Why each option
The `show ip route` output for R7 confirms the presence of a default route, which means R7 has a gateway of last resort available for destinations not explicitly in its routing table.
The output clearly indicates a gateway of last resort, making the statement that R7 is missing one factually incorrect.
While this statement is true, it is identical to option D, which is a common occurrence in certification questions, with both technically correct.
The output clearly indicates a gateway of last resort, making the statement that R7 is missing one factually incorrect.
The `show ip route` output explicitly states 'Gateway of last resort is 10.10.10.1 to network 0.0.0.0'. This entry confirms that R7 has a default route configured, which serves as its gateway of last resort for forwarding packets to unknown destinations.
