Question3: Click the Exhibit button at the right.
A customer reports that a node panicked due to a multidisk failure.
While in take over, the customer reviewed the output of the sysconfig -a command and noticed a discrepancy in the shelf stack as shown in the exhibit.

The customer proceeded to examine the power supplies in the stack of shelves; all were functional.
Which step would you take to solve this problem?

Question4: After a storage administrator turned off IP fast path, all the NFS clients lost connectivity to the storage controller.
Which statement describes what happened in this scenario?

Question5: A customer mentions that their Windows users cannot access clustered Data ONTAP 8.3.1 CIFS shares. The users see "access denied" on the Windows side.
Host name resolution is working and properly resolves IP to host name and host name to IP and the customer can ping using host name and IP. In this scenario, which statement describes the problem?

Question6: A customer is concerned because an external tool is reporting 100% CPU utilization on node "netapp-01". There are no reports of latency or throughput issues. You execute some commands and obtain the output shown in the exhibit.
Based on the output, you see no problems. In this scenario, what are two reasons that support your position? (Choose two.)

Question7: Referring to the exhibit.

A customer is attempting to protect the source volume listed in the exhibit. They try to initialize a DP mirror relationship to the destination volume but it will not initialize as expected.
Which two settings on the destination volume are causing this problem? (Choose two.)

Question8: A customer created a new storage virtual machine (SVM) named "svm-nfs". They enabled only NFSv3 and created a new export policy called "Linux". In this policy, they created a rule replacing the default rule that shows the host specifier to be IP address 172.16.100.0/24.
This configuration has worked well for the past two weeks for all Linux clients. A new Linux client is about to be put into production but it is not able to access the NFS mount. The root user on this new client is not able to mount as well. They receive the "access denied" error.
Which statement is correct in this scenario?

Question9: A client is attempting to mount a UNIX security style volume using NFSv4. The client receives the
"permission denied" message, but mounting NFSv3 works fine. You have confirmed both NFSv4 and NFSv3 are allowed in the export policy.
Which statement describes this behavior?

Question10: Which two statements are true about epsilon in a 4-node cluster? (Choose two.)

Question11: You are preparing to implement a storage virtual machine (SVM) in a SAN configuration. You need to eliminate single points of failure and enable the system to survive component failures.
According to NetApp, what is the recommended minimum number of paths per LUN connecting to each node being used by an SVM in a cluster?

Question12: A user on an NFSv4 client is listing a directory and sees the file in an is -1 listing shown below:
"rwr------1 nobody nobody 10767 Mar 24 2016 party.txt"
The customer would like to know why the user and group shows as "nobody".
Which statement would explain why this is happening?

Question13: A customer wants to upgrade a cluster to a new version of ONTAP. In this scenario, what are two ways to ensure a successful upgrade? (Choose two.)

Question14: A manager wants a volume to have a guaranteed 300 MB/s of read performance. You explain that you cannot do this on FAS storage running ONTAP 9.3 backed by 10,000 RPM disks.
What is the reason for this response?

In this scenario, what are two reasons for this problem? (Choose two.)

Question19: You have a 4-node MetroCluster configuration. The systems are operating normally with no faults.
In this scenario, which statement describes the usage of NVRAM when a host sends a write to a node?

Question20: Referring to the exhibit.

A customer contacts you and asks for assistance in determining which ports can be used for a new broadcast domain on a clustered Data ONTAP 8.3.2 system.
The system is serving LUNs using the FC protocol and is in production.
However, for Ethernet traffic, it is not yet in production. The customer provides you the output of the network port show command.
Referring to the exhibit, which ports will be eligible to create a new broadcast domain without impacting production storage virtual machines (SVMs) serving FC LUNs?

Question21: While troubleshooting intermittent takeover impossible command entries on the console, you request the output of the storage failover interconnect statistics error show command.
Which two counters would help troubleshoot this problem? (Choose two.)

Question22: Referring to the exhibit.

A customer receives "CLUSTER NETWORK DEGRADED" AutoSupport messages from this clustered Data ONTAP system. The customer suspects that something occurred physically to the nodes after they had a data center maintenance move.
The customer proceeds to follow the instructions in the Knowledge Base article regarding the "Error: CLUSTER NETWORK DEGRADED" message that results in the output shown In the exhibit.
After analysis, the customer decides to replace the small form-factor pluggable (SFP) transceivers and the cables on the system.
Which statistic supports the customer's analysis?

Question23: What is the next step if you must escalate an open case?

Question24: A 2-node cluster (Node-1 and Node-2) has suffered a takeover event. The down node (Node-1) is currently waiting for give back.
However, it is unsure if the node will boot successfully. The client suffer any data outage.
Which command would you use to perform the give back?

Question25: Which two OnCommand products would you use to manage your clustered Data ONTAP systems? (Choose two.)

In this scenario, what information should the customer collect from the Remote LAN Module (RLM) and send to you? (Choose two.)

Question27: Click the Exhibit button at the right.
When using ONTAP, the customer uses a mirror-SnapVault cascade, as shown in the exhibit. The Snapshot copies successfully transfer from the primary volume on storage system A to the SnapMirror destination on storage system B.
However, not all SnapMirror Snapshot copies are being transferred from storage system B to the XDP destination on storage system C.

In this scenario, which Snapshot copies will transfer successfully?

In this scenario, which two actions are required to solve this problem? (Choose two.)

Question32: A customer wants to protect the data in a volume using a schedule configured on a cluster. The customer is required to retain more backups on the destination than are present on the source.
What would the customer use to protect the data in this situation?

Question33: An administrator on a clustered Data ONTAP 8.3.1 system created a FlexClone of a volume containing a LUN, but the new LUN Is offline and cannot be seen by the client.
In this scenario, which two actions will solve the problem? (Choose two.)

Which process is causing the problem in this scenario?

Question36: Referring to the exhibit.

The customer configured an SVM called "NewSVM" for NFS, configured the volume, "vol_nfs", mounted at "/vol_nfs", and set up NFSv3 as shown in the exhibit.
However, if they try to mount from the client with IP address 192.168.10.10, they receive a "permission denied" error. In this scenario, which action will solve the error condition?

Question37: A Linux client is experiencing low throughput when reading a very large file using NFS. Network counters suggest there is packet drop in the network.
To confirm whether dropped packets affect the Linux client, you are collecting network traces from the affected systems.
