When configuring role-based CLI on a Cisco router, which action will be taken first?

A.
Create a parser view called “root view.”

B.
Log in to the router as the root user.

C.
Enable role-based CLI globally on the router using the privileged EXEC mode Cisco IOS command.

D.
Enable the root view on the router.

Explanation:
Similar to making different commands available to different administrators using privilege levels, role-based
command-line interface (CLI) views can be used to provide different sets of configuration information to different
administrators. Following are the steps required to configure these views:

Step 1. Enable AAAto support views.
Example how to enable AAA on an IOS router:

Router# conf term
Router (config)# aaa new-model
Router (config)# end

Step 2. Enable the root view:
The root view is represented by the set of commands available to an administrator logged in with
a privilege level of 15. You might be required to provide the enable secret password to enable the
root view.
Example:

Router # enable view
Password:………
Router #

Step 3. Create a view

Step 4. Add available commands to the view: The commands parser_mode{include | include-exclusive | exclude} [all]
[interface interface_identifier | command] command

Step 5. Verify the role-based CLI view configuration
Therefore the actual first step to enable AAA which is missing here and the only option left is

D: enable root view.
