I built a network in the lab with multiple PCs and switches and everything pings fine without VLANs. So why bother? What real problem do VLANs solve? My instructor says they're essential but I don't see why when the flat network already works.
I can configure both static routes and default routes on a router. But when should I use a specific static route pointing to a network vs just a default route that catches everything? Is there a best practice for small networks vs large ones?
I keep seeing both mentioned in my studies and they both do routing. When would you use a router vs a Layer 3 switch? Is one faster? Are there features only a router can do? Would love a clear explanation of when to pick each one in a real network design.
