A group of Windows PCs in a new subnet has been added to an Ethernet network. When testing the connectivity, a technician finds that these PCs can access local network resources but not the Internet resources.

What are two potential network problems that can result from ARP operation? (Choose two.) A. Large numbers of ARP request broadcasts could cause the host MAC address table to overflow and prevent the host from communicating on the network. B. Multiple ARP replies result in the switch MAC address table containing entries that match the MAC addresses of hosts that are connected to the relevant switch port. C. Manually configuring static ARP associations could facilitate ARP poisoning or MAC address spoofing. D. Network attackers could manipulate MAC address and IP address mappings in ARP messages with the intent of intercepting network traffic. done E.
