NS0-157 Question #23: Real Exam Question with Answer & Explanation

The correct answer is A: CFO aggregates are given back first, then SFO aggregates are given back one at a time.. In clustered ONTAP HA giveback, CFO aggregates are returned first to restore the node's root volume and identity, followed by SFO aggregates returned one at a time.

Question

Which statement is true about CFO and SFO in clustered ONTAP?

Options

ACFO aggregates are given back first, then SFO aggregates are given back one at a time.
BSFO aggregates are given back first, then CFO aggregates are given back one at a time.
CAll aggregates are given at the same time.
DNone, clustered ONTAP supports SFO aggregates only.

Explanation

In clustered ONTAP HA giveback, CFO aggregates are returned first to restore the node's root volume and identity, followed by SFO aggregates returned one at a time.

Common mistakes.

B. SFO aggregates are not returned before CFO aggregates; the root aggregate contained in the CFO aggregate must be handed back first to establish the node's identity before data aggregates are relinquished.
C. Giveback is a staged, sequential process - not simultaneous - to prevent resource conflicts and ensure each aggregate and its volumes come online safely.
D. Clustered ONTAP supports both CFO and SFO aggregate types; CFO aggregates, particularly the root aggregate, are a fundamental component of each node's HA configuration.
