EX294 Deploy Ansible Automation Platform Practice Question
This EX294 practice question tests your understanding of deploy ansible automation platform. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
An organization wants to deploy Ansible Automation Platform 2.x in a highly available configuration. Which component must be deployed in an active-active cluster to ensure controller failover?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Automation controller
The automation controller is the component that provides the web UI, REST API, and job execution management in Ansible Automation Platform 2.x. For high availability, multiple controller nodes must be deployed in an active-active cluster behind a load balancer, ensuring that if one controller fails, another can immediately take over without service interruption.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
PostgreSQL database
Why it's wrong here
The database is required for HA but is not the controller component itself.
✓
Automation controller
Why this is correct
The controller runs the web UI, API, and scheduler; an active-active cluster with a load balancer provides HA.

Read the scenario before looking for a memorised answer.
✗
Private Automation Hub
Why it's wrong here
Hub can be clustered for content management, but does not handle controller failover.
✗
Automation mesh
Why it's wrong here
Automation mesh distributes execution workloads, not controller failover.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse the automation mesh (which provides execution node redundancy) with the automation controller's active-active clustering, leading them to select mesh as the answer for controller failover.
Detailed technical explanation
How to think about this question
In an active-active controller cluster, each controller node runs its own instance of the Django-based web application and communicates with a shared PostgreSQL database. The load balancer distributes traffic using session persistence (e.g., cookie-based or source IP affinity) to maintain user sessions, and the controllers use a shared Redis cache for task queuing and session data. A real-world scenario is when a controller node crashes mid-job; the active-active setup allows the job to be re-queued or picked up by another node, but the job itself is not automatically migrated—this is a subtle behavior that distinguishes controller failover from execution node failover.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the EX294 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
