A 24 port layer 2 switch can perform all of the following functions EXCEPT:

Layer 2 switches are fundamentally multi-port bridges that forward frames based on MAC address tables, so bridging is a native and core function.

Routing requires examining and forwarding packets based on IP addresses using a routing table, which is a layer 3 function not present in a layer 2 switch. A layer 2 switch only forwards Ethernet frames based on MAC address tables within the same broadcast domain and has no IP forwarding capability.

Link aggregation (IEEE 802.3ad/LACP) is a layer 2 feature supported by managed switches to bundle multiple physical ports into a single logical higher-bandwidth link.

Full duplex operation is supported by layer 2 switches because each port gets dedicated bandwidth, eliminating collisions and enabling simultaneous bidirectional transmission.
