Ask HN: Should all devops know how to fizzbuzz

I believe fizzbuzz (https://en.wikipedia.org/wiki/Fizz_buzz#Programming_interviews) should be dead simple to anyone who claims proficiency in coding or "scripting." Should it be a deal-breaker if a devops candidate struggles?

By devops I'm talking about someone who does things like automation (chef or puppet), cloud administration (AWS), configuring software (db, webserver), and troubleshooting some networking issues.
