200-901 Infrastructure and Automation Practice Question
A network team is implementing automation to provision new switchports across a campus network. They decide to use a controller-based approach with Cisco DNA Center. What is the primary advantage of using DNA Center for this task?
⚠ Common exam trap
Cisco often tests the distinction between intent-based automation (defining the desired state) versus traditional script-based automation (pushing explicit commands), and the trap here is confusing 'intent-based' with 'fully autonomous' or 'error-correcting' systems.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
It allows intent-based automation where the desired state is defined and the controller pushes the necessary configuration.
Cisco DNA Center uses an intent-based networking model where the administrator defines the desired state (e.g., 'provision a switchport for access VLAN 10') and the controller automatically translates that intent into the necessary device configurations (CLI or NETCONF/YANG). This abstraction reduces manual errors and enforces consistency across the campus network without requiring per-device CLI scripting.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
It automatically rolls back any configuration that deviates from the standard.
Why it's wrong here
Rollback is not automatic; it requires policy configuration.
- ✗
It replaces all existing CLI commands with a graphical interface.
Why it's wrong here
Not all CLI is replaced; some tasks still require CLI or API.
- ✓
It allows intent-based automation where the desired state is defined and the controller pushes the necessary configuration.
Why this is correct
Intent-based automation abstracts low-level configuration from the user.
- ✗
It eliminates the need for any human intervention in network management.
Why it's wrong here
Human intervention is still needed for oversight and exceptions.
