Question1: 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.)

Question2: A customer reports that one their SVMs has two default gateways. The customer wants to know whether this behavior is expected or if one of gateways should be deleted.
In this scenario, what do you tell the customer?

Question3: 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.)

Question4: Click the exhibit button.

Your customer has severe latency on one of their SATA aggregates. You run the statit -b and statit -e commands to obtain detailed disk statistics.
Referring to the output shown in the exhibit, which disk would be the problem?

Question5: 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.)

Question6: Click the exhibit button.

A customer has an FC SAN with brocade switches. Each server attached to the SAN gas four FC ports. The customer describes that one of their servers has only four paths to the LUNs configured on the cluster. There should be eight paths on all the other servers. The switch administrator has verified the zone configuration.
Referring to the exhibit, which two actions would you perform to troubleshoot the problem? (Choose two.)

Question7: 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.)

Question8: A customer mentions that their intercluster SnapMirror replication operations consistently take much longer than normal. While troubleshooting, you want to initiate a test SnapMirror session to collect performance data.
How would you accomplish this task?

Question9: 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.)

Question10: 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.)

Question11: An administrator wants to keep an automatic daily up-to-date copy of a volume at a disaster recovery location.
What should the administrator do to achieve this goal?

Question12: Click the exhibit button.

When you log in to a node, a warning is displayed as shown in the exhibit.
Which statement is correct in this scenario?

Question13: Click the exhibit button.

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

Question14: Click the exhibit button.

A customer has the ns-switch shown in the exhibit.
Which two statements are true in this scenario? (Choose two.)

Question15: What is a major difference between NFSv3 and NFSv4.x?

Question16: A non-maskable interrupt event occurs. The system panics and then reboots.
In this scenario, what would have caused the panic?

Question17: A customer complains that the copy offload does not work when copying large file from a Windows 8 client between the CIFS shares that are hosted on the same ONTAP cluster.
What are two reasons for this problem? (Choose two.)

Question18: You migrated from a FAS3250 system to a new A200 system. After the migration, you notice that data compaction fails to be enabled on the migrated volumes.
In this scenario, which statement is correct?

Question19: 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.)

Question20: A customer reports that a takeover has been disabled on an HA pair.
What would be a cause for this to happen?

Question21: In a 4-node cluster, nodes 1 and 2 are an HA pair, and nodes 3 and 4 are an HA pair. The following error appears in the log.
12/15/2018 15:48:47 node-2CRITICALclam.node.ooq: Node (name=node- 2, ID= 1001) is out of "CLAM quorum" (reason =quorum update).
In this scenario, which two statements are correct? (Choose two.)
