Question 2

Which of the following are correct regarding the Huawei Oceanstro 9000 V100R001C30 products for video monitoring services? (multiple choice)

Accepted Answer

A: The securevideo feature uses a 4 + 1 protection level to improve the reliability of the video data storage device.D: After the securevideo feature is turned on, the file corruption event is reported while reading and writing files, but the data recovery failure alarm is no longer reported.

Question 3

In Huawei OceanStor 9000, the client that processes the write request performs data fragmentation according to the protection level specified in the file, divides the data chip, writes the corresponding node on power-saving memory, and then calculates the parity of each node data pieces, and writes to each node's power-saving memory.  After the node writes the power-save memory, the write operation is successful.

Accepted Answer

In Huawei OceanStor 9000, the write operation is considered successful after the data is written to the cache, not the power-saving memory. The power-saving memory is used for other purposes, such as reducing power consumption during idle periods.

Question 4

A client has 1100GB of data, including a backup window of 3 hours. The customer network uses GE networking. In order to meet customer backup requirements, you can only choose LAN free backup networking.

Accepted Answer

LAN-free backup networking is a type of backup networking that does not use the LAN for data transfer. This can be useful in situations where the LAN is congested or unreliable, or where the customer does not want to use the LAN for backup traffic. In this case, the customer has a large amount of data to back up and a short backup window, so LAN-free backup networking is a good option.

Question 5

Scale out is a scale-out architecture that upgrades storage systems typically by increasing the number of nodes by expanding more controllers to meet user data growth demand. Huawei OceanStor V3 storage system supports the use of smart IP card to achieve IP scale out.

Accepted Answer

The Huawei OceanStor V3 storage system supports scale-out architecture by adding more nodes or controllers to handle increased data demands, and it can use smart IP cards to facilitate IP scale-out.

Question 8

Which Huawei oceanstro V3 storage system prefetch strategy is correct?

Accepted Answer

Intelligent prefetching is suitable for scenarios where the data access pattern is not predictable, such as a single data stream read application or when the sequence of read applications cannot be determined.

Question 9

In OceanStoe VIS6600T delivery scenarios, multiple vendors are often protected. To avoid unpredictable compatibility issues during project implementation you need to collect compatibility information before the project is implemented. The compatibility information collected below is in accordance with the specifications. (multiple choice)

Accepted Answer

The answer of In OceanStoe VIS6600T delivery scenarios, multiple vendors...

Question 10

In the OceanStor VIS6600T dual-redundant switch network environment, using OceanStor Toolkit inspection found that "multi-path state detection "does not pass the inspection report.  It is found that there are two routes in the 4 paths of the VIS6600T device's 0 node to each LUN of the array. The path status is disabled. According to the analysis, the switch port connected to port 0 of port A0 of node 0 on node 0 of the VIS6600T is visible on the optical switch. The received optical power is much lower than the rated power of the optical module. What actions should be taken to fix this?

Accepted Answer

The answer of In the OceanStor VIS6600T dual-redundant switch network...

Question 11

According to the backup plan, the storage capacity required by site A is 3000GB and the storage capacity required by site B is 1500GB. The deduplication ratio is 3.  Based on this, what is the back end capacity?

Accepted Answer

The answer of According to the backup plan, the storage...

Question 12

VMware cluster high availability technology enables proxies and Vcenter servers on each physical virtualization host to perform proxy communications. Vcenter retry and arbitration can be used to determine if there is a failure of this host

Accepted Answer

VMware cluster high availability technology enables proxies and Vcenter servers on each physical virtualization host to perform proxy communications. Vcenter retry and arbitration can be used to determine if there is a failure of this host.

Question 13

Database applications are one of the important applications supporting storage arrays. Different application configurations and parameter settings may affect the service performance. In order to store arrays (such as OceanStor V3 series storage) with SQL server applications with the best performance, which of the following statements is wrong:

Accepted Answer

The SQL Server database instance memory size and recovery mode do affect the performance of the database. Memory size impacts how much data can be cached, and recovery mode affects transaction logging and recovery processes.

Question 14

There are multiple types of disks in a hard disk domain in the OceanStor V3 storage system. If you add one SAS disk to the hard disk domain, the topology will be load balanced as which of the following?

Accepted Answer

The answer of There are multiple types of disks in...

Question 15

For commonly used SQL Server 2005 and 2008, users can connect to the specified server through the SQL Server Management Studio tool Database Engine. There are two connections in the connection group authentication method. Which client application connection method can provide the required landing User ID and password?

Accepted Answer

SQL Server Authentication requires a user to provide a User ID and password to connect to the database engine.

Question 16

When designing SQL server database disaster recovery, the calculation of disaster recovery capacity must consider which of the following file size? (multiple choice)

Accepted Answer

The disaster recovery capacity must consider the size of data files and log files as they contain the actual data and transaction logs necessary for recovery.

Question 17

Which backup agents in WMware VADP Data Backup Reads the model of backup data through TCP / IP network

Accepted Answer

NBD (Network Block Device) reads the backup data over a TCP/IP network.

Question 18

In dual active disaster recovery solution architectures, the two FC switches will use the same domain ID after cascading to divide the zone.

Accepted Answer

In a dual active disaster recovery solution, each FC switch must have a unique domain ID to avoid conflicts and ensure proper communication and zoning.

Question 19

The WORM feature of OceanStor V3 adds the WORM attribute to the common file system so that files in the file system can only be read not be written.

Accepted Answer
