- D. minimum 50% of the nodes + 1 node
Answer: D
Explanation:
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.
NEW QUESTION # 14
Which two statements are true about encryption for data at rest on an HCP system? (Choose two.)
- A. SSH connection must be used to enable encryption during the installation process.
- B. You must run the install program as root.
- C. Once enabled, encryption cannot be disabled.
- D. The encryption key is displayed several times during the installation process.
Answer: B,C
Explanation:
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.
