Exam details of AZ-303 and AZ-304

In order to achieve an Azure Solutions Architect Certification, one must qualify for both AZ-303 and AZ-304 certification exams. AZ-303 focuses on the practical aspect, while the AZ-304 is more about Designing part. The domains that will be covered in the exams are:


The certification’s infrastructure emphasizes Azure assets like virtual machines, networks, applications, and Azure Resource Manager (ARM) layouts. The practitioner must be proficient in configuring and deploying assets and formats, where the designer should decide how the assets will be arranged and select the compute technology and any potential automation opportunities. Both the practitioner and the architect will likewise have information regarding the application services, web applications, logic applications and functions, and container-based applications like Azure Kubernetes Service.


Domains like logging, metrics, reporting, and alerts are incorporated by Monitoring. The practitioner must demonstrate their direct monitoring insight, like performance capacity, service health, and spend, just as configuring logging and alerts. The person in charge of designing will find out the explanations for cost minimization, monitoring tools, and strategies similar to event routing and escalation. The configuration would likewise incorporate the dynamic for what measurements would be significantly dependent on the business needs.


Management deals in different territories that incorporate business continuity, identity, security, and relocation from other infrastructures, namely on-premises datacenters. In order to have an identity and increased security, the designer must direct blueprinting single-sign-on and validation with hybrid and multi-factor options, authorization like role-based admittance control and tasks, administration strategies using Azure Policy and Azure Blueprint, and finally, security solutions like Azure Key Vault. The practitioner will know about sending these intricate arrangements in another or existing Azure environment. Business coherence is tied in with keeping the lights on, no matter what. This includes backup and disaster recovery, load balancing, replication, or other applications and data conveyance across all significant business locales. Relocation is another vital piece to the executives. The implementer is ready to move the remaining tasks at hand utilizing Azure Migrate. The architect is prepared to survey and interpret on-premises servers, data, and applications, then coming up with an arrangement for moving every tremendous burden to the cloud.

The differences between the AZ-303 and AZ-304

Comparing AZ-303 and AZ-304 is like comparing Implementation and Design. AZ-304 entirely focuses on designing any application, and AZ-303 focuses on executing the design framed by the AZ-304 certified executives.

  • The designer (AZ-304) will be concentrating on gathering business requirements after taking real-world examples into consideration, constraints, and business objectives, and choosing solution implementations on the basis of the requests of an organization.
  • The implementer (AZ-303) accepts those solutions and ensures that they are appropriately developed, implemented, or migrated.


Many candidates prefer taking the AZ-303 exam prior to the AZ-304. One of the important reasons is that once you’ve proven that you are aware of the Azure services’ ins and outs in the AZ-303, the AZ-304 exam helps you validate architecting’s conceptual learning Azure solutions. It’s just that some people prefer planning and then executing while the others prefer directly doing. There’s not much difference between both the exams. Only the focus and approach is different.
