NEW QUESTION 18
There are often disadvantages when using mixed hardware, and uniform systems are highly advised. What are three disadvantages of using validated yet mixed hardware? (Choose three.)
- A. "Software only" solutions are inherently more secure, adhering to government regulations.
- B. "Hardware only" solutions require less latency for data aggregation.
- C. "Software only" solutions can result in a lack of simplicity for installation and maintenance. While setup and maintenance of an HCI solution might be simple you still need to configure and maintain the hardware part, which is not orchestrated by the HCI solution.
- D. Validated hardware does not mean smooth performance, which particularly applies to hardware that is seldom chosen for the hardware part of the "software only" solution.
- E. Validated yet "mixed" hardware systems may be supported by the specific original equipment manufacturers but software vendors require a master level services agreement.
- F. "Software only" HCI solutions often mean that HCI vendors do not have control over the hardware that the consumer is using. The lack of control over the hardware can result in hardware not being security-compliant (usually the case with white box solutions) or not being optimally configured for the given HCI solution.

When local writing or reading is performed, the lOVisor intercepts the read/write requests and forwards them to CVMs across the cluster This action allows non-local CVMs to be aware of the input/output requests so that they can perform the appropriate input/output action lOVisor provides which two additional functionalities? (Choose two.)
