Your company has an IPv4 Ethernet network.
A router named R1 connects your segment to the Internet. A router named R2 joins your subnet with a segment named Private1. The Private1 segment has a network address of 10.128.4.0/26. Your computer named WKS1 requires access to servers on the Private1 network. The WKS1 computer configuration is as shown in the following table.
WKS1 is unable to connect to the Private1 network by using the current configuration. You need to add a persistent route for the Private1 network to the routing table on WKS1.
Which command should you run on WKS1?
A.
Route add -p 10.128.4.0/22 10.128.4.1
B.
Route add -p 10.128.4.0/26 10.128.64.10
C.
Route add -p 10.128.4.0 mask 255.255.255.192 10.128.64.1
D.
Route add -p 10.128.64.10 mask 255.255.255.192 10.128.4.0
Why couldn’t the answer be C
Aww. I see why now. Because there isn’t an IP address 10.128..64.1 in the table.
On the r2 interfaces
I still maintain that C is the correct answer here. When adding a route you have to mention the mask part of it.
nope you don’t need a mask if you specify /26 (or whatever the CIDR notation would be) C is wrong because that’s the wrong gateway 64.1 is the route to the local segment not the private one.
