EMC Proven Professional – Network Attached Storage Specialist — Question 20

In preparing a host to access its storage from VPLEX, what is considered a best practice when zoning?

Answer options

• A. Ports on host HBA should be zoned to either an A director or a B director.
• B. Each host should have at least one path to an A director and at least one path to a B director on each fabric, for a total of four logical paths.
• C. Dual fabrics should be merged into a single fabric to ensure all zones are in a single zoneset.
• D. Each host should have either one path to an A director or one path to a B director on each fabric, for a minimum of two logical paths.

Correct answer: D

Explanation

The correct answer is D because it ensures that every host has a minimum of two logical paths, enhancing redundancy and availability. Option A limits the host's connections to only one director, which is not ideal. Option B suggests an excessive number of paths, while option C proposes an unnecessary merging of fabrics that does not align with zoning best practices.
