71. An Internet customer deployed a storage remote replication environment based on multiple flash memory devices, and during the actual business operation process, it was found that the remote replication pair had multiple operating states.

Which of the following statements about the running status of Pair is correct?

When the Pair operation status is "split", the Pair relationship between the primary LUN and the secondary LUN will be abnormally disconnected (not manually)

When the Pair operation status is "normal", the data of the primary LUN and the secondary LUN are successfully synchronized.

When the running status of the pair is "pending synchronization", you need to manually disconnect the pair relationship between the master LUN and the slave LUN to ensure the business needs of the single-LUN

After the pair is abnormally disconnected, if the pair is deleted on the master or slave side, resulting in inconsistent configurations between the master and slave sites, the pair's running status is "pending recovery"

72. Huawei's OceanStor Pacific series products can provide object storage capabilities and support cross-site disaster recovery features.

Which of the following descriptions of the cross-site disaster recovery feature of object storage is wrong?

In the cross-site disaster recovery cluster deployment mode, each site is independent, with independent DM interface, independent EC configuration, etc.

OceanStor Pacific cross-site disaster recovery uses an asynchronous replication mechanism, RPO>0, and does not support adjustment of flow control configuration

When configuring cross-site disaster recovery, if replica redundancy is used between sites, each site has a complete set of objects.

If the scenario is a backup and archiving scenario with low latency requirements, when configuring cross-site disaster recovery, you can configure the redundancy mode between sites to be EC redundancy.

73. An industry customer purchased two Huawei OceanStorPacific distributed storages and deployed them in different computer rooms. Now the engineer needs to configure the Hyperletro active-active feature in the above equipment. It is known that the arbitration mechanism at this time is static priority mode, and computer room A is the priority site. When the link between the two storage systems is interrupted, please analyze what the active-active pair operation status is at this time and what is the result after arbitration?

The active-active pair is running normally, and the arbitration result is that the volumes in computer room A and computer room B continue to run services.

The active-active pair is in the waiting-for-synchronization state. The arbitration result is that the volume in computer room A continues to run services, while the volume in computer room B stops running services.

The active-active pair is in the waiting-for-synchronization state. The arbitration result is that the volume in computer room A cannot be accessed and the volume in computer room B stops operating.

74. In actual production scenarios, the active-active feature of Huawei's converged storage can provide customers with the ability to run their services uninterruptedly. Which of the following descriptions about active-active is wrong?

When creating a hyperactive system, the local storage system is set as the priority site by default, and the remote storage system is set as the non-priority site.

When the arbitration server is inaccessible, the active-active arbitration mode is static priority mode. When an active-active pair arbitrates, the priority site obtains arbitration and provides services.

In large and medium-sized database applications, data, logs, modification records and other files are stored in different LUNs of storage devices. You can add these LUNs to the protection group and then create a hyperactive consistency group to achieve data replication consistency.

For cross-data center active-active scenarios, in long-distance transmission (generally IP networking > 25km and FC networking > 80km), the solution requires supporting wavelength division equipment to ensure network transmission latency.

75. A school customer purchased two Huawei flash storages and deployed them in different computer rooms. To ensure the reliability of data and services, engineers deployed the HyperReplication feature on the above storage.

Split

Synchronizing

76. In the structured scenario of Huawei converged storage, SmartQoS is divided into an adaptive algorithm based on negative feedback and an IO flow control management algorithm based on volume.

Which of the following descriptions of the volume-based IO flow control management algorithm is wrong?

QoS flow control requires management of the volume IO queue

If the traffic type that the user wants to limit is IOPS, then one IO consumes one token: If the performance target set is bandwidth, then one byte corresponds to one token

This scenario requires the administrator to limit the overall performance of the volume in the system. By collecting the pressure of the host on the volume, the token speed of the volume in the token bucket of each node is adjusted to achieve the purpose of limiting the overall IOP

The more tokens a volume's IO queue has, the more IO resources the system allocates to the volume.

77. When delivering the Huawei OceanStorPacific storage project, a Huawei engineer vigorously promoted the SmartEncryption data encryption feature of distributed storage to the customer. Which of the following descriptions of this feature is wrong?

This feature supports encrypted writing using any protocol such as NFS, CIFS, HDFS, or S3, and then decrypted reading using any protocol such as NFS, CIFS, HDFS, or S3

File service clients can write plain text data via NFS/CIFS/DPC protocols

Huawei OceanStorPacific series distributed storage supports hard disk encryption. All data issued by the business is stored on encrypted disks.

When reading through the DPC or NFS protocol, the encrypted disk obtains the identity authentication key from the key management server, then reads the ciphertext data in the encrypted disk and decrypts it, and then returns the plaintext data to the protocol layer, which returns the plaintext data to the client application

96. When delivering a flash storage project, Huawei engineers introduced the arbitration mechanism of the Hyperletro active-active feature to the customer.

Please analyze which of the following statements about the arbitration model is wrong?

In arbitration server mode, once a link failure occurs between arrays, the array will send an arbitration request to the arbitration server, which will comprehensively determine which end wins.

In the arbitration server mode, the arbitration device can only be deployed using a physical machine, not a virtual machine.

When the user does not configure an arbitration server, the active-active arbitration mode is the static priority mode. When an active-active pair arbitrates, the priority site obtains arbitration and provides services.

In static priority mode, if the site set as the priority site in the active-active pair fails, the non-priority site cannot automatically take over the active-active service, and the active-active service stops. In this case, you need to manually force the non-priority site to start the active-active service.

Too many threads and too frequent context switching

The startup parameter memory value is set too small

98. When optimizing the storage layer performance of Huawei flash storage, cache-related policies and configurations will be involved.

Which of the following descriptions about cache high and low water levels is wrong?

Generally, the high water mark in the cache should not be too high, and the distance between the high and low water marks should not be too small.

If the high water mark in the cache is set too high, it will affect the write performance. If the low water mark is set too low, it will affect the read performance.

Normally, the low water mark for storing dirty data in the cache should not be too low. 20% is generally recommended.

If the cache high water mark is set too high, when the front-end I/O traffic increases suddenly, I/O fluctuations and increased latency will usually occur.

99. A financial customer purchased multiple Huawei flash storage devices for daily business deployment. Which of the following descriptions of business system features in financial scenarios is wrong?

Database OLAP mainly reads large IO sequentially, and the amount of data processed in a batch determines the hotspot area.

Backup and archiving services are mainly based on sequential large I

Backup and archiving are write services, and recovery is a read service.

The database OLTP business is mainly random small IO, with more reads and fewer writes, obvious hot spots, and a small amount of sequential writes 10C,

Bill imaging business mainly involves sequential read of large IO, with relatively few metadata operations and 90% of GB-level large file write operations.

100. OLTP is the main application of traditional relational databases, mainly for basic and daily transaction processing. Which of the following descriptions about OLTP is wrong?

In OLTP business, the bandwidth indicators of the backend ports usually do not require special attention, that is, they do not need to be monitored.

From the database level, the amount of data involved in reading, writing, and modifying each transaction is very small, and many users will access it at the same time.

In OLTP business, you usually need to pay attention to the controller's average I/O response time and average CPD utilization indicators.

From a storage perspective, it is usually read sequentially, and when the read operation is in progress, the write operation data will be stored in the temporary table space

To power on the storage system again after an emergency power off, follow the steps to power on the storage system. That is, press the power button on the controller.

When all controller boxes in the cluster are powered off, you can log in to the BMC system through the BMC external management IP and execute the power-on command to power on all controller boxes in the cluster.

Before powering on the storage system, ensure that all cascading cables are correctly connected. If the cascading cable connection method is adjusted after powering on, the storage system may malfunction.

107. In Huawei's all-flash storage, the SmartDedupe & SmartCompression features can reduce redundant data space and improve the transmission and storage efficiency of the storage system.

Which of the following descriptions of this feature is wrong?

During online deduplication, the system needs to first divide the data into blocks and then calculate the fingerprint of the block data.

During the background similarity deletion process, the system does not need to divide the data into blocks and can directly calculate similar fingerprints

Background compression means that after the data stream is written to the storage medium, it is read out and compressed

Dedicated backup storage can support file system deduplication and compression

108. Erasurecode redundancy technology supports higher reliability and more flexible redundancy strategies than traditional RAID algorithms. Which of the following descriptions of the Erasurecode principle is wrong?

When data is written, it is cut into N data blocks of the same size.

109. A government customer purchased a Huawei OceanStorDorado storage system for business deployment.

During routine maintenance, an engineer discovered that the health status of the storage pool was degraded. Which of the following descriptions is correct?

The health status of the storage pool is degraded, which means that the storage pool can work normally, but cannot achieve optimal performance.

The health status of the storage pool is degraded, which means that the storage pool cannot work properly.

The health status is equivalent to the running status, so the storage device has stopped running and cannot provide space.

All subsequent LUNs created from this storage pool are in write-protected state, meaning that the business can only read the LUN but cannot write to it.

110. When delivering a Huawei distributed storage project, an engineer introduced the SmartEqualizer load balancing feature of distributed storage to the customer.

Which of the following descriptions of this feature are correct? (Multiple choice)

The default SmartEqualizer load strategy is polling, which selects nodes in order to process client requests.

If the engineer configures this feature, the system will calculate the load based on the currently configured load policy and return the appropriate management IP to the client

If the client has a custom DNS server, engineers can configure the domain name forwarding function on the server to forward the access domain name request to the DNS service of the storage system.

If the engineer configures this feature, each node in the storage system will select the SmartEqualizer master node through the Paxos algorithm (there can be two master nodes at the same time, working in active-active mode)
