Huawei H13-231 問題集

質問 1：
A company purchased a batch of TaiShan servers to storage to the original distributed Ceph for expansion. Among them, Ceph uses the CRUSH algorithm to achieve fast and accurate data storage under large-scale clusters, and at the same time, it can achieve the smallest data migration in the event of hardware failure or expansion of hardware equipment. For CRUSE main factors affecting the algorithm are? (Multiple choice)
A. Storage file size
B. The number of OSDs in the current system
C. OSD status in the current system
D. Storage policy configuration
正解：B,C,D

質問 2：
Taishan server acceleration engine includes symmetric encryption, asymmetric encryption and digital signatures, compression and decompression algorithms, for accelerating SSL / TLS applications and data Refined and Popular, can significantly reduce the processing load. Improve processor efficiency. Which of the following statements is correct?
A. Support symmetric encryption algorithm SM4, and only CBC mode
B. Does not support digest algorithm SM3
C. Support symmetric encryption algorithm SM4, and only CTR mode
D. Support asymmetric algorithm RS Key Sizes 1024/2048/3072/4096
正解：D

質問 5：
An Internet company purchased a batch of TaiShan servers to expand the original distributed storage Ceph. Which of the following services allows block devices to be directly mounted like hard disks and supports thin provisioning, snapshots, and cloning?
A. CephFS
B. RBD
C. RADOSGW
D. RELEASED
正解：B

質問 6：
The Linux application software installation package in RPM and deb format is related to the operating system version and CPU architecture. Therefore, the installation package based on the X86 server cannot be used on the TaiShan server. You can obtain the TaiShan server compatible installation package for migration.
A. False
B. True
正解：B

質問 7：
A certain office purchases a batch of TaiShan servers to expand the existing distributed storage Ceph. The Ceph storage cluster receives files from the client and stores them (the entire process of the OSD node in the order of File>object mapping, Object->PG mapping and PG>OSD mapping to achieve device data storage).
A. False
B. True
正解：B

質問 8：
Which of the following description about the management features of server clusters is incorrect?
A. The system administrator can remotely manage a cluster or even a group of clusters, just like in a stand-alone system.
B. All server clusters can be managed by WebUI
C. The cluster software for special application scenarios has independent management interfaces and methods.
D. An independent server cluster is equivalent to a stand-alone system on the management level.
正解：B

質問 9：
When engineers deliver hyper-converged scenarios built by Huawei rack servers, they need to use external switch networking. When each node of the server is configured with 2xGE+4X10GE network cards, two GE network ports are generally planned for management, two GE network ports for storage, and two 10GE networks for business.
A. False
B. True
正解：A
