Answer: B, D

Explanation:

In the given network topology, when an engineer issues a ping from S1 to S2, the packet will pass through R1 to reach R2 where the TTL value will expire. This is because each hop in the network (each router it passes through) decreases the TTL value by one until it reaches zero. When this happens at R2, it will reply with a TTL exceeded message.
