In PowerShell, which of the following is a feature that you use to assign a set of commands (optionally with input parameters) to execute by a single name?

In PowerShell, which of the following is a feature that you use to assign a set of commands (optionally with input parameters) to execute by a single name?

• subroutine
• procedure
• function
• method 

 

EXPLANATION

In PowerShell, functions can act like miniature scripts within scripts which are executed by name, and they can be everything from a few commands, to full blown cmdlets written entirely in PowerShell (called Advanced Functions).

about_Functions_Advanced on MSDN: https://msdn.microsoft.com/en-us/powershell/reference/4.0/microsoft.powershell.core/about/
Methods exist in PowerShell as well, as members of .NET objects: https://msdn.microsoft.com/en-us/powershell/reference/4.0/microsoft.powershell.core/about/about_meth...
Note: you can also access the above three directly in PowerShell with the commands:

Get-Help about_Functions
Get-Help about_Functions_Advanced
Get-Help about_Methods

Going beyond PowerShell, this is mostly a naming convention: the differences between the four names seem to vary from language to language.  While there are general technical definitions for each of the terms (for instance, "functions return a value; procedures do not"), these are not used universally among languages and programmers; as such, it's generally best to follow the naming convention common to the specific language.For more reading on the terms: http://softwareengineering.stackexchange.com/questions/20909/method-vs-function-vs-procedure

A hypervisor that runs directly on top of hardware (as opposed to on an OS) is known as:

• Side saddle
• Hosted
• Bare metal
• Type 2 

 

EXPLANATION

A bare-metal (also known as native or type-1) hypervisor runs directly on the host's hardware to control the hardware and to manage guest operating systems. For this reason, they are sometimes called bare-metal hypervisors.
A guest operating system runs as a process on the host.

Which benefit of being joined to a domain is not natively shared by Apple Macintosh computers?

Which benefit of being joined to a domain is not natively shared by Apple Macintosh computers?

• Group Policy
• Password Policy Enforcement
• Single Sign-On
• Windows Home Folders 

 

EXPLANATION

A domain-joined Mac workstation allows users to enjoy the following privileges:

• Kerberos authentication and delegation, including Single Sign-On to local, AD, and Open Directory resources
• AD password policy enforcement
• Support for AD user and group accounts
• Windows home folders

Of course, Mac computers do not have a Windows Registry and so therefore cannot be managed natively by Group Policy (the password policy issue previously mentioned is a notable exception).
