Reimagining the Azure Solutions Architect Expert certification

hykok, our exam numbers don't reflect the level of expertise you require to earn a certification. All our fundamentals certification exams are XX-900 .

What indicates the level of expertise is the "Fundamentals", "Associate", "Expert", or "Specialty" word that qualify each one of the certifications:

Azure Fundamentals

Azure Administrator Associate

Azure Solutions Architect Expert

Since you already have passed Exam AZ-303, you have choices, depending on how far are you on your preparation for Exam AZ-304, or when you want to earn your Azure Solutions Architect Expert certification:

• If you are ready to take Exam AZ-304, I'd go for it.
• If you need/want to earn your Azure Solutions Architect Expert certification before November 16, 2021, you should take and pass Exam AZ-304 now.
• If you can/want wait until November, I'd take the Exam AZ-305. As I mention in another answer, you can start preparing for Exam AZ-304, adding the Cloud Adoption Framework for Azure and the Azure Well-Architected Framework, and take Exam AZ-305 once it is available.

When we release Exam AZ-305 on November 16, 2021, we will have the usual beta discount (for a limited number of people, a limited time period, and available in certain countries).
