What is the default space threshold for vSphere Storage DRS?
Storage DRS dynamically balance the Storage DRS cluster imbalance based on Space and IO threshold set. Default space threshold per datastore is 80% and default IO latency threshold is 15ms.
vSphere DRS helps to balance virtual machines with available resources in a vSphere cluster.
What three types of resources can be taken into account for balancing? (Choose three.)
B. physical NIC saturation of an ESXi host
C. virtual NIC saturation of a virtual machine
E. storage latency
Balancing is all about computing resources like CPU, RAM and physical NIC saturation. Vsphere DRS uses CPU, RAM and NIC to load balance virtual machines with available resources.
Upgrading vCenter Server with Microsoft SQL database fails with the following error message:
The DB User entered does not have the required permissions needed to install and configure vCenter Server with the selected DB. Please correct the following error(s): %s
What could cause this error?
A. incorrect ports open on SQL Server
B. incorrect database on the SQL server
C. incorrect compatibility mode on the SQL server
D. incorrect permission on SQL Server database
An administrator has upgraded to vSphere 6.5 and also wants to use Kerberos authentication for NFS.
Which can be done to the existing NFSv3 volumes to enable this feature?
A. Perform a storage rescan on VMFS volumes.
B. Unmount the NFSv3 datastore, and then mount as NFSv4.1 datastore.
C. Nothing. All NFSv3 mounted datastores are upgraded automatically during vSphere upgrades.
D. Perform a scan of new storage devices.
Explanation:NFS 4.1 supports the Kerberos authentication protocol to secure communication with the NFS server
An administrator has enabled vSphere Distributed Switch Health Check. The hosts connected to that Distributed Switch all display an alert:
vSphere Distributed Switch MTU supported status
The administrator has all of the VMkernel ports MTU sizes set to 1600.
Which action will remedy this problem?
A. Configure the Distributed Switch to MTU 9100.
B. Disconnect and reconnect the physical network cable.
C. Configure the physical switch to MTU 1600.
D. Disable the Distributed Switch MTU.
Explanation:You can increase the MTU size up to 9000 bytes. Therefore, a MTU of 9100 is not supported. The MTU configured in the VDS must match the physical switch configured MTU.
A vSphere Administrator is in the process of configuring replication for a virtual machine, but is not able to select the Recovery Point Objective (RPO) value of 5 minutes.
Which statement could explain why the RPO value cannot be lower than 15 minutes?
A. The OS quiescing option is selected for Replication options.
B. The virtual machine hardware version is not compatible.
C. The target and source sites use different types of datastores.
D. The target and source sites are not using VMFS 6.0 datastore.
