Answer: B

Explanation:

When all the users cannot reach internet sites we should check on the router connecting to the ISP to see if it has a default route pointing to the ISP or not.

Use the “show ip route” command on R1:

We cannot find a default route on R1 (something like this: S* 0.0.0.0/0 [1/0] via 209.165.201.2) so maybe R1 was not configured with a default route.

We can check with the “show running-config” on R1:

We need a default route (like “ip route 0.0.0.0 0.0.0.0 209.165.201.2”) but we cannot find here so we can conclude R1 was not be configured with a default route pointing to the ISP router.
