This 350-601 practice question tests your understanding of storage network. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company wants to consolidate multiple physically separate Fibre Channel SANs into one switch infrastructure while keeping each SAN's traffic isolated. Which technology best achieves this?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "best"
Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
Reduce the number of switches by using a single director
Why wrong: Does not isolate traffic; VSANs do.
Virtual SANs (VSANs)
VSANs create isolated logical fabrics over a physical infrastructure.
Use a single VSAN with extensive zoning
Why wrong: Zoning alone does not provide the same isolation as VSANs.
Deploy separate physical cabling for each SAN
Why wrong: Defeats consolidation goal.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Virtual SANs (VSANs)
VSANs (Virtual SANs) allow multiple physically separate Fibre Channel SANs to be consolidated onto a single switch infrastructure by creating isolated virtual fabrics. Each VSAN maintains its own fabric services, such as name server and zone server, ensuring traffic isolation without requiring separate physical switches or cabling.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Reduce the number of switches by using a single director
Why it's wrong here
Does not isolate traffic; VSANs do.
Virtual SANs (VSANs)
Why this is correct
VSANs create isolated logical fabrics over a physical infrastructure.
Clue confirmation
The clue word "best" in the question point toward this answer.

Why it's wrong here
Zoning alone does not provide the same isolation as VSANs.
Deploy separate physical cabling for each SAN
Why it's wrong here
Defeats consolidation goal.
Common exam traps
Cisco often tests the misconception that zoning alone provides the same isolation as VSANs, but zoning only controls device access within a single fabric, whereas VSANs provide complete fabric-level separation including separate control planes and fabric services.
Detailed technical explanation
VSANs operate by assigning each port to a specific VSAN ID (1–4095, with 1 being the default), and each VSAN runs its own instance of Fibre Channel services like Fabric Login (FLOGI), Name Server (NS), and Zone Server. This ensures that events in one VSAN, such as a reconfigure fabric (RCF) or a fabric-wide disruption, do not affect other VSANs. In a real-world scenario, a company could merge production, backup, and test SANs into one physical fabric using VSANs, reducing hardware costs while maintaining strict isolation.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A practitioner preparing for the 350-601 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
