EMC Proven Professional – Information Storage Associate — Question 1

A new VPLEX cluster has been configured. However, you are unable to register any host initiators. After verifying that the host has been properly zoned to the
VPLEX cluster, you still cannot register them. What is a possible cause?

Answer options

• A. Front end ports have not been enabled.
• B. Back-end ports have not been enabled.
• C. Back-end arrays have not presented any LUNs.
• D. Storage View for host has not been created.

Correct answer: C

Explanation

The correct answer is C because if back-end arrays haven't presented any LUNs, the host initiators won't have any storage to access, making registration impossible. Options A and B are incorrect as the problem specifically relates to the back-end arrays, not the front-end or back-end ports. Option D is also incorrect since the absence of LUN presentation is the main issue, not the creation of a Storage View.
