How to analyze network traffic passing through a switch?
To analyze network traffic passing through a switch, switched port analyzer (SPAN) can be used. SPAN can send a copy of traffic from one port to another port on the same switch where a network analyzer or monitoring device is connected.
Which switch should be able to obtain IP address assignments from DHCP?
PC1 and PC2 should be able to obtain IP address assignments from the DHCP server. How many ports among switches should be assigned as trusted ports as part of the DHCP snooping configuration?
How many times can the destination IP address change in a frame?
(Choose two.) A packet that has crossed four routers has changed the destination IP address four times. Destination MAC addresses will never change in a frame that goes across seven routers. Destination and source MAC addresses have local significance and change every time a frame goes from one LAN to another. *
How many switch ports should be assigned to a DHCP server?
In this network design, because the DHCP server is attached to AS3, seven switch ports should be assigned as trusted ports, one on AS3 toward the DHCP server, one on DS1 toward AS3, one on DS2 toward AS3, and two connections on both AS1 and AS2 (toward DS1 and DS2), for a total of seven. 8.
How does a DHCPDISCOVER attack work?
To accomplish this goal, the attacker uses a tool that sends many DHCPDISCOVER messages in order to lease the entire pool of available IP addresses, thus denying them to legitimate hosts. 3. The exhibit shows a network consisting of a router, two switches, a DHCP client host, an attacker host, and a DHCP server.
Which interface on switch S1 should be configured as a DHCP snooping trusted?
Which interface on switch S1 should be configured as a DHCP snooping trusted port to help mitigate DHCP spoofing attacks? When DHCP snooping is configured, the interface that connects to the DHCP server is configured as a trusted port.
