Correct Answer: ATo configure R1 so that PC1 can communicate with all PCs in the 10.10.10.0/24 network, two static routes need to be added. Firstly, the command 'ip route 10.10.10.0 255.255.255.0 192.168.2.3' tells R1 to route any traffic destined for the 10.10.10.0/24 network through the next hop at 192.168.2.3 (R2). This covers the communication to the broader network. Secondly, although the line 'ip route 10.10.10.10 255.255.255.255 192.168.2.2' seems redundant at first glance, it specifically points a single host route which ensures that packets can be directed precisely. Therefore, the suggested commands in option A are correct.
