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

Answer : C

The HCP back-end network is specifically designed to handle internal cluster traffic such as inter-node communication. This traffic type is critical for maintaining cluster synchronization, managing metadata, balancing loads, and ensuring consistent data storage and retrieval across the nodes in the cluster. Other types of traffic, like BMC access (A), tenant management console access (B), and replication traffic (D), typically occur over separate management or front-end networks. The 'HCP Network Configuration and Management Guide' provides detailed information on network segmentation and the roles of different network types in an HCP environment.

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 : A, C

For the HCP G10 SSD option:

Two SSD disks are installed at the rear of the server (A): This is correct. The SSDs in the HCP G10 server are typically installed at the rear of the server to provide fast access to critical system data, such as metadata and indexes.

Software RAID1 is used to mirror the disks (C): This statement is also correct. Software RAID1 provides mirroring of the SSD disks, ensuring redundancy and data protection in case of a disk failure. RAID1 is chosen for its simplicity and reliability in providing redundancy without requiring additional hardware. Details can be found in the 'HCP G10 Hardware Configuration and Maintenance Guide.'

Answer : C, D

Upgrades can be performed online or offline (C): Hitachi Vantara's HCP G10 system supports both online and offline upgrades, allowing administrators flexibility in how they choose to perform hardware upgrades. This capability ensures that the system can be updated with minimal disruption to operations. In an online upgrade, the system continues to run with full service availability, while an offline upgrade typically requires bringing the system down. This flexibility is critical for ensuring high availability and maintaining service level agreements.

Data is automatically rebalanced after upgrade (D): After a hardware upgrade, such as adding new nodes, HCP automatically rebalances the data across the cluster. This data rebalancing process is necessary to ensure that data is evenly distributed across all nodes, maintaining efficient storage utilization and performance. Rebalancing occurs as a background task without impacting the normal operation of the platform. HCP's intelligent data placement algorithms manage this process, ensuring optimized performance and data integrity.

These two statements accurately reflect how hardware upgrades and data management are handled in the HCP G10 system, as per Hitachi Vantara's architecture.

Answer : B

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.

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.
