FAQs About Enterprise Networking
Q: How often should network equipment be refreshed? A: 5-7 years for switches/routers, 3-4 years for wireless APs. Budget 15-20% of initial cost annually for refresh.
Q: What’s the difference between managed and unmanaged switches? A: Managed switches offer VLANs, QoS, SNMP monitoring, security features. Unmanaged are plug-and-play but lack visibility/control. Always use managed switches in enterprise environments.
Q: How much bandwidth do we need per employee? A: 50-100 Mbps per user for typical office work. 100-200 Mbps for video-heavy roles. Multiply by concurrent users and add 30% overhead.
Q: Can SD-WAN replace MPLS completely? A: Yes, but hybrid approach is common: keep MPLS for critical traffic, use SD-WAN with broadband/4G for general traffic. Reduces costs while maintaining quality.
Q: How do we secure IoT devices on the network? A: Network segmentation is key. Create separate VLAN for IoT, implement MAC address filtering, and use next-gen firewall to restrict IoT-to- corporate communication.
