Cisco Certified Support Technician (CCST) Cybersecurity

Network threats finally clicked for me. Passed on my first try.

The 100-160 is deceptively broad - it touches cryptography, wireless security threats, and security policies all at once. I underestimated it the first time and did not pass. Came back, focused on the weak spots with targeted practice, and cleared it on the second attempt.

Decent practice for the threat analysis and incident response sections. The cryptography questions could use a few more edge cases, but overall it helped me pass.

I used this to drill the CIA triad and access control concepts before my exam. Good coverage of the fundamentals Cisco tests on 100-160.

CCST Cyber made network security basics click for me.

The questions on firewall rules and network monitoring were tougher than I expected, but working through them here made the real exam feel manageable.
