NEW QUESTION # 29
Question:
A backup array was able to achieve a 30:1 reduction by finding multiple copies of the same data. Which method was used in this scenario?
- A. Data replication
- B. Data deduplication
- C. Data encryption
- D. Data compression
Answer: B
Explanation:
Data deduplication is a technique that eliminates redundant copies of data, storing only unique instances.
When multiple copies of the same data are found, deduplication replaces them with references to a single stored copy, significantly reducing storage requirements.
* Data replication:Involves copying data to another location for redundancy, not reducing storage size.
* Data encryption:Secures data but doesn't affect storage size.
* Data compression:Reduces data size by encoding information more efficiently but doesn't eliminate duplicates.
Reference:Dell Information Storage and Management Foundations 2023 Study Guide, Section: Data Deduplication and Data Archiving Solutions Architecture.
NEW QUESTION # 30
Question:
A customer uses FCIP to connect local and remote FC SANs. The remote SAN is replicated to and used to store daily backup data. Latency over the IP WAN increases to unacceptable levels during peak replication periods. No other data transfer services using the WAN experience the same latency problem.
What is the likely cause of the data replication performance issue?
- A. Ethernet frame segmentation
- B. IP packet segmentation
- C. FCIP gateway FC ports set to EX_Port mode
- D. FCIP gateway FC ports set to TE_Port mode
Answer: B
Explanation:
IP packet segmentationcan cause replication performance issues over the WAN.
Since FCIP tunnels FC frames over IP networks, if the IP packet size exceeds the MTU, packets are fragmented and reassembled, increasing latency.
* TE_Port modeis used for trunking, not related to packet fragmentation.
* EX_Port modeis used for inter-switch connectivity (FCR).
* Ethernet frame segmentationis not relevant in FCIP tunneling.

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. 40 hours
- B. 32 hours
- C. 37 hours
- D. 30 hours
Answer: A
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

- B. Fetching data that is not in cache
- C. Writing data to the cache
- D. Fetching requested data that is already in 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.
