NEW QUESTION # 63
In a flash storage system, the ports of the cascading interface module or onboard cascading ports on the controller enclosure can only connect to port P1 on the disk enclosure.
- A. TRUE
- B. FALSE
Answer: B
Explanation:
In Huawei flash storage systems, the ports of the cascading interface module or onboard cascading ports on the controller enclosure can connect to both P0 and P1 ports on the disk enclosure. These ports are used to establish communication between the controller enclosure and disk enclosures, facilitating data transfer and management. The specific port used for cascading can vary depending on the system configuration and design. Therefore, stating that they can only connect to P1 ports is incorrect.

NEW QUESTION # 71
The scale-out storage system supports cabinet-level security. That is, N data blocks and M parity blocks are stored in different cabinets. If M nodes or M disks are faulty, the system can still read and write data without service interruption or data loss. If M cabinets are faulty, services may be interrupted.
- A. FALSE
- B. TRUE
Answer: B
Explanation:
The statement describes the reliability mechanism of Huawei's scale-out storage systems, such as the OceanStor Pacific series, which employ cabinet-level security to enhance data availability. According to the
*HCIP-Storage V5.5 Training Material (Module 3: Scale-Out Storage Technologies)*, scale-out storage systems use distributed architectures with N data blocks and M parity blocks stored across different cabinets to ensure redundancy. This design leverages erasure coding (EC) or similar mechanisms to tolerate faults. The material explicitly states: "In a scale-out storage system, N+M redundancy ensures that if up to M nodes or M disks fail, the system can reconstruct data without interruption or loss. However, if M cabinets fail, the system may lose the ability to access sufficient parity or data blocks, potentially interrupting services." This confirms that the system can handle M node or disk failures without issue, but M cabinet failures may disrupt services due to the loss of distributed data or parity blocks. Therefore, the statement is true.

NEW QUESTION # 74
During the running of Huawei OceanStor Dorado series storage, a customer finds that the
"OutOfMemoryError" error is recorded in application logs and the FULL GC alarm is recorded in GC logs. Which of the following is not a cause for this performance issue?
- A. The memory value of the startup parameter is too small.
- B. Collection classes reference objects, which are not released after use. As a result, Java virtual machines (JVMs) cannot be reclaimed.
- C. An infinite loop exists in the code.
- D. There are too many threads and the context is switched too frequently.
Answer: D
Explanation:
Excessive threads and frequent context switching mainly cause CPU scheduling overhead and reduced runtime efficiency. They do not directly lead to heap exhaustion and repeated full garbage collection, which are more commonly caused by unreleased objects, insufficient JVM memory settings, or code defects such as infinite loops that continuously create objects.

NEW QUESTION # 76
In actual service scenarios, the HyperMetro feature of Huawei OceanStor Pacific series supports incremental synchronization. If a site fails, the site that wins arbitration continues providing services, and I/O requests change from the dual-write state to the single-write state. After the faulty site recovers, data generated during the fault can be synchronized to the recovered site.
- A. FALSE
- B. TRUE
Answer: B
Explanation:
The HyperMetro feature in Huawei OceanStor Pacific series provides active-active storage with high availability. The *HCIP-Storage V5.5 Training Material (Module 4: Storage Design and Implementation)* states: "HyperMetro supports incremental synchronization. In the event of a site failure, the site that wins arbitration (via quorum server or static priority) continues services in single-write mode. After the faulty site recovers, HyperMetro resumes dual-write mode and synchronizes incremental data generated during the fault to the recovered site, ensuring data consistency." This process ensures minimal data loss and seamless recovery, making the statement true. The material emphasizes that incremental synchronization reduces the bandwidth and time required compared to full synchronization.
