Question

Dion Training wants to reduce the management and administrative costs of using multiple digital certificates for all of their subdomains of ____. Which of the following solutions would allow the company to use one digital certificate for all of its subdomains?

1) OCSP
2) Key escrow
3) CRL
4) Wildcards

Answer 1

The solution is to use Wildcards.

Step-by-step explanation:

The solution that would allow Dion Training to use one digital certificate for all of its subdomains is Wildcards.

Wildcard certificates are used to secure multiple subdomains with a single certificate. They are issued for the parent domain and will cover all subdomains.

For example, if Dion Training has subdomains like www.diontraining.com, blog.diontraining.com, and mail.diontraining.com, a wildcard certificate for *.diontraining.com would cover all of these subdomains.
