NO.1 Refer to the exhibit.
GLBP has been configured on the network. When the interface serial0/0/1 on router R1 goes down, how
is the traffic coming from Host1 handled?
A. The traffic coming from Host1 and Host2 is forwarded through router R2 with no disruption.
B. The traffic coming from Host2 is forwarded through router R2 with no disruption. Host1 sends an ARP
request to resolve the MAC address for the new virtual gateway.
C. The traffic coming from both hosts is temporarily interrupted while the switchover to make R2 active
occurs.
D. The traffic coming from Host2 is forwarded through router R2 with no disruption. The traffic from Host1
is dropped due to the disruption of the load balancing feature configured for the GLBP group.
Answer: A

NO.4 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.5 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.
