NO.1 Which three statements are correct regarding Layer 2 overlay VPNs and peer-to-peer VPNs?
(Choose three.)
A.Peer-to-peer VPNs require the establishment of virtual circuits to connect the different customer sites
together.
B.Peer-to-peer VPNs require the service provider to participate in the customer routing, accepting
customer routes, transporting them across the service provider backbone, and finally propagating them to
other customer sites.
C.With peer-to-peer VPNs, the service provider is responsible for transport of Layer 2 frames between
customer sites, and the customer takes responsibility for all higher layers.
D.The implementation of Layer 2 overlay VPNs is the traditional switched-WAN model, implemented with
technologies like X.25, Frame Relay or ATM.
E.With Layer 2 overlay VPNs, the service provider is not aware of customer routing and has no
information about customer routes.
F.It is simple to implement Layer 2 overlay VPNs because the Customer Edge (CE) router just needs a
connection to the Service Provider's Provider Edge (PE) router.

NO.1 Which three statements are true about multicast IGMP snooping? (Choose three.)
A.When a host in a multicast group sends an IGMP leave message, only that port is deleted from the
multicast group.
B.An IP multicast stream to the IP host can be stopped only by an IGMP leave message.
C.IGMP snooping does not examine or snoop Layer 3 information in packets that are sent between the
hosts and the router.
D.When the switch hears the IGMP host report from a host for a particular multicast group, the switch
adds the host's port number to the associated multicast table entry.
E.IGMP control messages are transmitted as IGMP multicast packets so that they can be distinguished
from normal multicast data at Layer 2.
F.A switch that is running IGMP snooping examines every multicast data packet to verify whether it
contains any pertinent IGMP "must control" information.

NO.12 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.

C. ARP spoofing can be used to redirect traffic to counter Dynamic ARP Inspection.
D. Dynamic ARP Inspection in conjunction with ARP spoofing can be used to counter DHCP snooping

NO.17 Refer to the exhibit.
DHCP snooping is enabled for selected VLANs to provide security on the network. How do the switch
ports handle the DHCP messages?
A. A DHCPOFFER packet from a DHCP server received on Ports Fa2/1 and Fa2/2 is dropped.
B. A DHCP packet received on ports Fa2/1 and Fa2/2 is dropped if the source MAC address and the
DHCP client hardware address does not match Snooping database.
C. A DHCP packet received on ports Fa2/1 and Fa2/2 is forwarded without being tested.
D. A DHCPRELEASE message received on ports Fa2/1 and Fa2/2 has a MAC address in the DHCP
snooping binding database, but the interface information in the binding database does not match the
interface on which the message was received and is dropped.

NO.20 Refer to the exhibit.
The web servers WS_1 and WS_2 need to be accessed by external and internal users. For security
reasons, the servers should not communicate with each other, although they are located on the same
subnet. However, the servers do need to communicate with a database server located in the inside
network. Which configuration isolates the servers from each other?
A. The switch ports 3/1 and 3/2 are defined as secondary VLAN isolated ports. The ports connecting to
the two firewalls are defined as primary VLAN promiscuous ports.
B. The switch ports 3/1 and 3/2 are defined as secondary VLAN community ports. The ports connecting to
the two firewalls are defined as primary VLAN promiscuous ports.
C. The switch ports 3/1 and 3/2 and the ports connecting to the two firewalls are defined as primary VLAN
promiscuous ports.
D. The switch ports 3/1 and 3/2 and the ports connecting to the two firewalls are defined as primary VLAN
community ports.
