NS0-604 Hybrid Cloud - Architect Exam Questions and Answers

The issue where the Linux client shows that the NFS volume is full, despite the AWS dashboard showing available capacity in the Amazon FSx for NetApp ONTAP file system, suggests that the allocated volume size within ONTAP is smaller than the total capacity available. To resolve this, the customer shouldenable volume autosizing. Autosizing allows the volume to automatically increase in size as needed, preventing issues where the volume becomes full while the underlying file system still has available storage.

Increasing the capacity of the file system (B)is not necessary since the file system already has free space.Deleting snapshots (C)can free up some space, but autosizing is a more efficient solution.Tiering cold data (D)addresses long-term storage management but won’t resolve the immediate issue of the volume being full.

The company is migrating data from a 6-node, on-premises NetApp FAS cluster toNetApp Cloud Volumes ONTAPand determined that they can consolidate to two HA pairs. This means that the minimum number of Cloud Volumes ONTAP instances required is2, as each HA pair corresponds to one instance.

1 instance (A)would not provide the required redundancy and performance, and6 instances (B)or4 instances (D)are unnecessary given the performance sizing results.

To enhance the performance when tiering data fromNetApp ONTAP clustersto the Microsoft Azure cloud platform, the following best practices should be considered:

Establish a VNet service endpoint to Azure storage (A): This ensures secure and optimized access to Azure Blob storage directly from the ONTAP cluster, minimizing latency.

Create an Azure ExpressRoute connection (B): ExpressRoute provides a dedicated, high-performance connection between the on-premises ONTAP clusters and Azure Blob storage, reducing latency and increasing throughput.

Whilechoosing the IPspace (C)is important for network configuration, it doesn’t directly enhance performance for cloud-tiering.An HTTPS connection over port 443 (D)is for secure data transfer but isn’t specifically performance-enhancing.

The first step in implementing NetApp BlueXP backup and recovery for backing up on-premises data to Google Cloud is toinstall 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.

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 bedelegatedspecifically to Azure NetApp Files services.

Adelegated subnetin 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 asbasic,default, ordedicateddo not have the specific delegation capabilities required for Azure NetApp Files, makingdelegatedthe correct answer for this scenario.

In this scenario, the customer has 100TB of used capacity on an on-premises AFF volume, and 80% of the data is cold and tiered to Amazon S3 usingBlueXP tiering. After tiering, 80TB of cold data is tiered to Amazon S3, leaving 20TB of hot data on the AFF system. WhenBlueXP backup and recoveryperforms the first full backup, it backs up all the data (100TB). Since the backup is a full copy and independent of the tiering process, the total ingress traffic into AWS is80TB (tiered data) + 100TB (full backup), resulting in180TBof total ingress.

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.

NetApp BlueXP (formerly Cloud Manager) provides a comprehensive backup and recovery solution that supports various data sources. For customers looking to back up their on-premises data to Microsoft Azure Blob storage, the following data sources are supported:

NetApp ONTAP Volume Data: BlueXP backup and recovery can efficiently back up volumes created on NetApp ONTAP systems. This is a primary use case, ensuring that on-premises ONTAP environments can be backed up securely to cloud storage like Azure Blob, which offers scalability and cost-efficiency.

NetApp ONTAP S3 Data: NetApp ONTAP supports object storage using the S3 protocol, and BlueXP can back up these S3 buckets to cloud storage as well. This allows for a seamless backup of object-based workloads from ONTAP systems to Azure Blob.

Microsoft SQL Server and Azure Stack are not directly supported by NetApp BlueXP backup and recovery, as it focuses specifically on ONTAP environments and data sources.

For a NetApp BlueXP Connector deployed inRestricted Mode, the following two network requirements must be met:

Outbound connectivity to the BlueXP SaaS layer (A): Even in Restricted Mode, the BlueXP Connector needs outbound internet access to communicate with the BlueXP SaaS layer for updates, telemetry, and licensing information.

Connectivity to resources in your target networks (C): The BlueXP Connector must have network access to the resources (e.g., NetApp Cloud Volumes ONTAP instances or other managed systems) that it is supposed to manage or monitor.

Inbound connectivity (B)from the BlueXP SaaS layer is not required in Restricted Mode, as the mode is designed to minimize external access.User access (D)to the BlueXP SaaS layer is a user interface consideration but not a network requirement for the connector itself.

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 ofunauthorized or malicious actions being taken by a single user, thereby providing an additional layer of security.

WhileSnapshot technology (C)helps with regular backups, it doesn’t protect against deliberate deletion, andData Lock (B)is not a NetApp-specific feature for protecting against such breaches.

When managing NetApp Cloud Volumes ONTAP in Azure, administrators should log intoNetApp BlueXP(formerly Cloud Manager) to add disks to the aggregate. BlueXP provides a centralized management interface that allows administrators to add storage and manage resources easily. The process for expanding capacity in a Cloud Volumes ONTAP HA pair is best performed via BlueXP, which simplifies the disk addition process and ensures proper configuration within the HA architecture.

UsingSSH (A or B)is not the standard method for managing Cloud Volumes ONTAP resources.Azure Blob containers (C)are used for object storage and are not relevant for adding disks to Cloud Volumes ONTAP aggregates.

NetApp Keystone Storage as a Service (STaaS) offers various service levels depending on performance and latency requirements. For workloads that require less than 2ms latency, the two relevant service levels are:

Extreme (A): This service level is designed for the most latency-sensitive and high-performance workloads. It provides ultra-low latency (<2ms) and is ideal for applications that demand top-tier performance.

Premium (C): The Premium service level also supports low latency, typically less than 2ms, making it suitable for workloads with moderate to high performance requirements.

Standard (B)andPerformance (D)service levels provide higher latency and are not suitable for workloads requiring less than 2ms latency.

To protect data against abnormal behavior for NetApp ONTAP file systems and NetApp Cloud Volumes ONTAP, and to monitor volume workload activity and data entropy, the customer should use the following two solutions:

Cloud Insights Storage Workload Security (A): This solution offers monitoring and security analytics, which can detect abnormal behavior, such as unusual workload patterns or entropy, indicating potential security threats or inefficiencies.

ONTAP Autonomous Ransomware Protection (D): This feature within ONTAP automatically monitors and protects data by analyzing patterns that could indicate ransomware attacks. It detects abnormal changes in data patterns and acts to prevent potential ransomware from encrypting the data.

BlueXP backup and recovery (B)is focused on data protection and recovery rather than monitoring abnormal behavior.BlueXP operational resiliency (C)focuses on ensuring operational uptime and resilience but is not specifically targeted toward detecting abnormal activity or entropy.

When deployingNetApp Cloud Volumes ONTAPfor an Amazon Elastic Container Service (Amazon ECS) workload that involveslarge sequential I/O, the sizing characteristic to consider isMBps(megabytes per second). Large sequential I/O workloads, such as video streaming or backup operations, typically rely on high throughput rather than random IOPS.

Capacity (B)andIOPS (C)are important for other workload types, whileCPU (D)is less relevant for storage throughput requirements in this context.

When consolidating Microsoft Windows file servers into the cloud and centralizing SMB (Server Message Block) shares while preserving originalNTFS permissions, the appropriate NetApp technology isCloud Volumes Edge Cache. This solution provides centralized storage with local caching at the edge (branch offices), ensuring that SMB file shares are accessible with the original NTFS permissions intact. Cloud Volumes Edge Cache allows the company to move file shares to the cloud while still delivering high-performance access and maintaining file security models like NTFS.

BlueXP replication (A),FlexCache (C), andBlueXP copy and sync (D)provide replication, data caching, or synchronization capabilities but do not specifically address the preservation of NTFS permissions in a centralized cloud-based SMB file share environment.

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.
