質問 # 15
A customer requires multiple SAN and NAS protocols on a NetApp AFF cluster. The cluster must concurrently serve a namespace over NVMe/FC, a LUN over FCP, a LUN over iSCSI, and an NFS export.
Based on these requirements, what is the minimum data SVM count that is required?
- A. 0
- B. 1
- C. 2
- D. 3
正解：C
解説：
To concurrently serve a namespace over NVMe/FC, a LUN over FCP, a LUN over iSCSI, and an NFS export, only one data SVM (Storage Virtual Machine) is required. NetApp ONTAP allows a single SVM to supportmultiple SAN and NAS protocols simultaneously, enabling efficient and consolidated management of storage resources.

質問 # 16
An administrator configured an SVM with LUNs with two WWPNs per node. The administrator accidentally created a WWPN on node1that needs to move to node2. The SAN hosts use ALUA.
Based on this requirement, what must be taken offline to correct the situation?
- A. Volume
- B. LIF
- C. LUN
- D. SVM
正解：B
解説：
To move a WWPN from node1 to node2 in a NetApp ONTAP SAN environment where ALUA is used, you must take the Logical Interface (LIF) offline. Modifying LIFs involves changing their assignment between nodes, which requires them to be temporarily offline. This ensures that the path states are correctly updated without causing disruption to the SAN hosts.
For more details, see:
* NetApp Community on Moving LIFs
* NetApp Documentation on SAN LIFs
質問 # 17
What is the maximum size for a LUN in NetApp ONTAP 9.14.1 software?

- C. 16TiB
- D. 128TiB
正解：D
解説：
In NetApp ONTAP 9.14.1 software, the maximum size for a LUN is128TiB. This limit ensures that large datasets can be stored and managed efficiently within a single LUN, catering to the needs of high-capacity SAN environments
質問 # 18
What Is the storage construct that enables an NVMe client to store data in an SVM?
- A. Namespace
- B. LUN
- C. Subsystem
- D. FlexGroup volume
正解：C
解説：
In an NVMe environment, the storage construct that enables an NVMe client to store data in an SVM (Storage Virtual Machine) is aSubsystem. A subsystem is a collection of one or more namespaces, which are used to store data. This abstraction allows for efficient management and scaling of NVMe storage within the ONTAP environment.

質問 # 22
An administrator runs the lun igroup show -insrar.ee command on a NetApp ONTAP SAN.
Based on the output, what is the initiator type?
- A. NQN
- B. IQN
- C. WWPN
- D. WWNN
正解：C
解説：
Based on the output of the command lun igroup show -instance, which lists the protocol as fcp and the initiator as server1.netapp.com, the initiator type is WWPN (World Wide Port Name). In Fibre Channel Protocol (FCP) environments, WWPNs are used to uniquely identify Fibre Channel devices. This contrasts with IQNs used in iSCSI, and NQNs used in NVMe over Fabrics.

質問 # 23
A storage administrator wants to increase security and optimize performance in a recently implemented SAN deployment.
What should the storage administrator configure to ensure initiator restriction to certain LIFs?
- A. Subnets
- B. Access list
- C. Network route
- D. Broadcast domain.
正解：B
解説：
To increase security and optimize performance in a SAN deployment, configuring an access list is essential.
Access lists restrict initiator access to specific LIFs, ensuring that only authorized hosts can connect to the storage system. This helps in enhancing security by preventing unauthorized access and optimizes performance by controlling and managing the paths used for storage access.
For additional details, you can refer to:
* NetApp SAN Administration Guide
質問 # 24

- B. volume fileclonecreate
- C. lun wovestart
- D. volumeclone create
正解：D
解説：
To clone a LUN from a SnapMirror destination volume for testing purposes, the volume clone create command should be used. This command creates a FlexClone volume from the SnapMirror destination, making the LUN within it accessible for testing without disrupting the original volume.
For more details, refer to:
* NetApp Documentation on Volume Clone Create
* NetApp Community Discussion on LUN Cloning

質問 # 28
What needs to be done to create a consistent Snapshot copy of a LUN without disruptions?
- A. Quiesce I/O to the LUN.
- B. Ensure that the LUN Is unmapped from the host.
- C. Map the LUN to a host.
- D. Ensure that the LUN is the only one in the volume.
正解：A
解説：
To create a consistent Snapshot copy of a LUN without disruptions, it is necessary to quiesce I/O to the LUN.
This process involves pausing or temporarily stopping the input/output operations to ensure that the data is in a consistent state when the snapshot is taken. This method is crucial for maintaining data integrity and consistency in the snapshot.

* NetApp Documentation on Snapshot Consistency
* NetApp Best Practices for Snapshot Management
質問 # 29
What Is modified when moving a LUN between different HA pairs in the same SVM to prevent loss of connectivity?
- A. reporting nodes
Cigroup - B. LUN mapping
- C. port name
正解：A
解説：
When moving a LUN between different HA pairs in the same SVM to prevent loss of connectivity, the reporting nodes must be modified. The reporting nodes configuration ensures that the initiator paths are properly updated to reflect the new physical location of the LUN. This prevents disruptions in connectivity by maintaining the correct pathing information for the host systems accessing the LUN.
For more details, refer to:
* NetApp Documentation on LUN Management
質問 # 30

A storage engineer in SAN environment needs to Identify FC ports using the company-wide naming policy.
Which command will accomplish this task?
- A. network interface modify
- B. ucadmin modify
- C. TCP portname set
- D. vserver fcp wwpn-alias set
正解：D
解説：
The vserver fcp wwpn-alias set command is used to set or modify the World Wide Port Name (WWPN) aliases for Fibre Channel (FC) ports in a NetApp ONTAP environment. This command allows you to apply a company-wide naming policy to FC ports, ensuring consistent and easily identifiable naming conventions across your storage infrastructure.
For further details, you can refer to:
