You will need one head node, at least a dozen identical compute nodes, an Ethernet switch, a power distribution unit, and a rack. Determine the electrical demand, cooling and space required. Also decide on what IP address you want for your private networks, what to name the nodes, what software packages you want installed, and what technology you want to provide the parallel computing capabilities
Answer: D)It relies on two independent proofs of identity.
Explanation: Two factor authentication is technique which uses two steps/stage for the verification or authentication.It is done for the extra security maintenance.IT is also known as 2FA. It consist of two different authentication component so that it penetrates through double protection layer .
Other options are incorrect because It RSA public key cannot be used for the authentication of private content. It does not use both hand geometry at same time for both the levels and It does not utilize only single sign-on technology. Thus, the correct option is option(D).
This gap between user-designer communications <span>can cause a good project to go bad i</span>f the user is not able to process what is required to be fixed in order for the project to run smoothly. The user may have one way of fixing something while the designer has another. In this case, the designer understands how the project fully works while the user does not and this may end up compromising the whole project.
The law that “designers are not users” and “users are not designers” should always be followed.
