I'm surprised the Lambda finishes in time but still times out!

I think CacheMissCount is less relevant here, though.

Wait, isn't CacheHitCount also important for performance?

IntegrationLatency and Latency are key metrics to check.

I feel like CacheMissCount might not be relevant for this timeout issue, but I could be wrong. I’d focus on IntegrationLatency and Latency instead.

I practiced a similar question, and I believe IntegrationLatency is definitely one of the metrics to check. The other one might be Latency, but I’m not completely confident.

I'm not entirely sure, but I remember something about CacheHitCount being useful for performance issues. Maybe it could help here?

I think we should look at IntegrationLatency and Latency metrics since they relate to how long the API Gateway takes to process requests.

I think the answer is A. A full mesh of iBGP peers is required to ensure proper route propagation inside a transit AS.

This question seems straightforward, but I want to make sure I understand the key terms like "presale activity" and "customer-focused sales plan" before answering.

I've got a good handle on this. The key is recognizing that JTWROS means "joint tenants with right of survivorship," so all the statements describe important aspects of how that type of account works.

I'm just hoping the issue isn't 'user error' on the developer's part. You know, like forgetting to adjust the Lambda timeout or something. Happens to the best of us, I suppose.

I'm going with B) IntegrationLatency and D) Latency as well. Gotta love it when the AWS docs are so clear and helpful, right? *sarcasm*

Definitely, those two metrics will be crucial in pinpointing the issue. I'm curious to see if the Lambda function is taking too long to process the requests, or if there's some other bottleneck in the API Gateway setup.

I think the correct answers are B) IntegrationLatency and D) Latency. These metrics will show us where the delay is happening, whether it's in the integration with the Lambda function or in the overall API Gateway response time.
