Dell EMC Exam DEA-1TT5 Topic 1 Question 28 Discussion

Actual exam question for Dell EMC's DEA-1TT5 exam

Question #: 28
Topic #: 1

A customer uses FCIP to connect local and remote FC SANs. The remote SAN is continuously replicated to, and used to store

daily backup dat

a. 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?

AIP packet segmentation

BFCIP gateway FC ports set to EX_Port mode

CEthernet frame segmentation

DFCIP gateway FC ports set to TE_Port mode

Show Suggested Answer

Suggested Answer: A

When an Ethernet frame is larger than the maximum transmission unit (MTU) of a link, it must be fragmented into smaller pieces, which are sent separately and reassembled at the receiver. This is known as IP packet segmentation. Fragmentation and reassembly of the IP packets can add significant latency and can cause performance issues for FCIP. In this scenario, the issue is specific to data replication, indicating that the issue is with the FCIP configuration or the replication application. The other options, B, C, and D, are unrelated to the issue.
