Question 6
A customer is planning to deploy a vSAN cluster to host their in-house distributed ERP system. The hardware specifications for their server nodes include: ✑ 2 x Intel Xeon CPU E5-2697 v3 @ 2.60GHz ✑ 1TB memory Which boot device is supported for the vSAN ESXi nodes for this customer?
A 16GB single-level cell (SLC) SATADOM device must be used.
A 4GB USB or SD device must be used.
A 16GB multiple-level cell (MLC) SATADOM device must be used.
ESXi Hosts must boot from a PMEM device.
Question 7
A company hosts a vSAN 7 stretched cluster for all development workloads. The original sizing of a maximum of 250 concurrent workloads in the vSAN cluster is no longer sufficient and needs to increase to at least 500 concurrent workloads within the next six months. To meet this demand, the original 8-node (4-4-1) cluster has recently been expanded to 16 nodes (8-8-1). Which three additional steps should the administrator take to support the current growth plans while minimizing the amount of resources required at the witness site? (Choose three.)
Add the new vSAN witness appliance to vCenter Server.
Deploy a new large vSAN witness appliance at the witness site.
Configure the vSAN stretched cluster to use the new vSAN witness.
Deploy a new extra large vSAN witness appliance at the witness site.
Upgrade the vSAN stretched cluster to vSAN 7.0 U1.
Configure the new vSAN witness as a shared witness appliance.
Question 8
Upon investigating a workload performance issue, a vSAN administrator observed a high backend IOPs on a vSAN cluster. Which two causes explain this behavior? (Choose two.)
The cluster DRS threshold has been set to Aggressive.
There is a vSAN node failure.
The vSAN Resync throttling is enabled.
The object repair timer value has been increased.
The vSAN policy protection level has changed from FTT=0 to FTT=1.
Question 9
An administrator wants to check the performance metrics for the workloads and their virtual disks that are running on a vSAN cluster, but no statistical charts are displayed in the vSphere client. Why is this behavior being seen?
vSAN network diagnostic mode is not enabled.
vSAN proactive tests haven't been run yet.
vSAN performance service is turned off.
vSAN performance verbose mode is not enabled.
Question 10
During a maintenance action on a vSAN node, a vSAN administrator noticed that the default repair delay time is about to be reached. Which two commands must be run to extend the time? (Choose two.)
/etc/init.d/vsanmgmtd restart
esxcli system settings advanced set -o /VSAN/ClomRepairDelay -i 50
esxcli system settings advanced set -o /VSAN/ClomRepairDelay -i 80
