You have deployed a three-tier web application inside an Oracle Cloud Infrastructure (OCI) VCN with a CIDR block of 10.0.0.0/28. You Initially deploy three web servers (VM.Standard2.2), two application servers (VM.Standard2.4), and two servers (VM.Standard2.8) running Oracle database.
The web, application and database servers are deployed across two availability domains in the us-ashburn-1 region.
You also deployed a Public Load Balancer In front of the two web servers. The web traffic gradually Increases In the first few days following the deployment, so you attempt to double the number of instances in each tier of the application to handle the new load. Unfortunately, some of these new Instances fail to launch.
Your tenancy comes with the following set of predefined services limits for the availability domain and compartment where the applicationis deployed.

What is a possible reason for this deployment to fail?
