Security Fundamentals — Question 53

The certificate of a secure public Web server on the Internet should be:

Answer options

• A. Issued by a public certificate authority (CA)
• B. Signed by using a 4096-bit key
• C. Signed by using a 1024-bit key
• D. Issued by an enterprise certificate authority (CA)

Correct answer: A

Explanation

The correct answer is A because a secure public Web server needs a certificate issued by a public certificate authority to ensure trust from users. Options B and C discuss key lengths, which are important but do not address the requirement for public trust. Option D is incorrect as enterprise CAs are typically used for internal networks rather than public-facing services.
