Question No. 1

A customer is using a four-node HCP G10 cluster and they would like to upgrade to eight nodes.

Which two node models can be used to upgrade the cluster? (Choose two.)

Show Answer Hide Answer
Correct Answer: B, C

To upgrade a four-node HCP G10 cluster to an eight-node cluster, the customer can use additional G10 or G11 node models. The HCP platform supports the addition of both G10 and G11 nodes in the same cluster, as they are compatible with each other in terms of architecture, management, and functionality. This allows the cluster to be scaled up by adding more nodes of either model to meet growing storage and performance needs.

Hitachi Vantara Content Platform Installation Reference:

When expanding an HCP G10 cluster, it is crucial to use node models that are supported and compatible with the existing cluster configuration, such as G10 and G11.


Question No. 2

Which two ports on an HCP G10 node are used for back-end network connection"? (Choose two.)

Show Answer Hide Answer
Correct Answer: C, D

The HCP G10 nodes use eth2 and eth3 ports for back-end network connections. These ports are configured for communication between the nodes and storage or within the HCP cluster itself. Back-end networks typically handle internal data traffic, replication, and synchronization, and therefore use specific dedicated ports to ensure optimal performance and separation from front-end client traffic.

Hitachi Vantara Content Platform Installation Reference:

The back-end network is crucial for internal HCP operations, and using eth2 and eth3 aligns with standard configurations as defined in the installation guidelines for maintaining proper data flow and redundancy.


Question No. 3

Which two statements are correct regarding hardware upgrades on an HCP G10 system? (Choose two.)

Show Answer Hide Answer
Correct 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.

Question No. 4

Which two VMware deployment packages are supported by HCP systems running v7.2 or later? (Choose two.)

Show Answer Hide Answer
Correct Answer: A, C

For HCP systems running version 7.2 or later, the supported VMware deployment packages are:

HCP VMware edition: This is a full-featured deployment package designed for use in production environments. It provides all the necessary components for running HCP in a VMware virtualized environment.

HCP VMware evaluation edition: This is a version meant for evaluation purposes, allowing potential users or administrators to test and familiarize themselves with HCP's capabilities in a non-production environment.

Hitachi Vantara Content Platform Installation Reference:

Both the 'VMware edition' and 'evaluation edition' are designed to be compatible with HCP version 7.2 or later, with the former being a fully supported production deployment package, while the latter is for trial or evaluation.


Question No. 5

After adding new nodes to an HCP G10 system, which two actions should be performed? (Choose two.)

Show Answer Hide Answer
Correct 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.

Hitachi Vantara Content Platform Installation Reference:

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