It’s B because ND inspection matches IPv6 addresses to MACs, which are Layer 2 identifiers, and it mainly deals with stateless autoconfig addresses. So securing those bindings fits Layer 2 neighbor tables better than Layer 3.
It’s A because ND inspection mainly focuses on stateless addresses from SLAAC and secures their Layer 3 bindings, not stateful or Layer 2 ones. That fits the function better than the others.
D imo, stateful autoconfig means DHCPv6, which handles IP assignments tied to Layer 3 info. ND inspection should secure those bindings at Layer 3, not Layer 2 like B suggests.
Maybe B, since ND inspection ties IPv6 addresses to MACs, which suggests Layer 2 neighbor tables, not Layer 3. It’s about securing address-MAC bindings for stateless addresses, so B fits better than A.
Option A makes sense since ND inspection is about Layer 3 IP bindings with stateless addresses.
Maybe A. From what I remember, IPv6 ND inspection mainly deals with securing the mappings for stateless autoconfig addresses, which are part of SLAAC. Since those addresses need to be matched to IPs in Layer 3 neighbor tables, it makes sense that the inspection works there. Layer 2 neighbor tables usually handle MAC addresses, but ND inspection is more about IP-to-MAC bindings at the network layer. So I’d say it’s about learning and securing stateless autoconfig in Layer 3 neighbor tables rather than stateful or Layer 2-specific stuff.
B/D? I think it’s about securing Layer 2 since ND deals with MAC addresses, but I’m not sure if it’s stateless or stateful autoconfig. The “stateful” part usually involves DHCPv6, so maybe D fits better?
B tbh, it’s gotta be about Layer 2 neighbor tables since ND inspection deals with link-layer info, not just IP addresses. Plus, stateless autoconfig fits better here because IPv6 ND helps devices get addresses without a server, so option B makes more sense than anything talking about stateful or Layer 3.
Option A, it’s about Layer 3 and stateless addresses.
