B. NFS.VolumeRemountFrequency value is set to 30. C. Storage I/O Control is enabled on NFS datastore. D. NFS datastore has running or registered virtual machines. Source: -ED24BA81-E477-41E4-8271-8D7349A38941.html Note: Make sure that the datastore is not used by vSphere HA heartbeating. vSphere HA heartbeating does not prevent you from unmouting the datastore. However, if the datastore is used for heartbeating, unmounting it might cause the host to fail and restart all active virtual machines. Before unmounting a datastore, also make sure that the following prerequisites are met: No virtual machines reside on the datastore. The datastore is not managed by Storage DRS. Storage I/O control is disabled for this datastore. About this task Do not perform any configuration operations that might result in I/O to the datastore while the unmount is in progress. 78. Which two statements about vCenter HA are correct? (Choose two.)
79. Which two storage configurations on the source server are unsupported with VMware Converter? (Choose two.) 80. A vSphere administrator manages a cluster which includes critical and non-critical virtual machines. The cluster requires different permissions for contractors and non-contractors. How can the administrator exclude the contractor group from some of the critical VMs? 81. A vSphere Administrator wants to reserve 0.5 Gbps for virtual machines on each uplink on a disturbed switch that has 10 uplinks. What is the quota that should be reserved for the network resource pool? A. 10 Gbps B. 5 Gbps C. 100 Gbps D. 0.5 Gbps Explanation: if the virtual machine system traffic has 0.5 Gbps reserved on each 10 GbE uplink on a distributed switch that has 10 uplinks, then the total aggregated bandwidth available for VM reservation on this switch is 5 Gbps. Each network resource pool can reserve a quota of this 5 Gbps capacity.
