Studying and passing the Oracle Cloud Infrastructure Foundations 2020 exam

A few pointers on my first Oracle Cloud certification

At any given point, I’m usually studying for a technical certification (or re-certification). I had some AWS certifications due for renewal in April 2020, but given the current COVID-19 lockdown, AWS kindly added 6 months to their validity, which meant the time pressure was off.

I’ve been working with Azure more and more over the past couple of years, so I had switched gears to studying for the AZ-300: Microsoft Azure Architect Technologies exam before it changes on 2 June 2020 and is retired later in the year.

Studying and passing the AWS DevOps Engineer Pro exam

I’m going to share a few pointers on my journey to studying for, and passing, the AWS DevOps Engineer Professional exam.

If the exam had been called, “AWS Solutions Architect - DevOps Professional”, I feel that would have been closer to what’s in the exam. The 80 questions were all mini-scenarios requiring a “solution”. In the exam blueprint, one of the bullet-points in “General IT Knowledge” was

Multi-tier architectures: load balancers, caching, web servers, application servers, databases, and networking

and these formed the basis of most scenarios, so ensure that you are comfortable with multi-tier architectures, particularly load balancers, database back-ends, what can be cached.
