350-601 Automation Practice Question
A financial services company operates a multi-site data center with Cisco ACI. The automation team uses Ansible Tower to manage configurations. They have a playbook that configures EPGs using the 'aci_epg' module. The playbook runs successfully for most sites but fails on one site with the error 'Object 'uni/tn-Tenant1/ap-AP1/epg-EPG1' doesn't exist'. The engineer checks the ACI fabric and confirms that the tenant, application profile, and EPG exist on that site. The playbook uses the same credentials and variables across all sites. What is the most likely cause of the failure?
⚠ Common exam trap
Cisco often tests the concept that Ansible inventory variables (like fabric hostname or APIC IP) must match the target site, and candidates mistakenly focus on credentials or module syntax instead of verifying the inventory configuration for each site.
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
✓
The fabric name in the Ansible inventory is incorrect for that site
The error 'Object doesn't exist' despite the EPG being present on the ACI fabric indicates that Ansible is targeting the wrong fabric or APIC. Since the playbook uses the same credentials and variables across all sites, the most likely cause is an incorrect fabric name in the Ansible inventory for that specific site, causing the module to query a different APIC cluster where the object does not exist.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The Ansible Tower job runs with a different user that lacks permissions on that site
Why it's wrong here
Permission errors would show as authorization failure, not object not found.
- ✗
The ACI APIC version is incompatible with the Ansible module
Why it's wrong here
Would cause failures across all sites, not just one.
- ✗
The EPG name in the playbook has a typo that only affects this site
Why it's wrong here
A typo would affect all sites using that variable.
- ✓
The fabric name in the Ansible inventory is incorrect for that site
Why this is correct
Leads to connection to wrong APIC where EPG doesn't exist.
