Question # 10

Huawel OceanStor Pacific series products provide object storage capabilities and support cross-site disaster recovery (DR). Which of the following statements about object storage cross-site DR is false?

In cross-site DR cluster deployment mode, each site is independent. Specifically, it has an independent DeviceManager GUI and independent erasure code (EC) configuration.

In backup and archiving scenarios that do not require a low latency, the redundancy mode between sites can be set to EC redundancy during cross site DR configuration.

During cross-site DR configuration, if replicas are used for redundancy protection across sites, each site has complete object data.

The cross-site DR of OceanStor Pacific series uses an asynchronous replication mechanism. The recovery point objective (RPO) is greater than 0, and the traffic control configuration cannot be adjusted.

Question # 12

If a performance Issue occurs in Huawei flash storage, an engineer can perform optimization operations according to the storage performance optimization process. Which of the following statements is false about the performance optimization process?

In the information collection phase, the engineer needs to collect basic information about applications and data, such as the impact of application configurations on data, data size, and read/write ratio.

In the test and application phase, the engineer needs to test the configurations to check whether the optimization objective is achieved. If yes, the engineer can put the system into use.

In the optimization analysis phase, the engineer needs to specify the performance optimization objective, find out the performance bottleneck, and identify the parts that play a key role in Improving the system performance.

In the optimization operation phase, the engineer needs to deploy DR for the service system, and needs to modify multiple configuration at a time during the optimization configuration.

Question # 13

When delivering a Huawel OceanStor Pacific scale-out storage project, an engineer introduced the end-to-end data Integrity check technology of scale-out storage to the customer. Which of the following statements are false about this technology?

This technology enables the storage system to implement periodic background data integrity check. When the service load is heavy or service access is frequent, the system automatically starts periodic background data integrity check and self-healing.

For silent data scenarios such as bit change and read offset, the end-to-end data integrity check technology supports logical block addressing (LBA) check of clusters and hosts.

Block, NAS, and object services support end-to-end data integrity check, but the HDF5 service does not.

In this technology, write requests are checked at the system entry (virtual block service). User data is checked again in the object storage device (OSD) before being written to disks. Data Is written to disks only after the data integrity check succeeds.

Question # 16

Assume an industry customer purchased several Huawei flash storage devices for service deployment. During routine management, an engineer found that the host bus adapter (HBA) driver version of the host is outdated and the number of concurrent HBAs was insufficient. As a result, the latency on the host differs greatly from that on the storage side. Which of the following measures can the engineer take to optimize performance?

Use the management software provided by the HBA vendor to query and modify the number of concurrent HBAs.

Upgrade the HBA driver to the latest version.

Change the load balancing algorithm of the multipathing software to min-task.

Change the cache prefetch policy to constant prefetch.
