109Which statement is correct about network protocols?

111The global configuration command ip default-gateway 172.16.100.1 is applied to a switch. What is the effect of this command?
- AThe switch will have a management interface with the address 172.16.100.1.
- BThe switch can be remotely managed from a host on another network.
- CThe switch can communicate with other hosts on the 172.16.100.0 network.
- DThe switch is limited to sending and receiving frames to and from the gateway 172.16.100.1.
112What are two potential network problems that can result from ARP operation? (Choose two.)
- AManually configuring static ARP associations could facilitate ARP poisoning or MAC address spoofing.
- BOn large networks with low bandwidth, multiple ARP broadcasts could cause data communication delays.
- CNetwork attackers could manipulate MAC address and IP address mappings in ARP messages with the intent of intercepting network traffic.
- DLarge numbers of ARP request broadcasts could cause the host MAC address table to overflow and prevent the host from communicating on the network.
- EMultiple 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.
