Honestly, the clock caught me off guard more than the content did. The Network Security Administrator exam packs in a lot of scenario-based firewall configuration questions, and if you slow down trying to reason through each PAN-OS setup step by step, you burn minutes fast. I ended up spending too long on a handful of tricky policy and NAT questions early on, then had to rush through the rest.
What helped the second time around was doing timed practice runs instead of just reading material passively so that I could get a feel for pacing before the real thing. I used structured practice resources from CertBoosters alongside the official Palo Alto documentation to figure out which topics I was slow on versus which ones I actually didn't understand.
