NetApp Certified Hybrid Cloud Administrator Professional NS0-304 Exam Practice Test

Answer : D

When setting up NetApp Cloud Tiering with an S3 object storage bucket, it is crucial that the bucket configuration adheres to the default IAM policy for the cloud connector. Here's the configuration requirement:

Bucket Configuration with Specific Prefix: The IAM policy often specifies access permissions based on resource names or prefixes. For Cloud Tiering, particularly when integrating with FabricPool technology, the bucket should have a prefix set to fabric-pool. This allows the Cloud Tiering service to correctly identify and interact with the bucket, ensuring compliance with security policies and access controls.

Verify IAM Policy Configuration: Ensure that the IAM policy for the cloud connector includes permissions for operations on the S3 bucket with the fabric-pool prefix. This typically includes permissions to put, get, list, and delete objects within the bucket.

For further information on configuring S3 buckets for NetApp Cloud Tiering and detailed IAM policy settings, please consult the NetApp Cloud Tiering documentation available on the NetApp website: NetApp Cloud Tiering Documentation.

Answer : C

When adding a new AFF A250 to an existing 4-node cluster with cloud tiering enabled to AWS, a minimum of two logical interface (LIF) configurations are necessary for the tiering process. Here's the rationale:

LIF Configuration for Cloud Tiering: Each node in a NetApp cluster typically requires a minimum of one data LIF for client access and an additional LIF for inter-cluster communication. However, for cloud tiering purposes specifically, at least one data LIF per node is essential to manage the data movement to and from AWS.

Purpose of Additional LIFs: Since the AFF A250 is being added to an existing cluster, it will share the cluster's existing infrastructure but will still need its data LIFs configured to participate in cloud tiering.

Best Practices: It's advisable to configure multiple LIFs across different subnets or network paths to ensure redundancy and optimal data flow, especially in a cloud-tiered environment to maintain performance and availability.

For more specific instructions on configuring LIFs for cloud tiering in a NetApp environment, refer to NetApp's technical documentation on cloud tiering and cluster networking: NetApp Cloud Tiering Documentation.

Answer : C

In the scenario where an administrator is using BlueXP Copy and Sync to move an NFS dataset and the Data Broker shows the status 'Unknown' despite confirmed NFS connectivity, the required network service is HTTPS. Here's why:

HTTPS for Data Broker Communication: The Data Broker, which orchestrates data movement in BlueXP Copy and Sync, uses HTTPS to communicate securely with both the source and destination systems, as well as with NetApp's cloud services. This secure communication channel is essential for managing the data transfer processes reliably and securely.

Verifying HTTPS Connectivity: Ensure that all network components, such as firewalls and routers, are configured to allow HTTPS traffic (port 443) from the Data Broker to the NFS endpoints and back. This includes checking for any blocked ports or filtered traffic that could impede the Data Broker's operation.

Troubleshooting Network Issues: If the status remains 'Unknown,' further network diagnostics may be necessary to identify any disruptions or misconfigurations in HTTPS connectivity that could affect the Data Broker's functionality.

For more detailed troubleshooting steps and configuration tips, please refer to the NetApp BlueXP documentation, focusing on the network requirements for Data Broker: NetApp Data Broker Documentation.

Answer : A

For provisioning block storage on an AWS FSx for NetApp ONTAP instance for a Linux server, the most suitable protocol is iSCSI. Here's why:

iSCSI Compatibility: iSCSI is widely supported across various operating systems, including Linux, and is ideal for provisioning block storage. It allows the Linux server to access storage volumes over a TCP/IP network, simulating local block storage.

Configuration Steps: To set this up, configure the FSx for NetApp ONTAP instance to provide iSCSI LUNs (Logical Unit Numbers). This involves creating an iSCSI target and associating it with the LUNs that the Linux server will access.

Connect from Linux Server: On the Linux server, set up the iSCSI initiator to connect to the iSCSI target on the FSx instance. This usually involves installing iSCSI utilities and configuring the initiator to establish and maintain the iSCSI session.

For a comprehensive guide on setting up iSCSI with FSx for NetApp ONTAP and Linux, please refer to the AWS documentation: AWS FSx for NetApp ONTAP Documentation.

Answer : A

When deploying a FlexCache volume in Cloud Volumes ONTAP, and the origin volume is located in an on-premises cluster, the network used is the InterCluster network. This network type is designed specifically for communications between different ONTAP clusters, which is essential for operations such as data replication and FlexCache functionality. The InterCluster network facilitates the seamless interaction between the on-premises cluster (where the origin volume resides) and the Cloud Volumes ONTAP instance in the cloud (where the FlexCache volume is being deployed). Node Management and Cluster Management networks are used for management operations and not for data transfer between clusters. IntraCluster is used within a single cluster for communication between nodes. For further details, you can review the NetApp documentation on FlexCache configurations and the use of InterCluster networks in ONTAP data management, which explains how these networks enable efficient data replication across clusters.

Answer : A

To move several volumes containing iSCSI LUNs from an ONTAP AFF cluster to Cloud Volumes ONTAP (CVO), the most appropriate method is using SnapMirror. Here's the process:

Utilizing SnapMirror for LUN Migration: SnapMirror is NetApp's replication technology that is ideally suited for efficiently transferring data between ONTAP systems, including from AFF to CVO. It is capable of handling complex data structures like iSCSI LUNs, ensuring data integrity and consistency during the transfer.

Configuration of SnapMirror: Set up a SnapMirror relationship between the source AFF cluster and the destination CVO instance. This involves configuring the SnapMirror policy, scheduling the replication, and initializing the transfer of data.

Advantages for iSCSI LUNs: SnapMirror maintains the layout and attributes of the iSCSI LUNs during replication, which is crucial for ensuring that the storage is ready for immediate use upon completion of the replication to the CVO environment.

For step-by-step instructions on configuring and using SnapMirror for transferring iSCSI LUNs, consult the NetApp documentation on SnapMirror: NetApp SnapMirror Documentation.

Answer : C

When deploying FlexCache volumes between a Production SVM (Storage Virtual Machine) and a Development SVM on the same 8-node cluster, the network being used is the IntraCluster network. Here's why:

Role of IntraCluster Network: The IntraCluster network is specifically designed for communication within the same cluster. This network is used for operations such as data replication and data movement between different SVMs within the same physical cluster.

Purpose of FlexCache Volumes: FlexCache volumes are typically used to provide fast, localized access to data by caching it closer to where it is being accessed. In the scenario where both SVMs are within the same cluster, the IntraCluster network facilitates the necessary data transfers to establish and manage these FlexCache volumes effectively.

Optimization and Efficiency: Utilizing the IntraCluster network for this purpose ensures high-speed connectivity and reduces latency, which is crucial for maintaining performance and efficiency in operations involving multiple SVMs within the same cluster.

For additional information on FlexCache and network configurations in NetApp systems, refer to the NetApp documentation on FlexCache and cluster networking: NetApp FlexCache Documentation.
