ICT18 - Virtualisation Fundamentals

What is a primary characteristic of a Virtual Machine (VM)?

• It runs directly on hardware without any software abstraction

• It operates as an independent system with its own operating system on virtualized hardware

• It is a type of server used for cloud computing

• It is a tool used for encrypting data on a network

What is one primary benefit of containerisation compared to traditional virtual machines?

• Containers handle more resources than VMs

• Containers are tied to specific hardware

• Containers start up faster and use fewer resources than VMs

• Containers can be used in cloud environments, VMs cannot

Which statement about virtual machines is correct?

• Each VM runs its own operating system and is isolated from others

• VMs cannot run different operating systems on the same host

• VMs share the same kernel as the host system

• VMs are only used for gaming

Which of the following best describes a Type 2 hypervisor?

• Runs directly on the host's hardware

• Runs on top of a host operating system

• Does not require any operating system

• Is only used in data centres

Which of the following is an example of a containerisation platform?

• VMware vSphere

• Docker

• Microsoft Hyper-V

• Citrix XenServer

What is the main function of a hypervisor?

• To manage and allocate physical resources to virtual machines

• To encrypt data on the network

• To monitor CPU temperature

• To provide internet access to VMs

Which of the following statements about virtual machines and containers is true?

• VMs are generally more lightweight than containers

• Containers share the host operating system's kernel, while VMs do not

• Containers cannot be used for web applications

• VMs and containers cannot run on the same host

Which of the following best describes containerisation?

• Running multiple operating systems on a single physical machine

• Packaging applications and their dependencies into isolated units that share the host OS kernel

• Encrypting data before storing it in the cloud

• Allocating physical resources directly to applications

What is a key difference between a Type 1 and Type 2 hypervisor?

• Type 1 runs directly on hardware, while Type 2 runs on a host operating system

• Type 1 requires more resources than Type 2

• Type 1 is only used for containers, Type 2 is only for VMs

• Type 2 does not support virtual machines

Which scenario is most suitable for using containers instead of virtual machines?

• Running multiple different operating systems on the same host

• Running legacy applications that require a specific OS version

• Isolating hardware resources for security reasons

• Deploying lightweight, scalable microservices that need fast startup times
