Question 44

Which of the following is the wrong mode of operation when checking on a problem with the VMFS datastore for ESXi5.5 using the VMware ondisk metadata analyzer (VOMA)? (Assume the LUN NAA ID is naa.60022a110009a8a800042e1800000000: 1).

Options:

Turn off the power of all running virtual machines or migrate these virtual machines to another data store

Use the esxcli storage vmfs extent list command to obtain the name and partition of the vmfs data store tobe backed up after the provision of number of the supported devices.

voma -m vmfs -f check -d /vmfs/devices/disks/naa.60022a110009a8a800042e1800000000:1

voma -m vmfs -f check -d naa.60022a110009a8a800042e1800000000: 1

Question 45

In simpana backup software, incremental backup means_______.

Options:

The data that has changed since the last backup is backed up.

Changed data backup since last full backup.

Full backup of all data.

After the initial backup data backup of all data.

Question 46

In the scenario of protecting the database, the slave uses the virtual snapshot method to verify the services of the production end andthe DR-side and discover the data of the DR on the disaster recovery end. What are the possible reasons that the library can not start normally? (Multiple choice.)

Options:

After a snapshot of the LUN of the redundancy site is created, the snapshot is not activated at the same time.

Disaster recovery side of the data stored in the cache, not yet written to the hard disk.

When creating a snapshot on the disaster recovery end LUN, the production end is copying data to the disaster recovery end.

The production end and disaster recovery end adopt the disaster recovery solution of incremental LUN copy, and the incremental data link is abnormal during the synchronization.

Question 47

In the OceanStor 18000 storage system, a 15K RPM SAS disk is used. Assuming that the averageseek latency of this type of disk is 6 ms. which type of disk can provide a single disk IOPS?
