Question 1

Your customer complains about missing volume snapshot copies on a SnapMlrror destination. While investigating this case, you notice an executed SnapMirror resync operation in the event logs of the system.

In this scenario, what Is the cause of this problem?



Answer : A

= When a SnapMirror resync operation is performed, the destination volume is reverted to the most recent common snapshot copy with the source volume. Any newer snapshot copies that exist on the destination volume are deleted automatically, unless they are marked as busy or locked. This is done to ensure that the destination volume is consistent with the source volume and to avoid data loss or corruption. Therefore, if the customer complains about missing snapshot copies on the destination volume after a SnapMirror resync, the most likely cause is that those snapshot copies were newer than the common snapshot that was chosen for resync and were removed automatically by the system.Reference=SnapMirror resync operation,SnapMirror resync or update failed No Snapshot copies found on volume,Even though there is common snapshot, SnapMirror resync fails with error: No common snapshot copy found between source and destination volume


Question 2

A customer calls you to troubleshoot a network issue. The customer wants to create a packet trace for all clients on the 192.168.9.0/24 subnet.

Referring to the exhibit, on which interface do you have to run the packet trace?



Answer : B

To create a packet trace for all clients on the 192.168.9.0/24 subnet, you have to run the packet trace on the interface that has an IP address in the same subnet. According to the exhibit, the only interface that matches this criterion is e2a-100, which has an IP address of 192.168.3.1/24. The other interfaces have IP addresses in different subnets, such as 10.92.4.202/16, 10.91.3.132/24, 10.95.7.114/24, and 10.92.6.200/16. Therefore, the correct answer is B. e2a-100.Reference=How to capture packet traces on ONTAP 9.10+ systems,How to capture packet traces (tcpdump) on ONTAP 9.2 to 9.9 systems,How to download captured packet traces from ONTAP


Question 3

You receive the panic message shown in the exhibit.

In this scenario, which component should you troubleshoot first?



Answer : A

= The panic message indicates that the node encountered a fatal error while accessing the PCI card in slot 31. This could be due to a hardware failure, a firmware issue, or a driver problem. The first component to troubleshoot is the PCI card in slot 3, as it is the most likely source of the error.You can use thesystem node hardware pci showcommand to check the status of the PCI card and thesystem node hardware firmware updatecommand to update the firmware if needed2.You can also use the Panic Message Analyzer tool from the NetApp Support Site to determine whether your panic was caused by a known software issue3.Reference=1:REBOOT (panic) ALERT - AutoSupport message2: [system node hardware pci show]3: [Panic Message Analyzer tool]


Question 4

You are troubleshooting a CIFS connection issue that is reported by some users. You decide to collect a packet trace.

In this scenario, after you generate the packet trace, where do you find the trace file?



Answer : B

According to the NetApp Knowledge Base, packet traces are stored in the /etc/log/packet_traces directory of the node hosting the LIF. This applies to ONTAP 9.10 and above systems. For ONTAP 9.2 to 9.9 systems, the procedure to capture packet traces is similar, but the command syntax is slightly different. For ONTAP pre-9.2 systems, the procedure is different and requires the use of the tcpdump command.Reference=How to capture packet traces on ONTAP 9.10+ systems,How to capture packet traces (tcpdump) on ONTAP 9.2 to 9.9 systems,How to capture packet traces in ONTAP pre-9.2


Question 5

You receive the "Unable to connect to the management gateway server" error when trying to connect to a node management IP.

In this situation, how do you determine whether core dumps are generated for the mgwd user space process?



Answer : D

The mgwd user space process is responsible for managing the cluster configuration and providing the management interface for ONTAP. If this process crashes, it may generate a core dump file in the /mroot/etc/mgwd/core directory of the node. To access this directory, you need to log in to the systemshell, which is a Linux shell that runs on the node. The systemshell can be accessed by logging in to the nodeshell using the node console and then running the systemshell command. The nodeshell is a custom shell that provides access to ONTAP commands and utilities. The service processor and the clustershell are not relevant for collecting core dumps from the mgwd process.Reference=ONTAP 9 Cluster Administration, page 29-30;ONTAP 9 Troubleshooting Guide, page 23-24.


Question 6

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/

Question 7

You recently discovered the error message shown below in your ONTAP logs.

What should be your first action to correct this Issue?



Answer : B

= The error message indicates that the volume my_data_vol is WAFL inconsistent, which means that there is a discrepancy between the data blocks and the metadata in the file system. This can be caused by various factors, such as hardware failures, software bugs, power outages, or network disruptions.The first action to correct this issue is to determine the root cause behind the inconsistency before attempting any recovery procedure, as recommended by the NetApp documentation1. This is because some recovery procedures, such as wafliron or storage takeover, may not work or may cause further damage if the underlying cause is not resolved. For example, if the inconsistency is due to a faulty disk or shelf, running wafliron may not fix the problem and may even corrupt more data.Therefore, it is important to identify and isolate the cause of the inconsistency before taking any further steps.Reference=1Volume Showing WAFL Inconsistent - NetApp Knowledge Base
