Hitachi Vantara HQT-4420 Exam Actual Questions

Before re-installing the S10 node for production:

The S10 node must be retired in the HCP G10 System Management Console: This step ensures the S10 node is correctly removed from the cluster management to avoid conflicts during re-installation.

The S10 node must be disconnected from the HCP G10 cluster: Disconnecting the node from the cluster prevents any unintended interactions with the current configuration.

The S10 node must boot the installation package from the USB drive: This is required to load the new installation environment onto the S10 node, ensuring a clean and fresh installation.

Hitachi Vantara Content Platform Installation Reference:

These steps are necessary to prepare the S10 node for reinstallation without causing disruptions to the existing HCP G10 cluster operations.

If the pre-upgrade check procedure fails due to insufficient capacity on node 103 to perform the upgrade, the service procedure to run is Free Space On Nodes. This procedure helps to identify and clear unnecessary files or redistribute data, freeing up the required capacity on the node to proceed with the upgrade.

Hitachi Vantara Content Platform Installation Reference:

The 'Free Space On Nodes' procedure is specifically designed to manage and optimize storage capacity across HCP nodes, ensuring that upgrades and other operations have adequate space to execute successfully.

The maximum number of drives supported in one HCP S10 enclosure is 60. The S10 enclosure is designed to accommodate a large number of drives to provide significant storage capacity in a relatively compact form factor. This drive density is essential for scaling storage in environments that require large data volumes. This configuration is detailed in the 'HCP S10 Hardware Configuration Guide,' which outlines the specifications and capacities of the S10 enclosures.

The most cost-effective solution for a customer requiring 2 PB of usable capacity is HCP G10 with local storage and one S30 node (B). This configuration leverages the local storage of the G10 along with the large storage capacity provided by the S30 node, which is optimized for large-scale, cost-effective storage. The S30 node can store a significant amount of data, making it a suitable choice for achieving the required capacity with fewer nodes, reducing costs. The 'HCP G10 and S30 Configuration and Sizing Guide' provides more details on cost-effective configurations for various capacity requirements.

You must run the install program as root (C): To enable encryption for data at rest on an HCP system, the installation program must be executed with root privileges. Running the installation as root ensures that the program has the necessary permissions to configure encryption settings and other critical system operations, such as accessing low-level disk management functions and securing data at rest.

Once enabled, encryption cannot be disabled (D): In the HCP system, once encryption is enabled for data at rest, it cannot be disabled. This is a security feature designed to ensure that sensitive data remains protected throughout its lifecycle on the platform. Disabling encryption after it has been enabled would pose significant security risks, hence the system is designed to prevent this action to maintain data integrity and security.

Other options, like the encryption key being displayed several times during installation (A) or the use of SSH to enable encryption (B), are not applicable to the HCP installation and encryption process. The encryption key is carefully protected, and SSH is not specifically required for enabling encryption.
