In PowerShell, all of the following are valid ways to create an array, except:

In PowerShell, all of the following are valid ways to create an array, except:

• $array = %('this, 'that')
• $array = @('this', 'that')
• $array = ('this', 'that')
• $array = [array]('this', 'that') 

EXPLANATION

In programming, arrays are collections of items.  In PowerShell, these items are always objects, and a single array can contain different, unrelated object types.
Typically, simply putting a comma between different items causes them to be treated together like an array.  You can also explicitly declare an array with the [array] type marker, or with the shorthand "@" symbol.
In PowerShell, the "%" symbol is an alias for "Foreach-Object", and the example above will throw an error.
Fun fact: in Perl, the "%" is used to declare a variable as a hashtable, which is similar to an array, but uses a named key index instead of an automatic number index; unlike in PowerShell, the variable prefix in Perl actually changes depending on use, so a hashtable variable would look like "%variable" instead of "$variable".

Which of the following is NOT a feature of the Microsoft Exchange 2016 Transport Pipeline?

Which of the following is NOT a feature of the Microsoft Exchange 2016 Transport Pipeline?

• Transport service
• Mailbox transport
• Back end transport service
• Front end transport service 

 

EXPLANATION

The Microsoft Exchange Transport Pipeline uses the following services:

• Front end transport service, which does basic message filtering based on domains, connectors, senders and recipients. It only connects with the transport service on a mailbox server and does not backlog any messages locally
• Transport service, which runs on all mailbox servers, and handles SMTP mail flow. It helps in message categorization and content inspection. The transport services routes messages between the Mailbox Transport service, the Transport Service and Front End Transport service.  This service does not queue messages locally
• Mailbox Transport, which handles receiving and sending SMTP to the transport service from the mailbox using remote procedures calls (RPCs).
