Palo Alto Networks System Engineer - Cortex Professional

The Cortex Data Lake architecture questions pushed me to actually understand the product, not just memorize terms. Worth the effort.

I hold several Palo Alto certs but PSE-CORTEX was the toughest to self-prepare for. The XSOAR automation and incident response sections demand genuine hands-on understanding - you cannot bluff your way through. NerdExam's practice questions surfaced gaps I did not know I had.

Still mid-study but the Cortex XDR investigation workflow questions are more applied than I expected. Good for building real confidence.

Cortex XDR concepts finally clicked. Passed on my first attempt.

Tough exam. The XSOAR playbook questions were no joke.

A few questions felt genuinely ambiguous, which mirrors the real exam experience more than I expected. The Cortex XPANSE attack surface management content was harder than the other domains for me. Still, working through the practice set gave me a much clearer map of where to focus.
