You want to serve your website on both example.com and www.example.com using GCP App Engine with HTTPS. Which setup correctly achieves this with minimal manual DNS management?
AMap both domains; create TXT records for SSL; manually upload certificates
BMap only example.com in App Engine; create A record for www pointing to example.com IP; manually manage SSL
CMap both domains separately in App Engine and create CNAME for www pointing to ghs.googlehosted.com; use automatic SSL
DMap www.example.com only; create CNAME for example.com pointing to www; disable SSL
Step-by-Step Solution
Solution:
Step 1: Understand domain mapping for root and www
Both example.com and www.example.com need mapping to serve content on both URLs.
Step 2: Use recommended DNS and SSL setup
Google recommends CNAME for www to ghs.googlehosted.com and automatic SSL management for ease and security.
Final Answer:
Map both domains separately in App Engine and create CNAME for www pointing to ghs.googlehosted.com; use automatic SSL -> Option C
Quick Check:
Separate mapping + CNAME + auto SSL = best practice [OK]
Quick Trick:Map both domains and use CNAME for www with auto SSL [OK]
Common Mistakes:
Using A record for www which is not recommended
Mapping only one domain and missing the other
Disabling SSL or managing certificates manually unnecessarily
