How does a DHCP server dynamically assign IP addresses to hosts?()
A.Addresses are permanently assigned so that the host uses the same address at all times.B.Addresses are assigned for a fixed period of time. At the end of the period, a new request for an address must be made, and another address is then assigned.C.Addresses are leased to hosts. A host will usually keep the same address by periodically contacting the DHCP server to renew the lease.D.Addresses are allocated after a negotiation between the server and the host to determine the length of the agreement.

Anytime a host or a router has an IP datagram to send to another host or router, it has the（ ）address of the receiver. This address is obtained from the DNS if the sender is the host or it is found in a routing table if the sender is a router. But the IP data gram must be（ ） in a frame to be able to pass through the physical network. This means that the sender needs the （ ）address of the receiver. The host or the router sends an ARP query packet. The packet includes the physical and IP addresses of the sender and the IP address of the receiver. Because the sender does not know the physical address of the receiver, the query is（ ） over the network.Every host or router on the network receives and processes the ARP query packet, but only the intended recipient recognizes its IP address and sends back an ARP response packet.The response packet contains the recipient's IP and physical addresses. The packet is（请作答此空） directly to the inquirer by using the physical address received in the query packet.
A. multicast
B. unicast
C. broadcast
D. multiple unicast

The Dynamic Host Configuration Protocol provides configuration parameters to Internet（ ）.DHCP consists of two components:a（ ）for delivering host-specifie configuration parameters from a DHCP server to a host and a mechanism for allocation of network addresses to hosts.DHCP is built on a client-server model,where designated DHCP server hosts allocate network addresses and deliver（ ）parameters to dynamically configured hosts.DHCP supports three mechanisms for IP address allocation.In“automatic allocation”,DHCP assigns a（本题）IP address to client.In“dynamic allocation”,DHCP assigns an IP address to a client for a limited period of time.In“manual allocation”,a client’s IP address is assigned by the network（ ）,and DHCP is used simply to convey the assigned address to the client.A.permanent
B.dynamic
C.connection
D.session

The Company security administrator is concerned with layer 2 network attacks. Which two statements about these attacks are true？ （）A、 ARP spoofing attacks are attempts to redirect traffic to an attacking host by encapsulating a false 802.1Q header on a frame and causing traffic to be delivered to the wrong VLAN.B、 ARP spoofing attacks are attempts to redirect traffic to an attacking host by sending an ARP message with a forged identity to a transmitting host.C、 MAC address flooding is an attempt to force a switch to send all information out every port byoverloading the MAC address table.D、 ARP spoofing attacks are attempts to redirect traffic to an attacking host by sending an ARP packet that contains the forged address of the next hop router.E、 MAC address flooding is an attempt to redirect traffic to a single port by associating that port with all MAC addresses in the VLAN.
