Exam PL-600 topic 1 question 2 discussion

I disagree. You wouldn't redirect to anywhere unless 4 failed and this question doesn't imply that it does. This was also on the MB-600 and the answer didn't include the on-premise. Not sure why you would. I'm going with. 2), 3), 4), 1)

2.The Applications makes a service call 3. The application receives an exception 4. The app automatically receives a call again 1. If second call is successful then app continues normally

2 3 4 1 2. The application makes a service call to the datacenter. (Initial step: The application attempts to communicate with the datacenter.) 3. The application receives an exception after attempting the service call. (If the call fails, an exception is raised.) 4. The application automatically tries the call again. (The application retries the operation as part of the retry process.) 1. If the second call is successful, the application continues normally. (Once successful, the system resumes normal operations.)

2-3-4-1 is right answer

The application makes a service call to the datacenter. If the application receives an exception after attempting the service call: The application automatically tries the call again. If the second call fails, the application redirects calls to an on-premises server.

Though on-premises system is not mentioned in description, I believe the answer is correct from solution design perspective. Since it is stated "any data loss creates a high risk", failed request to the cloud would not necessary be successful on a re-try. Hence, saving data to some on-premises system in these rare cases does make sense

2-3-4-1 is the correct answer

For me its 2-3-4-1

I agree with the proposed answer. Since the context is business continuity a (backup) on-premises data center makes sense.

redirecting to on-premises increases Business Continuity Risk. Best real-world answer is 2-3-4-1

I agree with Icky, there is no mention of a on-premises backup system. Answer should be, 2-3-4-1

Correct
