Web アプリケーションの構築プロセスの一環として、コンプライアンス チームは、すべての PKI 証明書を毎年ローテーションし、セカンダリ サブドメイン レベルでのみワイルドカードを含めることを要求しています。これらの要件を満たす証明書プロパティは次のうちどれですか?
正解:C
Explanation This certificate property will meet the requirements because it has a wildcard at the secondary subdomain level (.app1.comptia.org), which means it can be used for any subdomain under app1.comptia.org, such as test.app1.comptia.org or dev.app1.comptia.org. It also has a validity period of less than one year, which means it will need to be rotated annually. The other options do not meet the requirements because they either have a wildcard at the primary domain level (.comptia.org), which is not allowed, or they have a validity period of more than one year, which is too long.
