The demand for knowledge is so high that you can skip help desk. This applies to every discipline within IT. You can skip help desk with a MCSA, CCNA, RHCSA, or Coding skills. At that point, I would pick the skill that is not as popular (Linux or Coding). Because that means less ppl know it. Which makes you more valuable.
Your resume must reflect the job you want. You could have all three certs, but if ur resume is created with help desk positions in mind. Those are the type of jobs you will get.
