Your network contains an Active Directory domain named contoso.com. The domain contains a server named Server1 that runs Windows Server 2012 R2. 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. BIOS

B. Network Adapter

C. COM1

D. Processor

Explanation:

Named pipe.

This option connects the virtual serial port to a Windows named pipe on the host operating system or a computer on the network. A named pipe is a portion of

memory that can be used by one process to pass information to another process, so that the output of one is the input of the other. The second process can be local (on the same computer as the first) or remote (on a networked computer). For example, a loc

al named pipe path could be \\.\pipe\mypipename. Named pipes can be used to create a virtual null modem cable between two virtual machines, or between a virtual machine and a debugging program on the host operating system that supports the use of named pip

es.

By connecting two virtual serial ports to the same named pipe, you can create a virtual null modem cable connection. Named pipes are useful for debugging or for any program that requires a null modem connection.

Named pipes can be used to connect to a

virtual machine by configuring COM 1.
