Virtualization and Cloud Computing

Correct Answer: To manage virtual machines

A hypervisor, also known as a virtual machine monitor, is a type of software, firmware, or hardware that creates and runs virtual machines. Its primary role is to manage these virtual machines, allowing multiple virtual environments to run on a single physical host. Each virtual machine operates as if it were a separate physical machine. The other answers, such as managing physical servers, managing network traffic, or managing storage devices, are incorrect because, while hypervisors can indirectly influence these areas via the virtual machines they control, their main function is specifically related to managing virtual machines not physical servers, network traffic, or storage devices.

Correct Answer: Use Private Virtual Network

The best solution for the user to access the company's internal network without being on the same network as other users is to 'Use Private Virtual Network'. A private virtual network or a virtual private network (VPN) creates a secure connection to the internal network over the internet. This makes it ideal for remote users to access resources on the internal network from outside the company. 'Connect to the physical network' isn't the best option as it wouldn't necessarily ensure the user is separate from other users. 'Use Bridged Networking' might not effectively isolate the user from the rest of the network, as it creates a link between the virtual and physical network. 'Enable Virtual Machine Port Mirroring' is used more for monitoring network traffic and wouldn't necessarily meet the requirement for isolation.

Correct Answer: Scalability

The primary benefit of cloud computing is Scalability. The cloud allows businesses to easily scale up or down their computing needs as needs change. This dynamic adaptability is a unique characteristic of cloud computing. Data Security, Cost Savings, and Improved Performance are also benefits of cloud computing but they are not the primary. For instance, Data security, while critical, might not be improved in a cloud set up as it might not offer same level of control as traditional on-premise system. Cost Savings and Improved Performance are also major benefits but they can occur in other forms of computing too.
