NEW QUESTION # 35
Your customer calls you because one application is not able to access a NetApp ONTAP S3 bucket. While reviewing the EMS log on the cluster, you see the following message:
The same credentials work in another application.
In this scenario, what would cause this problem?
- A. The application is trying to log in as an anonymous user.
- B. The application is trying to access using the HTTP protocol.
- C. The application is using v2 signatures.
- D. The application is using v4 signatures.
Answer: C
Explanation:
The error message indicates that the access is denied for user 'anonymous user' (Vserver 50), from client IP 10.10.10.10 accessing resource '/offload-target'. This means that the application is not providing a valid user name or access key to authenticate with the ONTAP S3 server. According to the NetApp documentation1, ONTAP S3 server supports both v2 and v4 signatures, but v2 signatures are deprecated and not recommended. Therefore, the application should use v4 signatures to access the ONTAP S3 bucket. Additionally, the application should specify the bucket name in the host name, not in the resource path, as shown in the following example2:
https://bucket-name.s3-server-name.com/object-name

NEW QUESTION # 36
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. The 10 Gbps to 10 Gbps cluster Interconnect is creating a speed mismatch.
- D. There is an NXOS firmware mismatch, verify in the Interoperability Matrix (1MTJ for a supported version.
Answer: C
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 # 38
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. There was a failed PSU in the switchover site.
- B. The ISLs were down between the sites.
- C. An ISL link was not operating at 16Gbps.
- D. The site had unmirrored aggregates.
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 # 39
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 nodeshell using the node console and collect the core dumps from the nodeshell.
- B. Log in to the clustershell using the node console and collect the core dumps from the clustershell.
- C. Log in to the systemshell and collect core dumps from the systemshell.
- D. Log in to the service processor and collect the core dumps from the service processor.
Answer: C
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 # 40
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

NEW QUESTION # 41
You have a NetApp ONTAP cluster consisting of four NetApp FAS8200 controllers with two NetApp CN1610 cluster switches running ONIAP 9.8 software. You are receiving several alert messages stating that the cluster network has degraded. After troubleshooting, you determine that the errors are being generated from Node 2, interface e0b.
In this scenario, what should you do first to solve this problem?
- A. Replace both NetApp CN1610 switches.
- B. Replace the NetApp CN1610 switch that connects to Node 2, interface e0b.
- C. Replace the Twinax cable between Node 2, Interface e0b. and the NetApp CN1610 switch.
- D. Replace the motherboard on Node 2.
Answer: C
Explanation:
A Twinax cable is a type of copper cable that is used to connect cluster ports to cluster switches1.
A cluster port is a network port that is configured for cluster communication and data access2.
A cluster switch is a network switch that is used to interconnect the nodes in a cluster and provide redundancy and load balancing3.
A cluster network is a network that enables cluster communication and data access between the nodes in a cluster and external clients4.
A cluster network can be degraded due to various reasons, such as misconfiguration, malfunction, or excessive link errors on the cluster ports or the cluster switches.
Link errors are errors that occur on the physical layer of the network, such as CRC errors, length errors, alignment errors, or dropped packets.
Link errors can indicate a problem with the cable, the switch port, the network interface card (NIC), or the cable connector.
In this scenario, the alert messages state that the cluster network has degraded and the errors are being generated from Node 2, interface e0b.
The first step to solve this problem is to replace the Twinax cable between Node 2, interface e0b and the NetApp CN1610 switch, as this could be the source of the link errors.
Replacing the cable could resolve the issue and restore the cluster network to a healthy state.
If replacing the cable does not solve the problem, then other steps may be required, such as checking the switch port, the NIC, or the cable connector, or replacing the switch or the motherboard. Reference:

- C. Data aggregates will not be affected by B2B processing on another aggregate.
- D. During B2B processing, all I/O to the node is stopped.
Answer: C
NEW QUESTION # 44
The motherboard of Node-01 is being replaced. To perform this task, a takeover was Initiated from Node-02. Node-02 panics showing the string below.
PANIC; Permanent errors on all HA mailbox disks (while marshalling header) in SKprocess fnmbx_instanceWorker on release 9.5P8 (C) What has happened in this situation?
- A. While in maintenance mode, the mailbox destroy local command was executed.
- B. While in maintenance mode, the fcadmin device_map command was executed.
- C. While in maintenance mode, the HA_config show command was executed.
- D. While in maintenance mode, the sldiag device show command was executed.
Answer: A
Explanation:
The mailbox disks are the first two disks of the root aggregate on each node of an HA pair. They store the HA state information and the panic dump files. The mailbox disks are used for communication between the HA partners and for takeover and giveback operations1 The mailbox destroy local command is used to destroy the mailbox disks on the local node. This command is only available in maintenance mode and should be used with extreme caution. The command is intended for situations where the mailbox disks are corrupted or inaccessible and need to be recreated2 If the mailbox destroy local command is executed on a node that is in takeover mode, the node will panic with the message "Permanent errors on all HA mailbox disks". This is because the node will lose the HA state information and the panic dump files of the partner node, and will not be able to communicate with the partner node or perform a giveback operation3 Therefore, if the motherboard of Node-01 is being replaced, and a takeover was initiated from Node-02, and Node-02 panics showing the string "Permanent errors on all HA mailbox disks", the most likely cause is that the mailbox destroy local command was executed on Node-02 while in maintenance mode. This is a serious error that can result in data loss and system downtime4 Reference:

NEW QUESTION # 45
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?
- A. The maxdirsize Is exceeded in the ONTAP software.
- B. The inode limit is exceeded in the ONTAP software.
- C. All constituent volumes are full.
- D. The maximum number of volume constituents has been reached in the ONTAP software.
Answer: A
Explanation:
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 Documentation 2: How to increase the maxdirsize of a FlexVol volume - NetApp Knowledge Base

NEW QUESTION # 47
You have a 2-node NetApp FAS2750 switchless cluster with twenty-four 1.8 TB disks that is experiencing performance issues. Upon investigation, you discover several type B consistency points.
Referring to the exhibit, which corrective action would address these consistency points?
- A. Add an additional shelf of twenty-four 1.8 TB disks.
- B. Replace the twenty-four 1.8 TB disks with twelve 4 TB disks.
- C. Convert the 2-node switchless cluster to a 2-node switched cluster.
- D. Create additional data LIFs.
Answer: A
Explanation:
A type B consistency point (CP) is triggered when the NVRAM buffer is full and needs to be flushed to disk. A type B CP indicates that the write workload is higher than the disk throughput, and the system is experiencing back pressure1 A switchless cluster is a cluster configuration that does not use external switches for cluster interconnect and management network. A switchless cluster has lower bandwidth and redundancy than a switched cluster, and is limited to two nodes2 The exhibit shows the output of the sysstat -x command, which displays the system performance statistics in extended mode. The output shows that the system has high CPU utilization, high disk utilization, high NVRAM utilization, and several type B CPs. These are signs of performance issues and resource contention3 The best corrective action to address these consistency points is to add an additional shelf of twenty-four 1.8 TB disks. This will increase the disk capacity and throughput, and reduce the disk utilization and the frequency of type B CPs4 Creating additional data LIFs will not address the consistency points, because the data LIFs are used for data access protocols, not for NVRAM flushing5 Converting the 2-node switchless cluster to a 2-node switched cluster will not address the consistency points, because the cluster interconnect and management network are not related to the disk performance6 Replacing the twenty-four 1.8 TB disks with twelve 4 TB disks will not address the consistency points, because the disk throughput will not increase, and the disk utilization will remain high7 Reference:
