Which of the following would MOST easily prevent zoning conflicts and fabric segmentation?

The correct answer is A. Ensure zoning information from a new storage switch is cleared before adding it to the fabric.. The administrator needs to prevent zoning conflicts and fabric segmentation when integrating a new storage switch into a Fibre Channel fabric.

Question

Which of the following would MOST easily prevent zoning conflicts and fabric segmentation?

Options

  • AEnsure zoning information from a new storage switch is cleared before adding it to the fabric.
  • BOnly configure zoning once at installation; reconfigure all switches if zoning must change.
  • CCreate separate fabrics as zoning can only be configured on one switch.
  • DConfigure zoning information on the HBA's not the storage switches.

Why each option

The administrator needs to prevent zoning conflicts and fabric segmentation when integrating a new storage switch into a Fibre Channel fabric.

AEnsure zoning information from a new storage switch is cleared before adding it to the fabric.Correct

Ensuring any existing zoning information on a new Fibre Channel switch is cleared before adding it to an existing fabric prevents conflicts. This allows the new switch to synchronize with the fabric's master switch and adopt the current, unified zoning configuration, thereby avoiding segmentation and maintaining fabric integrity.

BOnly configure zoning once at installation; reconfigure all switches if zoning must change.

Zoning configurations often require updates in dynamic environments; a policy of only configuring once or reconfiguring all switches for minor changes is impractical and inefficient.

CCreate separate fabrics as zoning can only be configured on one switch.

Zoning is a fabric-wide configuration applied across all switches in a Fibre Channel fabric, making the premise that zoning can only be configured on one switch incorrect and suggesting separate fabrics counterproductive.

DConfigure zoning information on the HBA's not the storage switches.

Zoning is a function performed by Fibre Channel switches to control device access within the fabric, not by Host Bus Adapters (HBAs), which are responsible for server-side connectivity.
