Wait, why are we denying ICMP too? Seems excessive.

OSPF is protocol 89, so we need to deny that.

I think option A is the one that denies both OSPF and ICMP correctly, but I’m not completely confident about the command structure.

I’m a bit confused about the ACL numbers. I thought they had to be in a certain range, but I can't recall the specifics right now.

I remember practicing a similar question where we had to filter specific protocols. I feel like option C might be close, but the syntax looks off.

I think the command needs to specifically deny OSPF and ICMP, but I'm not sure which ACL number to use.

Hmm, I'm a bit unsure about this one. I know Ethernet is a LAN technology, but I'm not sure if it's considered a WAN connectivity option. I'll have to think this through carefully.
