350-601 Automation Practice Question
An engineer is designing an automation solution for a large data center with multiple Cisco UCS Manager domains. Which approach best ensures idempotent configuration operations?
⚠ Common exam trap
Cisco often tests the misconception that any API or script-based approach (like XML API or Python CLI) is automatically idempotent, when in fact only declarative tools with built-in state reconciliation (like Ansible) guarantee idempotency without additional custom logic.

Correct answer & explanation
✓
Using a declarative automation tool like Ansible with idempotent modules
Ansible's declarative modules for Cisco UCS Manager (e.g., `ucs_*` modules) are designed to be idempotent: they compare the current state of the configuration against the desired state defined in the playbook and only apply changes when necessary. This ensures that running the same playbook multiple times yields the same result without unintended side effects, which is critical for large-scale automation across multiple UCS domains.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Writing imperative Python scripts that execute CLI commands
Why it's wrong here
Imperative scripts may not be idempotent unless carefully designed.
- ✓
Using a declarative automation tool like Ansible with idempotent modules
Why this is correct
Declarative tools ensure the desired state is achieved regardless of current state.
- ✗
Directly calling UCS Manager XML API using POST requests
Why it's wrong here
Without state tracking, operations may not be idempotent.
- ✗
Using SNMP to set configuration parameters
Why it's wrong here
SNMP is not idempotent and not suitable for configuration.
