Question 1

You recently discovered the error message shown below in your ONTAP logs. https://kxbjsyuhceggsyvxdkof.supabase.co/storage/v1/object/public/file-images/NetApp_NS0-593/page_14_img_1.jpg What should be your first action to correct this Issue?

Accepted Answer

B

Explanation: = 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 = 1 Volume Showing WAFL Inconsistent - NetApp Knowledge Base

Question 2

You created a new NetApp ONTAP FlexGroup volume spanning six nodes and 12 aggregates with a
total size of 4 TB. You added millions of files to the FlexGroup volume with a flat directory structure
totaling 2 TB, and you receive an out of apace error message on your host.
What would cause this error?

Accepted Answer

D

Explanation: The maxdirsize is the maximum size of a directory in a FlexVol or FlexGroup volume. It is determined by the number of inodes allocated to the directory. If the directory contains more files than the maxdirsize can accommodate, then the ONTAP software will return an out of space error message to the host, even if the volume has enough free space. This can happen when a FlexGroup volume has a flat directory structure with millions of files, as the maxdirsize is not automatically adjusted for FlexGroup volumes12. Reference: 1: FlexGroup volumes: Frequently asked questions | NetApp Documentation 2: How to increase the maxdirsize of a FlexVol volume - NetApp Knowledge Base

Question 3

Which two statements about NetApp Cloud Volumes ONTAP licenses ate true? (Choose two.)

Accepted Answer

A, C

Explanation: Having an Essentials package enables you to convert to another licensing option. This is true because the Essentials package is a capacity-based licensing option that allows you to pay for Cloud Volumes ONTAP per TiB of capacity. You can switch to another capacity-based package or to a Keystone Flex Subscription at any time1. BYOL licenses are purchased directly from NetApp. This is true because BYOL stands for Bring Your Own License, which means you need to obtain a license from NetApp before deploying Cloud Volumes ONTAP systems in any cloud provider2. Capacity-based license packages support only single-node configurations. This is false because capacity-based license packages support both single-node and HA configurations1. AWS Marketplace contracts cannot be mixed with BYOL. This is false because you can mix AWS Marketplace contracts with BYOL as long as the license type matches the instance type3.

Question 4

Your customer added a new DS4246 shelf to their FAS2750 single-node system and created a new
aggregate on the new shelf. Two weeks later, they log into Active IQ and discover the Medium
Impact error shown below.
Shelves with both connections via the same SAS path detected
NS0-593 practice exam questions

Referring to the exhibit, which statement is correct?

Accepted Answer

B

Explanation: According to the SAS cabling rules and concepts for shelves with IOM12/IOM12B modules1, one of the goals is to provide a single, easily understood universal algorithm for all SAS products and configurations. One of the rules is that of the two paths to a single disk storage stack from a single node, one should connect to the top and one to the bottom of the storage stack. This ensures maximum possible resilience and minimizes the reliance on controller takeovers. The exhibit shows that both SAS connections from one controller go to the same shelf, which violates this rule and causes the error message. This situation is not normal for a FAS2750 single-node system and can reduce reliability and availability. The cables should be reconnected according to the SAS cabling rules and the controller-to-stack cabling worksheet template for quad-pathed connectivity2. Reference = SAS cabling rules and concepts - shelves with IOM12/IOM12B modules, SAS cabling issue: Both SAS connections from one controller go to the same shelf, Controller-to-stack cabling worksheet template for quad-pathed connectivity.

Question 5

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. https://kxbjsyuhceggsyvxdkof.supabase.co/storage/v1/object/public/file-images/NetApp_NS0-593/page_38_img_1.jpg Referring to the exhibit, on which interface do you have to run the packet trace?

Accepted Answer

B

Explanation: 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.

Question 6

Your customer complains that u host will constantly report losing a connection to the iSCSl target and then report that the session was reestablished. https://kxbjsyuhceggsyvxdkof.supabase.co/storage/v1/object/public/file-images/NetApp_NS0-593/page_7_img_1.jpg As shown in the exhibit, what is a cause of this flapping?

Accepted Answer

A

Explanation: IQN stands for iSCSI Qualified Name, which is a unique identifier for an iSCSI initiator or target1. ONTAP uses IQN to authenticate and authorize iSCSI sessions2. If two hosts have the same IQN, they will cause a conflict and ONTAP will reject the new session request from the second host3. This will result in the host losing the connection to the iSCSI target and then reporting that the session was reestablished, as shown in the exhibit. To avoid this problem, each host should have a unique IQN.

Question 7

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:
NS0-593 practice exam questions

The same credentials work in another application.
In this scenario, what would cause this problem?

Accepted Answer

B

Explanation: 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 Reference = 1 ONTAP S3 Server Overview - NetApp Documentation 2 Accessing an ONTAP S3 bucket - NetApp Documentation

Question 8

You have a NetApp ONTAP cluster consisting of four NetApp FAS8200 controllers with two NetApp
CN1610 cluster switches running ONIAP 9.8 software. You are receiving several alert messages
stating that the cluster network has degraded. After troubleshooting, you determine that the errors
are being generated from Node 2, interface e0b.
In this scenario, what should you do first to solve this problem?

Accepted Answer

A

Explanation: A Twinax cable is a type of copper cable that is used to connect cluster ports to cluster switches1. A cluster port is a network port that is configured for cluster communication and data access2. A cluster switch is a network switch that is used to interconnect the nodes in a cluster and provide redundancy and load balancing3. A cluster network is a network that enables cluster communication and data access between the nodes in a cluster and external clients4. A cluster network can be degraded due to various reasons, such as misconfiguration, malfunction, or excessive link errors on the cluster ports or the cluster switches. Link errors are errors that occur on the physical layer of the network, such as CRC errors, length errors, alignment errors, or dropped packets. Link errors can indicate a problem with the cable, the switch port, the network interface card (NIC), or the cable connector. In this scenario, the alert messages state that the cluster network has degraded and the errors are being generated from Node 2, interface e0b. The first step to solve this problem is to replace the Twinax cable between Node 2, interface e0b and the NetApp CN1610 switch, as this could be the source of the link errors. Replacing the cable could resolve the issue and restore the cluster network to a healthy state. If replacing the cable does not solve the problem, then other steps may be required, such as checking the switch port, the NIC, or the cable connector, or replacing the switch or the motherboard.

Question 9

You have recently discovered that NetApp ONTAP Cloud Manager is not sending AutoSupport messages to NetApp. In this scenario, what would solve this Issue?

Accepted Answer

B

Explanation: = 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 10

You have a customer who is concerned with high CPU and disk utilization on their SnapMirror
destination system. They are worried about high CPU and disk usage without any user operations.
In this situation, what should you tell the customer?

Accepted Answer

B

Explanation: SnapMirror is a data replication technology that allows efficient and flexible data protection and disaster recovery for NetApp ONTAP storage systems1 SnapMirror transfers data between source and destination volumes using a network connection. SnapMirror can use storage efficiency features such as compression and deduplication to reduce the amount of data transferred and stored1 SnapMirror transfers are scheduled and controlled by policies that define the frequency, retention, and priority of the transfers. SnapMirror policies can also specify the network bandwidth limit for the transfers2 SnapMirror transfers are considered background tasks that run in the absence of user workload. SnapMirror transfers can consume CPU and disk resources on both source and destination systems, depending on the amount and type of data being replicated3 SnapMirror transfers can throttle up or down depending on the availability of system resources and network bandwidth. SnapMirror transfers will throttle up when there is no user workload, and throttle down when there is user workload. This is to ensure that SnapMirror transfers do not impact the performance of user operations3 Therefore, if a customer is concerned with high CPU and disk utilization on their SnapMirror destination system, the best answer is to explain that background tasks such as SnapMirror throttle up in the absence of user workload. This is normal and expected behavior, and it does not indicate a problem with the system3 Reference: 1: ONTAP 9 Data Protection - SnapMirror - The Open Group 2: ONTAP 9 Data Protection - SnapMirror Policies - The Open Group 3: SnapMirror storage efficiency configurations and behavior - Resolution Guide - NetApp Knowledge Base

Question 11

You notice poor performance on your FlexGroup and execute the system node run -node * flexgroup
show command for more Information. You notice the "Urge" column has non-zero values.
In this scenario, which statement is true?

Accepted Answer

C

Explanation: = The “Urge” column in the flexgroup show command indicates the urgency of data rebalancing for each constituent volume. A non-zero value means that the data placement is uneven across the volumes, which can affect the performance of the FlexGroup. The target value is the desired percentage of data for each volume, and the difference value is the deviation from the target. The FlexGroup tries to balance the data placement by moving data between the volumes, but this process can be slow or interrupted by other factors. Therefore, it is recommended to monitor the “Urge” column and take corrective actions if the values are high or persistent.

Question 12

You receive the panic message shown in the exhibit. https://kxbjsyuhceggsyvxdkof.supabase.co/storage/v1/object/public/file-images/NetApp_NS0-593/page_34_img_1.jpg In this scenario, which component should you troubleshoot first?

Accepted Answer

A

Explanation: = 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 the system node hardware pci show command to check the status of the PCI card and the system node hardware firmware update command 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 message 2: [system node hardware pci show] 3: [Panic Message Analyzer tool]

Question 13

Refer to the exhibit. https://kxbjsyuhceggsyvxdkof.supabase.co/storage/v1/object/public/file-images/NetApp_NS0-593/page_18_img_1.jpg Referring to the exhibit, what do you need to do to return the MetroCluster to a normal state?

Accepted Answer

B

Explanation: The question refers to a MetroCluster configuration, which is a disaster recovery solution that uses two physically separated, mirrored clusters1. The exhibit shows a MetroCluster switchover scenario, where Site A has experienced a disaster and Site B has taken over the tasks of Site A2. To return the MetroCluster to a normal state, you need to perform a MetroCluster switchback operation, which reverses the switchover and activates the original sync-source storage virtual machines (SVMs) on Site A3. To perform a MetroCluster switchback, you need to enter the metrocluster switchback command on the cluster that was the source of the switchover, which is Site A in this case3. The other options are not correct, because: A) Entering the metrocluster switchback command on Site B will not work, as Site B is the destination of the switchover, not the source3. C) Entering the storage failover giveback command on Site B will not work, as this command is used for local HA failover within a cluster, not for MetroCluster switchover between clusters4. D) Entering the storage failover giveback command on Site A will not work, as this command is used for local HA failover within a cluster, not for MetroCluster switchover between clusters4.

Question 14

Your customer Informs you about SnapMlrror problems after upgrading NetApp ONTAP software to a
newer version. After investigating the event logs and the SnapMirror history, you see information
about delayed updates of the SnapMirror relationships.
How would your customer prevent such problems in the future?

Accepted Answer

A

Explanation: Quiescing the SnapMirror relationships before upgrading the ONTAP software ensures that the data replication is completed and consistent across the source and destination volumes. This prevents any data loss or corruption due to the upgrade process. Quiescing also suspends the scheduled updates until the relationships are resumed, avoiding any delays or failures in the transfers. The other options are not effective in preventing the SnapMirror problems after the upgrade.
