1. What does a reference architecture provide?
Question 1A. A detailed, project-specific design customised for a single solutionB. A high-level diagram representing the structural pattern of a solution, giving a consistent framework for similar projects across an organisationC. A list of every server and its IP addressD. A budget forecast for a technology programmeE. A record of past project failures
2. How does a reference architecture differ from a solution architecture?
Question 2A. Reference architecture is customised for each project; solution architecture is genericB. They are identical documents produced at different timesC. Reference architecture is a generalised template aligned with best practices, while solution architecture is customised for each projectD. Solution architecture is only for business stakeholders; reference architecture only for engineersE. Reference architecture covers hardware only; solution architecture covers software only
3. Which of the following is NOT listed as a benefit of a reference architecture?
Question 3A. Ensuring consistency across solutionsB. Reducing redundancyC. Accelerating solution delivery with a clear blueprintD. Eliminating the need for any data governanceE. Aiding risk management through tried-and-tested design patterns
4. In a data and AI cognitive (DAC) reference architecture, what is the role of the landing zone?
Question 4A. A centralised area where raw data is ingested and stored temporarily, acting as a buffer before more structured layersB. The final layer where dashboards and reports are delivered to usersC. The layer where machine learning models are trainedD. A logical view of data that avoids physically moving itE. The layer that enforces regulations and audit logs
5. In a DAC reference architecture, in which component does data undergo preliminary cleaning and transformation to ensure consistency and completeness before advancing through the pipeline?

Question 9A. Azure Data Factory and Google BigQueryB. Amazon Redshift and Google BigQueryC. Tableau, Power BI or custom web applicationsD. MySQL and PostgreSQLE. MongoDB and Cassandra
10. From a business perspective, how does a reference architecture serve stakeholders?
Question 10A. It replaces the need for any technical teamB. It provides line-by-line code for developersC. It sets the pricing of the final productD.
