Question 5 Single choice

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.

A
TRUE
B
FALSE

Show answer and explanation

Correct answer: 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.

Question 6 Single choice

A bank customer purchases several Huawei flash storage devices to store upper-layer Oracle database service data. If an Oracle database fault occurs, engineers need to collect Oracle alert log files to locate the fault.

Which of the following commands cannot be used to query the alert log path?

A
ioscan -funC disk > /home/pvlinks_disk
B
CRS_HOME/bin/diagcollection.sh
C
show parameter background_dump_dest
D
db2support outpath -d db_name -c

Show answer and explanation

Correct answer: D

Explanation

The *HCIP-Storage V5.5 Training Material (Module 5: Storage System Maintenance and Troubleshooting)* addresses Oracle database troubleshooting: "To locate Oracle alert log files, commands like `show
parameter background_dump_dest' (SQL*Plus) and `CRS_HOME/bin/diagcollection.sh' (Oracle Grid Infrastructure) can query or collect log paths. The `ioscan -funC disk' command (HP-UX) lists disk devices,
which may indirectly help identify storage paths." However, "db2support outpath -d db_name - c" is specific to IBM DB2 databases, not Oracle, making it irrelevant for querying Oracle alert log paths. Thus, option D cannot be used.

Question 7 Single choice

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
TRUE
B
FALSE

Show answer and explanation

Correct answer: 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.

A
RPO is always zero.
B
RPO depends on the synchronization period and data change rate.
C
RPO equals the size of the dataset.
D
RPO does not apply to file or object data.

Show answer and explanation

Correct answer: B

Explanation

Asynchronous replication has a non-zero RPO determined by the sync cycle and data delta between cycles.

Question 9 Single choice

When delivering a Huawei OceanStor Pacific storage project, a Huawei engineer vigorously promoted the SmartEncryption feature of scale-out storage to customers.

Which of the following statements is false about this feature?

A
When the data is read using the DPC or NFS protocol, the SED obtains the identity authentication key from the key management server, reads and decrypts the ciphertext data, and then returns the plaintext data to the protocol layer. The protocol layer returns the plaintext data to client applications.
B
This feature supports encrypted data write using NFS, CIFS, HDFS, or S3. Data is decrypted and read
using NFS, CIFS, HDFS, or S3.
C
The file service client can write plaintext data through the NFS/CIFS/DPC protocol.
D
Huawei OceanStor Pacific series scale-out storage supports disk encryption. All data delivered by services is stored on self-encrypting disks (SEDs).

Show answer and explanation

Correct answer: C

Explanation

The SmartEncryption feature in Huawei OceanStor Pacific ensures data security. The *HCIP-Storage V5.5
Training Material (Module 3: Scale-Out Storage Technologies)* explains:
Option A: True. "For DPC or NFS reads, self-encrypting disks (SEDs) retrieve authentication keys from the key management server, decrypt ciphertext, and return plaintext to the protocol layer."
Option B: True. "SmartEncryption supports encrypted writes and decrypted reads via NFS, CIFS, HDFS, and S3 protocols."
Option C: False. "SmartEncryption encrypts data at the storage layer. Clients using NFS, CIFS, or DPC write data that is automatically encrypted by the system before storage, not written as plaintext."
Option D: True. "OceanStor Pacific uses SEDs for disk-level encryption, ensuring all service data is encrypted."

Question 10 Single choice

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?

A
Interrupted
B
Paused
C
Faulty
D
Migrating

Show answer and explanation

Correct answer: 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.
