NO.1 You want to create a data volume on aggr0 and you receive a message with the following
warning:
''Warning: You are about to create a volume on a root aggregate. This may cause severe performance
or stability problems and therefore is not recommended. Do you want to proceed?''
What is the reason for this severe performance or stability problem?
A. Controller failover and storage failover are separate processes that must occur at different times,
otherwise problems will arise.
B. The performance load generated by the data volume can be very strong, so it should not be shared
with vol0 on aggr0, requiring a separate aggregate for it.
C. Controller failover and storage failover are separate processes that must occur in parallel,
otherwise problems will arise.
D. The performance load generated by the vol0 cannot be shared with any other volume on aggr0,
requiring a dedicated aggregate for it.
Answer: B
Explanation:
One possibly cause is Disk I/O contention on the data volume. The root volume in Cluster-Mode is
used to store and update various tables of the replicated database. Crucial information regarding the
locations of LIFs, volumes, aggregates, and different jobs required to run in the cluster are stored in
these tables. If a root aggregate has very busy data volumes, the disks in the aggregate will
experience higher latency. When a node is unable to update its copy of the replicated database fast
enough, it will consider itself unhealthy and stop serving all the data until it can catch up. This is
extremely disruptive and affects all the volumes on the node, even if the cause is related to the data
volumes stored on the root aggregate only.
Reference:
Why is a warning displayed when attempting to create one or more data volumes in the root
aggregate in Data ONTAP Cluster-Mode?

NO.2 A customer learns that a certain NetApp tool allows remote data collection, intelligent core file
handling, and notification of down storage controllers for technical support analysis and
troubleshooting.
What is the name of this tool?
A. Synergy
B. HW Assist
C. RSA
D. HWU
Answer: C

NS0-180参考書   
Explanation:
Remote Support Agent (RSA) is a remote diagnostics data collector that is embedded directly into the
storage controller's remote management device firmware. Remote Support Agent enables a NetApp
support engineer to remotely request an automated upload of log files, core files, and other
diagnostic information stored in the storage controller and to remotely trigger an on-demand
AutoSupport collection. Incorrect: Not B: The Hardware Universe (HWU) application is NetApp's
system configuration solution. Not C: NetApp Synergy is a complete design, deployment and
documentation tool. The program enables you to build a very accurate, detailed model of a NetApp
storage system. You can represent most aspects of a storage deployment including the hardware
configuration and the sizing of all storage containers, including aggregates, volumes, qtrees and
LUNs.
