Question1: You configured iSCSI multipathing on a Windows host to a 2-node ONTAP cluster so that you can attach to some LUNs. You see that the host logging in to both iSCSI LIFs in the ONTAP cluster, and you notice that the igroup is correctly set. After you open Disk Management and rescan for disks, the NetApp LUNs do not show up.
In this scenario, what should be performed to enable the LUNs to be visible to the Windows host?

Question2: Your customer added a new DS2246 shelf to an existing stack on their FAS8060A system. The customer then noticed that the new shelf's disks appear with the shelf serial number instead of the shelf ID in the sysconfig -rcommand output.
What is the reason for this problem?

Question3: You want to determine which SMB versions that a CIFS server can use when communicating with external servers.
Which two CIFS server settings should be reviewed to accomplish this task? (Choose two.)

Question4: Two weeks ago, your customer experienced a data outage, which caused their MCC to switch over. When the power was restored, they found that 14 disks over three RAID groups had failed, which caused two data aggregates to lose their mirror plexes.
In this situation, before you perform a switchback, which three actions should be taken? (Choose three.)

Question5: Click the exhibit button.

A customer notifies you that Active IQ is showing a warning that a broadcast domain in their environment has been configured with ports from multiple VLANs.
Referring to the exhibit, which two statements are correct? (Choose two.)

Question6: A customer is attempting to move from NFSv3 to NFSv4.x and reports that all attempts to mount using NFSv3 continue to be successful, however, all of their NFSv4.x mount attempts fail with an "access denied" error.
Which two statements would cause this error? (Choose two.)

Question7: A customer has created an interface group (igroup) named a0a, a VLAN named a0a-2500, and a data LIF associated with the VLAN interface that has been assigned an IP of 10.254.10.100. The customer is able to ping 10.254.10.100 from a Windows client without any issues, but data traffic is not working.
In this scenario, what is the solution to the problem?

Question8: A reboot was performed by a watchdog reset on the node.
In this scenario, which statement is true?

Question9: End users are complaining of high latency when accessing an ONTAP cluster.
Which command helps you to determine whether there is a storage component that is contributing to this problem?

Question10: Click the exhibit button.

Your customer added a new DS4246 shelf to their FAS system. They created an aggregate on the new shelf. Two weeks later, they log in to Active IQ and discover the Medium Impact error shown below.
"Both SAS connections from one controller go to the same shelf."
Referring to the exhibit, which statement is correct?

Question11: Click the exhibit button.

Your customer is calling about their MetroCluster environment. They have provided you with the output of the metrocluster interconnectadapter showcommand.
Referring to the exhibit, which statement is correct?

Question12: Click the exhibit button.

A storage administrator reports that when they enabled Vscan, they began receiving reports of CIFS users having very slow access to all their files. The storage administrator recovered from the issue by disabling Vscan on their SVM. The storage administrator was able to collect perfstat output during the time of the reported slow access, as shown in the exhibit.
In this situation, what is the problem?

Question13: The error message shown below is reported in the EMS log file.
"[sis.changelog.full:warning]: Change logging metafile on volume DATA1 is full and can not hold any more fingerprint entries." What are two ways to solve this problem? (Choose two.)

Question14: Click the exhibit button.

A customer's system reported several errors. There was no disruption, but the customer is concerned about the system's health.
Referring to the exhibit, which statement is true?

Question15: After you replaced the motherboard, the node stopped in the "waiting for the cluster application to come online" state.
Which two actions should you perform to troubleshoot this problem? (Choose two.)

Question16: A customer has requested your assistance with replacing a DS224C disk shelf from their cluster nondisruptively.
Which two actions should be performed before physically replacing the shelf? (Choose two.)

Question17: A customer reports that OnCommand Performance Manager shows that the workload on node-02 in a 4- node cluster has increased to a level that is higher than the threshold. The customer wants to avoid this issue becoming a performance problem.
Which two actions would result in achieving this goal? (Choose two.)

Question18: A customer reports that copying data over iSCSI attached LUNs is taking significantly longer than usual.
The customer asks you to help to identify the root cause of this problem.
Which two perfstat sections would you use to accomplish this task? (Choose two.)

Question19: At a customer site, the storage failover givebackcommand fails when giving back the root aggregate.
What would be two reasons for this failure? (Choose two.)

Question20: Click the exhibit button.

Your customer reports that their FAS2554A system reports multi-path HA when running the sysconfig command. However, Config Advisor reports an error about incorrect cabling.
What are the two reasons for the messages? (Choose two.)

Question21: Click the exhibit button.

A customer reports that storage latency has recently increased substantially. No changes have been introduced, and the traffic did not change.
Referring to the output shown in the exhibit, which corrective step should be taken?

Question22: Click the exhibit button.

A customer reports that their system recently began logging an error.
Referring to the exhibit, which two statements are correct? (Choose two.)

Question23: What is a major difference between NFSv3 and NFSv4.x?

Question24: Click the exhibit button.

You execute a few commands and many fail, as shown in the exhibit.
What could cause the error?

Question25: A customer's FAS8200 node1 went down an hour ago after a WAFL inconsistency error. All data is being served from partner node2, but the storage failover showcommand output is not showing a node1 as "Waiting for giveback".
What is the corrective action for this situation?
