How does BGP's route aggregation feature benefit network performance and scalability?
- Reducing the number of routing entries
- Increasing the BGP peer connections
- Utilizing MPLS technology
- Implementing OSPF as the IGP
BGP's route aggregation feature benefits network performance and scalability by reducing the number of routing entries in the routing table.
How does SDN address the issue of scalability in large network infrastructures?
- By decoupling the control plane from the data plane, SDN allows centralized control, making it easier to scale and manage large networks.
- By using traditional routing protocols that automatically scale to accommodate network growth.
- By relying on complex distributed algorithms that dynamically adjust network resources.
- By limiting the size of the network to maintain manageable scalability.
SDN addresses scalability by decoupling the control and data planes, enabling centralized control for easier scaling in large networks.

In troubleshooting a network that frequently loses connection, what systematic approach should be used to pinpoint the exact cause?
- Check for interference in wireless networks
- Implement QoS for better connectivity
- Conduct a packet capture analysis
- Update network device firmware
To pinpoint the exact cause of frequent connection losses, a systematic approach involves conducting a packet capture analysis to examine network traffic and identify potential issues.
