OLTP is a major application in a traditional relational database and mainly used to process basic and routine transactions. Which of the following statements is false about OLTP?
- A. In the OLTP service, the back-end port bandwidth does not need to be monitored.
- B. In the OLTP service, special attention is usually required for the average I/O response time and average CPU usage of controllers.

- D. From the database perspective, reading, writing, and changing of each transaction involve a small amount of data, and access requests from many users are processed simultaneously.
Answer: A
Explanation:
In OLTP services, back-end port bandwidth is critical and must be monitored to ensure sufficient data throughput and avoid bottlenecks. Therefore, the statement that back-end port bandwidth does not need monitoring is false.

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.
- A. TRUE
- B. FALSE
Answer: B
Explanation:
In a remote replication consistency group, all replication tasks are managed as a consistency unit. If one replication task becomes faulty, the other tasks in the group will not continue independently; they are affected to maintain data consistency across the group.

NEW QUESTION # 145
A company has purchased multiple Huawei OceanStor Pacific devices to deploy the remote replication service. During routine operation and maintenance, an administrator needs to manage the replication cluster. Which of the following statements are true about a replication cluster?
(Choose all that apply.)
- A. The name of a replication cluster for which cross-site disaster recovery is enabled cannot be changed, but the replication cluster can be deleted.
- B. When the capacity of a replication cluster is expanded, the replication network can share the same subnet with other networks.
- C. Capacity reduction of a replication cluster can be performed only when the number of nodes is greater than or equal to 4.
- D. When an IP address of a replication cluster is changed, if a node in the replication cluster uses multiple ports and different replication ports are configured with IP addresses in the same network segment, the original policy-based route must be deleted before configuring a new policy-based route.
Answer: C,D
Explanation:
The capacity of a replication cluster can only be reduced by removing at least four nodes at a time. When changing the cluster's IP address and a node has multiple replication ports configured with IPs in the same subnet, you must delete the original policy-based route before adding the new one.

NEW QUESTION # 154
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
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.

HCIP-Storage V5.5 Training Material, Module 4: Storage Design and Implementation, Section 4.2:

Huawei scale-out storage provides file services using the distributed parallel client (DPC) to meet the requirements of high performance computing (HPC) scenarios. Which of the following statements about the DPC is false?
- A. A single client can connect to multiple storage nodes, and the single-stream bandwidth is high.
- B. DPC provides high storage performance for HPC scenarios.
- C. DPC does not support MPI-I/0. Therefore, DPC can provide better access performance for upper- layer services.
- D. DPC implements I/O-level load balancing, preventing service load forwarding between storage nodes.
Answer: C
Explanation:
DPC supports MPI-IO, which is essential for HPC scenarios to achieve high-performance parallel access. The statement claiming it does not support MPI-IO is incorrect.
