NEW QUESTION # 11
A customer is calling you to troubleshoot why users are unable to connect to their CIFS SVM.
Referring to the Information shown in the exhibit, what Is the source of the problem?
- A. The databases On Node03 must be Switched from secondary to master.
- B. The aggregate aggr2 has a failed disk.
- C. The broken disk in Node03 is the source of the problem.
- D. The v1db database is offline.
Answer: C
Explanation:
The broken disk in Node03 is causing the cluster ring to be offline, which prevents the CIFS SVM from being accessible. The cluster ring is a distributed database that stores cluster configuration information and enables communication between cluster nodes. If the cluster ring is offline, the cluster cannot function properly and the CIFS SVM cannot serve data to clients. The other options are not relevant to the CIFS SVM connectivity issue.

NEW QUESTION # 12
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 IP address of the ONTAP Select Deploy VM.
- B. Change the vCenter password.
- C. Change the gateway address of the ONTAP Select Deploy VM.
- D. Change the IP address of the vCenter server.
Answer: A
Explanation:
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:

NEW QUESTION # 13
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. NAS data UFs are accessible on only the node that has Epsilon.
- B. Both nodes race to takeover the other, one node will takeover the other node.
- C. No takeover event will occur and NAS data UFs will not be accessible.
- D. All nodes in the cluster reset and NAS data UFs are not accessible after reboot.
Answer: A
Explanation:
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.

NEW QUESTION # 14
After a normal power down of both nodes for building maintenance, Node01 of a 2-node cluster cannot be powered back up; however, all disk shelves are powered.
Which action should be performed to bring the cluster online and allow Node02 to serve data?
- A. Recreate the cluster with the system configuration recovery cluster recreate -from node command.
- B. Reboot the node With the system node reboot -node Node02 -bypass-optimization true command.
- C. Perform a takeover with the storage failover takeover -ofnode Node01 -option force command.
- D. Reinitialize the cluster with option 4a from the boot menu.
Answer: C
Explanation:
= The correct action to bring the cluster online and allow Node02 to serve data is to perform a takeover with the storage failover takeover -ofnode Node01 -option force command. This command will force Node02 to take over the resources of Node01 and serve the data from both nodes. This is necessary because Node01 is not responding and cannot initiate a graceful takeover. The other options are not correct because they will either destroy the existing cluster configuration (A and D) or reboot the node without taking over the resources of the other node (B).

NEW QUESTION # 15
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. NetApp ON TAP System Manager removed these snapshot copies due to a snapshot schedule.
- B. The autodelete option removed Snapshot copies before the resync.
- C. Snapshot copies were manually removed from the destination after the resync.
- D. Newer Snapshot copies than the common snapshot that was chosen for resync were removed automatically at the destination.
Answer: D
Explanation:
= 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
NEW QUESTION # 16

problem involves only their older Windows XP clients and some printers and scanners.
In this scenario, which statement Is correct?
- A. These systems use Offloaded Data Transfer, which is an unsupported feature in FlexGroup.
- B. FlexGroup requires CIFS shares to be located in qtrees, which these clients do not support.
- C. These systems use the SMQI protocol which Is an unsupported feature in FlexGroup
- D. FlexGroup requires CIFS shares to use the Continuously Available Feature, which these clients do not
support.
Answer: D
NEW QUESTION # 17
When you review performance data for a NetApp ONTAP cluster node, there are back-to-back (B2B) type consistency points (CPs) found occurring on the loot aggregate.
In this scenario, how will performance of the client operations on the data aggregates be affected?
- A. During B2B processing, clients will be unable to write data.
- B. During B2B processing, clients will be unable to read data.
- C. During B2B processing, all I/O to the node is stopped.
- D. Data aggregates will not be affected by B2B processing on another aggregate.
Answer: D
Explanation:
A B2B type consistency point (CP) occurs when a new CP is triggered before the previous CP is completed, due to the second memory buffer reaching a watermark. This can cause write latency to increase as user write operations are not replied until a write buffer frees up. However, this only affects the aggregate that is undergoing the B2B processing, and not the other aggregates on the same node. Therefore, the performance of the client operations on the data aggregates will not be affected by B2B processing on the root aggregate.

NEW QUESTION # 19
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. ONTAP Shutdown BBSP:C=00 L=2F FIFO:
- B. 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
- C. before Reset BBSP:C=00 L=00 FIFO:
- D. BIOS exit BBSP:C=2F L=20 FIFO: 2 C8 C9 C4 24 4 6 18 7 8 11
Answer: B
Explanation:
= 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.

NEW QUESTION # 20
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. The AFF A300 Is using an adapter card for the cluster Interconnect, but only onboard ports are supported.
- C. AFF A300 and AFF A700 node mixing Is not supported in ONTAP 9.8 software.
- D. There is an NXOS firmware mismatch, verify in the Interoperability Matrix (1MTJ for a supported version.
Answer: A
Explanation:
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:

NEW QUESTION # 25
You receive the "Unable to connect to the management gateway server" error when trying to connect to a node management IP.
In this situation, how do you determine whether core dumps are generated for the mgwd user space process?
- A. Log in to the service processor and collect the core dumps from the service processor.
- B. Log in to the nodeshell using the node console and collect the core dumps from the nodeshell.
- C. Log in to the clustershell using the node console and collect the core dumps from the clustershell.
- D. Log in to the systemshell and collect core dumps from the systemshell.
Answer: D
Explanation:
The mgwd user space process is responsible for managing the cluster configuration and providing the management interface for ONTAP. If this process crashes, it may generate a core dump file in the /mroot/etc/mgwd/core directory of the node. To access this directory, you need to log in to the systemshell, which is a Linux shell that runs on the node. The systemshell can be accessed by logging in to the nodeshell using the node console and then running the systemshell command. The nodeshell is a custom shell that provides access to ONTAP commands and utilities. The service processor and the clustershell are not relevant for collecting core dumps from the mgwd process. Reference = ONTAP 9 Cluster Administration, page 29-30; ONTAP 9 Troubleshooting Guide, page 23-24.
NEW QUESTION # 26
Your customer is running a NetApp AFF A800 system with NetApp ONTAP 9.8 software and states that their NS224 shelf is not showing with the correct shelf ID. You analyze the data and the shelf shows an identification of "1.SHFHUXXXXXXXXXX." What is the cause of the reported Issue?
- A. The shelf has been power cycled.
- B. The shelf had a disk replaced too quickly.
- C. The shelf was cabled Incorrectly.
- D. A new shelf was added to the controller.
Answer: C
Explanation:
According to the NetApp Knowledge Base, adding a second NS224 shelf to an existing stack can cause the first shelf ID to change to the serial number if the cables are not connected properly1. This can also result in a Medium Impact error message: Shelves with both connections via the same SAS path detected2. This situation is not normal for a NetApp AFF A800 system and can affect performance and availability. The cables should be reconnected according to the SAS cabling rules and concepts for shelves with IOM12/IOM12B modules3 and the controller-to-stack cabling worksheet template for quad-pathed connectivity4.
