A
Both teams would autoscale their work as data size evolves
B
Both teams would use the same source of truth for their work
C
Both teams would reorganize to report to the same department
D
Both teams would be able to collaborate on projects in real-time
E
Both teams would respond more quickly to ad-hoc requests
Explanation:
Explanation
The correct answer is B. Both teams would use the same source of truth for their work.
Why this is correct:
- Data Lakehouse Architecture: A data lakehouse combines the best features of data lakes and data warehouses, providing a unified platform where both data engineering and data analytics teams can work with the same data.
- Breaking Down Silos: The core problem described is "siloed nature" where data engineering and data analysis teams work in separate architectures. A lakehouse eliminates this by providing a single platform where both teams can access the same data.
- Single Source of Truth: With a lakehouse, both teams work from the same underlying data storage (the lakehouse), ensuring consistency and eliminating data duplication or synchronization issues.
Why other options are incorrect:
- A: Autoscaling is a technical feature, not a solution to organizational silos.
- C: Organizational restructuring is not a technical solution provided by a lakehouse architecture.
- D: While collaboration may improve, real-time collaboration is not the primary benefit of a lakehouse for breaking down silos.
- E: Faster response to ad-hoc requests is a potential benefit but not the core solution to siloed architectures.
Key Takeaway:
The fundamental value of a data lakehouse in this context is providing a unified platform where both data engineering and analytics teams can work with the same data, breaking down architectural silos and creating a single source of truth.
