Dell EMC Specialist – Systems Administrator, Unity XT — Question 99
What occurs immediately before the write is acknowledged to the host in a Dell PowerStore 1000T?
Answer options
- A. The peer node is updated.
- B. Data is passed through the deduplication and compression logic.
- C. I/O is saved within the node DRAM memory.
- D. Information is stored on the nonvolatile media of the NVRAM drives
Correct answer: C
Explanation
The correct answer is C because the I/O operations are temporarily stored in the node's DRAM memory before they are confirmed to the host. Options A, B, and D represent processes that occur either after the write acknowledgment or involve different stages of data handling that do not directly precede the acknowledgment.
