Question 1

Your customer wants to access a LUN on a FAS 8300 system from a VMware ESXi server through the FC protocol. They already created a new SVM, volume. LUN, and igroup for this purpose. The customer reports that the server's FC HBA port Is online, but the LUN does not show up.

Referring to the exhibit, what is the reason for this problem?



Answer : A

To access a LUN on a FAS 8300 system from a VMware ESXi server through the FC protocol, the customer must configure the FC service on the SVM that owns the LUN. The FC service enables the SVM to act as an FC target and communicate with the FC initiators on the host. Without the FC service, the LUN will not be visible to the host, even if the LUN is mapped to an igroup and the FC LIFs are up. The exhibit shows that the FC service is not configured on the SVM, as the output of the commandvserver fcp initiator show -vserver SVM1is empty. Therefore, the reason for the problem is that the FC service has not been configured on the SVM.Reference=Configure an SVM for FC,Create an FC protocol service,Single IQN iSCSI session with ESXi on ONTAP when igroup has two IQNs


Question 2

You have a 4-node NetApp ONTAP 9.8 cluster with an AFF A400 HA pair and a FAS8300 HA pair with 16 TB NL-SAS drives. You are asked to automatically tier 150 TB of Snapshot copy data from the AFF A400 aggregates to the FAS8300.

In this scenario, which ONTAP license must be added to the cluster to accomplish this task?



Answer : D

FabricPool is an ONTAP feature that enables tiering of cold data from SSD aggregates to low-cost object storage, either on-premises or in the cloud1.FabricPool requires a license to be installed on the cluster, and the license type depends on the cloud tier being used2.In this scenario, the cloud tier is another ONTAP cluster (FAS8300), which is not supported by the new Cloud Tiering license that is used for most FabricPool configurations3.Therefore, the old FabricPool license that is retained for dark sites or MetroCluster systems using FabricPool Mirror must be used3.The FabricPool license defines the amount of capacity that can be tiered to the cloud tier, and it can be increased by add-on orders4.Reference:

Question 3

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



Answer : A, C

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.Reference:1: Cloud Volumes ONTAP licensing | NetApp Documentation2: Set up licensing for Cloud Volumes ONTAP in Google Cloud - NetApp3: Set up licensing for Cloud Volumes ONTAP in AWS - NetApp


Question 4

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 5

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 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.

As shown in the exhibit, what is a cause of this flapping?



Answer : A

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.Reference:

Question 7

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?



Answer : D

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 Documentation2: How to increase the maxdirsize of a FlexVol volume - NetApp Knowledge Base
