What are two problems that can be caused by a large number of ARP request and reply messages?
(Choose two.)
- 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.
- 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.
- Switches become overloaded because they concentrate all the traffic from the attached subnets.
- All ARP request messages must be processed by all nodes on the local network.
- The ARP request is sent as a broadcast, and will flood the entire subnet.
| Explanation:
ARP requests are sent as broadcasts: A switch does not change its MAC table based on ARP request or reply messages. The switch populates the MAC table using the source MAC address of all frames. The ARP payload is very small and does not overload the switch. |
