Cisco Implementing Cisco IP Switched Networks 認定 642-813 試験問題:

1. Refer to the exhibit.

An attacker is connected to interface Fa0/11 on switch A-SW2 and attempts to establish a DHCP server for a man-in-middle attack. Which recommendation, if followed, would mitigate this type of attack?

A) All switch ports connecting to servers in the Server Farm block should be configured as DHCP untrusted ports.
B) All switch ports in the Building Access block should be configured as DHCP untrusted ports.
C) All switch ports connecting to hosts in the Building Access block should be configured as DHCP trusted ports.
D) All switch ports in the Building Access block should be configured as DHCP trusted ports.
E) All switch ports connecting to hosts in the Building Access block should be configured as DHCP untrusted ports.
F) All switch ports in the Server Farm block should be configured as DHCP untrusted ports.

2. The DAI feature has been implemented in the ACME switched LAN. Which three statements are true about the dynamic ARP inspection (DAI) feature? (Select three)

A) DAI is supported on access ports, trunk ports, EtherChannel ports, and private VLAN ports.
B) DAI can be performed on both ingress and egress ports.
C) DAI should be configured on all access switch ports as untrusted and on all switch ports connected to other switches as trusted.
D) DAI is supported on access and trunk ports only.
E) DAI should be enabled on the root switch for particular VLANs only in order to secure the ARP caches of hosts in the domain.
F) DAI can be performed on ingress ports only.

3. 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 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.
C) 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.
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.

4. A network administrator enters the following switch commands:
Switch(config)#interface range fa0/0-5
Switch(config-if-range)#switchport access vlan 2
What is the result of these commands?

A) Six new vlans are created on six switch ports
B) One new vlan is created on five switch ports
C) One new vlan is created with the vlan number 2
D) Two new vlans are created on six switch ports
