OS Login is a Google-recommended practice for managing access to Linux VMs in Compute Engine. It centralizes user account management by linking the Linux user accounts on the VMs to Google Cloud identities. You then use IAM roles to grant users the necessary permissions to access the VMs (e.g., roles/compute.osLogin or roles/compute.osAdminLogin). This simplifies management as you control access through IAM policies rather than managing individual SSH keys on each VM, thus minimizing operational costs.

Option B: While enabling OS Login is a good first step, writing custom startup scripts to manage user permissions adds complexity and operational overhead, contradicting the goal of simplification and minimizing costs.

Option C: Requiring developers to manage their own SSH keys and making the owner root is a significant security risk and not a recommended practice. It also doesn't centralize management.

Option D: This approach also involves managing individual SSH keys and custom scripts, which increases operational overhead and doesn't leverage the centralized management benefits of OS Login.

OS Login and its benefits for simplified and secure Linux VM access management are detailed in the Compute Engine documentation, which is a key area for the Associate Cloud Engineer certification. The integration with IAM for permission control is a central aspect of this service.

Creating and starting a preemptible VM instance This page explains how to create and use a preemptible virtual machine (VM) instance. A preemptible instance is an instance you can create and run at a much lower price than normal instances. However, Compute Engine might terminate (preempt) these instances if it requires access to those resources for other tasks. Preemptible instances will always terminate after 24 hours. To learn more about preemptible instances, read the preemptible instances documentation. Preemptible instances are recommended only for fault-tolerant applications that can withstand instance preemptions. Make sure your application can handle preemptions before you decide to create a preemptible instance. To understand the risks and value of preemptible instances, read the preemptible instances documentation.https://cloud.google.com/compute/docs/instances/create-start-preemptible-instance

Cloud Run takes any container images and pairs great with the container ecosystem: Cloud Build, Artifact Registry, Docker. ... No infrastructure to manage: once deployed, Cloud Run manages your services so you can sleep well. Fast autoscaling. Cloud Run automatically scales up or down from zero to N depending on traffic.

Given that the new instance wants to access the application on the existing compute engine instance, these applications seem to be related so they should be within the same VPC. It is possible to have them in different VPCs and peer the VPCs but this is a lot of additional work and we can simplify this by choosing the option below (which is the answer)

1. Create a subnet in the same VPC, in europe-west1.

2. Create the new instance in the new subnet and use the first instance subnets private address as the endpoint. is the right answer.

We can create another subnet in the same VPC and this subnet is located in europe-west1. We can then spin up a new instance in this subnet. We also have to set up a firewall rule to allow communication between the two subnets. All instances in the two subnets with the same VPC can communicate through the internal IP Address

For a web application (typically using HTTP/HTTPS), an Application Load Balancer is the recommended choice as it operates at Layer 7, providing features like content-based routing, SSL termination, and improved security. To expose the application publicly, you would need to use a public DNS zone. An A record in a public DNS zone maps a domain name to the public IP address of the Application Load Balancer. Using a CNAME record would also work but is generally recommended for aliasing one domain name to another, not directly to an IP address.

Option A & B: Network Load Balancers operate at Layer 4 (TCP/UDP) and lack the application-level features of an Application Load Balancer. Private DNS zones are for internal name resolution within your VPC, not for public access.

Option C: While an Application Load Balancer is the correct type, using a private DNS zone wouldn't make the web application publicly accessible.

The best practices for load balancing web applications on Google Cloud, including the use of Application Load Balancers for Layer 7 traffic and the configuration of public DNS records (A or CNAME) for public access, are detailed in the Google Cloud Load Balancing and Cloud DNS documentation, both important for the Associate Cloud Engineer certification.
