You’re totally right Jurkinss. I already found the same.
I also checked that there are different answers as correct for the same question 🙂
On exame “Timed Mode Set 2 – Google Certified Associate Cloud Engineer” the answer defined as correct is the one related to Cloud Storage (not correct in my opinion).
However, on the exame “Review Mode Set 2 – Google Certified Associate Cloud Engineer” the answer defined as the correct one is related to Source Repositories 🙂
