Most of us probably don’t sit around meticulously reading the exam topics of vendor certification exams. But if you did, you might have noticed the announcement of a few new career certifications from Cisco this week. And if you look closely at one of the exam blueprints, for the first of two exams related to the CCNA Cloud certification, you’d see a bit of a milestone:
