1.Which two statements are correct regarding hardware upgrades on an HCP G10
system? (Choose two.)
A. Mixed clusters consisting of both G10 servers and CR servers are not allowed
B. Node additions are performed using the Configuration menu of the HCP setup
program
C. Upgrades can be performed online or offline
D. Data is automatically rebalanced after upgrade
Answer: C, D
Explanation:
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.

2.In the event of a SAN-attached G10 node failure, which LUN configuration will
maintain access to a given set of data LUNs?
A. Data Protection Level 2
B. HCP LUN replicator
C. Zero Copy Failover
D. Dynamic multi-pathing
Answer: D
Explanation:
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 SANattached 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
E

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

A. 1
B. 2
C. 3
D. 4
Answer: B
Explanation:
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."

5.You are installing an HCP G10 and are now setting the front-end connectivity. The
customer has provided you with IP addresses for their network for each node.
Which two actions should be performed on each node as part of the OS installation?
(Choose two.)
A. Set the BMC IP address
B. Set the NTP IP address(es)
C. Set the front-end IP address
D. Set the gateway IP address
Answer: A, C
Explanation:
When installing an HCP G10 and setting up front-end connectivity, two critical actions
must be performed on each node:
Set the BMC IP Address (A): The Baseboard Management Controller (BMC) IP
address must be set to allow for remote management and monitoring of each node.
This is crucial for out-of-band management, especially in large data center
environments where physical access to servers may be limited. Configuring the BMC
IP address is typically done during the initial setup of the operating system on the
HCP node.
Set the Front-End IP Address (C): The front-end IP address, which is used for client
network traffic, must be configured as provided by the customer. This IP address
allows each node to communicate with the client network, and it is a key part of the
configuration during OS installation.
These configurations are detailed in the "HCP G10 Network Configuration Guide" and
the "HCP G10 Installation and Configuration Manual," which provide step-by-step
procedures for setting up both the BMC and front-end IP addresses.

is a standard password used for initial access to the BIOS settings, allowing
administrators to configure the basic hardware settings of the HCP node.
BIOS Access:
The BIOS is the first layer of system settings that control how the hardware operates
before the system boots into the operating system or the HCP software. Accessing
the BIOS is usually necessary during the initial setup or hardware maintenance of
HCP nodes.
Security Considerations:
After initial setup, it is highly recommended to change the default BIOS password for
security reasons. Using default credentials like "hosyu95" can expose the system to
potential unauthorized access if left unchanged.
The default password is documented in the HCP G10 Installation Guides provided by
Hitachi Vantara, which emphasizes the importance of securing this access after
deployment.
