Last Friday,your Organization Deployed a Brand New Server Core Installation

Multiple Choice

Last Friday,your organization deployed a brand new Server Core installation of Windows Server 2008.To simplify administrative tasks and to prevent downtime,your organization makes use of monitoring software that continually tests connectivity.This monitoring software then sends text messages to a specific group of administrators if it should detect that a server is unreachable for any reason.
On Monday,when the Server Core's IP address was placed into the monitoring software,the group of administrators received a text almost immediately telling them that the Server Core machine was unreachable.The administrator on-call says that on Friday,he was able to use the ping command successfully from the Server Core box to a well known internet address,as well as several servers on the local network.On Monday,he attempts to ping the Server Core installation from his workstation for the first time and does not receive a response.
Assuming that the Server Core installation is using default settings,what is most likely the issue?

A) Over the weekend,Windows Update ran and downloaded a driver update for the ethernet card without disabling the original driver,causing it to malfunction.Using the command waus.exe /purge /recent should fix the issue.
B) The Server Core machine has the TCP/IP protocol enabled on the outgoing protocol list for the configured network interface,but not for the incoming list.It must be added in the interface's Properties dialog box.
C) The network cable installed for the server has failed over the weekend,and should be replaced to restore normal network connectivity.
D) Windows Server 2008's firewall is blocking ICMP Echo Request packets by default.To fix the issue,you must type netsh firewall set icmpsetting 8
