An orchestration workflow is creating a service that consists of a web server and a database. The web server needs the database's connection string, which is only available after the database is created. The workflow currently calls the database API and then the web server API. What is the most appropriate way to pass the connection string to the web server?

Hard-code the connection string in the web server API call

Capture the output of the database API call and pass it as input to the web server API call

Have the web server query the database for its own connection string

Create the web server first and then the database

When orchestrating the creation of a cloud service that includes a virtual network, a subnet, and a virtual machine, which sequence of API calls best reflects the dependency order in the N/E/S/W-bound model?

Create the virtual machine first, then the subnet, then the virtual network.

Create all three resources in parallel with no ordering.

Create the virtual network, then the subnet, then the virtual machine.

Create the subnet, then the virtual network, then the virtual machine.

An orchestration workflow is creating a new service that requires a database and an application server. The database must be created and initialized before the application server can connect to it. The workflow currently calls the database API and the application server API in parallel. What is the most appropriate way to fix the workflow?

Keep the parallel calls and add a retry loop in the application server

Remove the database API call and hard-code the database connection string

Add a dependency so the application server API call waits for the database API call to complete

Call the application server API first, then the database API
