The correct answer is B. Version of API on the public cloud. The inability to deploy new VMs using an unchanged orchestration tool, while other deployments work and resources are available, strongly suggests an incompatibility with the cloud provider's API.
Question
A company uses a public IaaS. Company engineers use an orchestration tool to deploy VMs. The orchestration tool was configured a year ago and worked well. Now, however, the company cannot deploy new VMs. Given the information below:
- No one changed the configuration of the orchestration tool.
- Other deployments (e.g., network, storage) are working on the orchestration tool.
- There are enough resources assigned for the company.
Which of the following is the cause of this issue?
Options
- AUser account expiration
- BVersion of API on the public cloud
- CLack of IP addresses
- DNetwork connection issues

Why each option
The inability to deploy new VMs using an unchanged orchestration tool, while other deployments work and resources are available, strongly suggests an incompatibility with the cloud provider's API.
If a user account expired, all deployments using that account would likely fail, not just VM deployments.
Cloud providers regularly update their APIs, and an orchestration tool configured a year ago might be using an older API version that has been deprecated or changed in a breaking way, preventing new VM deployments while other, potentially simpler or different, deployments still function.
The question explicitly states that there are enough resources assigned for the company, which would include IP addresses.
Network connection issues would likely cause all deployments and interactions with the cloud provider via the orchestration tool to fail, not just VM deployments.
