NS0-157 Question #153: Real Exam Question with Answer & Explanation

Question

Options

• Acapacity scaling, by allowing more than two storage systems to be combined with larger disk
• Benergy scaling, by allowing the cluster to share the same power source
• Cheterogeneous scaling, by allowing E-Series and FAS-Series systems within a single cluster
• Dnetwork scaling, by providing three or more network switches for the cluster network
• Eoperational scaling, by allowing the entire cluster to be administrated through a single resilient
• Fperformance scaling, by using Flash Cache, SSDs, and Quality of Service

Explanation

Storage administrators can scale clusters across three dimensions - capacity, operations, and performance. Options B, C, and D describe concepts that are either unsupported or not recognized scaling categories in clustered ONTAP.

Common mistakes.

• B. Energy or power scaling is not a recognized storage scaling category, and clusters do not share a single power source as a designed scaling mechanism.
• C. E-Series and FAS-Series systems run fundamentally different operating systems (SANtricity vs. ONTAP) and cannot be joined into a single clustered ONTAP cluster.
• D. Adding more network switches is an infrastructure design decision, not a named storage-scaling feature that administrators configure as part of a scaling strategy.
