Now, a RHCSA certification would make me do linux administration on my sleep. But having a small lab over my spare laptop(I only have office laptop at this moment) would help me crack the job given I get till interview. However, a red hat cert will get me towards the interview.
My monthly saving is very low (Near about 80$) and I'd need 3-5 months of savings to afford a certification.
Oracle Linux is basically RHEL (rebranded) under the hood.
Could you practice your RHEL sysadmin skills on an Oracle Linux cloud VM?
