I think it is A and D. IP packets with the IP options field are handled by the RE and not PFE. Routing protocol updates are handled by the RE. ICMP and TTL traffic is processed by the PFE

correct answer: A, D since, in junOS genius course it says: "examples include, protocol updates for routing protocols, IP packets with the IP options field set" TTL expired? PFE'll drop 'em ICMP destination unreachable? PFE will deal with it

It is A and D for sure, TTL traffic and ICMP messages are handled by the PFE while IP packet option fields and OSPF protocol updates are handled by the RE

It should be A and D. Both TTL expired and ICMP unreachable is handled by PFE.
