問題 #13
Which two statements are correct regarding hardware upgrades on an HCP G10 system? (Choose two.)
答案:A,C
解題說明:
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.

問題 #14
You are installing a HCP G10 with attached storage. The system will be networked using four 10 GbE SFP+ interfaces.
How many PCIe cards are installed in each HCP G10 node?
答案:B
解題說明:
Each HCP G10 node with attached storage and networked using four 10 GbE SFP+ interfaces requires two PCIe cards. Typically, one PCIe card is allocated for network connectivity, while the other is used for storage connectivity. The cards need to support the necessary number of network interfaces and any additional connections required for attached storage. The specific configuration depends on the HCP model, but generally, two PCIe cards are sufficient to handle both networking and storage interfaces as described in the "HCP G10 Hardware Installation Guide."
問題 #15
What is the default password for logging into the S10 or the S30 management console?
答案:D
解題說明:
The default password for logging into the S10 or the S30 management console is "Chang3Me!". This default password is provided to ensure initial access to the management console, but it is strongly recommended to change this password immediately upon first login to maintain system security. Information regarding default credentials can be found in the "Hitachi Vantara HCP S10 and S30 Management Console User Guide."
問題 #16
In the event of a SAN-attached G10 node failure, which LUN configuration will maintain access to a given set of data LUNs?
答案:D
解題說明:
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
問題 #17
How should the RAID group(s) and logical volume(s) be configured on an HCP G10 node with six internal drives?
答案:A
解題說明:
On an HCP G10 node with six internal drives, the recommended configuration is to create a single RAID group with a single logical volume. This setup maximizes the available storage capacity and provides a balanced approach to data protection, performance, and management simplicity. By using a single RAID group, the HCP system can efficiently manage data redundancy and integrity across all drives.
Hitachi Vantara Content Platform Installation Reference:
Configuring a single RAID group with a single logical volume simplifies management and provides optimal performance and redundancy, which aligns with the best practices for setting up an HCP G10 node.
