Dell EMC Associate – Information Storage and Management v4 — Question 55

What happens when the size of a write I/O request exceeds the configured write aside size in a block-based storage system?

Answer options

• A. Cache is bypassed and I/O is written directly to storage
• B. Write aside size is automatically reconfigured to the new write I/O size
• C. Warning message to reduce the size of write I/O is displayed
• D. Write data is lost and a re-write request is sent to the compute system

Correct answer: A

Explanation

When the write I/O request exceeds the configured write aside size, the system bypasses the cache and writes the I/O directly to storage, which is why option A is correct. Options B and C are incorrect because the write aside size does not automatically adjust, nor does a warning message prompt the user. Option D is also incorrect as the data is not lost; it is simply written directly to the storage.
