CCAAK Mock Exams & Practice Exam Questions | Confluent Certified Administrator for Apache Kafka

Tip: Start with 15–25 question topic drills (replication/ISR, configs, security), then shift to mixed sets. Aim for consistent ~75–80% on mixed sets before scheduling.

Suggested progression

1. Topic drills (daily): 2× 15–25 questions focused on one topic from the Syllabus .
2. Mixed sets (alternate days): 1× 25–35 questions combining 2–3 topics.
3. Timed runs (final 1–2 weeks): 2–3 mixed runs under time; review every miss and re-drill weak objectives.

Exam snapshot (high level)

• Certification: Confluent Certified Administrator for Apache Kafka (CCAAK)
• Audience: platform/data engineers and SREs who operate Kafka clusters or support Kafka at scale
• Skills level: you should be comfortable reading configs, using CLI tools, and diagnosing common cluster states
• Official details: registration, pricing, and delivery mode can change—use the official links in Resources for the most current info.

Study funnel: Follow the Study Plan → work the Syllabus objective-by-objective → use the Cheatsheet for recall → validate with Practice .

What CCAAK measures (what you should be able to do)

1) Understand Kafka cluster architecture operationally

• Brokers, controllers, partitions, replication, and how failover looks from the outside.
• What ISR means, why it shrinks, and how durability settings interact (acks/min ISR).

2) Configure brokers and clusters safely

• Listener configuration, storage/log directories, networking settings, and performance basics.
• Making changes safely (rolling restarts, verification, and backout thinking).

3) Manage topics and data placement

• Partition count vs parallelism, replication factor choices, topic-level overrides.
• Partition reassignment and preferred leader election (conceptual + operational intent).

4) Apply security controls

• TLS basics, SASL authentication mechanisms (high level), and authorization with ACLs.
• Least privilege: what producers vs consumers vs admins need.

5) Monitor and troubleshoot

• Recognize unhealthy states (under-replicated partitions, offline partitions, controller churn).
• Diagnose lag, rebalances, timeouts, disk pressure, and misconfiguration.

6) Operate the Confluent ecosystem (awareness)

• Schema Registry, Kafka Connect, Control Center (or equivalent monitoring), and how they relate to cluster health.

Who should take CCAAK?

• Engineers responsible for Kafka reliability (availability, durability, performance, security)
• Teams supporting multiple producer/consumer applications and needing consistent governance
• Engineers preparing for more advanced streaming platform roles (capacity planning, multi-cluster patterns)

Readiness checklist

• I can explain ISR, replication factor, and why min.insync.replicas affects durability.
• I can choose a topic configuration for throughput vs durability and justify the trade-off.
• I can diagnose “under-replicated partitions” vs “offline partitions” and pick the next step.
• I understand consumer group scaling and why partitions cap parallelism.
• I can explain TLS vs SASL vs ACLs (encryption vs authn vs authz).
