Hitachi Vantara HQT-4420 Hitachi Vantara Qualified Professional - Content Platform Installation Exam Practice Test

Answer : A, B

After adding new nodes to an HCP G10 system, the following actions should be performed:

Upgrade the new nodes' software: Ensuring that the newly added nodes are running the same software version as the existing nodes is essential for compatibility and stability within the cluster.

Run the capacity balancing service: This service redistributes data across all nodes in the cluster to ensure balanced storage utilization and optimal performance, especially after the addition of new nodes.

These steps are necessary to maintain consistency, stability, and efficient use of resources within the HCP system after scaling up by adding new nodes.

Answer : A, D

When setting up the BIOS for an HCP G10, two key requirements are:

The BMC (Baseboard Management Controller) IP address, net mask, and gateway should be set: This configuration enables remote management and monitoring of the HCP G10 node, allowing administrators to manage the node even when the operating system is not running.

The OS virtual disk should be selected as the boot device: This ensures that the node boots from the correct storage device where the operating system is installed, which is essential for the system to operate correctly.

Hitachi Vantara Content Platform Installation Reference:

Proper configuration in the BIOS is critical for managing and booting the HCP G10 node effectively, as outlined in the installation instructions.

Answer : B

To configure an HCP S31 to its maximum capacity, the combination of 1 x 4U100 and 8 x 4U106 trays is used. The 4U100 is a 4U enclosure that can hold 100 drives, while the 4U106 is another 4U enclosure that holds 106 drives. This combination allows for the highest possible storage density and capacity, leveraging the different tray sizes to maximize the total available storage.

The configuration maximizes the storage capacity supported by the HCP S31 system, as specified in the installation and hardware configuration guidelines.

Answer : D

For a running HCP (Hitachi Content Platform) system to maintain quorum for cluster operations, a majority of nodes must be operational. Specifically, this means that at least 50% of the nodes + 1 node must be available to achieve quorum. Quorum is necessary to maintain consistency, availability, and coordination among the nodes in the cluster, ensuring that the cluster can continue operating correctly in case of node failures. This configuration avoids split-brain scenarios where multiple parts of the cluster operate independently.

Hitachi Vantara Content Platform Installation Reference:

The quorum requirement is designed to ensure that a majority of nodes are always participating in cluster operations, providing a safeguard against data corruption and ensuring high availability.

Answer : A, C

When performing a six-drive upgrade on an HCP G10 with local storage:

RAID level and Virtual Disks will be created automatically (A): This is correct. The system automatically handles the RAID configuration and creation of virtual disks to ensure that the new drives are correctly integrated into the existing storage structure.

The node is online during this procedure (C): This is also correct. The upgrade can be performed while the node remains online, minimizing disruption to the system's operation and ensuring continuous availability. These procedures are documented in the 'HCP G10 Maintenance and Upgrade Guide,' which outlines the steps for online upgrades and automatic RAID configuration.

Answer : C

To expand an existing HCP system consisting of four G10 nodes with additional G11 nodes, the minimum required HCP software version is Version 9.0 (C). This version introduces support for mixed-node environments, allowing the integration of different node generations (e.g., G10 and G11) within the same cluster. It is essential to ensure compatibility and seamless operation across the different node types. The 'HCP Software Release Notes for Version 9.0' provides detailed information on the support for mixed-node clusters.

Answer : C, D

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.
