Answer choices

Why each option matters

Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.

A

Distractor review

Lambda reserved concurrency set to zero

Reserved concurrency of zero stops processing and does not preserve failed events as an error-handling strategy.

B

Best answer

A Lambda dead-letter queue or failure destination

A DLQ or asynchronous failure destination captures failed events after retry attempts.

C

Distractor review

A larger deployment package

Package size does not affect failed-event capture.

D

Distractor review

CloudFront error pages

CloudFront does not manage Lambda asynchronous retry failures.

Common exam trap

Common exam trap: NAT rules depend on direction and matching traffic

NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.

Technical deep dive

How to think about this question

NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.

KKey Concepts to Remember

  • Static NAT maps one inside address to one outside address.
  • PAT allows many inside hosts to share one public address using ports.
  • Inside local and inside global describe the private and translated addresses.
  • NAT ACLs identify traffic for translation, not always security filtering.

TExam Day Tips

  • Identify inside and outside interfaces first.
  • Check whether the scenario needs static NAT, dynamic NAT or PAT.
  • Do not confuse NAT matching ACLs with normal packet-filtering intent.
