I worked for an ISP for some years. Leased lines usually don't use HDLC/PPP anymore, as the technology is way too slow for most companies needs. They use QinQ (double dot1q tagging) to tag all your traffic with an extra vlan tag (called the service vlan). This allows lots of fast leased line connection (10g+) over the same infrastructure, and the ISP doesn't have to worry about vlan leaking or mismatches. This also solves problems with several companies needing p2p trunk link transits over same infrastructure/datacentres, as all your traffic, untagged or tagged, will just be tagged with an extra vlan id over the ISPs infrastructure. The extra vlan tag will then be removed as the traffic reaches the other end of the leased line. This basically solves the same problem in leased lines, as MPLS solves in internet connections: being able to use the same infrastructure without mixing customer traffic. The ISP i worked in was quite small, and they had used this for over 10 years when i started. This is in Norway btw, I'm not sure what standards are in other countries.

I guess you're referring to Ethernet connections (like Metro Ethernet), since you mentioned QinQ. I was referring to serial leased lines in this video, hence HDLC/PPP.

My three week points on the exam were within Security (67%), Network Access (70%), and Automation and Programmability (80%). These are the newest additions, and wireless falls within each one. I would really like to see you do at least a two day course on Wireless because it cover so much ground. I'm looking forward to it, even though I've already passed the exam!
