01. Both nodes of an HA pair suddenly log a burst of cluster-communication errors, and moments later one node performs a takeover of its partner.
Which back-end component is the most likely cause?
a) A fault on the cluster interconnect link
b) A fault in the export policy rules
c) A fault in the Snapshot schedule
d) A fault in the S3 bucket policy
02. You are documenting the interconnect topology for a two-node system that has no dedicated cluster switches in the rack.
What distinguishes a switchless cluster interconnect from a switched one?
a) The two nodes switch to synchronous mirroring
b) The two nodes connect directly without cluster switches
c) The two nodes operate without NVRAM mirroring
d) The two nodes lose their HA takeover capability
03. Following an automatic MetroCluster switchover, an affected aggregate comes back online at the surviving site but reports a degraded, unmirrored state.
What is the most likely reason?
a) The QoS ceiling on the aggregate was lowered
b) The DNS server for the cluster is unreachable
c) The failed site's mirrored plex is unavailable
d) The export policy on the volume was changed
04. A controller will not boot ONTAP, yet you are still able to reach its SP/BMC and drive diagnosis from there.
Why is the SP/BMC useful specifically in this situation?
a) It caches recent client reads to reduce access latency
b) It runs independently of ONTAP and stays reachable
c) It stores the node's data aggregates and metadata locally
d) It holds the cluster quorum and epsilon for consensus
05. During onboarding, a customer asks which capabilities the Service Processor on their controllers actually provides.
Which of these does the SP provide?
a) Remote console with power control and environmental monitoring
b) LUN masking and igroup mapping for connected hosts
c) Inline block deduplication and compression of stored data
d) Scheduling and retention of periodic Snapshot copies
06. A single user is denied access to one NFS file, while other users open the same file and that same user opens other files in the volume without any problem. The network path and the volume itself are healthy.
Which two areas are the most relevant to investigate for this narrow, user-specific denial?
(Choose two.)
a) The disk firmware and shelf hardware hosting the volume
b) The export policy rule that applies to that user's client
c) The name mapping and security style resolved for that user
d) The MetroCluster mediator that arbitrates site failover
07. Each ONTAP volume is assigned a security style of UNIX, NTFS, or mixed.
What does that security style determine for the files in the volume?
a) Which RAID level protects the disks in the hosting aggregate
b) Which network MTU applies to the data LIFs serving the volume
c) Which Snapshot schedule captures point-in-time copies of the volume
d) Which permission model governs access to the volume's files
08. Clients at one remote site report high latency, while local clients on the same cluster are unaffected and the array itself is lightly loaded during the same period.
Which layer is the most suspect?
a) The RAID layer, where a degraded group and rebuild add delay.
b) The network path, where round-trip time and retransmits add delay.
c) The WAFL layer, where write allocation could be stalling.
d) The NVRAM layer, where log draining could be stalling.
09. After off-box virus scanning with Vscan is enabled on a NAS SVM, users begin reporting noticeably slower file opens. The storage system itself shows healthy capacity and no controller alerts.
Where is the added latency most likely originating?
a) The aggregate parity recalculating across the RAID group
b) The external Vscan servers responding slowly to scan requests
c) The export policy re-evaluating rules for each file request
d) The cluster epsilon shifting between nodes in the cluster
10. In a multiprotocol share serving both NFS and SMB, a Windows user tries to open a file that a UNIX user created earlier. Some Windows users can open it and some cannot.
Whether the Windows user is granted access depends most directly on which pair of settings?
a) The Snapshot policy and its associated retention schedule
b) The network MTU setting and the placement of the data LIF
c) The hosting aggregate and its underlying plex layout
d) The volume security style and the user name mapping configuration
