.Question 2Which is a characteristic of cloud infrastructure as a service model?1 pointUsers can access networking resources on the cloud through virtualizationEnd users interact directly with the physical infrastructureNo supporting services provided by IaaSData can only be stored on physical machines in the network

Which of the following is an advantage of IaaS (Infrastructure as service)?(1 Point)Complete control of the computing resources through administrative access to VMs.Portability, interoperability with legacy applications.All of the aboveEfficient and flexible renting of computer hardware.

The use of cloud infrastructure as a service (IaaS service category) implies:To reserve computing capability for the future, in case of unpredictable conditions.To understand whether the cloud provider uses a good hardware vendor.To upload your infrastructure software and application.To manage the power supply for the infrastructure.
