Question

A company wants to simplify the certificate management process. The company has a single domain with several dozen subdomains, all of which are publicly accessible on the internet. Which of the following BEST describes the type of certificate the company should implement?

A. Subject alternative name
B. Wildcard
C. Self-signed
D. Domain validation

Answer 1

The company should implement a b. Wildcard certificate to simplify the certificate management process for its single domain with several dozen subdomains.

Step-by-step explanation:

The type of certificate that the company should implement to simplify the certificate management process is a Wildcard certificate. A Wildcard certificate is a type of SSL/TLS certificate that can secure multiple subdomains of a single domain with a single certificate. In this case, the company has several dozen subdomains, so a Wildcard certificate would be the most suitable option as it can cover all subdomains with one certificate.

For example, if the company's main domain is 'example.com', a Wildcard certificate would secure 'subdomain1.example.com', 'subdomain2.example.com', 'subdomain3.example.com', and so on, without the need for separate certificates for each subdomain.

This simplifies the certificate management process as the company only needs to maintain and renew one certificate for all its subdomains.
