A company has a data ingestion workflow that includes the following components:
* An Amazon Simple Notation Service (Amazon SNS) topic that receives notifications about new data deliveries
* An AWS Lambda function that processes and stores the data
The ingestion workflow occasionally fails because of network connectivity issues. When tenure occurs the corresponding data is not ingested unless the company manually reruns the job. What should a solutions architect do to ensure that all notifications are eventually processed?

C could work too, but I still prefer D for better control.

Increasing CPU/memory won't fix the connectivity issue, so B is a no-go.

Wait, can SNS really handle retries effectively? I'm not so sure.

Totally agree, D makes the most sense for reliability!

I think option D is the best choice here. SQS can handle failures better.

I'm a bit confused about whether modifying the Lambda's CPU and memory would actually solve the connectivity issue. It seems more like a performance tweak than a solution for failures.

I practiced a similar question where we had to handle message failures, and I think configuring the SNS retry strategy might be a good option too.

I think using SQS as a failure destination could help, but I need to double-check if that's the best approach for ensuring all messages are processed.

I remember studying about SNS and how it works with Lambda, but I'm not sure if just increasing retries is enough for network issues.

I think the answer is A. The question is asking what needs to be registered to receive chat messages, and the webhooks callback URL seems like the most logical choice for that.

I'm a bit confused by the options. Do I need to do something more than just share the app, like add a license or create a Flow? I want to make sure I fully understand the requirements.

Hmm, I'm a bit unsure about this one. I know the personal data protection acts in Hong Kong and Singapore were influenced by European regulations, but I'm not sure which specific safeguard was not included initially. I'll have to think this through carefully.
