AWS Certified CloudOps Engineer Associate SOA-C03 Practice Question

An e-commerce product API runs behind an ALB. Requests include a mandatory itemId query string plus optional marketing parameters, and the origin adds Cache-Control: max-age=300. The team introduces CloudFront to cut latency and origin load. They must cache objects uniquely per itemId, ignore all cookies, and treat other query strings identically, with minimal ongoing maintenance. Which CloudFront configuration satisfies these goals?

  • Attach a cache policy that includes only the itemId query string in the cache key and disables cookie forwarding.

  • Configure the distribution to forward all query strings and all cookies to the origin so CloudFront can cache every variant.

  • Deploy a Lambda@Edge viewer-request function that strips unwanted query strings and cookies, leaving the default cache behavior unchanged.

  • Enable forwarding of all query strings but whitelist the itemId parameter, and whitelist analytics cookies for origin forwarding.
