220-1202 Practice Test 21 — 15 Questions

Question 1

A technician is tasked with deploying a new virtual machine for a client who needs to run a legacy application that requires a specific configuration. The client wants the VM to be isolated from the host operating system but still needs to access physical USB devices connected to the host. Which type of virtualization technology should the technician use?

Accepted Answer

Type 2 hypervisor. This question tests knowledge of virtualization types and their capabilities. Type 1 hypervisors run directly on hardware and provide strong isolation, but they lack direct USB passthrough in many configurations. Type 2 hypervisors, like VMware Workstation or VirtualBox, run on top of an OS and commonly support USB passthrough, making them suitable for this scenario.

Answer

Type 1 hypervisor

Answer

Container-based virtualization

Answer

Desktop virtualization (VDI)

Question 2

A company uses a cloud-based file storage service. An employee reports that when they try to upload a large video file, the upload fails after several minutes of progress. The employee's internet connection is stable and other uploads of smaller files work fine. What is the most likely cause of this issue?

Accepted Answer

The file exceeds the maximum upload size allowed by the service.. This scenario tests troubleshooting cloud storage issues. The correct answer is C because many cloud services have file size limits, and a large video file may exceed that limit. The other options are less likely given that other uploads work and the connection is stable.

Answer

The employee's computer has insufficient RAM.

Answer

The cloud service's server is temporarily overloaded.

Answer

The employee's account has been suspended.

Question 3

A technician is configuring a new virtual machine for a developer. The developer needs to run multiple isolated environments for testing, but the host machine has limited storage space. Which type of virtual disk configuration should the technician use to minimize storage usage while still allowing the VM to grow as needed?

Accepted Answer

Thin provisioning. This question tests knowledge of virtual disk types. Thin provisioning allocates storage on demand, using only the space actually used by the VM, which is ideal for saving storage. Thick provisioning pre-allocates the full disk size, wasting space. Dynamic disks are a Windows concept, not a VM disk type.

Answer

Thick provisioning

Answer

Fixed-size disk

Answer

Dynamic disk

Question 4

A user reports that their virtual machine running on a Type 2 hypervisor is extremely slow. The host machine has 16 GB of RAM, and the VM is configured with 8 GB. The host's task manager shows 90% memory usage. What should the technician do to improve the VM's performance?

Accepted Answer

Reduce the amount of RAM allocated to the VM to 4 GB.. This scenario tests resource allocation in virtualization. The host is running low on memory, causing the VM to be slow. Reducing the VM's RAM allocation will free up memory for the host and improve overall performance. Increasing vCPUs or changing disk type won't address the memory bottleneck, and enabling hyper-threading is not a direct solution.

Answer

Increase the number of virtual CPUs assigned to the VM.

Answer

Change the virtual disk from thin to thick provisioning.

Answer

Enable hyper-threading on the host CPU.

Question 5

A company is moving its on-premises email server to a cloud-based service. The IT manager is concerned about data security and wants to ensure that the email data is encrypted both at rest and in transit. Which cloud service model is the company most likely using?

Accepted Answer

Software as a Service (SaaS). This question tests understanding of cloud service models. Email as a service is a common SaaS offering, where the provider manages the infrastructure, platform, and software. PaaS and IaaS would require the company to manage the email application itself, which is less likely for a simple migration.

Answer

Infrastructure as a Service (IaaS)

Answer

Platform as a Service (PaaS)

Answer

Desktop as a Service (DaaS)

Question 6

A technician needs to deploy a virtual machine for a client who requires a specific operating system that is not supported by the hypervisor's default settings. The technician has the ISO file for the OS. What should the technician do to install the OS on the VM?

Accepted Answer

Mount the ISO file as a virtual CD/DVD drive and boot from it.. This question tests the process of installing an OS on a VM. The correct method is to mount the ISO file as a virtual optical drive and boot from it. Copying the ISO to the virtual disk or using a USB drive would not work directly, and the hypervisor's default settings are not relevant to OS compatibility.

Answer

Copy the ISO file directly to the virtual hard disk.

Answer

Use a USB flash drive with the ISO and plug it into the host.

Answer

Change the hypervisor's default settings to support the OS.

Question 7

A user reports that their cloud-based virtual desktop (VDI) is disconnecting frequently. The user's internet connection is stable, and other cloud services work fine. The technician checks the VDI's resource usage and finds that the virtual machine's RAM is consistently at 95% usage. What should the technician do to resolve the disconnections?

Accepted Answer

Increase the amount of RAM allocated to the VDI.. This scenario tests advanced troubleshooting of VDI performance. High memory usage can cause the VM to become unresponsive, leading to disconnections. Increasing the VM's RAM allocation directly addresses the resource bottleneck. Reducing RAM would worsen the problem, and network or GPU issues are not indicated.

Answer

Reduce the amount of RAM allocated to the VDI.

Answer

Reinstall the VDI client software on the user's device.

Answer

Enable GPU acceleration for the VDI.

Question 8

A company uses a private cloud for its internal applications. The IT team wants to ensure that if one physical host fails, the virtual machines running on it can be automatically restarted on another host with minimal downtime. Which feature should they implement?

Accepted Answer

High availability. This question tests knowledge of high availability in virtualization. Fault tolerance keeps a VM running with zero downtime but requires more resources. Live migration moves VMs manually, and snapshots are for backup. High availability automatically restarts VMs on another host after a failure, providing a balance of cost and uptime.

Answer

Fault tolerance

Answer

Live migration

Answer

Snapshots

Question 9

A technician is investigating a security incident where a user's virtual machine was compromised. The technician suspects that the VM was infected with malware that spread from the host. Which virtualization security best practice would have prevented this?

Accepted Answer

Keep the hypervisor and host OS updated with security patches.. This question tests understanding of VM isolation and security. VM escape attacks allow malware to break out of a VM and infect the host. Using a Type 1 hypervisor reduces the attack surface, but the best prevention is to ensure proper isolation and keep the hypervisor updated. However, the question implies the infection spread from host to VM, which is the opposite; the correct answer focuses on preventing cross-VM infection. The most direct prevention is to use separate virtual switches and network segmentation, which is not listed. Among the options, keeping the hypervisor updated is the best general practice to prevent VM escape vulnerabilities.

Answer

Enable snapshots for all VMs.

Answer

Use a Type 2 hypervisor for better isolation.

Answer

Assign more virtual CPUs to the VM.
