Hands-On Practice
- Set up a local Consul cluster with at least 3 servers to understand quorum and consensus
- Practice all CLI commands repeatedly until they become second nature
- Build a multi-service application using Consul service discovery and Connect
- Configure different health check types (HTTP, TCP, script) and observe their behavior
- Practice creating ACL policies for different scenarios (read-only, service-specific, admin)
- Set up a complete service mesh with intentions, routing, and traffic splitting
Understanding Architecture
- Draw architecture diagrams showing server/client relationships, gossip pools, and data flow
- Understand the difference between LAN gossip (within datacenter) and WAN gossip (between datacenters)
- Know the minimum and recommended number of Consul servers (3 or 5 for production)
- Study Raft consensus algorithm basics - leader election and log replication
- Understand when to use server vs. client agents and the tradeoffs
Security Deep Dive
- Master ACL policy syntax - practice writing policies for various access patterns
- Understand the ACL token types: management, client, agent, and their use cases
- Practice the ACL bootstrap process and initial token creation
- Know how to enable and configure gossip encryption with consul keygen
- Understand mTLS certificate lifecycle in Consul Connect
- Study the difference between default-allow and default-deny intention policies
Service Mesh Mastery
- Understand sidecar proxy injection and configuration
- Practice creating L7 traffic management with service routers, splitters, and resolvers
- Know the difference between ingress gateways, terminating gateways, and mesh gateways
- Study intention precedence rules when multiple intentions apply
- Understand how Consul integrates with Envoy as the default proxy
Exam-Specific Strategies
- The exam is 60 minutes for 57 questions - manage your time (about 1 minute per question)
- Questions are multiple choice and multiple select - read carefully for 'select all that apply'
- Focus heavily on practical scenarios rather than just theory
- Review the official exam objectives checklist multiple times
- Flag difficult questions and return to them - don't get stuck
- Pay attention to keywords like 'best practice', 'most secure', 'recommended'
- Understand the difference between Consul OSS and Enterprise features
Documentation Usage
- Bookmark key documentation sections: Architecture, CLI, API, ACLs, Connect
- While you can't use docs during exam, knowing where things are helps with studying
- Focus on the 'Use Cases' and 'How-To' sections in official docs
- Read the API documentation to understand programmatic interactions
- Study configuration file examples for agents, services, and checks
Common Pitfalls to Avoid
- Don't confuse Consul with other service mesh solutions (Istio, Linkerd) - know Consul-specific features
- Understand that health checks are evaluated by the agent where the service is registered
- Remember that intentions are enforced at the destination, not the source
- Know that default intentions are deny unless explicitly configured otherwise
- Understand that watches are triggered on state changes, not periodic polling
- Remember that prepared queries can provide failover and datacenter-aware routing
Exam Day Tips
- 1Arrive early or log in 15 minutes before your scheduled time
- 2Have a government-issued ID ready for verification
- 3Ensure your testing environment is quiet and well-lit (for online proctored exams)
- 4Read each question carefully - some ask for 'best' answer among multiple correct options
- 5Watch for questions asking about Consul Enterprise vs. OSS features
- 6Use the flag feature to mark questions you want to review
- 7Eliminate obviously wrong answers first in multiple-choice questions
- 8For 'select all that apply' questions, treat each option as true/false
- 9Don't overthink - your first instinct is often correct if you've studied well
- 10Keep track of time - aim to complete all questions with 10 minutes to review
- 11Stay calm and confident - the exam tests practical knowledge you've been practicing
- 12If unsure, think about what you would do in a real-world scenario
