Which of the following information about the InfoEqualizer function of Huawei OceanStor 9000 is correct? (Multiple choice)
- When using the InfoEqualizer function, you need to configure DNS. If you use an external DNS server, when configuring the DNS server, there is a setting of “reverse lookup zone name”, network ID setting in this tab, you need to input network ID in reverse order.

- The main storage using smart cache acceleration, speed up the main storage IO processing speed.
- According to the service pressure of the LUNs stored on the primary side, assign the home controllers of each LUN to the A and B controllers.
- If you are using an asynchronous remote replication scheme, you need to design a startup synchronization time based on the RPO metrics and consider the setting possible startup synchronization time during the business.

Which of the following best practice descriptions of Oralce database is correct? (Multiple choice.)
- OLAP business query output is usually a statistical value (using group by with order by), so you can set a larger SGA-target value (relative to OLTP).
- It is recommended to use UDEV UUID and drive letter binding, in Linux environment configuration Oracle database, to avoid subsequent maintenance letter changes caused by the database which can not start.
- If the database OLTP business log write is very frequent, it is recommended that the appropriate online log file up, but it is recommended not to exceed 128MB.
- In Windows2008 or windows2012 operating system environment, in order to improve I / O processing efficiency, MBR partition is created, and diskpart command is recommended to set the partition alignment.
-
Which of the following is a description of the UltraPath multipath setting? (Multiple answers)
- The mode of operation of the array can be in-controller load balancing or inter-controller load balancing.
- Load Balancing Mode Including wheel training algorithm, the maximum queue depth algorithm, the maximum workload algorithm.
- After the connection is interrupted between the LUN home controller and the host, the host accesses the LUN through the peer controller. In this case, the over-trail software defaults the switched home controller of the LUN to the remote controller.
- When multipath detects a preferred controller failure recovery, the I / O is resumed immediately at the preferred controller by default.
