NEW QUESTION # 36
Your customer installed the shelf firmware for their NS224 shelf over a week ago, and the firmware has not upgraded on shelf 1 module B. The customer wants to know what the next steps would be to get the firmware upgraded after verifying that the shelf firmware is indeed loaded onto the system.
Which step would you perform to complete the firmware upgrade?
- A. Reseat the PSU of the shelf.
- B. Reseat the disk in Bay 0.
- C. Reseat the NSM100 module.
- D. Power cycle the shelf.
Answer: C
Explanation:
The question refers to a scenario where the shelf firmware for an NS224 shelf has not been upgraded on one of the NVMe shelf modules (NSM) after a week of installation.
The NSM is responsible for managing the communication between the drives and the I/O modules (IOM) in the shelf1.
The shelf firmware for the NSM is automatically updated when the NSM is inserted into the shelf or when the system is rebooted2.
If the automatic update does not work, the manual update process involves reseating the NSM, which means removing it from the shelf and inserting it back3.
Reseating the NSM triggers the firmware update and also resets the NSM's state3.
The other options are not correct, because:
B) Reseating the disk in Bay 0 will not affect the NSM firmware update, as the disk is not connected to the NSM1.
C) Power cycling the shelf will disrupt the I/O operations and may cause data loss or corruption4.
D) Reseating the PSU of the shelf will not affect the NSM firmware update, as the PSU is not connected to the NSM1. Reference:

NEW QUESTION # 38
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?
- A. The data placement is uneven.
- B. The aggregate is completely full.
- C. The constituent volumes are out of Inodes.
- D. The constituent volumes are completely full.
Answer: A
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.

NEW QUESTION # 39
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?
- A. FabricPool license
- B. S3 license
- C. VE license
- D. TPM license
Answer: A
Explanation:
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:

NEW QUESTION # 41
A storage administrator reports that a monitoring toot is reporting that the storage controller reads between 90% to 93% CPU use. You run the sysstat -m command against the node in question.
Referring to the exhibit, which statement is correct?
- A. You should immediately investigate further by gathering perfstat data and opening a support case.
- B. The CPU Is not a first-order monitoring metric for ONTAP.
- C. The customer should be advised to exclude certain workflows to reduce use.
- D. High network exempt use could be a problem.
Answer: B
Explanation:
= CPU utilization in ONTAP is not a linear measure of the system load, nor can it be used alone as a measure of the overall system utilization. ONTAP uses a Coarse Symmetric Multiprocessing (CSMP) design which partitions system functions into logical processing domains, each with its own scheduling rules and resource availability. Therefore, a high CPU utilization does not necessarily indicate a performance problem, unless it is accompanied by other contributing factors such as high latency, low throughput, or high queue depth. ONTAP has several mechanisms to optimize CPU usage and balance the workload across the cores, such as WAFL parallelization, exempt processing, and CPU pinning. The CPU utilization reported by the sysstat command is an average across all cores and domains, and does not reflect the actual CPU activity or availability for each domain. Therefore, the CPU is not a first-order monitoring metric for ONTAP, and other metrics such as latency, throughput, and queue depth should be considered first.

NEW QUESTION # 48
Your customer mentions that they have accidentally destroyed both root aggregates in their two-node cluster.
In this scenario, what are two actions that must be performed? (Choose two.)
- A. Re-create the cluster from the local backup.
- B. Install ONTAP from a USB device.
- C. Re-create the cluster from the remote backup.
- D. Rejoin the second node to the re-created cluster.
Answer: B,D
Explanation:
If both root aggregates are destroyed in a two-node cluster, the cluster will be inoperable and the data will be inaccessible. To recover from this situation, you need to perform the following actions:
Install ONTAP from a USB device on one of the nodes. This will create a new root aggregate and a new cluster on that node.
Rejoin the second node to the re-created cluster. This will also create a new root aggregate on the second node and synchronize it with the first node.
Restore the cluster configuration and data from a backup, if available. Reference = ONTAP 9 Documentation Center Storage System Recovery Troubleshooting Recovering from a root aggregate failure
NEW QUESTION # 49
You recently discovered the error message shown below in your ONTAP logs.
What should be your first action to correct this Issue?
- A. Use the wafliron command against my_data_vol to solve the inconsistency on the volume.
- B. Determine the root cause behind the inconsistency before attempting any recovery procedure.
- C. Power cycle all the disk storage shelves that contain drives of the aggregate with the my_data_vol volume.
- D. Use the storage takeover command on the storage controller that contains my_data_vol.
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
NEW QUESTION # 50
You are attempting to connect a NetApp ONTAP cluster to a very complex network that requires LIFs to fail over across subnets.
How would you accomplish this task?
- A. Configure VIP LIFs using OSPF.
- B. Configure VIP LIFs using BGP.
- C. Configure an equal number of UFs on each subnet.
- D. Configure a I IF failover policy for each subnet inside a single broadcast domain.
Answer: B
Explanation:
A LIF (Logical Interface) is a logical entity that represents a network connection point on a node1.
A VIP LIF (Virtual IP LIF) is a LIF that can fail over across subnets within an IPspace2.
BGP (Border Gateway Protocol) is a routing protocol that enables VIP LIFs to advertise their IP addresses to external routers and to update the routing tables when a failover occurs3.
To connect a NetApp ONTAP cluster to a complex network that requires LIFs to fail over across subnets, you need to configure VIP LIFs using BGP on the cluster and on the external routers3.
This way, you can ensure that the network traffic is routed to the optimal node and port for each VIP LIF, and that the network connectivity is maintained in the event of a node or port failure3. Reference:

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?
- A. The FC service has not been configured on the SVM.
- B. The zoning on the FC switches Is Incorrect.
- C. The esxserver igroup contains incorrect IQNs.
- D. The LUN Is not mapped to the correct SCSI ID.
Answer: A
Explanation:
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 command vserver fcp initiator show -vserver SVM1 is 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
