Really? I thought 1 Gbps would always be better than 100 Mbps.

Using G.711 over G.729 can impact bandwidth, but not always the main issue.

I'm a bit confused by this question. The breakeven chart shows the relationship between costs, revenue, and volume, but I'm not sure how to directly translate that to the forecast profit. I'll need to review my notes on interpreting these types of charts.

This seems straightforward. The `pushState()` method updates the browser's history without triggering a full page reload, so I'd expect a `popstate` event to fire when the back button is clicked.
