Question 1mediummultiple choice
Full question →mediummultiple choiceObjective-mapped
A company uses a cloud service where administrators can provision virtual machines with pre-configured operating systems and applications from a catalog. They can scale the number of VMs up or down as needed, but they are responsible for managing the guest OS and applications. Which cloud service model does this describe?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Best answer
Infrastructure as a Service (IaaS)
IaaS delivers virtualized hardware (servers, storage, networking) on demand. Customers provision VMs with custom OS and applications, and are responsible for managing them.
B
Distractor review
Platform as a Service (PaaS)
PaaS provides a platform for developing and running applications without managing the underlying infrastructure. Users do not provision full VMs or have direct control over the OS.
C
Distractor review
Software as a Service (SaaS)
SaaS delivers fully functional applications over the internet. The provider handles everything, and users do not manage VMs or OS.
D
Distractor review
Desktop as a Service (DaaS)
DaaS provides virtual desktop environments, not general-purpose VMs that can be customized with any OS and applications.
Common exam trap
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Technical deep dive
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.

Question 1
A user reports intermittent network connectivity on a desktop computer. The technician observes that the Ethernet link light on the NIC turns off for a few seconds and then turns back on. The cable passes a wiremap test, the switch port is verified good with another device, and the NIC driver is updated. The issue occurs more frequently when the computer's case fan runs at high speed. Which of the following is the MOST likely cause?
Question 2
A workstation is unable to connect to the internet. The technician runs the 'ipconfig' command and sees the IPv4 address is 169.254.15.200 with a subnet mask of 255.255.0.0. The workstation can ping other devices on the local subnet but cannot ping the default gateway or any external addresses. Which TWO actions should the technician take to resolve this issue? (Select two.)
Question 3
A workstation is connected to a managed switch. It obtains a valid IP address (192.168.10.50) from the DHCP server, but it cannot ping the default gateway (192.168.10.1). The link light on both the workstation NIC and the switch port are solid green. Other workstations on the same switch CAN ping the default gateway successfully. The technician accesses the switch management interface and finds that the workstation's port is configured as an access port on VLAN 10. The default gateway is located on VLAN 20. An inter-VLAN router is configured but not explicitly allowing VLAN 10 access to VLAN 20. Which of the following is the MOST likely cause of the problem?
Question 4
A company develops a web application that relies on a custom library available only for a specific Linux distribution. They want to deploy the application in the cloud with minimal administrative overhead, but they need full control over the software stack, including the ability to install the custom library and configure the web server. Which cloud service model BEST meets these requirements?
Question 5
A company has a legacy virtual machine running on a deprecated hypervisor (Hyper-V). They want to migrate this VM to a new hypervisor (VMware vSphere) hosted in a private cloud while preserving the VM's configuration, installed applications, and data. The migration must be performed with minimal downtime. Which of the following methods is MOST appropriate?
Question 6
A company hosts a critical database on a virtual machine in a public cloud. The database requires persistent storage that must be retained even if the VM is terminated. The storage must also be accessible from multiple VMs simultaneously for a future high-availability configuration. Which type of cloud storage BEST meets these requirements?
FAQ
Questions learners often ask
What does this 220-1101 question test?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: Infrastructure as a Service (IaaS) — Infrastructure as a Service (IaaS) provides virtualized computing resources (like VMs) over the internet. The cloud provider manages the physical hardware and virtualization layer, while the customer is responsible for the guest OS, middleware, and applications. This matches the scenario where administrators can provision VMs from a catalog and manage the OS and apps themselves. Platform as a Service (PaaS) abstracts the OS and provides a runtime environment for applications, not full VMs. Software as a Service (SaaS) provides fully managed applications. Desktop as a Service (DaaS) provides virtual desktops, not general-purpose VMs.
