PK0-005 Practice Question: Basics of IT Infrastructure and IT Project Management
A project to implement a new storage solution. The team is evaluating iSCSI vs Fibre Channel. Which factor is most important for choosing iSCSI over Fibre Channel?
⚠ Common exam trap
Test-takers frequently assume iSCSI is chosen for its performance or distance capabilities, but the exam emphasizes that cost reduction from using existing Ethernet infrastructure is the primary driver for selecting iSCSI over Fibre Channel.
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
✓
Lower cost
iSCSI is generally chosen over Fibre Channel primarily because it leverages existing Ethernet infrastructure, which significantly reduces hardware and operational costs. Fibre Channel requires specialized switches, host bus adapters (HBAs), and cabling, whereas iSCSI can run on standard network interface cards (NICs) and switches, making it a more cost-effective solution for many organizations.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Longer distance support
Why it's wrong here
Both can support long distances with appropriate extensions; distance is not a primary factor.
- ✗
Higher performance
Why it's wrong here
Fibre Channel typically offers higher throughput and lower latency than iSCSI.
- ✗
Better security
Why it's wrong here
Security depends on implementation; iSCSI can use IPsec, but Fibre Channel has it own security mechanisms.
- ✓
Lower cost
Why this is correct
iSCSI leverages standard Ethernet switches and cables, reducing hardware costs.
