200-150 · Question #204
Refer to the exhibit. Which two statements accurately describe the hosts, storage systems, and zones in the storage architecture'? (Choose two.)
The correct answer is C. Zone 2 restricts data on S3 so that only H3 can access that data E. Zone 1 provides access from all three hosts to storage systems S1 and S2. SAN zones define access boundaries between hosts and storage targets, and a single zone set can contain multiple zones with overlapping members.

Why each option
SAN zones define access boundaries between hosts and storage targets, and a single zone set can contain multiple zones with overlapping members.
H3 is a member of both Zone 1 and Zone 2 simultaneously, so it resides in more than one zone - not only one.
H3 is a member of Zone 1 along with S1 and S2, so it can access both of those storage systems.
Zone 2 is configured with only H3 and S3 as members, so the Fibre Channel fabric enforces that S3 is accessible exclusively by H3 and no other initiator. This targeted access restriction is the primary purpose of SAN zoning.
Multiple zones can belong to the same zone set - a zone set is simply an activated grouping of zones and imposes no restriction on mixing zones together.
Zone 1 is configured with all three hosts (H1, H2, H3) and storage systems S1 and S2 as members, which grants every host in that zone the ability to communicate with both storage targets.
