Which two statements are true about encryption for data at rest on an HCP system? (Choose two.)
- A. You must run the install program as root.
- B. The encryption key is displayed several times during the installation process.
- C. Once enabled, encryption cannot be disabled.
- D. SSH connection must be used to enable encryption during the installation process.
正解：A、C
解説：
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.

In the event of a SAN-attached G10 node failure, which LUN configuration will maintain access to a given set of data LUNs?
- A. Dynamic multi-pathing
- B. HCP LUN replicator
- C. Zero Copy Failover
- D. Data Protection Level 2
正解：A
解説：
Dynamic Multi-Pathing (DMP) is a method that ensures continuous access to data in the event of a node failure or path failure within a SAN environment. When a SAN-attached G10 node in a Hitachi Content Platform (HCP) fails, DMP allows for automatic rerouting of data traffic to an alternate path without interruption. This is accomplished by creating multiple physical paths between the storage devices and the servers, ensuring that if one path fails, another can be utilized, thereby maintaining access to data LUNs.
Hitachi Vantara Content Platform Installation Reference:
Dynamic Multi-Pathing (DMP): In the context of HCP, DMP is critical for high availability and fault tolerance. It enables redundancy in connectivity between nodes and storage arrays, ensuring continuous data access and minimal service disruption in the event of hardware failure. This technology is designed to work in SAN environments where multiple paths are configured between storage and compute resources.
SAN-Attached G10 Node Failure: If a G10 node experiences failure, DMP comes into play by dynamically redirecting I/O operations from the failed path to an alternative path, ensuring uninterrupted access to data stored in the associated LUNs.
By using DMP, the system effectively prevents data loss or access interruption, which is why this configuration is recommended for maintaining LUN access during node failures in a SAN-attached HCP environment
