Question 1 of 30

A critical financial analysis virtual machine, designated \"Alpha-Server,\" is experiencing significant performance degradation, manifesting as prolonged response times for data retrieval operations. This virtual machine is running on a vSphere 5.5 environment and is connected to a shared datastore that is currently reporting high I/O latency. Alpha-Server is configured with a single virtual disk (vmdk) utilizing the default LSI Logic SAS controller. Other virtual machines on the same datastore are also reporting occasional performance issues. Analysis of the vSphere performance metrics indicates that while CPU and memory utilization for Alpha-Server are within acceptable limits, disk read latency is exceptionally high. Which of the following actions would most effectively address the storage I/O bottleneck impacting Alpha-Server\'s performance?

Increase the SCSI queue depth for Alpha-Server's virtual disk controller.
Migrate Alpha-Server to a different ESXi host with lower datastore latency.
Reconfigure Alpha-Server to utilize the VMware Paravirtual SCSI controller.
Allocate additional vCPUs to Alpha-Server to improve processing efficiency.
