Virtualization and Cloud Computing

A technician installs a Type 2 hypervisor on a modern desktop to run a 64-bit guest OS for testing. The host has 32 GB of RAM and ample disk space, but when the technician tries to create the virtual machine, the hypervisor reports that hardware virtualization is unavailable and refuses to start 64-bit guests. What should the technician do first to resolve this?

A technician needs to run three virtual machines simultaneously on a workstation using a type 2 hypervisor. Each VM requires 4 GB of RAM to run its guest OS, and the host operating system needs at least 8 GB to remain responsive. What is the minimum amount of physical RAM the workstation should have to support this configuration?

A technician uses a client-side hypervisor to test a new software patch on a virtual machine. Before applying the patch, the technician wants a quick way to capture the VM's current state so it can be instantly restored if the patch causes problems, without cloning the entire virtual disk. Which hypervisor feature should be used?

A security analyst runs several virtual machines on a workstation to detonate suspicious files. She wants each VM to have full network functionality among the VMs so she can watch how malware attempts to spread laterally, but she must guarantee that no traffic ever reaches the physical LAN or the internet. Which hypervisor network setting should she assign to these VMs?

Several regional hospitals want to share a common cloud platform that meets strict healthcare compliance requirements. Each hospital is a separate organization, but they agree to jointly fund and govern the shared infrastructure so costs and regulatory controls are distributed among the participating members. Which cloud deployment model best fits this arrangement?

A company runs its customer database on private, on-premises servers to satisfy strict data-residency regulations. During seasonal sales, its web front-end experiences huge traffic spikes that exceed local capacity, so the company temporarily provisions additional web servers from a public cloud provider while keeping the regulated database in-house. Which cloud deployment model does this describe?

A company wants to consolidate several aging physical servers onto a single powerful host machine in their data center. The goal is to run multiple virtual servers with the best possible performance and no dependency on an underlying desktop operating system. Which type of hypervisor should the technician deploy?

A startup needs to deploy several virtual servers to host a custom application. They want the cloud provider to supply the underlying compute, storage, and networking hardware, but the company insists on installing and fully controlling the operating systems, patching, and application stack themselves. Which cloud service model best fits these requirements?

A finance manager reviews the company's monthly cloud invoice and notices the charges rise and fall each month based on the exact amount of storage consumed and the number of compute hours actually used. The provider itemizes usage down to the gigabyte and CPU-hour. Which cloud characteristic does this billing model demonstrate?

A software development team wants to build and deploy a custom web application without managing operating system patches, runtime updates, or the underlying servers. They need the cloud provider to supply a ready-made platform with the programming framework, database, and web server already configured so they only write and deploy code. Which cloud service model best fits this requirement?

A hospital must run its patient records application on infrastructure that is dedicated solely to the organization, giving IT full control over hardware, network, and security to meet strict regulatory compliance. They still want on-demand self-service and resource pooling internally. Which cloud deployment model best fits these requirements?

A startup wants to deploy its web application without buying any hardware. They sign up with a large cloud provider where their virtual machines run on the same physical infrastructure used by thousands of other unrelated companies, and they pay only for the resources they consume. Which cloud deployment model are they using?

An online retailer experiences unpredictable traffic surges during flash sales, sometimes needing 10 times the normal server capacity for only a few hours before demand drops back to baseline. The IT manager wants a cloud characteristic that automatically adds compute resources when traffic climbs and removes them when the surge ends, without manual intervention. Which cloud characteristic best describes this capability?

A small business owner wants to give her 12 employees access to a full office productivity suite and email without purchasing, installing, or patching any application software on individual computers. Users should simply log in through a web browser and start working, and the vendor handles all updates and maintenance. Which cloud service model best fits this requirement?

A company migrates its file storage to a public cloud provider. During a review, an auditor notes that the physical servers and storage arrays hosting the company's data are the same hardware used by dozens of other unrelated customers, with logical isolation separating each tenant's data. Which cloud characteristic does this describe?

A security analyst needs to safely analyze suspicious files on a single dedicated laptop. She wants to run several isolated operating system instances so that if a sample infects one instance, it cannot reach the host OS or the corporate network. What is the MOST important reason to use client-side virtualization for this task?
