Quick Answer
The answer is Smart Zoning, as it is the only approach that meets the security requirement for host-to-LUN isolation while eliminating manual reconfiguration when new hosts are added. Unlike traditional zoning, which requires creating separate zones for each new initiator-target pair, Smart Zoning automatically enforces LUN masking by allowing multiple initiators and targets in a single zone while restricting access to only the paired relationships defined in the zone’s configuration. On the Cisco DCCOR 350-601 exam, this concept tests your understanding of efficient LUN access management in MDS fabrics, often appearing as a scenario where traditional zoning would create excessive zone objects and administrative overhead. A common trap is confusing Smart Zoning with VSAN zoning, which does not exist, or assuming FSPF handles access control—it does not, as FSPF is only a routing protocol. Remember the memory tip: “Smart Zoning pairs, not shares,” meaning it pairs initiators to targets within one zone instead of sharing access across all members.
This 350-601 practice question tests your understanding of storage network. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 is deploying a new storage network using Cisco MDS 9700 switches. They have multiple host servers and storage arrays. The security policy requires that each host can only access its own LUNs. The solution must be efficient and not require reconfiguration when new hosts are added. Which approach best meets these requirements?
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.
Traditional zone-based zoning with pWWNs
Why wrong: This requires manual zone creation for each new host, which is inefficient.
VSAN zoning
Why wrong: VSANs separate traffic at a higher level, not per initiator-target.
FSPF metric tuning
Why wrong: FSPF is for routing, not access control.
Smart Zoning
Smart Zoning reduces zone objects and simplifies management by automatically handling LUN masking.

Correct answer & explanation
Smart Zoning
Smart Zoning reduces the number of zone objects and simplifies management by automatically handling LUN masking based on initiator-target pairs. Traditional zoning would require manual zone creation for each new host. VSAN zoning is not a real concept, and FSPF is a routing protocol.
Key principle: Count usable hosts — not total addresses — and remember that the network and broadcast addresses are not available to hosts in standard IPv4 subnets.

Related concept
CIDR notation defines the prefix length.
Common exam traps
Subnetting questions often tempt you into counting all addresses. In normal IPv4 subnets, the network and broadcast addresses are not usable host addresses.
Detailed technical explanation
Subnetting questions test whether you can identify the network, broadcast address, usable range, mask and correct subnet. Slow down enough to calculate the block size correctly.
Key takeaway
Count usable hosts — not total addresses — and remember that the network and broadcast addresses are not available to hosts in standard IPv4 subnets.
Real-world example
A network engineer segments a warehouse floor into three subnets: 20 scanners, 5 printers, and 2 management hosts. Picking the wrong mask wastes addresses or leaves too few usable hosts. Exam questions test whether you can apply CIDR notation, calculate block size, and identify the correct usable-host range for a given prefix.
What to study next
Review block sizes, usable host formulas (2^n − 2), and how to find network and broadcast addresses for /24 through /30. Then practise related 350-601 subnetting questions on CIDR, address ranges, and subnet selection.
