One of the C100Dev exam question need to be fixed

Hi, I recently took the C100Dev exam. One of the question(either in CRUD or Aggregation Framework section) related to the update operations, its Object id field in the question are different from and 4 option choices that test taker can choose. Eg. in the question the ObjectId is like “00000011”, but in the all four choices it shows as “000000ff”, although it doesn’t affect test taker to choose the correct one from question design point of view, but it just doesn’t feel right.

Hi @Junlei_Li,

Thank you for sharing your feedback!!

I have reported this to our Certification team and we will debug and fix the question as soon as possible.

I would also like to congratulate you on passing the C100DEV MongoDB Certified Developer Associate Exam :clap:

Kind Regards,
