Question
A company uses Amazon Route 53 to create a public DNS zone for the domain example.com in Account A. The company creates another public DNS zone for the subdomain dev.example.com in Account B. A security engineer creates a wildcard certificate (*.dev.example.com) with DNS validation by using AWS Certificate Manager (ACM). The security engineer validates that the corresponding CNAME records have been created in the zone for dev.example.com in Account B. After all these operations are completed, the certificate status is still pending validation. What should the security engineer do to resolve this issue?
