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.

AH3 resides in only one zone

H3 is a member of both Zone 1 and Zone 2 simultaneously, so it resides in more than one zone - not only one.

BH3 cannot access storage systems S1 and S2

H3 is a member of Zone 1 along with S1 and S2, so it can access both of those storage systems.

CZone 2 restricts data on S3 so that only H3 can access that dataCorrect

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.

DZone 1 and Zone 2 cannot belong to the same zone set

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.

EZone 1 provides access from all three hosts to storage systems S1 and S2Correct

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.
