Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Memory-to-vCore ratio.
The correct answers are B, C, and D. Gen5 and Premium-series hardware configurations for Azure SQL Database differ in memory-to-vCore ratio (B), IOPS and throughput limits (C), and compute generation/CPU architecture (D). Option A is incorrect because the number of vCores available is not a differentiating factor; both series offer a range of vCore counts. Option E is incorrect because both Gen5 and Premium-series support the Business Critical service tier.
