SG0-001 · Question #509
Which of the following is the purpose of VLAN technology?
The correct answer is B. It allows for segregation of traffic within a physical network.. VLAN technology segments a single physical network into multiple isolated logical networks, enabling traffic segregation.
Question
Which of the following is the purpose of VLAN technology?
Options
- AIt allows FCoE to act like an iSCSI SAN.
- BIt allows for segregation of traffic within a physical network.
- CIt allows iSCSI SANs to function as FCP SANs.
- DIt allows a physical network to behave as if it is a VSAN.

Why each option
VLAN technology segments a single physical network into multiple isolated logical networks, enabling traffic segregation.
VLANs do not convert FCoE into an iSCSI SAN; these are distinct storage networking protocols with different underlying mechanisms.
VLANs (Virtual Local Area Networks) logically segment a physical network into separate broadcast domains, allowing different types of traffic or different departments to operate on isolated networks while sharing the same physical infrastructure. This improves network performance, security, and manageability.
VLANs do not enable iSCSI SANs to function as FCP SANs; these are separate and incompatible storage access methods.
VLANs provide logical segmentation of a physical LAN but do not make it behave as a VSAN, which is a Fibre Channel concept for virtual SANs.
