Question 440
For the enterprise requirement "A global TCP service wants static public entry addresses and traffic steering over the AWS global network for lowest path latency", the team implemented this change: Configure Global Accelerator listeners and healthy regional ALB or NLB endpoints. What should operations verify instead of relying on configuration alone?
Explanation
Correct Answer
This measures the behavior required by the specific solution, rather than simply checking that it was configured. Global Accelerator accelerates supported TCP/UDP applications without serving as an HTTP content cache. The acceptance condition is linked directly to the scenario: A global TCP service wants static public entry addresses and traffic steering over the AWS global network for lowest path latency.
Incorrect Answers
The repeated key lookup hits DAX with lower latency while noncacheable paths use the underlying table. However, this does not establish the required outcome: clients use accelerator anycast addresses and connect to the healthy regional endpoint with improved path latency.
Free storage stays above emergency thresholds while capacity grows within policy rather than being oversized initially. However, this does not establish the required outcome: clients use accelerator anycast addresses and connect to the healthy regional endpoint with improved path latency.
Hot session lookups avoid repeated database queries and failure recovery preserves acceptable service behavior. However, this does not establish the required outcome: clients use accelerator anycast addresses and connect to the healthy regional endpoint with improved path latency.
