Hi there!
Unfortunately, we do not have a certification called HCIA R&S FastTrack. Sometimes though, the training is delivered within 5 days (using only the second book of the standard 2 books).
Some trainees have basic knowledge in terms of network technologies and only 1 exam for standard training and streamlined training (the exam contains 60 questions to be completed within 90 minutes).
Thanks and I hope that answers your question.
