How doTCP SYN attacks take advantage ofTCPto prevent new connections from being established to a host under attack？（）

A . All traffic is tagged with a specific VLAN ID from the VLAN of the attacker and is now viewable B . Clients will forward packets to the attacking device， which will in turn send them to the desireddestination but not before recording the traffic patterns C . All traffic is redirected to the VLAN that the attacker used to flood the CAM table D . All traffic is flooded out all ports and an attacker is able to capture all data E . None of the other alternatives apply

A . By perfornubg a show ip interface to see the type and source of the attack based upon the access-listmatches B . By performing a show interface to see the transmitted load "txload" and receive load "rxload" ；if the interface utilization is not maxed out ，there is no attack underway C . By setting up an access-list to permit all ICMP，TCP，and UDP traffic with the log or log-input commands，then use the show access-list and show log commands to determine the type and sourceof attack D . By applying an access-list to all incoming and outgoing interfaces，turning off route-cache on all interfaces，then，when telnetting into the router perform a debug IP packet detail

A . I'm not sure. It depends on the mode your partner chose B . I'm not sure about that. It is a big city C . I don't know for sure. It is quite busy now in our bank

A .  It reverse engineers and documents the attack B .  It looks subjectively at network traffic for abnormal flows of behavior C .  It creates a signature and updates the network security policies D .  It actively monitors all vulnerable areas of the network

A . ...uses VTP to collect VLAN information that is sent out and then tags itself with the domain  information in order to capture the data. B . ...will generate frames with two 802.1Q headers to cause the switch to forward the frames to a  VLAN that would be inaccessible to the attacker through legitimate means. C . ...uses DTP to negotiate trunking with a switch port and captures all traffic that is allowed on the  trunk. D . ...tags itself with all usable VLANs to capture data that is passed through the switch， regardless  of the VLAN to which the data belongs. E . None of the other alternatives apply
