Which three statements about zoning are correct? (Choose three.)

Question

Options

• AZoning increases security.
• BDNS queries are used for software zoning.
• CSoftware zoning is more secure than hardware zoning.
• DWhen using zones and VSANs together, the zone is created first.
• EZoning requires that VSANs be established before it becomes operational.

• A
  90% (27)
• C
  3% (1)
• D
  7% (2)

Explanation

Zoning in SANs increases security (A) by restricting which initiators (hosts) can communicate with which targets (storage), preventing unauthorized access and reducing the blast radius of misconfigurations or failures. Software zoning (B) uses Fibre Channel Name Server (DNS - Directory Name Service in FC terminology) queries to enforce zone membership; devices query the name server to discover which targets they are permitted to access. VSANs must be established before zoning becomes operational (E) because zones exist within a VSAN context - you must first define the VSAN, then create zone sets within it. Choice C is incorrect - hardware zoning (enforced at the ASIC/port level) is more secure than software zoning because it cannot be bypassed by a compromised host. Choice D is incorrect - the correct order is VSAN first, then zone creation within that VSAN, not zone first.
