Pop quiz, hotshot! Are you preparing for CCNA Data Center certification? Take a minute to refresh your knowledge of Virtual Storage Area Networks (VSANs) with this question designed to test your knowledge of material likely to be found on the 200-150 DCICN exam.
Question: What are two attributes of a VSAN?
A. A VSAN defines a collision domain in a fiber channel network.
B. A VSAN creates fault isolation.
C. Broadcasts are flooded to all VSANs.
D. MAC address are used to communicate between devices within a VSAN.
E. VSANs can be broken up into zones for further security isolation.
Answer: B and E.
Explanation: A VSAN is a Virtual Storage Area Network (SAN). Each VSAN in this topology has the same behavior and property of a SAN. A VSAN has the following additional features:
- Multiple VSANs can share the same physical topology.
- The same Fibre Channel IDs (FC IDs) can be assigned to a host in another VSAN, which increases VSAN scalability.
- Every instance of a VSAN runs all required protocols such as FSPF, domain manager, and zoning.
- Fabric-related configurations in one VSAN do not affect the associated traffic in another VSAN.
- Events causing traffic disruptions in one VSAN are contained within that VSAN and are not propagated to other VSANs.
- You can define multiple zones in a VSAN. Zoning enables you to set up access control between storage devices or user groups.
