VMware vSphere 6 Advanced Design (VCAP6-DCV Design) — Question 50

A company is in the process of deploying a modern video-streaming application.
✑ The application is able to scale (expand and collapse) its streaming nodes in the form of CentOS 7.x 64bit virtual machines, based on demand.
✑ This IO-Intensive application has a high CPU demand and generates a significant number of disk operations (IOPS).
✑ To host the application, the company decided to implement a brand-new VMware cluster with vSphere 6.x.
✑ The company would like a significant reduction in CPU utilization as well as possible increase in throughput.
Which virtual disk adapter should be recommended for the company's physical design?

Answer options

Correct answer: B

Explanation

The VMware Paravirtual adapter is optimized for high-performance workloads and reduces CPU overhead by allowing the guest OS to communicate more efficiently with the hypervisor. The other options, such as LSI Logical Parallel and BusLogic Parallel, do not offer the same level of performance enhancement for I/O operations, making them less suitable for an IO-Intensive application.
