What are two problems that can be caused by a large number of ARP request and reply messages? (Choose two.)

Switches become overloaded because they concentrate all the traffic from the attached subnets.

The ARP request is sent as a broadcast, and will flood the entire subnet.

The network may become overloaded because ARP reply messages have a very large payload due to the 48-bit MAC address and 32-bit IP address that they contain.

A large number of ARP request and reply messages may slow down the switching process, leading the switch to make many changes in its MAC table.

All ARP request messages must be processed by all nodes on the local network.
