Which two statements are true for Predictive DRS? (Choose two.)

1. A. It balances resource utilization for virtual machines with unpredictable utilization patterns.
2. B. It integrates DRS with vRealize Operations Manager to balance workloads for virtual machines before resource utilization spikes occur.
3. C. It balances resource utilization based on a threshold’s algorithm that runs each night.
4. D. It determines the best placement and balance of virtual machines based on a threshold’s algorithm that runs each night in vCenter Server 6.5 Database.

Correct Answer: BC
Predictive DRS
Predictive DRS is a new feature that leverages the predictive analytics of vRealize Operations Manager with the powerful resource scheduler algorithm of vSphere DRS. Together, these two products enable workload balancing for certain VMs before resource utilization spikes occur, potentially eliminating a great amount of resource contention that might have occurred in the past. vRealize Operations Manager runs its dynamic thresholds algorithm nightly against the VMs on which it collects data. These dynamic thresholds create forecasted metrics for the future utilization of the VMs. The metrics are then passed to vSphere DRS to determine the best placement and balance of VMs before resource utilization spikes occur. Predictive DRS helps prevent resource contention on hosts that run VMs with predictable utilization patterns.

Which statement is true regarding Network-Aware DRS?

1. A. Network-Aware DRS will perform load-balancing based on the communication of virtual machines with one another.
2. B. Network-Aware DRS is enabled through DRS advanced options.
3. C. Network-Aware DRS only generated suggested moves; administrators must go in and accept each Network-Aware DRS suggestion manually.
4. D. Network-Aware DRS will perform a final check during regular DRS load-balancing to ensure that the destination host is not network saturated.

Correct Answer: D

An administrator attempts to manually reclaim space on thin-provisioned VMFS6 volumes but finds that no additional space is being recovered.
Which could be causing this?

1. A. vSphere 6.5 does not support manual UNMAP.
2. B. The manual UNMAP operation has been moved to the vSphere web client.
3. C. The VASA version is use is incompatible.
4. D. UNMAP is automated for VMFS6.

Correct Answer: D
The additional space is not recovered because UNMAP is automated for VMFS 6. To get additional space recovered using the manual reclaim process, you need to remove UMAP from being automated for VMFS 6.

A security officer has issued a new directive that users will no longer have access to change connected network adapters to limit denial of service on a virtual machine.
Which two correct virtual machine advanced configuration parameters will accomplish this7 (Choose two.)

1. A. isolation.device.connectable.disable = "TRUE"
2. B. isolation.de.ice.edit.disable - "FALSE"
3. C. isolation.device.connectable.disable = "FALSE"
4. D. isolation.device.edit.disable = “TRUE”

Correct Answer: AD
Prevent a Virtual Machine User or Process from Disconnecting Devices in the vSphere Web ClientUsers and processes without root or administrator privileges within virtual machines have the capability to connect or disconnect devices, such as network adaptors and CD-ROM drives, as well as the ability to modify device settings. To increase virtual machine security, remove these devices. If you do not want to permanently remove a device, you can prevent a virtual machine user or process from connecting or disconnecting the device from within the guest operating system.

Which three operations can cause VMFS metadata updates? (Choose three.)

1. A. Restarting a VM using the guest OS.
2. B. Launching a VM console.
3. C. Migrating a VM with vMotion.
4. D. Powering a VM on or off.
5. E. Expanding a VMFS datastore.

Correct Answer: CDE
Metadata is updated each time you perform datastore or virtual machine management operations. Examples of operations requiring metadata updates include the
following:
Creating, growing, or locking a virtual machine file Changing a file\'s attributes
Powering a virtual machine on or off Creating or deleting a VMFS datastore Expanding a VMFS datastore Creating a template
Deploying a virtual machine from a template Migrating a virtual machine with vMotion Reference:
