Benefits & Tips

  • 합격하면 다음 시험 50% 할인 바우처가 생깁니다. AWS Certification 계정의 "Benefits"에서 확인하고 재인증·다른 자격증 응시에 쓸 수 있어요(만료일이 있으니 그 전에 사용).
  • 인증은 3년간 유효하며 만료 전 재인증이 필요합니다. 재인증 때도 이 50% 바우처를 쓸 수 있어요.
  • 무료 재응시는 없습니다(매 응시 전액 결제). 첫 시도에 붙는 게 가장 저렴하니, 모의고사로 합격선을 넘긴 뒤 응시하세요.
  • 합격하면 Credly 디지털 배지가 발급돼 링크드인·이메일 서명에 붙일 수 있습니다.
