The answer is to always activate the zone set using the 'zone activate' command in configuration mode, alongside using WWPN zoning for stability and read-only zone sets for audit purposes. These three practices form the core of Fibre Channel zoning best practices on Cisco MDS because WWPN-based zoning ensures persistent device identification regardless of physical port changes, while read-only zone sets prevent accidental configuration drift and provide a clear audit trail. On the Cisco DCCOR 350-601 exam, this topic tests your understanding of SAN security and operational stability, often appearing as a multiple-select question that tries to trap you into choosing soft zoning or assuming hard zoning is a separate best practice—remember, hard zoning is the default behavior, not an additional recommendation. A solid memory tip is to think "WAR": WWPN, Activate, Read-only—these three keep your SAN stable, enforced, and auditable.
350-601 Storage Network Practice Question
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.
Which THREE of the following are best practices for Fibre Channel zoning on Cisco MDS switches?
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.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Make zones as specific as possible, avoiding device inclusion across multiple zones unnecessarily
Zoning best practices: use WWPN zoning for stability, use read-only zone sets for audit, and minimize zone aliasing for clarity. Option A (hard zoning) is correct but not a best practice per se; hard zoning is default. The best practices are options B, C, and D. Option E (soft zoning) is less secure.
Key principle: Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
Make zones as specific as possible, avoiding device inclusion across multiple zones unnecessarily
Why this is correct
Specific zones reduce complexity and security risks.
Clue confirmation
The clue word "best" in the question point toward this answer.
Related concept
Authentication checks who the user is.
✓
Use WWPN-based zoning instead of port-based zoning
Why this is correct
WWPN zoning survives cable moves.
Clue confirmation
The clue word "best" in the question point toward this answer.
Related concept
Authentication checks who the user is.
✓
Always activate the zone set using the 'zone activate' command in configuration mode
Why this is correct
Ensures zones are applied.
Clue confirmation
The clue word "best" in the question point toward this answer.
Related concept
Authentication checks who the user is.
✗
Use hard zoning (access control list enforcement)
Why it's wrong here
Hard zoning is default but not a specific best practice; it's standard.
✗
Use soft zoning with name server response filtering
Why it's wrong here
Soft zoning is less secure than hard zoning.
Common exam traps
Common exam trap: authentication is not authorization
Logging in proves the user can authenticate. It does not automatically mean the user is allowed to enter privileged or configuration mode. Watch for AAA authorization, privilege level and command authorization details.
Detailed technical explanation
How to think about this question
This kind of question is testing the difference between identity and permission. A user may successfully log in to a router because authentication is working, but still fail to enter configuration mode because authorization is missing, misconfigured or mapped to a lower privilege level.
KKey Concepts to Remember
Authentication checks who the user is.
Authorization controls what the user is allowed to do after login.
Privilege levels affect access to EXEC and configuration commands.
AAA, TACACS+ and RADIUS can separate login success from command access.
TExam Day Tips
→Do not assume successful login means full administrative access.
→Look for words such as cannot enter configuration mode, privilege level, authorization or command access.
→Separate login problems from permission problems before choosing the answer.
Key takeaway
Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
Real-world example
How this comes up in practice
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. Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
What to study next
Got this wrong? Here's your next step.
Review Cisco AAA concepts — authentication, authorization, and accounting. Study privilege levels (0–15), command authorization under TACACS+, and how RADIUS differs. Then practise related 350-601 questions on access control and AAA configuration.

Variation 1. An engineer is designing a SAN for a virtualized environment. Which two best practices should be followed for Fibre Channel zoning?
medium
✓ A.Use single-initiator zoning.
B.Use multiple initiators in a single zone.
C.Use soft zoning exclusively.
D.Disable zoning for performance.
✓ E.Zone by WWPN rather than WWNN.
Why A: Single-initiator zoning (also known as one-to-one zoning) is a best practice because it restricts each Fibre Channel zone to exactly one initiator (host HBA) and one or more target ports. This eliminates the risk of RSCN storms propagating across multiple initiators, reduces fabric instability, and simplifies troubleshooting by ensuring clear, predictable paths between each host and its storage.
