Exam 350-901 topic 1 question 225 discussion

C and E are correct.

truth be told, this is an extremely subjective question and pretty much any 2 are correct. To me, however, C and E are the ones that make more sense.

metrics plus logging

I asked ChatGPT and it answered A & C: I am highly confident in my answer. The two main considerations for implementing an observability-driven development lifecycle are choosing the appropriate monitoring tools and determining the relevant metrics to expose. Monitoring tools are necessary to collect and analyze data from the various components of the application, while relevant metrics provide insight into the application's behavior. The other options mentioned in the question are not directly related to an observability-driven development lifecycle but they could be important in other stages of the development or after the release.

C and D, from Cisco Study guide page 20: "Three pillars of observability are logs, metrics and tracing... Logs should provide as much information about application execution flow as possible..."

I think it's A and C as it's all about logging, monitoring and documentation. But it could be C and E. It's a tough call!!
