Your network is configured as shown in the exhibit. (Click the Exhibit button.)
Server1 regularly accesses Server2.
You discover that all of the connections from Server1 to Server2 are routed through Router1.
You need to optimize the connection path from Server1 to Server2.
Which route command should you run on Server1?
A.
Route add -p 10.10.10.0 MASK 255.255.255.0 172.23.16.2 METRIC 100
B.
Route add -p 10.10.10.0 MASK 255.255.255.0 10.10.10.1 METRIC 50
C.
Route add -p 10.10.10.12 MASK 255.255.255.0 10.10.10.1 METRIC 100
D.
Route add -p 10.10.10.12 MASK 255.255.255.0 10.10.10.0 METRIC 50
Explanation:
Destination – specifies either an IP address or host name for the network or host.
subnetmask – specifies a subnet mask to be associated with this route entry. If subnetmask is not
specified, 255.255.255.255 is used.
gateway – specifies either an IP address or host name for the gateway or router to use when
forwarding.
costmetric – assigns an integer cost metric (ranging from 1 through 9,999) to be used in calculating
the fastest, most reliable, and/or least expensive routes. If costmetric is not specified, 1 is used.
interface – specifies the interface to be used for the route that uses the interface number. If an
interface is not specified, the interface to be used for the route is determined from the gateway IP
address.

Wrong. The given answer will forward all trafic to the 172.23.16.0/24 network to router 2.
Correct answer is C!
Not C, just looked at the IP.
correct would be:
Route add -p 10.10.10.12 MASK 255.255.255.255 172.23.16.2 METRIC 100
This is the answer to: “You need to optimize the connection path from Server1 to Server2”.
Why would the GW be 255.255.255.255 instead of 255.255.255.0?
A is the correct answer.
This will set the default gateway for all traffic to 10.10.10.0/24 to 172.23.16.2.
As a side note, 10.0.0.0/8 is a private IP range which would never be routed over the internet. The only reason to deviate from 255.255.255.0 would be if you subneted it to less than /24. The illustration shows a full /24 subnet.
