NEW QUESTION # 45
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 TE_Port mode
- B. FCIP gateway FC ports set to EX_Port mode
- C. Ethernet frame segmentation
- D. IP packet segmentation
Answer: D
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.
