Authentic Hitachi Certification Exam HQT-4420 Questions Answers

The Data At Rest Encryption (DARE) feature can only be enabled during the initial cluster configuration. This is because DARE involves setting encryption parameters and keys that must be applied uniformly across all nodes in the cluster from the very beginning. Enabling DARE post-deployment could result in inconsistent encryption states and potential data access issues. The "HCP Security and Encryption Configuration Guide" details the process for enabling DARE and emphasizes the need for configuring it at the cluster's initial setup phase.

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.

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

To configure host group security on a new HCP G10 with attached storage, the World Wide Port Name (WWPN) is required. The WWPN is a unique identifier for each Fibre Channel port in a storage area network (SAN) environment. It is used to configure access control and define which hosts can communicate with specific storage resources. This setting ensures that only authorized hosts can access the storage, enhancing the overall security of the HCP system. This requirement is documented in the "Hitachi Vantara HCP G10 Storage Configuration Guide."
