An administrator wants to monitor virtual machines on a host and send notifications when memory usage reaches 80%.
What should the administrator create in vCenter Server to accomplish this?

1. A. A host alarm that will monitor virtual machine memory usage and set a trigger to email the notification.
2. B. A vCenter Server alarm that will monitor virtual machine memory usage and set an action to email the notification.
3. C. A host alarm that will monitor virtual machine memory usage and set an action to email the notification.
4. D. A vCenter Server alarm that will monitor virtual machine memory usage and set a trigger to email the notification.

Correct Answer: B
For notifications, set the vCenter Server alarm to monitor virtual machine memory usage and configure set action to email the notification.

An administrator is experiencing network connectivity issues between virtual machines. The virtual machines and hosts are configured as follows:
✑ VM1 is running on Host1
✑ VM2 is running on Host2
✑ Both Host1 and Host2 are attached to the vSphere Distributed Switch dvSwitch1
✑ Both Host1 and Host2 are using vmnic0 and vmnic1 on dvSwitch1
✑ Both virtual machines are using the default portgroup for network traffic
What are three settings the administrator should investigate while troubleshooting the connectivity issue? (Choose three.)

1. A. VLANs of the physical NICs
2. B. Failover order of the uplinks
3. C. Virtual NIC connectivity to the dvSwitch
4. D. Security policy of the portgroup
5. E. Traffic shaping on the portgroup

Correct Answer: ABC
To find out connectivity problems, you can use VLANs of the physical NICs, virtual MIC connectivity to the dvswitch and failover orders of the uplinks.

Refer to the Exhibit.

An administrator receives vRealize Operations alerts for the Health of the virtual machine PVMAPP_0 as shown in Exhibit 1:
The administrator clicks on the Analysis pane, as shown in Exhibit 2:

Based on the exhibits, what action would correctly address the performance problems observed?

1. A. Increase the number of vCPUs for PVMAPP_0.
2. B. Increase the allocation of memory for PVMAPP_0.
3. C. Increase the Memory limit for PVMAPP_0.
4. D. Increase the reservation in MHz for vCPUs for PVMAPP_0.

Correct Answer: A
The CPU workload is high so the logical step si to increase the number of vCPUs for PVMAPP_0.
