AWS Exam is 135 minutes and 65 multilpe choices questions

 Deep Dives on Specific AWS Services

As mentioned above, the ACG course lectures alone are not enough for most people to pass. There are a few services that will come up on the exam a lot, and you will need a strong understanding of them in order to pass. The best way to learn what you need is to just use them with hands-on labs.

The areas to deep dive are as follows:

AWS VPC logo

AMAZON VPC

I struggled with an overall understanding of VPCs initially, and Cole Morrison’s article and its analogies helped immensely. I strongly suggest reading it if you are confused about VPCs. Also:

  • Complete the ACG Hands-on Labs for VPCs. These are outside of the course from step #2, in the Hands-on Lab section. Filter on “AWS” and “VPC” and complete each lab. They are only a few minutes apiece but are incredibly helpful.
  • The exam is very heavy in VPC questions. Learn to build one from memory.
  • Understand the differences between using a VPN and Direct Connect.

AWS S3 logo

AMAZON S3

Take parts of the A Cloud Guru S3 Masterclass course. You do not need to take this entire course for the exam, just a few areas that come up often, including:

  • Bucket policies vs. access control lists
  • S3 encryption options
  • Storage types
  • Lifecycle policies

AWS RDS logo

AMAZON RDS

Take the ACG Intro to RDS course, with a focus on areas that come up often, which include:

  • Multi-AZ Replication
  • Read Replicas
  • Understand snapshots


AWS Lambda logo

AMAZON LAMBDA AND SERVERLESS COMPONENTS

Take the ACG Intro to Lambda course but focus on:

  • Limits/timeouts
  • Events and what services are generally used with Lambda triggers

Serverless will probably show up more and more on AWS exams over time, so you’ll want to know this.
