Hi there
It was most likely a NetAcad CCNA certification.
NetAcad would mean you studied the material in school and did the exams in school.
IN which case you would need to contact your teacher who could look up your details.
If it was A Cisco certification you would have had to register with Pearson Vue to do an external exam.
