Refer to the exhibit. The default-information originate command is configured under the R1 OSPF configuration. After testing, workstations on VLAN 20 at Site B cannot reach a DNS server on the Interne

R2 is an internal router in the OSPF domain and does not directly connect to the Internet; adding `default-information originate` on R2 would not resolve the issue of R1 not having a default route to redistribute.

Adding the `always` keyword would force R1 to advertise a default route even if it doesn't have one, which would result in blackholing traffic because R1 wouldn't know how to reach the Internet itself.

The `default-information originate` command requires the router (R1) to have a default route in its own routing table to redistribute it into OSPF. Configuring `ip route 0.0.0.0 0.0.0.0 10.10.10.18` on R1 provides this necessary default route, pointing towards the Internet via the next-hop 10.10.10.18.

Configuring a default route on R2 pointing to 10.10.10.2 (R1) is unnecessary for R2 to learn a default route from R1 via OSPF, and it doesn't solve R1's inability to originate the default route.
