NetApp Certified Implementation Engineer – ONTAP v3 — Question 12

You are configuring FC ports on front-end SAN switches for a 4-node MetroCluster configuration across two data centers. You need to ensure that each data center serves FC LUNs when a FC port goes offline in one data center.
In this scenario, which front-end switch setting must be modified to avoid overlap when a new port comes online?

Answer options

• A. NPIV enabled
• B. ANA mapped
• C. WWPN reject
• D. WWNN reject

Correct answer: C

Explanation

The correct answer is C, as enabling WWPN reject prevents the same World Wide Port Name (WWPN) from being used by multiple ports, ensuring no overlap occurs when a new port comes online. Options A and B do not specifically address the issue of WWPN conflicts, while D relates to World Wide Node Names (WWNN), which is not the primary concern in this scenario.
