When using FCP, what is the minimum number of FC switches needed to redundantly attach three ESXi hosts?
When using Fibre Channel Protocol (FCP), the minimum number of FC switches needed to redundantly attach three ESXi hosts is 2. This setup ensures that each host has multiple paths to the storage, providing high availability and fault tolerance. Each ESXi host should be connected to both switches, allowing for continuous operation even if one switch fails.

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?
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.

What should an administrator use to protect an Oracle RAC Automatic Storage Management (ASM) instance to ensure automated restores?
To protect an Oracle RAC Automatic Storage Management (ASM) instance and ensure automated restores, the recommended tool is the NetApp SnapCenter plugin. SnapCenter provides comprehensive backup, restore, and clone capabilities for Oracle databases, including those using ASM. It integrates tightly with Oracle RAC environments and automates the entire data protection process, ensuring that backups are consistent and restores are efficient and reliable.

During expansion planning for a 10-node cluster running NetApp ONTAP 9.14.1 software, which uses SAN and NAS, how many additional nodes can be added to this cluster?
NetApp ONTAP 9.14.1 supports up to a 16-node cluster for SAN and NAS configurations. Given a current 10-node cluster, you can add up to 6 additional nodes to reach the maximum supported node count. This expansion capability ensures scalability for growing storage needs while maintaining high availability and performance.

An engineer Is implementing a data migration scenario for a customer who has multiple FC LUNs across multiple third-party SAN arrays. The engineer wants to use Foreign LUN Import (FLI) for the migration.
What is a requirement on the destination NetApp ONTAP cluster for FLI?
When using Foreign LUN Import (FLI) for migrating LUNs from third-party SAN arrays to a NetApp ONTAP system, one of the requirements is to have at least one Fibre Channel (FC) port configured in target mode on the destination NetApp ONTAP cluster. This configuration is necessary to facilitate the migration process as the target mode port will accept and manage incoming data from the source SAN arrays.
