Google Certified Cloud Engineer Associate Practice Exam 102

Based on the information provided, the correct answer to the question regarding changing the machine type for srv-bizdev from n1-standard-4 to n1-standard-8 with 6 vCPU is:

(A) Stop srv-bizdev, edit this server properties, click on customize, change the slider to 6 vCPU.

This action allows you to use the customization feature in Google Cloud Platform's Compute Engine to modify the machine type after deployment. You can't change the number of vCPU directly through the GUI if the exact pre-defined machine type isn't available, but you can stop the VM, go into the customize tab, and then adjust the slider for CPU options, which will allow you to specify exactly the resources you need, including the number of vCPU. This feature is particularly useful when a pre-defined machine type doesn't match your requirements precisely.

Please note that as of my knowledge cutoff in 2023, Google Cloud Platform has introduced new VM machine types, and the ability to customize VMs at runtime may vary based on the specific machine type and region. Always refer to the latest Google Cloud documentation or their support for the most current information and capabilities.
