GCP-ADP Data Pipeline Orchestration Practice Question
A Cloud Composer environment is experiencing high latency in the Airflow UI. What is a common cause and mitigation for this?
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
✓
Excessive DAG complexity; optimize/simplify DAG code.
High DAG count and complex dependency parsing can slow down the UI; using the 'DAG Serialization' feature (enabled by default in newer versions) helps, but optimizing DAG file size and complexity is the best mitigation.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Excessive DAG complexity; optimize/simplify DAG code.
Why this is correct
Complex DAGs increase parsing time, which impacts UI responsiveness.
- ✗
GKE node power failure; restart cluster.
Why it's wrong here
Composer is managed; infrastructure restarts are not manual tasks.
- ✗
Too many users logged in; force logout.
Why it's wrong here
User count has minimal impact on UI rendering compared to DAG parsing.
- ✗
Browser cache; clear your local cache.
Why it's wrong here
While possible, it is rarely the cause of high Airflow UI latency.
