Two end stations in a point-to-point network perform address resolution. Which of the following statements is correct?
The destination address of an ARP request from each station will be a unicast MAC address.
The destination address of an ARP request from each station will be a broadcast IP address,
The destination address of an ARP reply from each station will be a unicast MAC address
A. The destination address of an ARP reply from each station will be a broadcast MAC address,
The administrator has configured an IP address for Host A and Host B, but had forgotten to configure a default gateway.
What effect will this have on the hosts?
Neither host will be affected, and therefore will be able to communicate with the peer
Host A will be unable to connect to the router's G0/0/0 interface
Hosts will be unable to communicate unless arp-proxy is enabled on the router
A. The host will be unable to reach neither the local nor remote network destinations.

The administrator uses the ping command on the host to test connectivity to the website www.huawei.com The command line shows a request time out. The administrator displays the ARP entries for the host. Which entry will be found in the ARP cache table of the host?
The MAC address of the destination www.huawei.com will exist in the ARP cache
The MAC address of the switch will exist in the ARP cache.
The IP address of the destination WWW huawei.com will exist in the ARP cache
The MAC address of router interface G0/0/0, will exist in the ARP cache

A server is linked to port interface G0/0/1 of a switch. The administrator wishes to allow only this server to be linked to this interface on the switch.
Which method can be used to achieve this?
Configure a static ARP entry using the server's IP address and MAC address in the switch
Configure a static MAC address binding entry of the server's MAC address and the interface in the switch
