質問 # 76
To protect against an on-site disaster, which NetApp protection method should an administrator use to provide a Zero RTO for applications in a SAN environment?
正解：A
解説：
SnapMirror active sync is the ONTAP data-protection technology designed to provide Zero Recovery Time Objective for business-critical SAN applications. It synchronously replicates protected application data between ONTAP clusters and uses host multipathing plus ONTAP Mediator-assisted automatic failover so that application access can continue when the primary storage system or site becomes unavailable. NetApp explicitly describes SnapMirror active sync as providing Zero RTO or Transparent Application Failover for SAN environments. SnapMirror asynchronous cannot provide Zero RTO because replication is not continuously synchronous and recovery requires a failover workflow. SnapMirror SVM and FlexClone LUNs also do not provide the same automatic, synchronous application failover behavior. Relevant SAN ONTAP topics are SnapMirror active sync, synchronous replication, consistency groups, ONTAP Mediator, automatic failover, and SAN business continuity.

A customer has a 10GB volume with an 8GB LUN that is using 7GB. The snapshot policy is hourly and retains 48 snapshots. After a ransomware attack that encrypts all files on the LUN, the customer notices that all snapshots are gone.
What could cause this behavior?
正解：B
解説：
The likely cause for the disappearance of all snapshots after a ransomware attack that encrypted all files on the LUN is the Snapshot autodelete feature. When the volume becomes full due to the encryption, the autodelete feature removes older snapshots to free up space, preventing the volume from running out of space and ensuring write operations can continue.
For more information, see:
* NetApp Documentation on Snapshot Autodelete
* NetApp Community Discussion on Snapshot Deletion
質問 # 78
A customer has onboarded a new application that is based on SAN, and they need to present additional storage to an FCP SAN host.
Which two tasks must be performed on the storage cluster to present the storage? (Choose two.)
正解：A、C
解説：
For an FCP SAN host, the storage object to present is a LUN, and host access is controlled by mapping that LUN to an initiator group. NetApp's SAN provisioning workflow creates the LUN, creates or selects an igroup containing the host's FC WWPNs, and then creates the LUN mapping. A namespace and subsystem are NVMe constructs, not the objects used to present conventional SCSI LUN storage over FCP. Therefore, creating a namespace or mapping storage to an NVMe subsystem would not satisfy the stated FCP requirement. The question assumes the FCP SVM and host connectivity already exist; the required storage- side actions are to provision the new LUN and map it to the appropriate igroup. Relevant SAN ONTAP topics are FCP provisioning, LUN creation, igroups, WWPN-based host access, and LUN mapping.
質問 # 79
A customer is migrating FC-mounted VMFS datastores using SnapMirror from their existing NetApp ONTAP cluster to their new ONTAP cluster.
After breaking the SnapMirror relationship on the destination cluster, what does the customer need to do before mapping the LUN to the VMware hosts?
正解：C
解説：
For an FC-attached VMware VMFS datastore migrated through SnapMirror, maintaining the expected LUN identity is critical when presenting the replicated LUN from the destination cluster. VMware uses persistent SCSI device identifiers associated with the LUN, including its serial-based identity, when recognizing an existing VMFS device. ONTAP provides the lun modify -serial capability specifically to modify a LUN serial number. Therefore, after the SnapMirror destination is made writable, the destination LUN ' s serial number must be configured appropriately before the LUN is mapped back to the VMware initiators. Creating a FlexClone, restoring from a Snapshot copy, or changing the LUN OS type does not address device identity.
Relevant SAN ONTAP topics include SnapMirror SAN migration, LUN identity, LUN serial numbers, VMware VMFS, and LUN mapping.
質問 # 80
An administrator has a two-node NetApp ONTAP cluster that is hosting FC LUNs for 90 SAN hosts. The hosts are experiencing occasional performance problems and receiving QFULL responses from the cluster nodes.
Which action would resolve this issue?
正解：A
解説：
A QFULL response indicates that the storage controller's FC target-port command queue has reached its supported capacity and cannot accept additional SCSI commands. With 90 hosts generating I/O, excessive fan- in to the existing target ports can exhaust available queue resources. Configuring additional FC target ports allows host connections and queued commands to be distributed across more storage-side target resources, reducing pressure on each individual target port. Increasing initiator queue depth would worsen the condition because hosts could submit more outstanding commands. Similarly, increasing target-port queue depth is not the appropriate administrator-controlled remedy presented here because the physical target adapter has defined queue limits. NetApp recommends planning host fan-in carefully to avoid QFULL conditions.
Relevant topics include FC queue depth, target-port fan-in, QFULL responses, SAN scalability, and FC target- port design
