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.
