Correct answer & explanation
✓
Amazon Route 53 private hosted zone
Amazon Route 53 private hosted zones allow DNS resolution for custom domain names (such as hostnames) within Amazon VPCs without requiring an external DNS service. Option A (Network Load Balancer) is incorrect because an NLB distributes incoming traffic across targets, it does not provide DNS resolution. Option B (Security Group rules) is incorrect because security groups act as virtual firewalls to control traffic, not DNS. Option C (VPC Peering) is incorrect because VPC peering connects networks at the IP level but does not offer hostname resolution. Option D is correct because a Route 53 private hosted zone is specifically designed for DNS resolution within VPCs, enabling hostname-based communication between SAP systems.
