Refer to the exhibit. How should the Jenkins job be troubleshooted based on the error provided?
Answer

Suggested Answer

The suggested answer is A.

The error message indicates that the file 'error_message.txt' was not found. This file is supposed to be created during the execution of the script if there are errors in any of the Python scripts being run. The troubleshooting step should be to verify what files are being created during the script execution and whether 'error_message.txt' is indeed being created or not. This will help in understanding why the file is missing and how to fix the job accordingly.

Question 7 of 161
Configuration changes to the production network devices are performed by a CI/CD pipeline. The code repository and the CI tool are running on separate servers.
Some configuration changes are pushed to the code repository, but the pipeline did not start.
Why did the pipeline fail to start?
Answer

Suggested Answer

The suggested answer is B.

The most likely reason for the pipeline failing to start is that the webhook call from the code repository did not reach the CI server. In a CI/CD pipeline, webhooks are typically used to trigger the CI server when changes are pushed to the code repository. If the webhook call fails to reach the CI server, the pipeline will not be triggered automatically.

Question 8 of 161
A new version of an application is being released by creating a separate instance of the application that is running the new code. Only a small portion of the user base will be directed to the new instance until that version has been proven stable. Which deployment strategy is this example of?
Answer

Suggested Answer

The suggested answer is D.

The deployment strategy described involves releasing a new version of an application by creating a separate instance and directing only a small portion of the user base to this new instance. This allows for testing and ensuring stability before fully rolling out the changes. This method is known as a canary deployment. The key feature of a canary deployment is the gradual exposure to the new version, minimizing risk and allowing for monitoring and validation.

Question 9 of 161
Which description of a canary deployment is true?
Answer

Suggested Answer

The suggested answer is D.

A canary deployment refers to deploying new software to a small, limited set of users or servers before rolling it out to the entire user base. This method helps in monitoring the new deployment in a real-world scenario and allows for the detection of any issues before the full-scale deployment. This reduces the risk of widespread problems.

Refer to the exhibit. What is causing the requests code to fail?
Answer

Suggested Answer

The suggested answer is B.

The error message 'NameError: name 'requests' is not defined' indicates that the 'requests' library is being used in the code, but it has not been imported. Python requires all libraries to be imported before they can be used. The correct approach is to import the 'requests' library at the beginning of the script, typically using the line 'import requests'.
