NetApp NS0-516 (NCIE SAN Specialist E-Series) Sample Questions:

01. Support has asked the engineer to gather diagnostic data so a recent array fault can be analyzed off-site.
Which items belong in the collected support bundle?
(Choose three.)
a) The major event log recording array events over time
b) The fabric switch vendor's firmware upgrade installation package
c) A full disk image of the attached host's operating system
d) A state capture of the array's current internal state
e) The AutoSupport data set generated for the array
 
02. A storage array reports a Needs Attention status with an amber fault indicator on the shelf. The engineer wants both a diagnosis of the fault and the recommended corrective steps.
Which SANtricity function should the engineer open first?
a) The AutoSupport scheduler, which controls when dispatches are sent to support
b) The volume copy manager, which tracks the progress of copy pair jobs
c) The performance monitor, which graphs controller IOPS, latency, and throughput
d) The hardware inventory report, which lists installed drives and modules
e) Recovery Guru, which reports the detected fault and its recovery procedure
 
03. Before any hardware is ordered, an engineer must translate the customer's capacity and performance targets into a proposed E-Series configuration.
Which tool is intended for this design task?
a) SANtricity Unified Manager, which centrally manages arrays that are already deployed in production
b) A sizing and design tool that models capacity and performance to propose a configuration
c) The audit log, which captures administrative changes after go-live
d) A CA-signed certificate, which secures management connections to the array
 
04. All paths to a mapped volume are present and both controllers are online, yet SANtricity shows nearly all host I/O traversing non-optimized paths, degrading performance.
What is the most likely cause?
a) The host mapping for the owning controller was removed
b) A single SFP has failed, forcing all traffic onto one surviving link
c) The host type is set incorrectly, so ALUA path priorities are not honored
d) The Volume Group is rebuilding after a recent drive failure
e) The array controller firmware predates the host's HBA firmware, breaking supported interoperability
 
05. Several hosts attached to the same array report I/O errors at the same moment, while hosts connected to a different array are unaffected.
Following a structured isolation approach, where should the engineer begin?
a) At the individual HBA firmware level on a single attached host
b) At the segment size and cache settings of each affected volume
c) At the host mapping of one volume to one of the hosts
d) At one host's local multipath driver configuration file and its device rescan behavior
e) At the layer common to all affected hosts — the fabric and the array controllers
 
06. A team needs a complete, standalone copy of a production volume to migrate a workload to different drives. The copy must remain fully intact even if the source volume is later deleted.
Which feature is appropriate, and why is a Snapshot unsuitable here?
a) Synchronous Mirroring, because its remote replica survives deletion of the source
b) Snapshot, because it is space-efficient and remains valid after the source is deleted
c) Volume Copy, because it is a full, independent copy that does not depend on the source volume
d) Asynchronous Mirroring, because its periodic images detach from the source over time
 
07. Deployment is complete, and the engineer is assembling the package handed to the customer so they can operate and support the array.
Which items belong in that post-deployment handover?
(Choose three.)
a) The vendor's internal engineering defect backlog for the platform
b) The as-built record showing how pools and host mappings were actually configured
c) Management IP addresses and the initial credentials for the array
d) Confirmation that AutoSupport is configured for support case telemetry
e) The customer's future procurement budget for additional shelves
 
08. A dual-controller array is cabled to a host through two independent fabrics, but the host's multipath output shows only half the expected number of paths.
Which two checks should the engineer perform first?
(Choose two.)
a) Disable read caching on the owning controller to reduce path load
b) Verify that zoning presents both controllers' target ports to the host in each fabric
c) Delete and recreate the volume group to refresh the path table
d) Increase the volume's segment size so that host I/O is spread across a larger set of back-end drives
e) Confirm the host's multipath driver is installed and configured for the array
 
09. Two servers must both access the same set of volumes with a consistent LUN number for a shared-storage application.
Which E-Series construct is designed for this requirement?
a) A host cluster that groups the hosts so a single mapping presents each volume to every member.
b) A separate host mapping per server, each using a different LUN number.
c) A single host object that lists both servers' initiator addresses together.
d) A dedicated owning controller assigned to each server individually.
 
10. A drive in a RAID 6 Volume Group fails, and an available hot spare is integrated automatically. During reconstruction the volumes remain online but throughput drops.
Which statement best describes this situation?
a) A second drive failure during the rebuild would always be survivable
b) The volumes are offline until the failed drive is physically replaced by hand
c) Reconstruction requires deleting and recreating each affected volume first
d) The group is rebuilding onto the spare; volumes stay online with reduced performance
e) The array halts all host I/O to the group until the rebuild completes
