To all my mates who are looking forward to appearing in the 1Z0-160 exam and seeking advice from me on the same, I would just like to say that focus on the course material provided by K21academy, listen to the videos carefully multiple times, practice the deployments n all services multiple times, remember few commands i.e. backup, recovery, ords, and most importantly practice, and once you are confident, the DBCS certification is yours.
Thanks and Best wishes.
