Solution: You configure an Azure Monitor alert to trigger the function.
Does this meet the goal?

  • A. No
  • B. Yes

NEW QUESTION # 31
You are troubleshooting the current issues caused by the application updates.
Which action can address the application updates issue without affecting the functionality of the application?

  • A. Enable time to live for the con-product container.
  • B. Set the default consistency level of account1 to bounded staleness.
  • C. Set the default consistency level of account1 to strong.
  • D. Add a custom indexing policy to the con-product container.

Answer: B

Explanation:
Explanation
Bounded staleness is frequently chosen by globally distributed applications that expect low write latencies but require total global order guarantee. Bounded staleness is great for applications featuring group collaboration and sharing, stock ticker, publish-subscribe/queueing etc.
Scenario: Application updates in con-product frequently cause HTTP status code 429 "Too many requests".
You discover that the 429 status code relates to excessive request unit (RU) consumption during the updates.
