Q1. DHCP snooping and IP Source Guard have been configured on a switch that connects to several client workstations. The IP address of one of the workstations does not match any entries found in the DHCP binding database. Which statement describes the outcome of this scenario?
A. Packets from the workstation will be rate limited according to the default values set on the switch.
B. The interface that is connected to the workstation in question will be put into the errdisabled state.
C. Traffic will pass accordingly after the new IP address is populated into the binding database.
D. The packets originating from the workstation are assumed to be spoofed and will be discarded.
Answer: D

Q4. An administrator recently configured all ports for rapid transition using PortFast. After testing, it has been determined that several ports are not transitioning as they should. What is the reason for this?
A. RSTP has been enabled per interface and not globally.
B. The STP root bridge selection is forcing key ports to remain in non-rapid transitioning mode.
C. STP is unable to achieve rapid transition for trunk links.
D. The switch does not have the processing power to ensure rapid transition for all ports.

Q9. which statement about the use of PAgP link aggregation on a Cisco switch that is running Cisco IOS Software is true?
A. PAgP modes are off, auto, desirable, and on. Only the combinations auto-desirable, desirable-desirable, and on-on allow the formation of a channel.
B. PAgP modes are active, desirable, and on. Only the combinations active-desirable, desirable-desirable, and on-on allow the formation of a channel.
C. PAgP modes are active, desirable, and on. Only the combinations active-active, desirable-desirable, and on-on allow the formation of a channel.
D. PAgP modes are off, active, desirable, and on. Only the combinations auto-auto, desirable-desirable, and on-on allow the formation of a channel.
Answer: A
