Which type of interface is created on the Cisco Nexus 5548 Switch to represent ports connected to a FEX?

According to my revision notes it’s the LIF on the parent switch, and the VIF is a logical interface on the fex?

Lets take a deep look at the backend operations. There are various interfaces involved:
• HIF (Host Interface): Are the physical user/host interfaces on the FEX. These interfaces receive normal Ethernet traffic before it is encapsulated with the VN-Tag header. Each HIF interface is assigned a unique VN-Tag ID that is used with the encapsulation.
• NIF (Network Interface): Physical uplink interfaces on the FEX. These interfaces can only connect back to the parent switch and carries only VN-Tagged traffic.
• LIF (Logical Interface): Is the logical interface representation of the HIF and its configuration on the parent switch. Forwarding decisions are based on the LIF.
• VIF (Virtual Interface): Is a logical interface on the FEX. The parent switch assigns/pushes the config of a LIF to the VIF of an associated FEX which is mapped to a physical HIF. This is why replacing a FEX becomes trivial in that the broken FEX is unplugged and the replacement is plugged in.
The diagram below should make this a bit more clear:
