You have a server named Server1 that runs Windows Server 2012 R2.Server1 has the Print
and Document Services server role installed.

Server1 is connected to two identical print devices.
The solution must ensure that if one print device fails, the print jobs will print automatically on
the other print device.
What should you do on Server1?

A.
Add two printers and configure the priority of each printer.

B.
Install the Failover Clustering feature, and then add one printer.

C.
Install the Network Load Balancing (NLB) feature, and then add one printer.

D.
Add one printer and configure printer pooling.

Explanation:
By adding one printer as the default printer you ensure that only that printer is used at a
time, and creating a printing pool to automatically distribute print jobs to the next available
printer will cover all the requirements stated in the question. A printing pool is one logical
printer connected to multiple printers through multiple ports of the print server. The printer
that is idle receives the next document sent to the logical printer.
A printing pool is one logical printer connected to multiple printers through multiple ports of
the print server. The printer that is idle receives the next document sent to the logical printer.
This is useful in a network with a high volume of printing because it decreases the time users
wait for their documents. A printing pool also simplifies administration because multiple
printers can be managed from the same logical printer on a server.
