350-601 Storage Network Practice Question
An organization uses FCIP to extend their SAN between two data centers over a 100 Mbps WAN link with 80 ms latency. The storage traffic includes large sequential writes. Which statement best describes the benefit of enabling compression on the FCIP tunnel?
⚠ Common exam trap
Cisco often tests the misconception that compression reduces latency, but candidates must remember that compression only improves throughput by reducing the amount of data sent, not the physical propagation delay.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Compression improves effective throughput over the WAN link
Enabling compression on an FCIP tunnel reduces the amount of data transmitted over the WAN link by compressing FC frames before encapsulation. For large sequential writes, this directly improves effective throughput because more actual storage data can be sent within the same 100 Mbps bandwidth, compensating for the high latency and low bandwidth.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Compression reduces end-to-end latency
Why it's wrong here
Compression introduces processing delay.
- ✓
Compression improves effective throughput over the WAN link
Why this is correct
Reduces data volume, so more data can be sent within the limited bandwidth.
- ✗
Compression is recommended only when the link has high packet loss
Why it's wrong here
Compression can exacerbate loss issues.
- ✗
Compression eliminates the need for jumbo frames
Why it's wrong here
Jumbo frames are still beneficial for large writes.
