SSL Complete Guide 2021: HTTP to HTTPS - Certificate Domain Scopes

The video tutorial explains different types of certificate domain scopes: single domain, wild card, and multi domain. Single domain certificates are limited to one domain, while wild card certificates cover a domain and its subdomains. Multi domain certificates are valid for multiple domains and subdomains, with pricing increasing from single to multi domain. The tutorial also introduces TLS protocols, explaining how they secure data between computers and websites over HTTPS.

What is a characteristic of a single domain scope certificate?

• It can be used for multiple domains.

• It is the most expensive type of certificate.

• Its common name is usually equal to the domain.

• It is valid for all subdomains.

Which format is typically used for the common name in a wildcard certificate?

• star.domain.com

• domain.com

• www.domain.com

• star.dot.domain.com

Wildcard certificates are valid for:

• The main domain and all its subdomains

• Multiple unrelated domains

• Only subdomains

• Only the main domain

What is a feature of multi-domain certificates?

• They do not list domains in extensions.

• They are the cheapest type of certificate.

• They can cover multiple domains and subdomains.

• They are only valid for a single domain.

How does the cost of certificates generally change with scope?

• It increases from single domain to multi-domain.

• It remains the same regardless of scope.

• It is highest for wildcard certificates.

• It decreases from single domain to multi-domain.
