After a remote replication consistency group is created, if one remote replication task is faulty, other
tasks in the consistency group run normally without waiting for the faulty task to recover.
B
Explanation:
This question addresses the behavior of remote replication consistency groups in Huawei storage
systems, such as OceanStor Dorado or Pacific series. According to the *HCIP-Storage V5.5 Training
Material (Module 4: Storage Design and Implementation)*, a consistency group ensures that
multiple remote replication tasks operate as a single unit to maintain data consistency across LUNs or
volumes. The material states: “In a remote replication consistency group, if one replication task fails
(e.g., due to a link failure or configuration issue), the entire consistency group is affected, and other
tasks do not continue running normally. The system suspends all tasks in the group to preserve data
consistency until the faulty task is resolved or manually split.” This ensures that dependent data sets
remain synchronized. Therefore, the statement that other tasks run normally without waiting for the
faulty task is false, as the consistency group halts all tasks to maintain integrity.

Huawei OceanStor Pacific series storage systems support the _______ client access mode. This mode
allows a single client to connect to multiple storage nodes and supports MPI-I/O access. (Enter an
acronym.)
NFS
Explanation:
The question focuses on the client access modes supported by Huawei OceanStor Pacific series
storage systems, particularly for parallel access scenarios. The *HCIP-Storage V5.5 Training Material
(Module 3: Scale-Out Storage Technologies)* explains: “The OceanStor Pacific series supports the
NFS (Network File System) client access mode, which enables a single client to connect to multiple
storage nodes for parallel data access. This mode is optimized for high-performance computing (HPC)
workloads and supports MPI-I/O (Message Passing Interface Input/Output) for distributed
applications.” NFS allows clients to access file systems across multiple nodes, facilitating scalable and
parallel I/O operations, which aligns with the question’s description. The acronym “NFS” is the
correct answer.

The OceanStor Pacific series storage systems support the _______ feature. This feature uses the
classic token bucket algorithm to control the traffic upper limit. If local tokens are insufficient, tokens
are continuously generated and added to the token bucket based on the OPS and bandwidth upper
limit of the corresponding QoS control object as the rate.
Traffic
shaping
Explanation:
This question pertains to Quality of Service (QoS) features in Huawei OceanStor Pacific series storage
systems. The *HCIP-Storage V5.5 Training Material (Module 3: Scale-Out Storage Technologies)*
describes: “The OceanStor Pacific series supports the traffic shaping feature, which uses the classic
token bucket algorithm to control the upper limit of traffic. When tokens in the bucket are
insufficient, the system generates and adds tokens based on the operations per second (OPS) and
bandwidth limits defined for the QoS control object.” Traffic shaping regulates data flow to prevent
network congestion and ensure fair resource allocation, making it the correct feature name for this
description.

A government customer has purchased several Huawei OceanStor Dorado 18000 series storage
devices for service deployment, and an engineer needs to create storage pools on the storage
system. However, before doing so, the engineer must configure LUNs and LUN groups, and create the
mapping between the LUN groups and host groups.
B
Explanation:
The question addresses the configuration process for storage pools in Huawei OceanStor Dorado
18000 series systems. The *HCIP-Storage V5.5 Training Material (Module 4: Storage Design and
Implementation)* clarifies: “To create storage pools, an engineer configures the physical disks or disk
domains, which serve as the foundation for storage resources. LUNs and LUN groups are created
after the storage pool is established, as LUNs are logical divisions of the pool’s capacity. Mapping
LUN groups to host groups is a subsequent step to enable host access.” The statement in the
question incorrectly suggests that LUNs, LUN groups, and mappings must be configured before
creating storage pools, which reverses the actual process. Storage pools are a prerequisite for LUN
creation, not the other way around, making the statement false.

An industry customer has purchased a Huawei OceanStor Pacific 9950 scale-out storage device for
service deployment. During an inspection of the device, the location indicator of a main storage disk
module is steady yellow. What is the status of the disk module?
D
Explanation:
This question tests knowledge of disk status indicators in Huawei OceanStor Pacific 9950 systems.
The *HCIP-Storage V5.5 Training Material (Module 5: Storage System Maintenance and
Troubleshooting)* provides details on disk module indicators: “A steady yellow location indicator on
a main storage disk module indicates that the disk is faulty or about to fail. This status signals that
the disk requires attention, such as replacement, to prevent data loss or service disruption.” The
material further clarifies the following for other options:
- Option A: Incorrect. A blinking yellow indicator, not a steady one, typically indicates that the disk is
being located (e.g., via DeviceManager or CLI).
- Option B: Incorrect. A steady green indicator signifies that the disk is running properly.
- Option C: Incorrect. A powered-off disk would have no indicator light or a specific power-off signal,
not a steady yellow light.
Thus, option D accurately describes the disk’s status.

When delivering a flash storage project, Huawei engineers introduced the arbitration mechanism of
HyperMetro to the customer. Which of the following statements is false about the arbitration
modes?
C
Explanation:
The HyperMetro feature in Huawei storage systems, such as OceanStor Dorado, provides active-
active data access with arbitration mechanisms to handle site failures. The *HCIP-Storage V5.5
Training Material (Module 4: Storage Design and Implementation)* details HyperMetro arbitration
modes:
- Option A: True. The material states: “In the absence of a quorum server, HyperMetro operates in
static priority mode, where the preferred site is designated to win arbitration and continue services
during a failure.”
- Option B: True. The material explains: “In static priority mode, if the preferred site fails, the non-
preferred site does not automatically take over to avoid split-brain scenarios. Services stop, and
manual intervention is required to forcibly start services on the non-preferred site.”
- Option C: False. The material clarifies: “In quorum server mode, the quorum server can be
deployed on physical machines or virtual machines, provided it meets the performance and network
requirements.” This makes the statement that it can only be deployed on physical machines
incorrect.
- Option D: True. The material confirms: “In quorum server mode, if the link between storage
systems fails, both systems send arbitration requests to the quorum server to determine which site
continues providing services.”
Thus, option C is false.

An industry customer has purchased several Huawei flash storage devices for service deployment. An
engineer wants to configure the HyperSnap feature on the storage devices. However, during the
configuration, the engineer discovers that snapshots cannot be created for an existing protection
group. The possible cause is that the storage pool where the source LUNs in the protection group
reside has no available capacity.
A
Explanation:
The HyperSnap feature in Huawei flash storage systems, such as OceanStor Dorado, enables point-in-
time snapshots for data protection. The *HCIP-Storage V5.5 Training Material (Module 2: Flash
Storage Technologies)* states: “To create snapshots using HyperSnap, the storage pool containing
the source LUNs must have sufficient available capacity to store snapshot metadata and copy-on-
write (COW) data. If the storage pool lacks free space, snapshot creation for a protection group will
fail.” This aligns with the question’s statement that a lack of available capacity in the storage pool
prevents snapshot creation for a protection group, making the statement true. The material
emphasizes that capacity issues are a common cause of snapshot failures, as snapshots require
additional space for incremental changes.

An industry customer has purchased a Huawei OceanStor Pacific scale-out storage system for service
deployment. An engineer configures NFS file sharing on the storage system through NFSv4.0. Which
of the following commands can the engineer use to switch the user view to the developer view on
the command line interface (CLI)?
C
Explanation:
This question focuses on CLI operations for Huawei OceanStor Pacific scale-out storage systems. The
*HCIP-Storage V5.5 Training Material (Module 3: Scale-Out Storage Technologies)* provides
guidance on CLI access modes: “To switch from the user view to the developer view on the CLI for
OceanStor Pacific systems, the command ‘change user_mode current_mode user_mode=developer’
is used. This command elevates the user’s privilege level to access advanced configuration and
debugging options.” Let’s evaluate the options:
- Option A: Incorrect. The command `change domain ad_manager` relates to Active Directory
management, not view switching.
- Option B: Incorrect. The command `change dns general` configures DNS settings, not user modes.
- Option C: Correct, as it matches the documented command for switching to developer view.
- Option D: Incorrect. The command `change nas_Idap` configures LDAP settings for NAS services, not
CLI view modes.
Thus, option C is the correct command.

An industry customer purchased several Huawei OceanStor Pacific series scale-out storage devices
for service deployment, and an engineer configured the SmartMigration feature on the storage
devices. Now the engineer wants to change the split mode and migration rate of a SmartMigration
task due to changes in service requirements. Which of the following SmartMigration running statuses
does not allow the engineer to perform the change?
C
Explanation:
The SmartMigration feature in Huawei OceanStor Pacific enables data migration between storage
resources. The *HCIP-Storage V5.5 Training Material (Module 4: Storage Design and
Implementation)* explains: “The split mode and migration rate of a SmartMigration task can be
modified only when the task is in certain statuses, such as Interrupted, Paused, or Faulty. When the
task is in the Migrating status, changes to split mode or migration rate are not allowed, as the system
is actively transferring data.” This is because modifying parameters during active migration could
disrupt the process or cause data inconsistency. Let’s evaluate:
- Option A: Interrupted allows changes, as the task is stopped.
- Option B: Paused allows changes, as the task is temporarily halted.
- Option C: Faulty allows changes, as the task is not actively running.
- Option D: Migrating does not allow changes, as the task is in progress.
Thus, option D is the status that prevents changes.

A government customer has purchased several Huawei OceanStor Pacific series storage devices. An
engineer wants to install the distributed parallel client (DPC) on the storage devices. The operations
before DPC installation have been completed. Now, the engineer needs to add DPC nodes. Which of
the following statements are true about adding nodes?
B, D
Explanation:
This question addresses the process of adding DPC nodes in Huawei OceanStor Pacific systems. The
*HCIP-Storage V5.5 Training Material (Module 3: Scale-Out Storage Technologies)* states: “To add
DPC nodes, engineers can use DeviceManager to either manually add nodes by entering the
management IP address or batch import nodes using a template. For manual addition, the
management IP address is required to establish communication with the node. For batch import, a
template must be downloaded, filled with node details, and uploaded to complete the process.
Authentication is required in both modes to ensure secure node addition.” Let’s evaluate:
- Option A: False. Authentication is required for both manual and batch methods to validate node
addition.
- Option B: True. The material confirms that the management IP address is required for manual node
addition.
- Option C: False. The service IP address is not used for node addition; the management IP is needed.
- Option D: True. The material describes the batch import process as requiring a filled template
upload.
Thus, options B and D are true.
