A healthcare customer wants to Implement an FC SAN solution consisting of a NetApp ONTAP system, Broadcom switches, and servers.
Which tool contains detailed blueprints and implementation references that can be used to design this solution?
The correct tool for designing an FC SAN solution consisting of a NetApp ONTAP system, Broadcom switches, and servers is the 'NetApp Verified Architecture' (NVA). The NetApp Verified Architecture provides comprehensive blueprints and detailed implementation references. These blueprints are thoroughly tested, prescriptive in nature, and designed to minimize deployment risks and accelerate time to market. They are specifically designed to help ensure that the architecture meets the high standards required for enterprise environments.
NVA documents include design guides, best practices, and detailed configuration steps, making them invaluable for planning and deploying complex solutions like the one described.
For more information, you can refer to the official NetApp documentation on NetApp Verified Architectures:
NetApp Verified Architecture Program Summary
NetApp Verified Architecture Overview
These resources provide detailed insights into the architecture, including technology requirements, deployment procedures, and additional references for further reading.
A storage administrator recently implemented ISCSI SAN in a customer environment. Which two actions should be done to ensure the best performance? (Choose two.)
To ensure the best performance in an iSCSI SAN implementation:
Connect host and storage ports to the same switches: This minimizes latency and maximizes the efficiency of data paths by ensuring direct connections within the same network segment.
Configure Jumbo frames in the entire data path: Setting a larger Maximum Transmission Unit (MTU) size reduces the overhead for processing each packet, thus improving overall network performance. Ensuring Jumbo frames are configured end-to-end in the data path is crucial for optimal performance.

A storage engineer in SAN environment needs to Identify FC ports using the company-wide naming policy. Which command will accomplish this task?
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.

A customer has a 10GB volume with an 8GB LUN that is using 7GB. The snapshot policy is hourly and retains 48 snapshots. After a ransomware attack that encrypts all files on the LUN, the customer notices that all snapshots are gone.
What could cause this behavior?
The likely cause for the disappearance of all snapshots after a ransomware attack that encrypted all files on the LUN is the Snapshot autodelete feature. When the volume becomes full due to the encryption, the autodelete feature removes older snapshots to free up space, preventing the volume from running out of space and ensuring write operations can continue.
For more information, see:
NetApp Documentation on Snapshot Autodelete
NetApp Community Discussion on Snapshot Deletion
Which two NetApp features provide synchronous data replication between two sites for SAN workloads with automatic failover in case of a site disaster? (Choose two.)
For synchronous data replication between two sites with automatic failover in case of a site disaster for SAN workloads, the two NetApp features that provide these capabilities are SnapMirror Synchronous and MetroCluster IP.
SnapMirror Synchronous: This feature provides volume-granular, synchronous replication with zero RPO (Recovery Point Objective), ensuring that data is mirrored in real-time to a secondary site. This setup supports automatic failover, maintaining data availability even during site failures
MetroCluster IP: This solution provides synchronous replication and combines high availability and disaster recovery capabilities. MetroCluster IP uses IP networking to extend the distance over which replication can occur and supports automatic failover and failback, making it suitable for critical SAN workloads
