Which virtual machine setting should you configure?

Your network contains an Active Directory domain named contoso.com. The domain contains a server named
Server1 that runs Windows Server 2012. Server1 has the Hyper- V server role installed. The domain contains a
virtual machine named VM1.
A developer wants to attach a debugger to VM1.
You need to ensure that the developer can connect to VM1 by using a named pipe.
Which virtual machine setting should you configure?

A.
Network Adapter

B.
BIOS

C.
Processor

D.
COM 1

Explanation:
Named pipe. This option connects the virtual serialport to a Windows named pipe on the host operatingsystem
or a computer on the network. A named pipe is a portion of memory that can be used by one processto pass
information to another process, so that the output of one is the input of the other. The second processcan be
local (on the same computer as the first) or remote(on a networked computer). For example, a localnamed
pipe path could be \\.\pipe\mypipename.
Named pipes can be used to create a virtual null modem cable between two virtual machines, or between
avirtual machine and a debugging program on the host operating system that supports the use of named pipes.
By connecting two virtual serial ports to the same named pipe, you can create a virtual null modem
cableconnection. Named pipes are useful for debugging or for any program that requires a null modem
connection.
