List of questions
Question 31

What Is a recommended setting for using the NetApp ONTAP LUN fractional reserve?
The recommended setting for using the NetApp ONTAP LUN fractional reserve is to set the space guarantee to 'volume'. This setting ensures that the required space for overwrites in the volume is reserved, preventing potential write failures when snapshot copies are created. This setup helps in maintaining the performance and reliability of the storage system by ensuring there is always enough space allocated for the LUN.
For further details, you can refer to:
NetApp Community Discussion on Fractional Reserve
NetApp Documentation on Space Management
Question 32

An administrator creates a new volume and a LUN for an SAN-connected application that uses snapshots. The application has fast-growing data that is constantly being populated and deleted afterwards.
Which option can be set to manage the space automatically?
To manage space automatically for a volume containing a LUN with fast-growing data, enabling automatic resizing on the volume is recommended. This feature allows the volume to grow dynamically as needed, accommodating the fluctuating data size without manual intervention. This helps in managing storage efficiently and ensures that the application has the required space.

NetApp Community Discussion on Automatic Resizing
Question 33

A site survey has been conducted for an installation of a switchless HA pair with two NetApp DS224C shelves in the customer's already populated rack.
Which of the following two need to be verified to ensure a successful deployment? (Choose two.)
For a successful deployment of a switchless HA pair with two NetApp DS224C shelves in an already populated rack, it is crucial to verify:
Rack units: Ensure that there are enough rack units available to accommodate the new shelves and any associated equipment. Proper planning of space in the rack is essential for a neat and functional setup.
Power connections: Verify that there are sufficient and appropriately rated power connections available. Ensuring proper power distribution and redundancy is critical for the reliability and uptime of the storage system.

Question 34

A customer opens a support case for performance issues with an FC Oracle database after migrating from a NetApp AFF system to a NetApp All SAN Array (ASA) platform. Further investigation shows that the number of paths exceeds the recommendation for SAN deployment.
What are two ways to address this problem? (Choose two.)
When the number of paths exceeds the recommended configuration for SAN deployment, it can cause performance issues. To address this problem, you can:
Use Selective LUN Mapping (SLM): SLM allows you to control which LIFs (Logical Interfaces) are used to access specific LUNs, thus reducing the number of paths and potentially improving performance by aligning with best practice configurations.
Reconfigure the fabric switch zoning: Adjusting the zoning on the fabric switches can help manage and optimize the number of paths, ensuring that there are not too many paths that could lead to inefficient I/O operations and performance degradation.

Question 35

What Is the storage construct that enables an NVMe client to store data in an SVM?
In an NVMe environment, the storage construct that enables an NVMe client to store data in an SVM (Storage Virtual Machine) is a Subsystem. 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.
For further information, refer to:
NetApp NVMe/FC Configuration (NetApp).
Question 36

An administrator finishes an installation of a new NetApp ASA system at the customer site and creates a new LUN. The customer wants to restrict the access of the LUN to specific UFs.
Where would the administrator configure this?
To restrict access to a newly created LUN to specific hosts, the administrator should configure the igroup (initiator group). An igroup is used to control which initiators (hosts) are allowed to access specific LUNs. This ensures that only authorized hosts can access the storage, enhancing security and access control.
For more details, refer to:
NetApp Documentation on iGroups (NetApp).
Question 37

A customer wants to enable CHAP authentication on their iSCSI sessions.
Which command should be used to set up the appropriate security policies and passwords?
To enable CHAP (Challenge-Handshake Authentication Protocol) authentication on iSCSI sessions, the command vserver iscsi security create should be used. This command sets up the necessary security policies and passwords required for CHAP authentication, ensuring secure access to iSCSI targets.
For more details, refer to:
NetApp Documentation on iSCSI Configuration (NetApp).
Question 38

Which two steps must be taken first to restore a LUN from a SnapMirror Synchronous destination? (Choose two.)
To restore a LUN from a SnapMirror Synchronous destination, the following steps must be taken:
Release the relationship: This step is necessary to break the SnapMirror relationship, allowing the LUN to be restored independently.
Delete the relationship: After releasing the relationship, deleting it ensures that there are no residual dependencies or configurations that might interfere with the restore process.
For more information, refer to:
NetApp Documentation on SnapMirror Synchronous (NetApp) (NetApp).
Question 39

An administrator configured an SVM with LUNs with two WWPNs per node. The administrator accidentally created a WWPN on node1 that needs to move to node2. The SAN hosts use ALUA.
Based on this requirement, what must be taken offline to correct the situation?
Question 40

A customer Is setting up a four-node NetApp AFF cluster for use with NVMe/TCP and wants to use automatic host discovery.
Which protocol is used for the discovery of controllers?
