Answer 1

They are probably talking about MPLS type networks where companies rent access to fibre cabling to run private networks between their offices/data centers

It’s sometimes private cables, sometimes guaranteed segmented bandwidth on shared cables

By design it’s not accessible from the internet and is designed for reliable and relatively secure networking between sites
