The _____ feature provided by the OceanStor Pacific series storage system supports OPS and bandwidth upper limit control based on namespaces, accounts, and client IP addresses.
Answer : A
The correct answer isSmartQoS. Huawei's OceanStor Pacific documentation states thatSmartQoS supports OPS and bandwidth upper limit control by namespace, account, and client IP address. This matches the question exactly.
Question 2
A financial customer purchased a Huawei flash storage system for service deployment. An engineer configured the HyperClone feature on the storage system. If the running status of a clone consistency group (CG) is "DiffCopy reverse syncing" or "Unsynchronized", the engineer cannot delete the clone CG.
Answer : B
This statement isfalse. Huawei's HyperClone documentation fordeleting a clone CGstates that the prerequisites include:
That means a clone CGcan be deleted when its running status is 'Unsynchronized'. Since the question says the engineercannotdelete the clone CG if the status is'DiffCopy reverse syncing' or 'Unsynchronized', the whole statement is incorrect becauseUnsynchronizedis actually an allowed deletion status.

Question 3
Routine management on Huawei flash storage systems involves power-on and power-off. Which of the following statements is false about power-on and power-off?
Answer : C
The *HCIP-Storage V5.5 Training Material (Module 5: Storage System Maintenance and Troubleshooting)* covers power management:
- Option A: True. ''Correct expansion cable connections are required before power-on to ensure proper operation.''
- Option B: True. ''The BMC system allows powering on controller enclosures via the external management IP when none are powered on.''
- Option C: False. ''After an emergency power-off, the storage system is powered on via DeviceManager, CLI, or BMC, not by pressing the controller enclosure's power button, which is used for normal power-on.''
- Option D: True. ''In OceanStor Dorado 8000, powering on a controller enclosure automatically powers on cascaded disk enclosures.''
Thus, option C is false.

Question 4
Assume a government office purchases a Huawel OceanStor Pacific 9550 storage device. During an Inspection, an engineer notices the IAN on motherboard (LOM) optical port Indicator on the rear panel of the device Is steady yellow. This indicates that data is being transmitted at a rate of 25 Gbit/s.
Answer : B
Question 5
Huawei flash storage supports HyperReplication, which is mainly used in data disaster recovery and backup scenarios. Which of the following statements are true about this feature?
Answer : B, C, D
A is false.Huawei definessecondary resource protectionas controlling theaccess status of the secondary resource. For example, the secondary volume/file system can be set toread-onlyorread/write, or in Pacific documentation, the secondary namespace does not receive host read/write services and only receives replication data. It doesnotmean suspending the replication relationship.
B is true.Huawei defines apairas the data replication relationship between theprimary and secondary LUNs/volumes. Huawei documentation also states that when the running status isNormal, data at the two sites has been synchronized successfully.
C is true.Huawei explicitly states that aconsistency groupisa collection of pairs that have a service relationship with each other.
D is true.Huawei describessynchronizationas the process of synchronizing or copying data from theprimary resource/volume to the secondary resource/volume
Question 6
An engineer configures the HyperClone feature on a Huawei OceanStor Dorado 3000 storage system. The secondary LUN is configured with 20 GB and the primary LUN with 10 GB. In this case, reverse synchronization can be implemented. During the reverse synchronization, the capacity of the primary LUN cannot be expanded.
Answer : A
This statement is true. Huawei's HyperClone documentation states that reverse synchronization is supported only when the secondary LUN capacity is greater than or equal to the primary LUN capacity. In this question, the secondary LUN is 20 GB and the primary LUN is 10 GB, so the capacity condition for reverse synchronization is met.
Huawei also states that during reverse synchronization, the capacity of the primary LUN cannot be expanded. This directly matches the second part of the statement.
Question 7
When deploying a Huawei converged storage system, engineer A uses the UltraPath software. Which of the following statements are false about the load balancing algorithms of UltraPath?
