質問 # 25
An administrator receives the following error message:
What are two causes for this error? (Choose two.)
- A. There is excessive SATA HDD load.
- B. There Is excessive SSD load causing the wear leveling to become unbalanced.
- C. An SSD disk is performing garbage collection to create a dense data layout.
- D. A disk is falling.
正解：B、C
解説：
The error message "wafl.cp.toolong:error" indicates that a WAFL consistency point (CP) took longer than 30 seconds to complete. A CP is a process that flushes the data from the NVRAM buffer to the disk. A long CP can cause latency and performance issues for the system1 One possible cause for a long CP is excessive SSD load causing the wear leveling to become unbalanced. Wear leveling is a technique that distributes the write operations evenly across the SSD cells to extend the lifespan of the SSD. If some SSD cells are written more frequently than others, the wear leveling will become unbalanced and the SSD performance will degrade2 Another possible cause for a long CP is an SSD disk performing garbage collection to create a dense data layout. Garbage collection is a process that reclaims the space occupied by invalid or deleted data on the SSD. Garbage collection can improve the write performance and storage efficiency of the SSD, but it can also consume CPU and disk resources and cause long CPs3 A disk failing or being failed is not a likely cause for a long CP, because the system will automatically mark the disk as failed and remove it from the aggregate. The system will also initiate a disk reconstruction or a RAID scrub to restore the data protection and redundancy4 There is no evidence that the system has SATA HDDs, so there is no reason to assume that there is excessive SATA HDD load. Moreover, SATA HDDs are usually used for secondary or backup storage, not for primary or performance-sensitive workloads5 Reference:

質問 # 27
A system panic due to an "L2 watchdog timeout hard reset" error occurred. You have found a FIFO message in the SP log.
Which FIFO message Is useful for Investigating this Issue?
- A. before NMI BBSP:C=00 L=00 FIFO: F3 F2 F1 F0 5 B2 0 0 0 80 20 E F E3 C0 C2 3 4 6 7 9 9 A
- B. before Reset BBSP:C=00 L=00 FIFO:
- C. BIOS exit BBSP:C=2F L=20 FIFO: 2 C8 C9 C4 24 4 6 18 7 8 11
- D. ONTAP Shutdown BBSP:C=00 L=2F FIFO:
正解：A
解説：
= The FIFO message before NMI is useful for investigating the issue because it shows the state of the system before the non-maskable interrupt (NMI) was triggered by the L2 watchdog timeout. The FIFO message contains information about the CPU registers, the stack pointer, the instruction pointer, and the last executed instructions. This can help identify the cause of the system hang or deadlock that led to the watchdog reset. The other FIFO messages are not useful because they show the state of the system after the reset or shutdown, which may not reflect the original problem.

You have recently discovered that NetApp ONTAP Cloud Manager is not sending AutoSupport messages to NetApp.
In this scenario, what would solve this Issue?
- A. Verify that your NetApp Support site credentials are correctly added to Cloud Manager.
- B. Verify that your AWS credentials are correctly added to Cloud Manager.
- C. Verify that the inbound and outbound rules allow AutoSupport on port 80.
- D. Verify that your data LIFs allow traffic to mysupport .netapp.com on port 443.
正解：A
解説：
= 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

質問 # 32
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?
- A. A host with an IP address of 172.20.10.80 and a second IP address of 10.10.20.60 is accessing different LUNs.
- B. A host with an IP address of 172.20.10.80 and a second host with an IP address of 10.10.20.60 are accessing the same LUN.
- C. A host with an IP address of 172.20.10.80 and a second host with an IP address of 10.10.20.60 are in different initiator groups.
- D. A host with an IP address of 172.20.10.80 and a second host with an IP address of 10.10.20.60 have the same IQN.
正解：D
解説：
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:
iSCSI Qualified Name (IQN) - NetApp
iSCSI authentication and authorization - NetApp

質問 # 33
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?
- A. Cloud Volumes ONTAP does not support FlexGroup volumes.
- B. The Capacity Management Mode within Cloud Manager should be set to Automatic.
- C. The Capacity Management Mode within Cloud Manager should be set to Manual.
- D. Cloud Manager must be used to provision the FlexGroup volume.
正解：C
解説：
= 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
質問 # 34
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?
- A. The CIFS service is not authenticating properly with the domain controller.
- B. The volume has not been mounted.
- C. The CIFS service is not in workgroup mode.
- D. The volume must have a type of DP.
正解：B
解説：
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.

質問 # 36
Refer to the exhibit.
Referring to the exhibit, what do you need to do to return the MetroCluster to a normal state?
- A. Enter the metrocluster switchback command on Site A.
- B. Enter the storage failover giveback command on Site A.
- C. Enter the metroclustor switchback command on Site B.
- D. Enter the storage failover giveback command on Site B.
正解：A
解説：
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. Reference:

質問 # 37
A 2-node cluster hosts only NAS data UFs. All nodes lose access to the cluster network.
Referring to the exhibit, which statement is correct?
- A. All nodes in the cluster reset and NAS data UFs are not accessible after reboot.
- B. Both nodes race to takeover the other, one node will takeover the other node.
- C. NAS data UFs are accessible on only the node that has Epsilon.
- D. No takeover event will occur and NAS data UFs will not be accessible.
正解：C
解説：
The two throughput elements that are controlled by host applications are operation size and concurrency. Operation size refers to the amount of data that is transferred in a single I/O request, and concurrency refers to the number of I/O requests that are issued simultaneously. Both of these factors affect the throughput of a host application, as they determine how much data can be sent or received within a given time period. Larger operation sizes and higher concurrency can increase the throughput, but they may also increase the latency and resource consumption12.

質問 # 38
After expanding a two-node AFF A300 cluster with two AFF A700 nodes, you observe latencies when data is accessed indirectly. The system node run -node -command netstat command shows retransmits and packet drops on the LIFs. The AFF A700 nodes with 40 Gbps and the AFF A300 connect with 10 Gbps to the cluster interconnect. You are using Cisco Nexus 3132Q cluster interconnect switches. You just updated to ONTAP 9.8 software.
In this scenario, what is causing this problem?
- A. The AFF A300 Is using an adapter card for the cluster Interconnect, but only onboard ports are supported.
- B. AFF A300 and AFF A700 node mixing Is not supported in ONTAP 9.8 software.
- C. There is an NXOS firmware mismatch, verify in the Interoperability Matrix (1MTJ for a supported version.
- D. The 10 Gbps to 10 Gbps cluster Interconnect is creating a speed mismatch.
正解：D
解説：
A speed mismatch occurs when the cluster ports on different nodes have different speeds, such as 10 Gbps and 40 Gbps1.
A speed mismatch can cause packet loss, retransmits, and latency on the cluster network, especially when data is accessed indirectly, meaning that the node serving the data is different from the node hosting the LIF2.
In this scenario, the AFF A300 nodes have 10 Gbps cluster ports, while the AFF A700 nodes have 40 Gbps cluster ports, creating a speed mismatch on the cluster interconnect34.
The Cisco Nexus 3132Q cluster interconnect switches support both 10 Gbps and 40 Gbps cluster ports, but they have a shallow buffer size of 9 MB per port, which can be easily overwhelmed by the bursty traffic generated by the speed mismatch.
To solve this problem, you need to either upgrade the cluster ports on the AFF A300 nodes to 40 Gbps, or downgrade the cluster ports on the AFF A700 nodes to 10 Gbps, to achieve a homogeneous cluster interconnect1.
Alternatively, you can use QoS policies to limit the bandwidth of the cluster ports to avoid oversubscription and congestion on the cluster interconnect. Reference:

You are trying to deploy a Connector in the AWScloud from NetApp Cloud Manager. The deployment fails
and shows the message 'Insufficient permissions to deploy Cloud Connector". You have verified the AWS
access key and the AWS secret key.
In this scenario, what Is the reason that the deployment failed?
- A. The Connector can be deployed only inAWS GovCloud (US).
- B. The user lacks the permission to deploy within Cloud Manager.
- C. No AWS Marketplace subscription is associated with Cloud Manager.
- D. The required Identity and Access Management (IAM) policies were not Installed.
正解：B
質問 # 41
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?
- A. Snapshot copies were manually removed from the destination after the resync.
- B. The autodelete option removed Snapshot copies before the resync.
- C. NetApp ON TAP System Manager removed these snapshot copies due to a snapshot schedule.
- D. Newer Snapshot copies than the common snapshot that was chosen for resync were removed automatically at the destination.
正解：D
解説：
= 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
質問 # 42
You are deploying NetApp ONTAP Select. When trying to add VMware vCenter to the inventory, you receive the message shown below.
Credential authentication failed for x.x.x.x with: HostConnectionFailed In this scenario, how would you correct this problem?
- A. Change the vCenter password.
- B. Change the IP address of the vCenter server.
- C. Change the gateway address of the ONTAP Select Deploy VM.
- D. Change the IP address of the ONTAP Select Deploy VM.
正解：D
解説：
The error message indicates that the ONTAP Select Deploy VM cannot connect to the vCenter server due to a network issue1.
One possible cause of this issue is that the IP address of the ONTAP Select Deploy VM is conflicting with another device on the same network2.
To correct this problem, you need to change the IP address of the ONTAP Select Deploy VM to a unique and valid address that can reach the vCenter server2.
You can change the IP address of the ONTAP Select Deploy VM by using the Deploy web interface or the Deploy CLI2.
After changing the IP address, you need to restart the Deploy services and re-add the vCenter server to the inventory2. Reference:
1: Credential authentication failed with: HostConnectionFailed, NetApp Knowledge Base
2: Changing the IP address of the Deploy VM, ONTAP Select 9 Documentation Center
質問 # 43
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 disk in Bay 0.
- B. Power cycle the shelf.
- C. Reseat the NSM100 module.
- D. Reseat the PSU of the shelf.
正解：C
解説：
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:
