses by allowing multiple devices in a private network to share a single public IP address.

SDN helps in separating which two key functions of traditional networking for more efficient network management?

  • Data and control planes
  • Physical and logical planes
  • Switching and routing
  • LAN and WAN
SDN separates the data and control planes, allowing centralized control for more efficient network management.
