Full question →mediummultiple choiceObjective-mapped
A company hosts its customer relationship management (CRM) application on a single virtual machine (VM) in a public cloud. The VM is configured with a static private IP address that is used by a third-party service to send data to the application. During a scheduled hardware maintenance event, the cloud provider automatically migrates the VM to a different physical host. After the migration, the CRM application can no longer receive data from the third-party service. Which of the following cloud computing concepts was MOST likely not properly implemented?
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
Distractor review
Elasticity
Elasticity refers to the ability to automatically scale resources up or down based on demand. It does not affect IP address assignment during host migration.
B
Best answer
High availability
High availability is the characteristic that ensures a service remains accessible despite component failures. In this case, the VM was automatically restarted on another host (HA was working), but the static IP was not preserved. To prevent this, a floating IP or elastic IP should have been reserved, which is an important consideration when implementing HA.
C
Distractor review
Scalability
Scalability is the ability to increase the size or capacity of a resource to handle growth. It does not relate to IP address retention after migration.
D
Distractor review
Resource pooling
Resource pooling allows the cloud provider to serve multiple customers from shared physical resources. While it enables migration, the loss of IP address is not a direct consequence of pooling but rather of not reserving the IP address.
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: High availability — The VM was automatically moved to another host, indicating that high availability (HA) was configured. However, the VM lost its static IP address, which is a common issue when HA is implemented without also reserving the IP address (using a floating IP or elastic IP). In many cloud environments, a VM's IP address can change when it is restarted on a different host unless the IP is explicitly reserved. High availability alone does not guarantee IP persistence. Elasticity, scalability, and resource pooling do not directly address IP address assignment after migration.
