A. Yes! A wildcard certificate can be applied to a single domain with multiple subdomains, for example mail.domain.com, secure.domain.com, and sub.domain.com can all have the single SSL Certificate. With a wildcard SSL you can secure all these subdomains by simply securing *.domain.com, securing any subdomain you can think of. Learn how to create a wildcard CSR to start securing your domains.
