NetApp Certified Data Administrator (NCDA) – ONTAP SAN — Question 35

You just installed a new AFF A220 2-node cluster without additional disk shelves. When you review the Config Advisor output, you notice that your SAS cabling appears to be single-path HA.
In this scenario, which statement is true?

Answer options

• A. The Config Advisor version you are using requires a plugin for AFF controllers.
• B. AFF A220 controllers with internal disks support only single-path HA.
• C. Cable controller 1 0a to controller 2 0a, and cable controller 1 0b to controller 2 0b.
• D. Cable controller 1 0a to controller 2 0b, and cable controller 1 0b to controller 2 0a.

Correct answer: D

Explanation

The correct answer is D because this cabling setup allows for an active-active configuration, optimizing performance and redundancy. Option A is incorrect because no plugin is required for basic functionality, while option B is wrong since the A220 can support multi-path HA with proper cabling. Option C does not support optimal configuration for high availability.
