Implementing and Operating Cisco Data Center Core Technologies (DCCOR) — Question 105

An engineer must configure OSPF in the data center. The external routes have already been redistributed into OSPF. The network must meet these criteria:
* The data center servers must reach services in the cloud and the services behind the redistributed routes.
* The exit point toward the Internet should be propagated only when there is a dynamically learned default route from the upstream router.
Which feature is required?

Answer options

Correct answer: C

Explanation

The correct answer is C, as 'default-information originate' allows the router to advertise a default route into OSPF if it is learned dynamically, meeting the requirement for propagating the exit point to the Internet. Options A and B do not fulfill the requirement for default route propagation, and option D would propagate the default route unconditionally, which is not desired in this scenario.
