0

Hello,

I happy to share that I have achieved the AWS Solution Architect – Associate exam on 22-Oct-2019 and I would like to share my experience on achieving this certification.

I have no prior experience in any Cloud, and I started with AWS.

About the Exam:

  • Starts with Terms and condition page. On Agreeing you will get the popup that say the “First question will appear on clicking Next”
  • 65 questions
  • We can mark the question for Review, so that later you can review before the submit.
  • After 65 questions, you will have a survey questions (9 questions) asks about the testing environment.
  • Upon completing the exam, you will receive a pass or fail status on the screen.
  • As mentioned by other persons who took the exams, the questions where tricky.
  • Easy to eliminate 2 answers. Remaining 2 needs more focus. Read question one or more times, you can find some keyword in the question to choose the answer.
  • I marked only the questions which I feel my selection is wrong as Review.
  • During review, I choose different answers for 2 questions.

Sample Tricky question:

What to do a software update on the private instance which infra structure needs to be step up.

  1. NAT Gateway attached to Public Subnet and no need to have IGW attached to VPC.
  2. NAT Gateway attached to Public Subnet and IGW attached to VPC.
  3. VPC Direct Connect.
  4. VPC site-to site endpoint.

I know we need to use NAT Gateway for this scenario. But what confused me is whether Internet Gateway is mandatory for this scenario. The ans is yes we need to have IGW. Only the route needs to be configured to NAT Gateway which will use the IGW internally to route your traffic to internet.

Here are the few questions with Service and keywords which I have remembered after the exam.

  1. S3 used by the application, getting old data when access
  2. Kinesis – For processing IoT data in Sequence
  3. Dynamo DB – Frequently changing Schema
  4. Dynamo DB access from Lambda
  5. API gateway – Authentication using Cognito and IAM users

  13. Route 53 –
  14. ECS – Installing Docker Application
  15. Cold Storage – Need to store Infrequently used large volume of data from on premises to AWS EBS Storage. (No Glacier in the choice. Related to EBS Storage that needs to use)
  16. Throughput provisioned
  17. VPC Gateway endpoint – Private access to Dynamo DB without internet
