質問 1:An infrastructure architect is designing a vSAN Cluster that must satisfy these requirements:
* support storage policies with 2 failures - RAID-1 (Mirroring)
* support storage policies with 2 failures - RAID-6 (Erasure Coding)
virtual machines must maintain compliance with the storage policy rules above when one host is in maintenance mode with full data migration What is the minimum number of hosts needed to achieve these design requirements?
A. 8
B. 6
C. 7
D. 5
正解:B
質問 2:A company has reserved the last Saturday of the month to conduct server maintenance. An administrator is allowed to perform maintenance from 5 AM to 12 PM. During the upcoming maintenance window, the administrator will upgrade the controller driver, controller firmware, and vSphere version.
Environment details:
* vCenter is already at the latest version
* 5 node vSAN cluster
* The VMs are using a mix of RAID-0, RAID-1, and RAID-5 policies
* Each node is storing 20 TBs worth of VMs
Which maintenance mode option will allow an administrator to successfully perform the required upgrades, while ensuring all VMs remain online?
A. Full data migration
B. No Data Migration
C. Admission Control Enabled
D. Ensure Accessibility
正解:B
質問 3:A 3-node All-Flash vSAN cluster has this configuration:
* One disk group per host
* All disk groups have identical make & model disks of an 800GB NVMe SSD cache and 2x 4TB SAS SSDs each An administrator has been tasked with expanding storage capacity by adding one additional disk group with this configuration:
1.6TB SAS SSD cache and 1x 4TB SAS SSDs
Assuming all the disks are compliant with the vSAN HCL, which is true?
A. The additional disk group would make this cluster an unsupported configuration.
B. The additional disk group will generate an 'Advanced vSAN Configuration in sync' health check warning.
C. The additional disk group would not be possible as vSAN would not allow it.
D. The additional disk group would work and be fully supported by VMware support.
正解:A
質問 4:A healthy vSAN Stretched Cluster has the existing vSAN Witness Host swapped for a new vSAN Witness Host using the "Change Witness Host" wizard.
If the administrator takes no further action, which two does the vSAN Health Check report show? (Choose two.)
A. Performance Service - Stats DB Object - object exists - green
B. Data - vSAN Object Health - Reduced availability with no rebuild
C. Data - vSAN Object Health - Healthy
D. Performance Service - Stats DB Object - object health - red
E. Performance Service - Stats DB Object - object health - green
正解:B,D
質問 5:An administrator needs to perform an urgent maintenance activity on a host that is part of a 3-node vSAN cluster. All the disk groups in the cluster are balanced. They need to choose a maintenance mode option to ensure:
*There is no downtime to any of the virtual machines running in the cluster
*Virtual Machine accessibility is maintained
*No data is left on the host that could possibly cause data loss
Which statement is true if the administrator chooses 'Ensure accessibility' as the maintenance mode option?
A. Data Migration is minimized even if VM becomes non-compliant with its storage policy.
B. Only VMs will be migrated with vMotion and no data migration will occur.
C. All VMs and data on host will be migrated to ensure that there is no data loss.
D. All data on the host going into maintenance mode will be evacuated.
正解:A
質問 6:A customer has lost connectivity to one of their sites In a vSAN Stretched Cluster.
When connectivity is restored, what DRS setting will ensure VMs are not migrated back before resyncs are complete?
A. DRS configured in Fully Automated mode
B. DRS configured in Manual Mode
C. DRS configured in Partially Automated mode
D. DRS turned off
正解:B
質問 7:Refer to the exhibit:
The vSAN Health service is reporting VSAN Cluster Partition' warning. The partition list shows all hosts from rack 1 in a single partition and all hosts from rack 2 in another partition.
Which hardware component requires investigation to resolve the cluster partition?
A. core switch
B. ToR switches
C. vSAN Master node
D. NICs on each host in Rack 2
正解:B
質問 8:Which two storage policy changes require a full rebuild of all components for an object? (Choose two.)
A. Increase the number of disk stripes for an object from 2 to 3.
B. Disable object checksum on an object.
C. Reduce the Primary Failures to Tolerate from 2 to 1 for an object using a failure tolerance method of RAID-1 (Mirroring).
D. Change the failure tolerance method of an object from RAID-1 (Mirroring) to RAID-5 (Erasure Coding).
E. Increase the IOPS limit for an object.
正解:C,D
