Questions # 3:

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?

Options:

A.

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.


B.

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.


C.

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


D.

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.

Options:

A.

TRUE


B.

FALSE

Questions # 6:

When delivering a Huawel OceanStor Pacific scale-out storage project, Huawei engineers Introduced the end-to-end load balancing capabllty supported by the scale-out storage to the customer. Which of the following statements are false about the load balancing capability?

Options:

A.

The route-based hash policy of the persistence layer is different from that of the service layer. The route-based hash policy of the persistence layer is implemented based on weights, while that of the service layer is implemented based on STORE DHT.


B.

Unstructured and structured services at the service layer have different route-based hash policies. However, both unstructured and structured services are mapped based on the same basic routing model.


C.

In load balancing at the semantic layer, a directory is divided into 256 partitions by default and can be adjusted to a maximum of 512 partitions.


D.

Routes at the service layer balance storage space and accelerate fault reconstruction.

Questions # 7:

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.

Options:

A.

TRUE


B.

FALSE


Expert Solution
Questions # 8:

The performance of a storage system can be measured by multiple indicators. In application scenarios where the I/O size is greater than or equal to 64 KB, the ________ performance indicator is the main concern for storage performance.


Expert Solution
Questions # 9:

When delivering a flash storage project, Huawei engineers introduced the trusted and secure boot technology of flash storage hardware to the customer. Which of the following statements are true about this technology?

Options:

A.

This technology uses digital signatures to verify firmware integrity and prevent firmware and operating systems from being tampered with.


B.

After a device is powered on, the initial startup module starts, and verification is performed level by level. If the verification is successful, the device starts.


C.

During secure boot, the RSA engine verifies the status of the software signature certificate and then verifies the Grub signature public key.


D.

In the overall startup process, Grub needs to be verified and loaded first. After the loading is complete, the Grub signature public key is verified.
