What two software components are required on a Windows VM to apply a Customization Specification when cloning a virtual machine in vCenter?

What two software components are required on a Windows VM to apply a Customization Specification when cloning a virtual machine in vCenter?

• SysPrep and VMware Tools
• SysPrep and PERL
• VMware Tools and Java
• PERL and SysPrep 

EXPLANATION

SysPrep and VMware Tools are required by vSphere to make changes to the guest operating system. These changes usually include setting a NETBIOS name (host name), IP, and join a domain. This operation saves a lot of time for a vCenter administrator, especially when deploying large numbers of identical virtual machines.

• Exec 

EXPLANATION

Privileged EXEC mode is password protected, and allows the use of all EXEC mode commands available on the system. To enter privileged EXEC mode from user EXEC mode, use the enable command. Privileged EXEC mode allows access to global configuration mode through the use of the enable command. The privileged EXEC mode prompt consists of the devices's host name followed by the pound sign: Router# .

What is the smallest data unit in quantum computing?

What is the smallest data unit in quantum computing?

• 1 Cubik
• 1 Cubit
• 1 Qubit
• 1 Quanbit 

 

EXPLANATION

A qubit is a quantum bit , the counterpart in quantum computing to the binary digit orbit of classical computing. Just as a bit is the basic unit of information in a classical computer, a qubit is the basic unit of information in a quantum computer
In a quantum computer, a number of elemental particles such as electrons or photons can be used, with either their charge or polarization acting as a representation of 0 and 1. In a classical system, a bit would have to be in one state or the other. However, quantum mechanics allows the qubit to be in a superposition of both states at the same time, a property which is fundamental to quantum computing.
