There are parallels between the trust models in Kerberos and Public Key Infrastructure (PKI). When we compare them side by side, Kerberos tickets correspond most closely to which of the following? a. private-key certificates.
b. private keys.
c. public-key certificates.
d. public keys.

c. public-key certificates.

Explanation:

It is important to note that in Kerberos infrastructure, tickets are issued by a third party as part of the authentication process.

This authentication process corresponds most closely to that of the Public Key certificates Infrastructure since it is a third party that issues out tickets to authenticate both parties engaged in the communication over a network.

there is no universally accepted definition of art. although commonly used to describe something of beauty, or a skill which produces an aesthetic result, there is no clear line in principle between (say) a unique piece of handmade sculpture, and a mass-produced but visually attractive item. we might say that art requires thought - some kind of creative impulse - but this raises more questions: for example, how much thought is required? if someone flings paint at a canvas, hoping by this action to create a work of art, does the result automatically constitute art?
