Question:
What is a read miss in cache operations?
- A. Deleting data from the cache
- B. Fetching data that is not in cache
- C. Fetching requested data that is already in cache
- D. Writing data to the cache
Answer: B
Explanation:
Aread missoccurs when the data requested by the host isnotavailable in the cache. As a result, the storage system must fetch the data from the slower disk storage (back-end), leading to higher latency.
* Cache hit:Data is already in cache # faster response.
* Cache miss (read miss):Data not in cache # fetched from the disk.

NEW QUESTION # 14
Question:
An Ethernet switch has eight ports, and all ports must be operational for 24 hours from Monday through Friday. However, failures of Port 6 occur within the week as follows:
* Tuesday: 6 AM to 8 AM
* Thursday: 5 PM to 10 PM
* Friday: 7 AM to 9 AMWhat is the MTBF (Mean Time Between Failures) of Port 6?
- A. 37 hours
- B. 32 hours
- C. 30 hours
- D. 40 hours
Answer: D
Explanation:
To calculate the MTBF, we need to determine the total operational time and the number of failures.
* Total operational time (Monday to Friday):5 days × 24 hours = 120 hours
* Number of failures:3 (Tuesday, Thursday, Friday)
MTBF = Total operational time / Number of failures
MTBF = 120 hours / 3 = 40 hours

What is the main advantage of a write-through operation in cache write I/O operations?
- A. Low risk of data loss
- B. Enhanced data security
- C. No impact to host I/O performance
- D. Reduced write-response time
Answer: B
Explanation:
Inwrite-through caching, data is written simultaneously to both the cache and the underlying disk. This ensures data integrity because the write is not acknowledged until it's safely written to the disk.
* Write-backcaching offers reduced latency but increases risk of data loss if cache is lost.
* Write-throughtrades speed for security, offeringenhanced data securityand reducing the risk of data loss during power failures.
