Exam SK0-005 topic 1 question 23 discussion

The correct answer is B

B. SSL You don't INSTALL PKI. Security in PKI is done with SSL certificates. SSL (Secure Sockets Layer) is the security protocol used on the web when you fetch a page whose address begins with https.

PKI = Public Key Infrastructure (Certificates) SSL = Secure Socket Layer (uses PKI certificates) to secure access by identifying a specific server/workstation/user. Look -real- carefully at what this question is asking...

I was going also for B, BUT than I realised that with PKI you can issue SSL. Now I am 65% sure than ansver is PKI as with it you can get both.

ChatGPT, when asked this exact question, went with SSL

When answering the question “what is PKI?” you need to talk not only about what it constitutes but also how it’s used. There are several ways that businesses and organizations around the world use public key infrastructure: There are several different types of digital certificates, which (you may notice correspond to the popular uses of PKI that we covered above). Here are some of the types of X.509 digital certificates that you can find within the PKI infrastructure: SSL/TLS certificates S/MIME certificates Code signing certificates Client authentication certificates In short, PKI includes much more than SSL, and is the more correct answer.

SSL cert

Answer is B. (tricky question) You must purchase/install a SSL cert. Along with it comes the PKI keys (Public Key Infrastructure). The PKI allows the message to be encrypted, but the SSL cert PROVES the site is who they claim to be (A.K.A TRUSTED..which the questions states is needed). https://www.thesslstore.com/blog/what-is-pki-a-crash-course-on-public-key-infrastructure-pki/

Web interface—this may also manage Linux servers. For example, Linux Cockpit allows you to display and manage your Linux servers via a web browser. Such administration is therefore relatively universal, since the administrator only has to be working from a device that can run a web browser. SSL VPN protocols may be used to secure the connection. The Official CompTIA Server+ Study Guide (Exam SK0-005) page 199. CompTIA Server+ Certification Exam Objectives EXAM NUMBER: SK0-005 never mentioned PKI, so the best answer is SSL.

A PKI certificate is a trusted digital identity. It is used to identify users, servers or things when communicating over untrusted networks, to sign code or documents and to encrypt data or communication. A PKI certificate is also called a digital certificate.

I agree Timock. This is referencing Certificates

You don't INSTALL PKI. Security in PKI is done with SSL certificates. SSL (Secure Sockets Layer) is the security protocol used on the web when you fetch a page whose address begins with https:. TLS (Transport Layer Security) is a newer version of the protocol. In practice, most websites now use the new version.
