NS0-604: Hybrid Cloud - Architect

NetApp BlueXP tiering is the ideal solution for reducing total cost of ownership (TCO) by leveraging cloud storage. It enables automatic tiering of infrequently accessed data (cold data) from expensive on-premises storage to lower-cost object storage in the cloud (such as Azure Blob, AWS S3, or Google Cloud Storage). This reduces the need for high-performance, high-cost local storage for data that isn't frequently accessed, effectively lowering the overall storage costs.

By migrating cold data to more economical cloud storage tiers, BlueXP tiering helps organizations optimize their storage spend, thus reducing TCO for their on-premises third-party storage infrastructure.

Other solutions like BlueXP backup and recovery, copy and sync, and replication provide different services (such as data protection, data migration, and disaster recovery) but are not focused on cost reduction through tiering, which specifically helps reduce TCO.

For setting up disaster recovery in the Central US region for an existing Azure NetApp Files workload in the East US2 region, the customer should use cross-region replication. This feature allows data replication across different Azure regions, providing a robust disaster recovery solution by keeping a secondary copy of the data in a geographically separate location.

Cross-zone replication (A) deals with replication within the same region across availability zones. SnapMirror (B) and SyncMirror (C) are ONTAP-specific replication technologies but are not directly applicable to Azure NetApp Files in this scenario.

In a Multi-AZ (Availability Zone) setup for NetApp Cloud Volumes ONTAP in AWS, ensuring nondisruptive failover between nodes is critical for high availability. 'Floating IPs' are required for seamless failover between nodes in such a configuration.

Floating IPs allow the primary node to automatically transfer its IP address to the secondary node during a failover event, ensuring that clients can continue to access the service without needing to reconfigure anything. This mechanism enables clients to access the same IP regardless of which node in the cluster is actively serving requests, thus maintaining nondisruptive operations.

Elastic Network Interfaces (ENIs) facilitate networking in AWS but do not inherently handle IP floating between nodes for failover. Security groups and Intercluster UFs manage security and inter-node communication, respectively, but do not address the failover requirements. Floating IPs are explicitly designed to enable failover in high-availability cloud storage environments like NetApp Cloud Volumes ONTAP.

Thus, 'floating IPs' are the required network construct that allows for nondisruptive failover between nodes in a multi-AZ setup, ensuring continuous service availability even in the event of an outage in one availability zone.

When setting up NetApp Cloud Volumes ONTAP to tier to Amazon S3, minimizing infrastructure costs, especially egress charges, is critical. The best way to create a connection to S3 without incurring egress charges is by using an AWS gateway endpoint.

Gateway endpoints enable a private connection between Amazon S3 and your Amazon Virtual Private Cloud (VPC), eliminating the need for internet-based routing, which would incur data transfer charges (egress fees). With this private connection, data is transferred directly between the VPC and S3 without crossing the public internet, thus avoiding egress costs.

Other options such as peering and PrivateLink are viable for connecting VPCs but do not specifically address the elimination of egress charges when connecting to S3. A NAT device is also unnecessary for this scenario and would not eliminate egress charges but could instead introduce additional costs. Therefore, the gateway endpoint is the most cost-effective and direct method for achieving the desired outcome.

To get insights about which data to migrate from on-premises NetApp systems to Azure, the customer should use the Cloud Recommendations dashboard in NetApp BlueXP Digital Advisor. This dashboard analyzes the on-premises environment and provides recommendations on which workloads or datasets are best suited for migration to the cloud, such as to Azure.

Other dashboards like Valuable Insights (A) and Health Check (B) provide general system health and performance information, while Keystone Advisor (D) relates to NetApp's subscription-based storage offering.

For continuously scanning various data sources to ensure regulatory compliance, NetApp BlueXP Classification is the appropriate solution. This service helps organizations identify and classify sensitive data across their environments, ensuring that they meet compliance requirements such as healthcare regulations (HIPAA, for example).

Operational resiliency (A) focuses on system reliability, Digital advisor (B) offers system performance insights, and Ransomware protection (D) deals with security threats rather than compliance scanning.
