13. 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.
NetworkAddressesIPv4 Address10.128.64.113Subnet mask255.255.252.0Default Gateway10.128.64.1The routers are configured as shown in the following table.

131.107.108.37R2 C interface 1
R2 C interface 210.128.64.10
10.128.4.1WKS1 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 Cp 10.128.4.0/26 10.128.64.10
C. Route add Cp 10.128.4.0 mask 255.255.255.192 10.128.64.1
