A database VM disk supports more throughput than measured, but the VM has reached its documented aggregate storage throughput limit. What should the architect evaluate first?

Choose the single best answer.

A.Only a faster disk, because VM throughput limits never constrain disk traffic
B.The VM's I/O limits and an appropriately sized VM/storage combination
C.More storage capacity without reviewing IOPS or throughput
D.Azure Blob archive to reduce disk read latency

Show the answer and explanation

✓ Correct answer

The VM's I/O limits and an appropriately sized VM/storage combination

Effective I/O is constrained by both disk and VM. A disk upgrade cannot bypass the VM cap. Archive is offline object storage, and capacity alone does not establish needed performance. Source guide: PDF page 27.
