NEW QUESTION # 18
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 host with an IP address of 10.10.20.60 are in different initiator groups.
- 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 have the same IQN.
- 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 accessing the same LUN.
- D. 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.
Answer: B
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. Reference:
iSCSI Qualified Name (IQN) - NetApp
iSCSI authentication and authorization - NetApp

NEW QUESTION # 23
An administrator receives the following error message:
What are two causes for this error? (Choose two.)
- A. A disk is falling.
- B. There is excessive SATA HDD load.
- C. An SSD disk is performing garbage collection to create a dense data layout.
- D. There Is excessive SSD load causing the wear leveling to become unbalanced.
Answer: C,D
Explanation:
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:

NEW QUESTION # 24
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 storage failover giveback command on Site B.
- B. Enter the storage failover giveback command on Site A.
- C. Enter the metroclustor switchback command on Site B.
- D. Enter the metrocluster switchback command on Site A.
Answer: D
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. Reference:

NEW QUESTION # 26
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 10 Gbps to 10 Gbps cluster Interconnect is creating a speed mismatch.
- B. There is an NXOS firmware mismatch, verify in the Interoperability Matrix (1MTJ for a supportedversion.
- C. The AFF A300 Is using an adapter card for the cluster Interconnect, but only onboard ports are supported.
- D. AFF A300 and AFF A700 node mixing Isnot supported in ONTAP 9.8 software.
Answer: A
NEW QUESTION # 27

over across subnets.
How would youaccomplish this task?
- A. Configure an equal number of UFs on each subnet.
- B. Configure VIP LIFs using BGP.
- C. Configure a I IF failover policy for each subnet inside a single broadcast domain.
- D. Configure VIP LIFs using OSPF.
Answer: B
NEW QUESTION # 28
A customer's storage administrator Informs you about the deactivated Automatic Switchover (AUSO) feature on their MetroCluster IP environment.
What Information would you tell your customer in this scenario?
- A. The AUSO feature cannot be activated due to a non-mirrored aggregate.
- B. The AUSO feature is not available in Metrocluster IP installations by design.
- C. A faulty link automatically deactivated the AUSO feature.
- D. This is a configuration failure, you can activate that feature for the customer.
Answer: B
Explanation:
The AUSO feature is a MetroCluster functionality that enables an automatic switchover to the surviving site in the event of a disaster that affects one site1.
The AUSO feature is only available in MetroCluster FC configurations, which use Fibre Channel (FC) switches and FC-to-SAS bridges to connect the nodes and disk shelves across sites1.
MetroCluster IP configurations, which use Ethernet switches and network adapters to connect the nodes and disk shelves across sites, do not support the AUSO feature2.
Instead, MetroCluster IP configurations use the ONTAP Mediator service, which is a software component that monitors the health and connectivity of the MetroCluster nodes and initiates a Mediator-assisted unplanned switchover when a disaster occurs3.
The Mediator-assisted unplanned switchover is similar to the AUSO feature, but it requires the ONTAP Mediator service to be configured and running on a separate host3.
Therefore, you would tell your customer that the AUSO feature is not available in MetroCluster IP installations by design, and that they need to use the ONTAP Mediator service instead for disaster recovery. Reference:

NEW QUESTION # 29
A customer with an FC MetroCluster configuration that is running NetApp ONTAP 9.8 software experienced a site outage and wants to know why the MetroClusler configuration did not switch over to the other site.
What are two reasons for this problem? (Choose two.)
- A. An ISL link was not operating at 16Gbps.
- B. The site had unmirrored aggregates.
- C. There was a failed PSU in the switchover site.
- D. The ISLs were down between the sites.
Answer: B,D
Explanation:
A MetroCluster configuration requires the ISLs between the sites to be up and running for the switchover to occur. If the ISLs are down, the MetroCluster configuration cannot communicate with the other site and cannot perform the switchover. Additionally, a MetroCluster configuration requires all aggregates to be mirrored across the sites for data protection and availability. If a site has unmirrored aggregates, the switchover will fail because the data on those aggregates will not be accessible from the other site.

NEW QUESTION # 30
Your customer installed the shelf firmware for their NS224 shelf over a week ago, and the firmware has
notupgraded 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. Reseat the NSM100 module.
- C. Power cycle the shelf.
- D. Reseat the PSU of the shelf.
Answer: C
NEW QUESTION # 31
A customer wants to connect a NetApp AFF A700 system to a 40GbE switch. The controllers have a 10/40G Ethernet card in slot 4 for this purpose. The link comes up fine on node 2, but it will not come up on node 1. You look at the AutoSupport data for the nodes in question and see the output shown in the exhibit.
What is the cause of the customer's problem?
- A. The ports are configured for 4x10Gbit instead of 40Gbit.
- B. The cable is plugged in upside down.
- C. The port has an incorrect SFP inserted.
- D. The incorrect cable is used.
Answer: C
Explanation:
= The cause of the customer's problem is that the port has an incorrect SFP inserted. According to the AutoSupport data, the node 1 has a device type of XL710 BQ, which is a 40GbE adapter that requires a QSFP+ transceiver1. However, the part number of the adapter is 111-02590, which is a 10GbE adapter that requires a SFP+ transceiver2. This mismatch prevents the link from coming up on node 1. The customer should replace the adapter with the correct one or use a compatible transceiver for the existing adapter.
