70-687 Configuring Windows 8.1 – sample exam – Q78

A company has 10 portable client computers that run Windows 8.1.
The portable client computers have the network connections described in the following table.
78-q
None of the computers can discover other computers or devices, regardless of which connection they use.
You need to configure the connections so that the computers can discover other computers or devices only while connected to the CorpWired or CorpWifi connections.
What should you do on the client computers?

A. For the CorpWired connection, select yes, turn on sharing and connect to devices.
B. Change the CorpWired connection to public. Turn on network discovery for the Public profile. For the HotSpot connection, select No, don’t turn on sharing or connect to devices.
C. For the CorpWifi connection, select yes, turn on sharing and connect to devices.
D. Turn on network discovery for the Public profile.
E. Turn on network discovery for the Private profile.


Correct Answer: B

The CorpWifi and HotSpot connections are already set properly. The private profile has network discovery enabled by default. So we need to deal with the CorpWired without breaking anything else. CorpWired connection is already public so it doesn’t make sense to set it again to public. Also, enabling network discovery for the Public profile is a dangerous practice. Ideally it would be to set the CorpWired connection to private. However, since this is not one of the avail- able options, turning on sharing basically does the same thing.

Simple Questions: What are Network Locations in Windows 7 & Windows 8?

Network Locations in Windows 8: Private vs Public
Windows 8 further simplifies the concept of network locations, reducing them to only two choices:
Private network – This profile should be applied to your home network or to the network from your work- place. When this profile is assigned to a network connection, network discovery is turned on, file and printer sharing are turned on and homegroup connections are allowed. Public network – This profile is also named Guest. It is the more secure of the two because network dis- covery is turned off as well as file and printer sharing. This profile should be used when connecting to public networks you don’t trust, like those found in airports, coffee shops, bars, hotels, etc. There’s also a third network location profile named Domain network. This one cannot be set by a normal user. It is available for enterprise workplaces and it is set by the network administrator. The settings ap- plied to this profile are those set by your company and you cannot change them.

Selecting “No, don’t turn on sharing or connect to devices” is the equivalent of applying the Public profile. Selecting “Yes, turn on sharing and connect to devices” is the equivalent of applying the Private profile.

Make your choice and the appropriate settings are applied.
