PK0-005 Practice Question: Basics of IT Infrastructure and IT Project Management
An organization is deploying a new storage area network (SAN). Which of the following is a key consideration for ensuring high performance?
⚠ Common exam trap
It's easy for candidates to confuse storage capacity with performance, assuming more capacity means faster access, but the exam focuses on latency as the primary performance bottleneck in SAN deployments.
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
✓
Network latency
Network latency is a key consideration for SAN performance because SANs rely on low-latency, high-speed block-level storage protocols such as Fibre Channel (FC) or iSCSI. High latency can cause significant delays in I/O operations, directly impacting throughput and application responsiveness, especially in environments with synchronous replication or high transaction rates.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Network latency
Why this is correct
SAN performance depends on the storage network's ability to move frames with minimal delay; high latency between initiators and targets throttles throughput regardless of disk speed. Network latency is therefore the key performance consideration, directly affecting IOPS and response times in the deployed fabric.
- ✗
Cable color
Why it's wrong here
Cable colour is purely cosmetic labelling and has no bearing on throughput, latency or fabric redundancy. It is tempting because colour-coding genuinely aids identification and troubleshooting in dense patching cabinets, but it never determines SAN performance.
- ✗
Storage capacity
Why it's wrong here
Raw capacity determines how much data fits, not how fast it moves; performance hinges on IOPS, throughput and latency. It is tempting because capacity is the headline SAN purchasing metric, and running out of space is a real operational risk.
- ✗
Number of users
Why it's wrong here
User count affects capacity planning and licensing, not SAN throughput; performance depends on fabric bandwidth, IOPS and latency. It is tempting because concurrent user numbers genuinely size general-purpose file servers and application back ends where per-session load dominates.
