Hi @Yu Kang ,
Microsoft Certification / Exams is currently not supported in the Q&A forums.
Maybe one of the links is helpful:
Microsoft Training & Certification is supported on their own forums:
Microsoft Certification - Profile/MCID Assistance: https://trainingsupport.microsoft.com/en-us/mcp/forum/mcp_prof-mcp_mcid
Microsoft Certification - Profile/Account Linking: https://trainingsupport.microsoft.com/en-us/mcp/forum/mcp_prof-mcp_link
