NetApp NS0-604 Hybrid Cloud - Architect Exam Practice Test

Answer : A

For a company migrating a VMware environment to Azure using Azure VMware Solution (AVS), and where the workload requires more storage than compute, Azure NetApp Files is 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, and Amazon 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, but Azure NetApp Files (A) provides better performance and is specifically optimized for AVS.

Answer : C

The first step in implementing NetApp BlueXP backup and recovery for backing up on-premises data to Google Cloud is to install the NetApp BlueXP Connector. The Connector acts as a central management component that facilitates communication between your on-premises storage and the cloud storage provider (Google Cloud in this case). It is a key part of the BlueXP infrastructure and is essential for managing backups, replication, and tiering to the cloud.

Creating a Google Cloud bucket (A) is necessary but not the first step. NetApp Cloud Volumes Service (B) is used for different scenarios, not specifically for backups. Installing an Acquisition Unit (D) is related to monitoring and gathering data for systems like Cloud Insights, not for the BlueXP backup process.

Answer : A

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.

Answer : D

Azure NetApp Files volumes need to be placed in a specially purposed subnet within your Azure Virtual Network (VNet) to ensure proper isolation and security. This subnet must be delegated specifically to Azure NetApp Files services.

A delegated subnet in Azure allows certain Azure resources (like Azure NetApp Files) to have exclusive use of that subnet. It ensures that no other services or VMs can be deployed in that subnet, enhancing security and performance. Moreover, it ensures that the volumes are only accessible through private connectivity options like VNet peering or a Virtual Network Gateway, without any exposure to the public internet.

Subnets such as basic, default, or dedicated do not have the specific delegation capabilities required for Azure NetApp Files, making delegated the correct answer for this scenario.

Answer : A

NetApp AutoSupport requires outbound access to specific endpoints for delivering support data, and this communication occurs over HTTPS (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 like NFS/SMB traffic (B), SSH/RDP traffic (C), and DNS traffic (D) are irrelevant in this context, as AutoSupport only requires secure web traffic via HTTPS.

Answer : D

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.

Answer : A, D

To prevent security breaches like the one experienced by the company, where data was encrypted and Snapshot copies were deleted, two features are essential:

SnapLock (A): SnapLock is a feature that provides write once, read many (WORM) protection for files. It prevents the deletion or modification of critical files or snapshots within a specified retention period, even by an administrator. This feature would have protected the company's Snapshot copies by locking them, making it impossible to delete or alter them, thus preventing data loss during a ransomware attack.

Multi-Admin Verification (D): This feature requires approval from multiple administrators before critical operations, such as deleting Snapshots or making changes to protected data, can proceed. By requiring verification from multiple trusted individuals, it greatly reduces the risk of unauthorized or malicious actions being taken by a single user, thereby providing an additional layer of security.

While Snapshot technology (C) helps with regular backups, it doesn't protect against deliberate deletion, and Data Lock (B) is not a NetApp-specific feature for protecting against such breaches.
