Certification Strategy Tips
1. Align with Career Goals
Choose certifications that match where you want to be in 2-3 years, not just your current role.
2. Prioritize Hands-On Exams
Performance-based exams (RHCSA, CKA) carry more weight than multiple-choice tests.
3. Build a Certification Stack
Combine complementary certifications:
- Linux + AWS + Kubernetes = Cloud Engineer
- Security+ + CySA+ + Cloud = Security Analyst
- RHCSA + Terraform + CKA = DevOps Engineer
4. Consider ROI
Calculate the potential salary increase versus certification costs and study time.
5. Keep Certifications Current
Most certifications expire after 2-3 years. Plan for recertification.
