A cloud administrator has deployed several VM instances that are running the same applications on VDI nodes. Users are reporting that a role instance is looping between STARTED, INITIALIZING, BUSY, and STOP. Upon investigation, the cloud administrator can see the status changing every few minutes. Which of the following should be done to resolve the issue?
When a VM instance is repeatedly cycling between different states (STARTED, INITIALIZING, BUSY, and STOP), it usually indicates a problem with the application, its package, or the configuration files. Careful review and potential correction of the package and configuration files can identify and resolve errors or misconfigurations causing the VM instance to loop through these states. Therefore, the best course of action is to review the package and configuration file.
Can be B
C is the answer
The issue described, where a VM instance is repeatedly cycling between different states (STARTED, INITIALIZING, BUSY, and STOP), could be due to various factors. However, one common approach to address this issue and improve stability is to configure "service healing." Service healing is a feature in cloud environments that automatically detects and recovers from failures or issues with instances. It can involve actions like restarting the instance or replacing it with a new one when a failure is detected. By configuring service healing, you enable the cloud infrastructure to take corrective actions when it detects these kinds of issues, such as the repeated cycling of a VM instance. So, the answer is: C. Configure service healing. By configuring service healing, you allow the cloud environment to automatically handle the instance's state and attempt to recover it when it enters an undesirable state, improving overall system stability.
Agree w/ C and explanations.
I am going with C. Because B" Review the package" doesnt fix the issue. Reviewing does not resolve the issue.
his behavior suggests that there might be an issue with the application itself, its configuration, or its deployment package. By carefully reviewing the application's package and configuration files, you can identify potential errors, misconfigurations, or other issues that are causing the instance to continuously cycle through these states.

Problem: A role instance is looping between Started, Initializing, Busy, and Stopped This condition could indicate a problem with your application code, package, or configuration file. In that case, you should be able to see the status changing every few minutes and the Azure portal may say something like Recycling, Busy, or Initializing.
