NS0-604 Questions and Answers

NetApp Volume Encryption (NVE) is a feature used to encrypt data at the storage level, ensuring that sensitive information is protected even if the physical storage media is compromised. For this scenario, where the company mandates the use of NVE, adataStorage Virtual Machine (SVM) should be used.

Adata SVMis the entity that provides the actual data services in a NetApp ONTAP system, and it is where the volumes that require encryption reside. By leveraging NVE, the storage administrator can ensure that volumes hosted by the data SVM are encrypted, securing the data in transit and at rest.

Other types of SVMs, likenode,system, andadmin, are not used for hosting user data, so they would not be relevant in applying NetApp Volume Encryption. Adata SVMis designed for managing and securing the volumes that need encryption, making it the correct type for this use case.

To comply with the protocol that demands regular changes to access keys for the NetApp BlueXP Connector in AWS, the customer should useAWS automatic key rotation. AWS Key Management Service (KMS) can automatically rotate the keys used for accessing and managing the BlueXP Connector, ensuring compliance with security protocols without requiring manual intervention.

Manual updates via the UI (B)would require more effort and does not automate key rotation.The security admin tool (A)andAWS Key Management Service (D)are related to key management, but automatic key rotation through AWS simplifies the process by automating regular key changes.

To rapidly expand astorage-heavy VMware environmentusingAzure services, the company should utilize:

Azure VMware Solution (A): This service allows VMware workloads to be seamlessly migrated or expanded into Azure, providing a familiar environment with the scalability and flexibility of the Azure cloud. It's an ideal solution for extending on-premises VMware deployments to Azure.

Azure NetApp Files (D): Azure NetApp Files provides highly performant, scalable file storage in Azure. It integrates well with Azure VMware Solution, offering a robust storage backend for VMware workloads, especially when they are storage-heavy.

Amazon FSx for NetApp ONTAP (B)andGoogle Cloud VMware Engine (C)are not relevant in this Azure-specific scenario.

In this scenario, the life sciences customer is looking to deploy Azure VMware Solution (AVS) while leveraging Azure NetApp Files for high performance and proximity to their applications in the EAST US region. The two critical components to consider in this design are:

Ensuring that the Azure VMware Solution and Azure NetApp Files volumes are in the same Availability Zone (A): This is crucial to reduce latency and ensure optimal performance for high-performance workloads. Placing both AVS and Azure NetApp Files in the same zone ensures that data access is faster and more efficient due to reduced network hops and minimal latency.

Choosing the Azure UltraPerformance Gateway and enabling Azure ExpressRoute FastPath (C): To further optimize performance and provide dedicated, low-latency connectivity between AVS and Azure NetApp Files, using ExpressRoute with FastPath and the UltraPerformance Gateway ensures high bandwidth and lower network latencies. FastPath enables direct traffic flow between the on-premises network and the virtual network hosting AVS, bypassing the need for extra routing hops, thus improving performance.

Using dark sites (B) or public IP addresses (D) is not relevant in this case, as they do not contribute to performance optimization or the integration of Azure NetApp Files and AVS in the same region.

To prevent the deletion of volumes and snapshots by a rogue administrator without the option to assign a trusted administrator, the customer should implement:

SnapLock Enterprise (B): SnapLock is a feature that provides WORM (Write Once, Read Many) protection, ensuring that volumes or snapshots cannot be deleted or modified for a set retention period, even by administrators.

Tamperproof NetApp Snapshot copies (D): Snapshots in ONTAP can be made tamperproof to protect data from deletion or modification, securing them against rogue administrators.

Multi-admin verification (A)requires approval from multiple administrators, which the customer does not want.Role-based access control (C)helps manage permissions but does not provide protection against a rogue administrator with elevated permissions.

NetApp Cloud Volumes ONTAPsupportsNetApp Volume Encryption (NVE)with the cloud provider's key vault for encryption key management. NVE provides encryption at the volume level and integrateswith external key management systems, such as AWS KMS, Azure Key Vault, and Google Cloud KMS, making it the appropriate encryption solution for cloud deployments.

NetApp Aggregate Encryption (NAE) (C)is used for on-premises environments.Transparent Data Encryption (TDE) (A)is commonly used for database encryption, andOnboard Key Manager (OKM) (B)is a different key management solution not tied to cloud key vaults.

For a company migrating a VMware environment to Azure usingAzure VMware Solution (AVS), and where the workload requires more storage than compute,Azure NetApp Filesis the most suitable datastore storage solution. Azure NetApp Files offers high performance, scalability, and is fully integrated with Azure, making it ideal for large-scale workloads that require extensive storage capacity but less compute.

Azure Files (B)is generally not sufficient for high-performance VMware workloads, andAmazon FSx for NetApp ONTAP (C)is an AWS-based solution, not an Azure-compatible service.Cloud Volumes ONTAP (D)in Azure can be used for certain storage needs, butAzure NetApp Files (A)provides better performance and is specifically optimized for AVS.

To update or rotate security keys for one of their acquisition units inNetApp BlueXP observability, the customer should use theSecurityAdmin tool. This tool is designed to manage security-related configurations, including key updates and rotations, ensuring secure management of encryption keys and certificates.

User Management (B)handles user roles and access,Cloud Central (C)is for general cloud services management, and theWorkload Security menu (D)focuses on security monitoring and enforcement rather than key management.

Google Cloud NetApp Volumes(formerly known as NetApp Cloud Volumes Service) is the best storage solution for an AI workflow that requires NFSv4.1 support, minimal management requirements, data protection, and the ability to rapidly create clones of datasets. This service provides fully managed file storage with NFS support and integrates seamlessly with Google Cloud, offering features like snapshotting, cloning, and built-in data protection.

NetApp Cloud Volumes ONTAP (B)is also a strong option but requires more management than Google Cloud NetApp Volumes.Google local SSD (C)andGoogle Cloud Storage (D)don't meet the requirements for NFSv4.1 support and dataset cloning.

NetApp AutoSupport requires outbound access to specific endpoints for delivering support data, and this communication occurs overHTTPS (port 443). The two provided NetApp AutoSupport URLs are accessed via secure HTTP (HTTPS), so the company must configure routing and firewall policies to allow outbound HTTPS traffic.

Blocking HTTPS traffic by default would prevent the AutoSupport service from functioning, which is critical for sending diagnostic information to NetApp support for monitoring and troubleshooting.

Options likeNFS/SMB traffic (B),SSH/RDP traffic (C), andDNS traffic (D)are irrelevant in this context, as AutoSupport only requires secure web traffic via HTTPS.

When deploying NetApp Cloud Volumes ONTAP on Amazon Web Services (AWS), for applications that uselarge sequential I/O, the key workload characteristic used for sizing Amazon Elastic Block Store (Amazon EBS) isMBps (megabytes per second). Large sequential I/O workloads, such as video streaming or backup operations, typically require high throughput rather than high IOPS (input/output operations per second).

Capacity (A)andIOPS (B)are important for other types of workloads, such as databases, whileCPU (C)is related to processing power but not specific to large sequential I/O. For these workloads, throughput, measured in MBps, is the critical sizing metric.

To get insights about which data to migrate from on-premises NetApp systems to Azure, the customer should use theCloud Recommendationsdashboard 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 likeValuable Insights (A)andHealth Check (B)provide general system health and performance information, whileKeystone Advisor (D)relates to NetApp’s subscription-based storage offering.

The appropriate NetApp feature to use in this scenario is aCloud Storage Pool. A Cloud Storage Pool in NetApp StorageGRID allows the administrator to tier data to public clouds like Amazon S3 Glacier Deep Archive. This feature lets the administrator keep local replicated copies for performance, geo-dispersederasure-coded copies for durability, and tier cold or backup data to Glacier for long-term retention and cost savings.

FabricPool (B)andFlash Pool (C)are not relevant to S3 data tiering and bucket replication in StorageGRID.Dynamic Disk Pool (D)is more applicable to disk management in traditional storage arrays, not for managing S3 bucket replicas across different storage locations.

To analyze IOPS, throughput, latency, and capacity utilization of a Cloud Volumes ONTAP HA cluster in Google Cloud, the two BlueXP solutions that provide these metrics are:

BlueXP Digital Advisor (D): This tool provides detailed insights into system performance, including IOPS, throughput, latency, and capacity utilization. It is designed to give administrators a comprehensive view of their cloud-based storage environments to help optimize performance.

BlueXP Tiering (B): While primarily used for data tiering, BlueXP Tiering also offers metrics related to capacity utilization and performance. It helps monitor storage usage and can provide insights into how data tiering affects system performance.

Other options likeBlueXP Classification (A)focus more on data governance and classification, whileBlueXP Edge Caching (C)is designed for optimizing data access at edge locations and doesn’t provide the full suite of performance metrics needed for detailed analysis.
