200-901 Infrastructure and Automation Practice Question
A developer wants to automate the configuration of multiple Cisco IOS-XE devices using Ansible. Which protocol should be used to ensure secure and idempotent configuration updates?
⚠ Common exam trap
Cisco often tests the distinction between protocols used for monitoring (SNMP) versus those used for secure configuration management (SSH), and candidates may mistakenly choose SNMP because they associate it with network management, overlooking that Ansible specifically requires an interactive, secure shell for idempotent configuration pushes.
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
✓
SSH
SSH (Secure Shell) is the correct protocol because it provides encrypted, authenticated remote access to Cisco IOS-XE devices, which is essential for secure automation. Ansible uses SSH to connect to network devices and execute configuration commands idempotently by comparing the desired state (defined in playbooks) against the current device state, ensuring only necessary changes are applied without duplication or disruption.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Telnet
Why it's wrong here
Telnet is insecure and not recommended for automation.
- ✓
SSH
Why this is correct
SSH provides secure, encrypted communication and is compatible with Ansible.
- ✗
SNMP
Why it's wrong here
SNMP is used for monitoring, not for idempotent configuration.
- ✗
HTTP
Why it's wrong here
HTTP is not typically used for device configuration and is insecure.
