Which OSPF LSA types were introduced for IPv6 (OSPFv3) and do not apply to IPv4 OSPF? (Choose two.)

OSPFv3 (for IPv6) introduced Link LSAs (Type 8) and Intra-Area Prefix LSAs (Type 9). The Link LSA (Type 8) is a new LSA type that describes the link-local address of the transmitting router, a list of prefixes associated with the link, and options for the network link. The Intra-Area Prefix LSA (Type 9) is used to advertise IPv6 prefixes within an area, replacing the function of Type 1 and Type 2 LSAs for prefix advertisement in OSPFv2. Summary LSA (Type 3) and Router LSA (Type 2) are OSPFv2 LSA types that have different functionalities in OSPFv3. Opaque LSA (Type 9) is an OSPFv2 LSA type, but the Type 9 LSA in OSPFv3 is the Intra-Area Prefix LSA.
