A file migration contains millions of tiny files. A size-divided-by-link-rate estimate fits the window, but a pilot runs much slower. Which factor should be investigated first?

Choose the single best answer.

A.Only the advertised WAN bandwidth, without considering metadata operations
B.Only database CPU sizing, without examining the file enumeration or target operations
C.Enumeration and per-file operation-rate overhead
D.The target storage redundancy setting alone, without a per-file throughput pilot

Show the answer and explanation

✓ Correct answer

Enumeration and per-file operation-rate overhead

Enumeration, metadata work, and operations per second can limit many-small-file migrations. Advertised bandwidth alone ignores those effects. Database CPU sizing does not identify the file-copy bottleneck. Storage configuration may affect performance, but redundancy alone does not explain or measure per-file overhead.
