You need to ensure your personal SSH key works on every instance in your project. You want to accomplish this as efficiently as possible.

What should you do?

  1. Upload your public ssh key to the project Metadata.
  2. Upload your public ssh key to each instance Metadata.
  3. Create a custom Google Compute Engine image with your public ssh key embedded.
  4. Use gcloud compute ssh to automatically copy your public ssh key to the instance.

Answer(s): A

Explanation:

Overview By creating and managing SSH keys, you can let users access a Linux instance through third- party tools. An SSH key consists of the following files: A public SSH key file that is applied to instance- level metadata or project-wide metadata. A private SSH key file that the user stores on their local devices. If a user presents their private SSH key, they can use a third-party tool to connect to any instance that is configured with the matching public SSH key file, even if they aren't a member of your Google Cloud project. Therefore, you can control which instances a user can access by changing the public SSH key metadata for one or more instances. https://cloud.google.com/compute/docs/instances/adding-removing-ssh-keys#addkey



In order to provide subnet level isolation, you want to force instance-A in one subnet to route through a security appliance, called instance-B, in another subnet.

What should you do?

  1. Create a more specific route than the system-generated subnet route, pointing the next hop to instance-B with no tag.
  2. Create a more specific route than the system-generated subnet route, pointing the next hop to instance-B with a tag applied to instance-A.
  3. Delete the system-generated subnet route and create a specific route to instance-B with a tag applied to instance-A.
  4. Move instance-B to another VPC and, using multi-NIC, connect instance-B's interface to instance- A's network. Configure the appropriate routes to force traffic through to instance-A.

Answer(s): B
