Exam CV0-003 topic 1 question 289 discussion

The issue described suggests a misconfiguration or corrupted package in the deployed VM instances. The constant cycling between STARTED, INITIALIZING, BUSY, and STOP indicates that the application or service inside the VM is failing during startup due to a misconfigured or missing dependency.

The looping behavior (STARTED, INITIALIZING, BUSY, STOP) strongly suggests an issue with the application's startup or configuration. The instance is likely starting, attempting to initialize, encountering a problem (hence BUSY), and then stopping. This cycle repeats. The most likely cause is a misconfiguration within the application itself, either in the installation package or a configuration file. Service healing is a feature that automatically restarts failed services. While it might mask the symptom temporarily, it doesn't fix the cause of the repeated crashes. The application is already restarting (the STARTED part of the loop), so service healing is already happening. It's not solving the why.

Agree w/ C and explanations.

C is the answer

I am going with C. Because B" Review the package" doesnt fix the issue. Reviewing does not resolve the issue.

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.

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.
