Exam H13-511_V5.5 Topic 5 Question 32 Discussion

In the shown topology, RTA and RTB are directly connected on10.0.0.0/24(RTA: 10.0.0.1/24, RTB: 10.0.0.2
/24). RTB and RTC are directly connected on20.1.1.0/24(RTB: 20.1.1.2/24, RTC: 20.1.1.3/24). In HCIA networking fundamentals, a router forwards packets based on its routing table, and thenext hop must be reachable on a directly connected network(or resolved via recursion), meaning it is typically theneighbor router interface on the local link.
* A is false: For traffic fromRTA to RTC (20.1.1.3), RTA's next hop should beRTB's interface 10.0.0.2 (its directly connected neighbor). The address20.1.1.2is not on RTA's directly connected subnet, so it cannot be used as the immediate next hop in this basic routing scenario.
* B is true: RTC must have a route back to10.0.0.0/24(for return traffic to RTA). Since RTC only knows its directly connected network20.1.1.0/24, a static/default route is required pointing to20.1.1.2.
* C is true: RTB has two directly connected networks (10.0.0.0/24 and 20.1.1.0/24), so it can reach both RTA and RTC withno additional routes.
* D is false: RTB does not need extra routing configuration for RTA#RTC communication because both networks are alreadydirectly connectedon RTB.
