B. The switch ports 3/1 and 3/2 and the ports connecting to the two firewalls will be defined as primary VLAN promiscuous ports.
C. The switch ports 3/1 and 3/2 and the ports connecting to the two firewalls will be defined as primary VLAN community ports.
D. The switch ports 3/1 and 3/2 will be defined as secondary VLAN isolated ports. The ports connecting to the two firewalls will be defined as primary VLAN promiscuous ports.

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.
You work as a network technician at Company. Your boss, Mrs. , is interested in
switch spoofing.
She asks you how an attacker would collect information with VLAN hoping through switch spoofing. You should tell her that the attacking station... （）
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
