DVA - Extra Notes

Exam Tips

  • There are very very few trick questions
  • If a solution seems feasible but highly complicated, it's probably wrong
  • Whenever there is a negative keyword like NOT then the chances of the option being the correct answer is very less.
  • Whenever you have questions related to debugging why something is not working then options containing the word permissions becomes a potential answer.
  • When you see automatic retries think about AWS SDK.
    • AWS SDK also implements exponential backoff.
  • If you need to figure out why some service is slow (performance issues) just go with X-Ray.
  • Generally when something is wrong in the application configuration it will give us a big error.
