Question: 1
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.
Answer: A
Question: 2
Which two statements describe a routed switch port on a multilayer switch? (Choose two.)
A. Layer 2 switching and Layer 3 routing are mutually supported.
B. The port is not associated with any VLAN.
C. The routed switch port supports VLAN subinte***ces.
D. The routed switch port is used when a switch has only one port per VLAN or subnet.
E. The routed switch port ensures that STP remains in the forwarding state.
Answer: BD
Question: 3
Which protocol will enable a group of routers to form a single virtual router and will use the real IP address of a router as the gateway address?
A. Proxy ARP
B. HSRP
C. IRDP
D. VRRP
E. GLBP
Answer: D
Question: 4
Given the configurations on SwitchA and SwitchB, which two statements are true? (Choose two.)
A. The trunk is currently using the ISL trunking protocol.
B. The trunk is currently using the 802.1q trunking protocol.
C. By default, the trunk can only support one VLAN, and only that single VLAN is transmitted across the trunk.
D. By default, all VLANs will be transmitted across this trunk.
E. By default, SwitchA and SwitchB's Fast Ethernet 0/1 port will not generate DTP messages.
Answer: BD
Question: 5
Which trunking protocol inserts a four byte tag into the Ethernet frame and recalculates the CRC value?
A. VTP
B. 802.1Q
C. DTP
D. ISL
Answer: B
Question: 6
By default, which statement is correct when an IEEE 802.1Q trunk port receives an untagged frame?
A. The frame is considered in the native VLAN and forwarded to the ports associated with that VLAN.
B. The frame is encapsulated and tagged as in the native VLAN.
C. The frame is broadcast on all ports regardless of VLAN association.
D. The frame is dropped.
