EX294 Coordinate rolling updates Practice Question
This EX294 practice question tests your understanding of coordinate rolling updates. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 OpenShift deployment is stuck in a degraded state after a rolling update. Which command helps diagnose the root cause by showing status conditions?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "which command"
Why it matters: Tests specific CLI syntax. Recall the exact command and its required context — near-synonyms and partial matches are common distractors.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
oc describe deployment/myapp
Option E is correct because `oc describe deployment/myapp` displays the full status conditions of the Deployment, including `Progressing`, `Available`, and `ReplicaFailure` conditions. When a rolling update leaves the Deployment in a degraded state, the `Conditions` field under `Status` explicitly shows the reason (e.g., `ProgressDeadlineExceeded` or `MinimumReplicasUnavailable`), which directly points to the root cause of the degradation.
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.
✗
oc rollout history
Why it's wrong here
Shows revision history but not current state conditions.
✗
oc get pods
Why it's wrong here
Shows pod status but not deployment conditions.
✗
oc logs deployment/myapp
Why it's wrong here
Logs a specific pod, not the deployment condition.
✗
oc get events
Why it's wrong here
Shows events but may not directly highlight the degradation.
✓
oc describe deployment/myapp
Why this is correct
Describes the deployment and shows status conditions like Progressing and Available.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often reach for `oc logs` or `oc get events` to debug failures, but the exam specifically tests whether you know that `oc describe` on the Deployment resource reveals the structured status conditions that define the degraded state.

Command / output trap
Shows revision history but not current state conditions.
Detailed technical explanation
How to think about this question
Under the hood, a Deployment controller manages a ReplicaSet and updates its status conditions via the `DeploymentStatus` struct, which includes fields like `Conditions` (an array of `DeploymentCondition` objects with `Type`, `Status`, `Reason`, and `Message`). During a rolling update, if the new ReplicaSet fails to become available within the `progressDeadlineSeconds` (default 600), the controller sets `Progressing` to `False` with reason `ProgressDeadlineExceeded`, causing the Deployment to be marked degraded. In real-world scenarios, this often occurs due to image pull errors, resource limits, or readiness probe failures, and `oc describe` surfaces the exact `Message` field to pinpoint the issue.

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.

What is the correct answer to this question?
The correct answer is: oc describe deployment/myapp — Option E is correct because `oc describe deployment/myapp` displays the full status conditions of the Deployment, including `Progressing`, `Available`, and `ReplicaFailure` conditions. When a rolling update leaves the Deployment in a degraded state, the `Conditions` field under `Status` explicitly shows the reason (e.g., `ProgressDeadlineExceeded` or `MinimumReplicasUnavailable`), which directly points to the root cause of the degradation.
