Single Answer
0What role does a subordinate CA have in a CA hierarchy?
Answer Options
A
Subordinate CAs issue certificates based on subdomains.
B
Subordinate CAs provide control over certificate issuance while avoiding the cost of being a root CA.
C
Subordinate CAs validate root CA activities to ensure auditability.
D
Subordinate CAs review certificate signing requests before forwarding them to the root CA.
Correct Answer: B
Explanation
Subordinate CAs avoid the cost of maintaining a root CA while providing control over certificates that are issued and allowing specialized support for different types of certificates like SSL and S/MIME. Subordinate CAs can issue certificates for any allowed domain or subdomain, are not required to ensure auditability, and can sign certificates themselves.
