QID:BCM420 ADMIN: please give a source of the answer - uno4 - 04-25-2009

refer to question QID:BCM420: Which two statements are true about the required switch configurations to support a voice VLAN?

1) Static secure MAC addresses should be configured on voice vlan ports to
    prevent access by devices other than IP phones.

2) CDP must be disabled on the switch port to prevent interference between
      CDP messages and voice traffic.

3) 802.1x authentication cannot be configured on a port configured for a voice vlan.

4) CDP must be enabled on the switch port to allow configuration information to be passed to the IP phone.

5) Portfast must be enabled on the switch port.

6) Port security cannot be configured on a port that is configured for a voice vlan.


Correct Answer: 4) CDP must be enabled on the switch port to allow configuration information to be passed to
                                the IP phone.
                            5) Portfast must be enabled on the switch port.


ADMIN: Can you give a source for the 2nd answer 5) please? I couldn't find any hint of that. Neither in CCNP BCMSN Official Exam Certification Guide (Fourth Edition), David Hucaby
nor in the curriculum Network Academy Program "BCMSN".


Thanks

I believe the answer should be 4 and 6.

Can anyone verify what the answers should be, with reference cited.

Thanks
