NO.7 Refer to the exhibit.
What information can be derived from the output?
A. Interfaces FastEthernet3/1 and FastEthernet3/2 are connected to devices that are sending BPDUs
with a superior root bridge parameter and no traffic is forwarded across the ports. After the sending of
BPDUs has stopped, the interfaces must be shut down administratively, and brought back up, to resume
normal operation.
B. Devices connected to interfaces FastEthernet3/1 and FastEthernet3/2 are sending BPDUs with a
superior root bridge parameter, but traffic is still forwarded across the ports.
C. Devices connected to interfaces FastEthernet3/1 and FastEthernet3/2 are sending BPDUs with a
superior root bridge parameter and no traffic is forwarded across the ports. After the inaccurate BPDUs
have been stopped, the interfaces automatically recover and resume normal operation.
D. Interfaces FastEthernet3/1 and FastEthernet3/2 are candidates for becoming the STP root port, but
neither can realize that role until BPDUs with a superior root bridge parameter are no longer received on
at least one of the interfaces.

NO.8 When an attacker is using switch spoofing to perform VLAN hopping, how is the attacker able to gather
information?
A. The attacking station uses DTP to negotiate trunking with a switch port and captures all traffic that is
allowed on the trunk.
B. The attacking station tags itself with all usable VLANs to capture data that is passed through the switch,
regardless of the VLAN to which the data belongs.
C. The attacking station generates 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.
D. The attacking station uses VTP to collect VLAN information that is sent out and then tags itself with the
domain information to capture the data.

NO.17 Which description correctly describes a MAC address flooding attack?
A. The attacking device crafts ARP replies intended for valid hosts. The MAC address of the attacking
device then becomes the destination address found in the Layer 2 frames sent by the valid network
device.
B. The attacking device crafts ARP replies intended for valid hosts. The MAC address of the attacking
device then becomes the source address found in the Layer 2 frames sent by the valid network device.
C. The attacking device spoofs a destination MAC address of a valid host currently in the CAM table. The
switch then forwards frames destined for the valid host to the attacking device.
D. The attacking device spoofs a source MAC address of a valid host currently in the CAM table.
The switch then forwards frames destined for the valid host to the attacking device.
E. Frames with unique, invalid destination MAC addresses flood the switch and exhaust CAM table space.
The result is that new entries cannot be inserted because of the exhausted CAM table space, and traffic is
subsequently flooded out all ports.
F. Frames with unique, invalid source MAC addresses flood the switch and exhaust CAM table space.
The result is that new entries cannot be inserted because of the exhausted CAM table space, and traffic is
subsequently flooded out all ports.
