Hitachi Vantara HQT-4420 Exam Questions

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.'

When replacing an entire HCP G10 node, it is necessary to check the BIOS configuration. This ensures that the new hardware is correctly configured according to the required specifications for the HCP system. The BIOS settings need to be consistent with the rest of the cluster nodes to ensure proper functionality, performance optimization, and hardware compatibility. This check might include verifying boot order, enabling virtualization, setting appropriate hardware clock configurations, and other critical settings outlined in the 'Hitachi Vantara HCP G10 Installation and Configuration Guide.'

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.

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.

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.
