220-1101 Virtualization and Cloud Computing Practice Test 14 — 15 Questions

Question 1

A company runs multiple virtual machines (VMs) on a single hypervisor host. The administrator wants to ensure that if one VM is compromised by malware, it cannot read the memory contents of other VMs running on the same host. Which hypervisor feature primarily provides this protection?

Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

Virtual machine isolation. Virtual machine isolation is the hypervisor feature that prevents one VM from accessing the memory or processes of another VM on the same host. Each VM runs in its own isolated execution environment, enforced by the hypervisor's memory management unit (MMU) and hardware-assisted virtualization technologies like Intel VT-x or AMD-V. This ensures that even if a VM is compromised by malware, it cannot read the memory contents of co-resident VMs.

Answer

Resource pooling

Answer

Memory ballooning

Answer

Virtual machine snapshots

Question 2

A company runs its e-commerce website on a virtualized infrastructure. During a flash sale, the number of website visitors spikes dramatically. The virtualization platform automatically creates additional virtual web servers to handle the load and later terminates them when traffic returns to normal. This capability BEST illustrates which characteristic of cloud computing?

Accepted Answer

Rapid elasticity. The scenario describes the platform automatically scaling virtual web servers up during a flash sale and down afterward, which is the defining characteristic of rapid elasticity. This capability allows cloud resources to expand and contract quickly and automatically in response to demand, a core feature of cloud computing as defined by NIST SP 800-145.

Answer

Measured service

Answer

On-demand self-service

Answer

Resource pooling

Question 3

A company runs its customer-facing web application on a public cloud platform. The application experiences dramatic traffic spikes during promotional events. The cloud platform automatically increases the number of virtual server instances during high demand and reduces them when demand subsides. The company only pays for the compute resources consumed during the billing cycle. Which cloud computing characteristic does this configuration BEST exemplify?

Accepted Answer

Rapid elasticity. The scenario describes the cloud platform automatically scaling virtual server instances up and down in response to traffic spikes, which is the defining characteristic of rapid elasticity. This allows the company to provision and release compute resources dynamically, paying only for what is used, which is a core benefit of cloud computing.

Answer

On-demand self-service

Answer

Resource pooling

Answer

Measured service

Question 4

A server administrator live-migrates a virtual machine (VM) from one hypervisor host to another within a cluster. After the migration, the VM powers on and the operating system boots, but it cannot communicate with any network resources. Other VMs on the destination host can communicate normally. The VM uses a virtual switch with a custom port group. Which of the following is the MOST likely cause of the network connectivity loss?

Accepted Answer

The destination host does not have the required virtual switch port group configured.. When a VM is live-migrated to a new hypervisor host, the virtual switch configuration must be identical on both hosts. If the destination host lacks the custom port group that the VM's virtual NIC is attached to, the VM will lose network connectivity because the virtual switch port cannot be created. Other VMs on the destination host work normally because they use port groups that are present on that host.

Answer

The VM's virtual NIC MAC address changed during migration.

Answer

The VM's IP address is statically assigned and conflicts with a device on the destination network.

Answer

The hypervisor version on the destination host is incompatible with the VM's virtual hardware version.

Question 5

A company runs its virtualized infrastructure on a cluster of hypervisor hosts. The administrator configures the cluster to automatically move virtual machines to other hosts in the event of a planned host maintenance, minimizing downtime. The administrator also wants to ensure that virtual machines are redistributed to balance CPU and memory utilization across the cluster periodically. Which two technologies or features are being utilized? (Select TWO.)

Accepted Answer

vMotion. vMotion is the VMware technology that enables live migration of running virtual machines between hypervisor hosts with zero downtime, making it the correct choice for moving VMs during planned host maintenance. The scenario explicitly describes moving VMs automatically to other hosts for maintenance, which is the primary function of vMotion.

Answer

Fault Tolerance (FT)

Answer

High Availability (HA)

Question 6

A technician is creating a local virtual machine for software testing. The VM must have isolated virtual networking and snapshots for rollback. Which host capability is most relevant?

Accepted Answer

A hypervisor with virtual switch and snapshot support. A hypervisor provides the virtualization layer needed to create and manage VMs, including a virtual switch for isolated virtual networking and snapshot functionality for rollback. These features are essential for software testing environments where network isolation and the ability to revert to a previous state are required.

Question 9

Match each memory type to its typical use.

Accepted Answer

RAM: Temporary storage for active programs and data. RAM is volatile and holds active data; ROM is non-volatile for boot code; Cache is fast SRAM for frequent data; Virtual Memory is disk-based RAM extension; Flash is non-volatile for persistent storage. Common confusions include mixing cache with virtual memory and flash volatility.

Answer

Virtual Memory: High-speed memory between CPU and RAM

Answer

Flash Memory: Volatile memory used for temporary storage

Question 10

Match each command to its function in Windows.

Accepted Answer

ping: Tests connectivity to a remote host. The correct matches are: ping tests connectivity, tracert traces the route, ipconfig displays IP configuration, and netstat shows network connections. Common confusions involve swapping ping with ipconfig or tracert with ipconfig.

Answer

ping: Displays IP configuration

Answer

ipconfig: Traces the route to a destination

Question 11

A small design studio wants to let employees run Windows-only CAD software on their macOS laptops without buying new hardware. The IT consultant proposes installing a Type 2 hypervisor on each Mac so a Windows guest OS runs alongside macOS. Which statement best describes what the consultant must ensure for this solution to work?

Accepted Answer

The Mac must have a CPU that supports hardware-assisted virtualization and virtualization must be enabled, so the Type 2 hypervisor can run the guest efficiently while macOS remains the host OS.. Running Windows software on a macOS laptop while keeping macOS usable calls for a Type 2 (hosted) hypervisor, which installs as an application on the existing operating system and launches the guest as a process. That model requires CPU virtualization extensions to be present and enabled so the guest can execute efficiently rather than through slow binary translation.

Answer

The Mac must be wiped and configured with a Type 1 hypervisor, because only bare-metal hypervisors can run Windows guests on Apple hardware.

Answer

The Windows guest must be assigned a dedicated physical GPU passed through from the Mac, because a Type 2 hypervisor cannot share the host's graphics hardware.

Answer

The Mac must run a container runtime such as Docker instead of a hypervisor, since containers isolate the CAD application without needing a full Windows OS.

Question 12

A regional accounting firm wants to move its file server to a cloud-hosted virtual machine. The partners require that the data never leaves the firm's own building and that the VM disks remain on hardware the firm owns, while still gaining self-service provisioning and pooled resources for the IT team. Which cloud deployment model best satisfies these requirements?

Accepted Answer

Private cloud, because the pooled, self-service infrastructure is provisioned for and operated for the firm's exclusive use on hardware it controls.. Cloud deployment models differ in who owns and can access the underlying infrastructure. A private cloud keeps pooled, self-service, elastic resources dedicated to one organization, so placing it on hardware inside the firm's own building meets the requirement that data never leaves and disks remain on firm-owned equipment, unlike public, community, or hybrid models that involve external infrastructure.

Answer

Community cloud, because several accounting firms can share the same infrastructure and split the operating costs among the participating organizations.

Answer

Hybrid cloud, because combining on-premises hardware with a public cloud provider automatically keeps all data inside the firm's building.

Answer

Public cloud, because the provider's shared infrastructure already delivers pooled resources and self-service provisioning at the lowest cost.

Question 13

A small accounting firm wants to move its email, calendar, and document editing to a cloud service so employees can work from any device with a browser. The firm does not want to manage operating systems, patch servers, or install applications locally. Which cloud service model should the IT consultant recommend?

Accepted Answer

Software as a Service (SaaS). The firm needs ready-to-consume applications with no server, operating system, or application maintenance on its side. That is the defining characteristic of Software as a Service, where the provider manages everything up to the application layer. IaaS, PaaS, and DaaS all leave some infrastructure, runtime, or desktop management with the customer, so they do not satisfy the stated requirements.

Answer

Platform as a Service (PaaS)

Answer

Desktop as a Service (DaaS)

Answer

Infrastructure as a Service (IaaS)

Question 14

A company is deploying a Type 1 hypervisor on a new host server and must decide which guest resources to configure. The workloads include a database server, a file server, and several test machines. Which two resource allocations must be planned directly on the hypervisor host before the guest virtual machines can run? (Choose two.)

Accepted Answer

Memory assigned to each virtual machine. Host resource planning for a Type 1 hypervisor centers on partitioning physical CPU, memory, storage, and network capacity among guests. Virtual CPU counts and memory assignments are configured on the host and directly determine whether and how well each virtual machine runs. DNS addresses, backup schedules, and antivirus agents are configured inside the guest or by separate management tools and are not host-level allocation prerequisites.

Answer

The domain name system server address used by guests

Answer

The backup schedule for each virtual machine

Answer

The antivirus agent installed in each guest

Question 15

A software developer needs a disposable environment to test an application on Windows, Linux, and macOS without buying three computers. The developer wants to run each operating system in its own isolated instance on a single laptop and discard the instance afterward. Which solution best meets the requirement?

Accepted Answer

Use a Type 2 hypervisor to create virtual machines on the laptop. The developer needs multiple isolated operating systems running simultaneously on one laptop and the ability to discard them easily. A Type 2 hypervisor runs as an application on the existing operating system and supports snapshots, clones, and disposable guests, which fits this workflow. Type 1 hypervisors target bare-metal servers, dual-boot runs only one operating system at a time, and DaaS adds cost and network dependence without the local disposable workflow.

Answer

Subscribe to a Desktop as a Service provider for each operating system

Answer

Install a Type 1 hypervisor directly on the laptop hardware

Answer

Configure a dual-boot setup with each operating system on a separate partition
