Question 1

A user reports that a colleague saved a file called Test.txt from a UNIX system to a multiprotocol volume. When opening the file later from a Windows system, it was not the file that they wanted. The file that they wanted was named TEST~1.TXT.

Which statement explains this behavior?



Answer : D

= The multiprotocol volume allows clients to access files using both NFS and SMB protocols. The NFS protocol is case-sensitive, meaning that Test.txt and TEST~1.TXT are two different files. The SMB protocol is case-insensitive, meaning that it treats uppercase and lowercase letters as the same when searching for a file. Therefore, when the user opened the file from a Windows system using SMB, the system could not distinguish between Test.txt and TEST~1.TXT and displayed one of them arbitrarily. This could lead to confusion and data loss if the user modified or deleted the wrong file.Reference=Client protocols;Multiprotocol NAS in NetApp ONTAP Overview and Best Practices, page 30-31.


Question 2

You have a 2-node NetApp FAS2750 switchless cluster with twenty-four 1.8 TB disks that is experiencing performance issues. Upon investigation, you discover several type B consistency points.

Referring to the exhibit, which corrective action would address these consistency points?



Answer : C

A type B consistency point (CP) is triggered when the NVRAM buffer is full and needs to be flushed to disk.A type B CP indicates that the write workload is higher than the disk throughput, and the system is experiencing back pressure1

A switchless cluster is a cluster configuration that does not use external switches for cluster interconnect and management network.A switchless cluster has lower bandwidth and redundancy than a switched cluster, and is limited to two nodes2

The exhibit shows the output of the sysstat -x command, which displays the system performance statistics in extended mode. The output shows that the system has high CPU utilization, high disk utilization, high NVRAM utilization, and several type B CPs.These are signs of performance issues and resource contention3

The best corrective action to address these consistency points is to add an additional shelf of twenty-four 1.8 TB disks.This will increase the disk capacity and throughput, and reduce the disk utilization and the frequency of type B CPs4

Creating additional data LIFs will not address the consistency points, because the data LIFs are used for data access protocols, not for NVRAM flushing5

Converting the 2-node switchless cluster to a 2-node switched cluster will not address the consistency points, because the cluster interconnect and management network are not related to the disk performance6

Replacing the twenty-four 1.8 TB disks with twelve 4 TB disks will not address the consistency points, because the disk throughput will not increase, and the disk utilization will remain high7

Question 3

You Just used the CLI to create a NetApp ONTAP FlexGroup Volume on a NetApp Cloud Volumes ONTAP instance. After creation, you notice odd behavior in NetApp Cloud Manager.

In this scenario, what Is the reason for this behavior?



Answer : B

= According to the NetApp Knowledge Base1, while Cloud Volumes ONTAP supports FlexGroup volumes, Cloud Manager does not. If you create a FlexGroup volume from System Manager or from the CLI, then you should set Cloud Manager's Capacity Management mode to Manual. Automatic mode might not work properly with FlexGroup volumes.The other options are incorrect because Cloud Volumes ONTAP does support FlexGroup volumes2, the Capacity Management Mode should not be set to Automatic, and Cloud Manager is not required to provision the FlexGroup volume3.Reference=1,2,3


Question 4

Your customer calls you because one application is not able to access a NetApp ONTAP S3 bucket. While reviewing the EMS log on the cluster, you see the following message:

The same credentials work in another application.

In this scenario, what would cause this problem?



Answer : B

The error message indicates that the access is denied for user 'anonymous user' (Vserver 50), from client IP 10.10.10.10 accessing resource '/offload-target'. This means that the application is not providing a valid user name or access key to authenticate with the ONTAP S3 server.According to the NetApp documentation1, ONTAP S3 server supports both v2 and v4 signatures, but v2 signatures are deprecated and not recommended. Therefore, the application should use v4 signatures to access the ONTAP S3 bucket.Additionally, the application should specify the bucket name in the host name, not in the resource path, as shown in the following example2:

https://bucket-name.s3-server-name.com/object-name

Question 5

You have recently discovered that NetApp ONTAP Cloud Manager is not sending AutoSupport messages to NetApp.

In this scenario, what would solve this Issue?



Answer : B

= AutoSupport is enabled by default for Cloud Manager and ONTAP Cloud systems. It proactively monitors the health of your systems and sends messages to NetApp technical support. To enable AutoSupport, you must provide your NetApp Support site credentials to Cloud Manager. If your credentials are incorrect or expired, Cloud Manager will not be able to send AutoSupport messages to NetApp. Therefore, the solution for this issue is to verify that your NetApp Support site credentials are correctly added to Cloud Manager.Reference=Troubleshooting Cloud Manager and ONTAP Cloud,Set up AutoSupport


Question 6

The motherboard of Node-01 is being replaced. To perform this task, a takeover was Initiated from Node-02. Node-02 panics showing the string below.

PANIC; Permanent errors on all HA mailbox disks (while marshalling header) in SKprocess fnmbx_instanceWorker on release 9.5P8 (C)

What has happened in this situation?



Answer : D

The mailbox disks are the first two disks of the root aggregate on each node of an HA pair. They store the HA state information and the panic dump files.The mailbox disks are used for communication between the HA partners and for takeover and giveback operations1

The mailbox destroy local command is used to destroy the mailbox disks on the local node. This command is only available in maintenance mode and should be used with extreme caution.The command is intended for situations where the mailbox disks are corrupted or inaccessible and need to be recreated2

If the mailbox destroy local command is executed on a node that is in takeover mode, the node will panic with the message ''Permanent errors on all HA mailbox disks''.This is because the node will lose the HA state information and the panic dump files of the partner node, and will not be able to communicate with the partner node or perform a giveback operation3

Therefore, if the motherboard of Node-01 is being replaced, and a takeover was initiated from Node-02, and Node-02 panics showing the string ''Permanent errors on all HA mailbox disks'', the most likely cause is that the mailbox destroy local command was executed on Node-02 while in maintenance mode.This is a serious error that can result in data loss and system downtime4

Question 7

When an administrator tries to create a share for an existing volume named voll, the process fails with an error.

Referring to the exhibit, what Is the reason for the error?



Answer : B

The error message indicates that the specified path ''/vol1'' does not exist in the namespace belonging to Vserver ''svm1''. This means that the volume ''vol1'' has not been mounted to the Vserver's namespace, which is required for creating a share. The volume type, the CIFS service status, and the CIFS service mode are not relevant to the error.Reference=https://www.netapp.com/support-and-training/netapp-learning-services/certifications/support-engineer/
