Question:
In traditional provisioning, which two factors determine the availability, capacity, and performance of the RAID set?
- A. Make of drives
- B. Capacity of drives
- C. The number of drives in the RAID set
- D. The RAID level
Answer: C,D
Explanation:
In traditional storage provisioning, the RAID configuration significantly impacts the storage system's characteristics:
* RAID Level: Determines data redundancy and fault tolerance. For example, RAID 1 mirrors data, providing high availability, while RAID 5 uses parity, balancing performance and redundancy.
* Number of Drives: Affects both capacity and performance. More drives can increase total storage capacity and improve performance through parallel data access.

NEW QUESTION # 26
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. FCIP gateway FC ports set to EX_Port mode
- B. Ethernet frame segmentation
- C. IP packet segmentation
- D. FCIP gateway FC ports set to TE_Port mode
Answer: C
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.
