Hello,
I have enrolled the CKAD certification e-learning course. I have troubles on setting up the VW instance. I get an error message asking for a subnetwork to be selected, but no subnetwork was set up...
Could you help me ?
Regards

    Hi @jolymakit,

    Thank you for the detailed screenshots. The VPC, Subnet, and Firewall rule appear to be correct. However, I was able to reproduce the error you are reporting.

    The error occurs because you may have omitted the Region and Zone selection, or selected an incorrect Region and Zone at the top of the New VM instance creation page. The selected VM Region has to match the VPC Subnet Region selected earlier. You may revisit the demo video from the introductory chapter for additional configuration details.

    Regards,
    -Chris

    This was moved to the LFD259 forum, to ensure it is looked at by the course moderators.

    Hi @jolymakit,

    What type of infrastructure are you configuring for labs? Any specific cloud provider or a local hypervisor?

    As it is explained in the CKAD e-learning video, I'm trying to configure an Ubuntu machine using a WM on GCE.

    The question is about the e-learning video that seems to be obsolete with GCE. If I don't get any answer, I'm going to ask for a refund.

    Hi @jolymakit,

    For Google Cloud on the "Create VPC network" page:

    1 - assign a desired name
    2 - scroll down to "Subnet creation mode"
    3 - select "Custom"
    4 - then click "ADD SUBNET"
    5 - assign a desired name
    6 - from the "Region" dropdown select a desired subnet region and fill in a desired "IPv4 range" as instructed in the video.
    Then continue to follow the instructions of the video guide.

    Please follow the video guides and later the pdf lab guide instructions as closely as possible to avoid any possible issues with the environment or the lab exercises.

    Regards,
    -Chris

    Hello chrispokorkni,
    Thanks for your reply, but this does not work. I'm getting the same error message.

    Hi @jolymakit,

    I attempted to reproduce the reported issue but so far I was not able to. I followed the GCE video and successfully created a VPC, defined a subnet, defined a firewall rule for the VPC, and eventually created a GCE VM in that VPC. None of the steps displayed errors.

    Please provide detailed screenshots of your VPC network details, such as the Overview and Subnets tabs, and the Firewalls tab expanded to show the ingress rule.

    Also, please provide a detailed screenshot of the subnet error message reported earlier.

    Regards,
    -Chris

    Hello @chrispokorni,
    You are write, the selected region on VPC and WM had to be the same.
    I can move on now.
    Thanks for your help.
