Question 11
In Simpana software, incremental backup means:
A. The data that has changed since the last backup.
B. The data that has been changed since the last full backup.
C. The completion of all data backup.
D. After the initial backup, all data has back up.
Question 12
HUAWEI OceanStor 18000 Engine, SVP, Disk Enclosure, and PCI-e Switch Interconnection are applicable to certain rules and orders. Which of the following statement?
A. SVP needs to be connected multiple engines through two PCIe switches, and each engine controller needs to be connected to a PCIe switch to ensure that link redundancy and to improve reliability.
B. When the control plane is connected to a network, when the engine and the PCI-e switch are interconnected, the port 0, port A3 and PCIe port can be interconnected.
C. Huawei slot 0 and slot 5 of the OceanStor 18000 engine enclosure can be used to install SAS interface modules and interconnect disk enclosures.
Question 13
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, diagram will be balanced as follows:
A. Tier 0 disks perform data equalization.
B. All disks in the entire hard disk domain will participate in data equalization.
C. The CK of the target CKG will be released after data equalization is completed.
D. OCeanstor V3 enables cross-engine data equalization.
Question 14
Info Replicator supports copying the data at the same time, the basic attributes of the home directory, extended attributes, ACL (access control list).WORM (write-once-read-many) and CIFS / NFS share configuration information is also a wealth island from the end. When a disaster occurs, master and slave sites can quickly take over the business after the switch.
A. True
B. False
Question 15
When planning OceanStore Unified Storage Array synchronization remote replication, the following description is correct. (Multiple choice.)
A. In the scenario where the actual RPO indicator requires zero, you can choose to synchronize remote replication.
B. Synchronous remote replication can be used to map the main and secondary storage of the two sets of LUN mapping to the host to create a scenario volume instead of.
C. Synchronous remote replication on the remote disaster recovery can be well done.
D. Because synchronous remote replication does not use snapshots, after synchronous remote replication is interrupted abnormally, the data on the primary LUN needs to be resumed in reply.
Question 16
Which of the following VMWARE virtual machine scenarios can use VADP backup?
A. The storage is connected directly to the virtual machine, including RDMs, directly to iSCSI or NFS.
B. Virtual machines contain large databases.
C. The virtual machine is deployed in the AIX operating system.
D. Virtual machines contain non-Microsoft family applications.
Question 17
Database applications are one of the important applications supporting storage arrays. Storage arrays, operating systems, file systems, and database application systems, etc.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 application with the best performance, which of the following statement is wrong:
A. OLTP database generally have a large number of random write, it is recommended to choose RAID 10 to store data.
B. In order to improve write performance, all SQL server database data stored in the LUN write strategy is configured to "write back the image".
C. Because the size of the SQL server page is 8K, in order to ensure the best performance of the database, NTFS allocated block size should not be less than 8KB.
D. SQL Server database instance memory size and recovery mode of choice has no effect on the performance of the database.
Question 18
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 repair strategy of the fault contains the error?
A. Replacing the optical module of port 0 in slot A0 of node 0.
B. Replacing the light of the P0 port in the A0 slot of 0 node.
C. Replacing the optical module of the port connected to port 0 of the corresponding 0-node A0 slot on the switch.
D. Reseat the FC interface card corresponding to slot 0 of node A0.
Question 19
What commands are installed there for viewing SCSI controller information on Linux systems with Qlogic HBAs?
A. lspci | grep SCSI
B. cat / proc / scsi / scsi
C. cat / proc / scsi / qla2300 / 1 | grep port
D. lspci | grep Ethernet
Question 20
Maintaining a persistent connection between host and storage, ESXi must support multipathing. Please check out Incorrect description multipathing for VMware vSphere 5.5
A. In addition to path failover, multipathing also provides load balancing. Load balancing is the process of distributing I / O load across multiple physical paths.
B. In the event of a path failover, the virtual machine I / O delays Nintendo pump by 60s.
C. If the failover takes a long time to complete, the windows virtual machine may interrupt the I / O and eventually fail. To avoid this problem barrier, please set windows virtual machine according to the timeout to at least 30 seconds.
D. When coordinating vmware NMP and any third-party MPP installed, the PSA (Pluggable Storage Architecture) performs load and unload multipathing plug-ins;
