SG0-001 · Question #260
A two fabric merge has failed leaving you with segmented fabrics. Which could be the the cause of the segmented fabrics?
The correct answer is B. identical zone names. A two-fabric merge can fail, leaving segmented fabrics, if the merging fabrics contain identical zone names that define different sets of members.

Why each option
A two-fabric merge can fail, leaving segmented fabrics, if the merging fabrics contain identical zone names that define different sets of members.
Unique domain IDs are a requirement for a successful fabric merge, meaning that having unique IDs would facilitate a merge, not cause it to fail.
A Fibre Channel fabric merge will fail if two merging fabrics contain zones with the same name but different member lists, as this creates an unresolvable conflict regarding which zone definition should prevail. This conflict prevents the merge to maintain fabric integrity and prevent data corruption or unauthorized access, leading to fabric segmentation.
