NetApp Certified Data Administrator (NCDA) – E-Series — Question 58

A customer has four or more nodes in a cluster. More than four target ports are being used by the SVMs in any node. The customer wants to limit the number of paths that can be used to access LUNs on the nodes, so that the paths do not exceed the recommended maximum of eight.
In this scenario, which three actions will accomplish this task? (Choose three.)

Answer options

• A. Use ALUA protocol.
• B. Use multipathing software.
• C. Use port sets for iSCSI.
• D. Use Selective LUN Mapping
• E. Use FC switch zoning.

Correct answer: C, D, E

Explanation

The correct measures—using port sets for iSCSI (C), Selective LUN Mapping (D), and FC switch zoning (E)—effectively manage and limit access paths to LUNs. ALUA protocol (A) and multipathing software (B) do not directly limit the number of paths but instead manage them, which does not address the requirement to stay within the maximum of eight paths.
