B- Wildcard SSL(Secure Sockets Layer) Certificate: Wildcard SSL certificates are for a single domain and all its subdomains.

Agree with B wildcard being the correct answer here

Answer: Wildcard - A wildcard certificate is an SSL certificate that can allow an unlimited amount of subdomains under a single domain be encrypted by the same certificate. ========================== Other Choices Subject Alternative Name - Lets you specify additional host names (sites, IP addresses, common names, etc.) to be protected by a single SSL Certificate. Self-Signed - A Self Signed certificate are public key certificates that users issue and sign themselves instead of from a publicly trusted Certificate Authority. These are useful for authenticating users on an internal network. Domain Validation - SSL certificates that requires only one validation setup between the person/organization applying for the certificate and a publicly trusted Certificate Authority who will confirm if they own the domain. Common methods for verification can be by email, file verification, or dns verification.

A Wildcard certificate is designed to secure a domain and all its subdomains with a single certificate. It is denoted by an asterisk () in the leftmost position of the domain name, such as ".example.com". This means that the certificate can be used to secure any subdomain under the main domain. In the case of the company with multiple subdomains, a Wildcard certificate would simplify the certificate management process. Instead of obtaining and managing individual certificates for each subdomain, a single Wildcard certificate can be used to secure them all. This reduces administrative overhead, simplifies the deployment process, and ensures consistent security across the domain and its subdomains.

The company should implement: B. Wildcard certificate. A Wildcard certificate is the best option for the company with a single domain and several dozen subdomains. It simplifies the certificate management process by securing not only the main domain but also all its subdomains with a single certificate. Here's how a Wildcard certificate works: 1. It is issued for a specific domain, such as ".example.com," where the asterisk () is a wildcard character that covers all subdomains of "example.com." 2. With a single Wildcard certificate, the company can secure any number of subdomains (e.g., mail.example.com, shop.example.com, blog.example.com, etc.) without needing separate certificates for each subdomain. 3. Wildcard certificates are especially beneficial when there are numerous subdomains to manage, as it significantly reduces the administrative overhead and simplifies the renewal and deployment processes. Therefore, a Wildcard certificate is the most appropriate choice for the company with a single domain and several dozen subdomains, providing a streamlined and efficient certificate management process.

The company should implement a wildcard certificate. A wildcard certificate is a type of digital certificate that can be used to secure multiple subdomains within a single domain. Wildcard certificates use the wildcard character (*) in the certificate's subject alternative name (SAN) field to match any subdomain within a given domain. This allows a single wildcard certificate to be used to secure all subdomains within the domain, simplifying the certificate management process. The company in this case has a single domain with several dozen subdomains, all of which are publicly accessible on the internet. Implementing a wildcard certificate would allow the company to secure all of its subdomains with a single certificate, simplifying the certificate management process.

A. Subject alternative name (SAN) certificate would be the best option for a company with a single domain and several dozen subdomains that are publicly accessible on the internet. SAN certificates allow a single certificate to be associated with multiple domain names, allowing the company to secure all of its subdomains with a single certificate, simplifying the certificate management process. A wildcard certificate would also be a valid option for a company with a single domain and several dozen subdomains that are publicly accessible on the internet. It allows a single certificate to be associated with all subdomains of a domain, making it easy to secure all the subdomains under one certificate. However, a Wildcard certificate would only work for subdomains and would not cover the main domain or any other domain that is not a subdomain of the main domain, in this case if the company wants to add any other domain in the future it would require another certificate.

In this case, the best option would be a Subject Alternative Name (SAN) certificate, also known as a Unified Communications Certificate (UCC). A SAN certificate can cover multiple domains, subdomains, and hostnames under a single certificate. This would allow the company to cover its main domain and all subdomains, as well as any future domains or subdomains that may be added. SAN certificates are commonly used in environments with multiple domains or subdomains.

Subdomains are covered by a domain in a Wildcard

with Wildcard the company can have many subdomains example : " *.company.com " => game.company.com , content.company.com , stock.company.com .

Example: SAN>: dns:www.acc-companyname.com, dns:www.tst-companyname.com (specific subdomains) Wildcard>: dns:www.*-companyname.com (*=numerous subdomains)

B-WILDCARD

wildcard certificate is the best for a company with a single domain and multiple subdomains

B. wildcard. wildcards are used as placeholders to match multiple subdomains or URLs within a specific domain. The wildcard character (*) is commonly used for this purpose.

The reason to choose option B is because the question mentions "single domain". SAN covers multiple domains (different domains) with a single cert. WildCard certificate supports multiple subdomains off of a single domain. Hence, the answer is B.

Wildcard: covers unlimited subdomains with a single Cert SAN: covers multiple domains names with a single Cert source: https://opensrs.com/blog/san-and-wildcard-certificates-whats-the-difference/

B. Wildcard. Helps with a main domain, with multiple subdomains on websites.
