NS0-157 Question #134: Real Exam Question with Answer & Explanation
The correct answer is A: A LUN's QoS policies can be changed dynamically. Tests understanding of QoS policy group behavior, supported storage objects, and dynamic management capabilities in clustered Data ONTAP 8.2.
Question
Clustered Data ONTAP 8.2 or later Quality of Service (QoS) Policies have which three characteristics?
Options
- AA LUN's QoS policies can be changed dynamically
- BA QoS policy can be decreased
- CA QoS policy can be increased
- DA Qtree's QoS policies can be changed dynamically
- EA volume can be a member of two QoS policies
Explanation
Tests understanding of QoS policy group behavior, supported storage objects, and dynamic management capabilities in clustered Data ONTAP 8.2.
Common mistakes.
- D. Qtrees are not supported as members of QoS policy groups in clustered Data ONTAP 8.2; only volumes, LUNs, files, and SVMs are valid assignable objects for QoS policies.
- E. A storage object can belong to only one QoS policy group at a time in ONTAP; assigning an object to a second policy group replaces the existing assignment rather than allowing dual membership.
