Which feature enables simultaneous snapshots of multiple LUNs In different volumes?
The feature that enables simultaneous snapshots of multiple LUNs in different volumes is Consistency Groups. This feature ensures that snapshots taken across different LUNs and volumes are consistent with each other, making it possible to recover a consistent state across multiple storage objects.

NetApp Documentation on Consistency Groups
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.

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).
When using tagged VLANs on Cisco Nexus switches for NVMe over TCP, which two changes must be made to enable jumbo frames? (Choose two.)
For enabling jumbo frames on Cisco Nexus switches for NVMe over TCP with tagged VLANs, the following changes are required:
Modify the Cisco Nexus switches to use an MTU of 9216: Setting the MTU to 9216 ensures that the network can handle jumbo frames, reducing the number of packets needed for large data transfers and thus improving performance.
Modify the appropriate broadcast domain in NetApp ONTAP software to use an MTU of 9216: This setting must match the network configuration to ensure end-to-end support for jumbo frames, which is essential for optimizing performance in NVMe over TCP environments.
For additional information, refer to:
NetApp Documentation on NVMe over TCP

An administrator is setting up a NetApp ONTAP AFF system for both NVMe/TCP and iSCSI. Which task is required for SAN configuration?
When setting up a NetApp ONTAP AFF system for both NVMe/TCP and iSCSI, a critical task required for SAN configuration is to configure Logical Interfaces (LIFs). LIFs are necessary for network connectivity and are used by both NVMe/TCP and iSCSI protocols to communicate between the storage system and the host.
The configuration of LIFs involves creating and managing these interfaces to ensure they are correctly mapped and available for use by the respective protocols. This step is essential for the SAN setup to function properly.
For more detailed steps on configuring LIFs, you can refer to NetApp's documentation:
How to Configure NVMe/TCP with ONTAP (NetApp Community).
