Dell EMC Specialist – Systems Administrator, PowerEdge Server — Question 51

If a data reduction hardware I/O module fails, what happens to incoming data?

Answer options

• A. Data is written to disk without any data reduction
• B. Software-based reduction is used to reduce data
• C. Incoming data is held in cache until the failed hardware I/O module is replaced
• D. Hardware I/O module in the partner director within the engine is used to reduce data

Correct answer: D

Explanation

The correct answer is D, as the partner director's hardware I/O module can take over the data reduction process when one module fails. Option A is incorrect because data is not simply written to disk without processing; option B is wrong as software-based reduction is not the primary method in this scenario. Option C is also incorrect because data is not held in cache indefinitely; it is processed by the partner module.
