NS0-157 Question #341: Real Exam Question with Answer & Explanation
The correct answer is C: The surviving partner returns ownership of the root aggregate first followed by the other. During storage failover giveback, aggregate ownership is returned in a specific sequence to ensure the recovered node initializes correctly before data access resumes.
Question
Which of the following statements is true about giveback with storage failover?
Options
- AThe surviving partner returns ownership of all the aggregates all at the same time to its partner
- BThe surviving partner returns ownership of the all the aggregates and the data LIFS to its partner
- CThe surviving partner returns ownership of the root aggregate first followed by the other
- DI/O only resumes when all aggregates are returned to the partner node
Explanation
During storage failover giveback, aggregate ownership is returned in a specific sequence to ensure the recovered node initializes correctly before data access resumes.
Common mistakes.
- A. Aggregates are not returned simultaneously; the root aggregate must be returned first to allow the node to reach an operational state before data aggregate ownership transfers.
- B. Data LIFs are not part of the aggregate giveback sequence; LIF migration is a separate process that ONTAP manages independently of aggregate ownership transfers.
- D. I/O resumes on a per-aggregate basis as each aggregate is given back, so clients can access data progressively rather than waiting for all aggregates to be returned.
