Question

A public cloud provider recently updated one of its services to provide a new type of application load balancer. The cloud administrator is tasked with building out a proof-of-concept using this new service type. The administrator sets out to update the scripts and notices the cloud provider does not list the load balancer as an available option type for deploying this service. Which of the following is the MOST likely reason?

Options

  • AThe administrator can deploy the new load balancer via the cloud provider's web console.
  • BThe administrator needs to update the version of the CLI tool.
  • CThe administrator needs to write a new script function to call this service.
  • DThe administrator is not using the correct cloud provider account.

Why each option

The CLI tool does not list the new load balancer type because it is an older version that predates the cloud provider's service update.

AThe administrator can deploy the new load balancer via the cloud provider's web console.

The web console being available does not address why the CLI cannot enumerate the new service; the question is specifically about scripting and CLI support.

BThe administrator needs to update the version of the CLI tool.Correct

Cloud provider CLI tools are versioned software that must be updated to include API bindings for newly released services or service types. An outdated CLI version will not recognize the new application load balancer option, so upgrading the CLI tool adds support for the new service type and makes it available for scripting.

CThe administrator needs to write a new script function to call this service.

Writing a new script function is not the fix because the CLI tool itself lacks built-in support for the new service - updating the CLI resolves the issue without requiring custom function authoring.

DThe administrator is not using the correct cloud provider account.

The cloud provider account type does not determine which services the CLI tool can enumerate; the installed CLI version determines available service options.
