This is on Page 209 of BCMSN 4th Edition Self-Study Guide CCNP Learning by Froom, Sivasubramanian, Erum. The following is the configuration given in the review questions of Chapter 4 (Ex 4-31, Pg 209):
no ip address
switchport access vlan 5
switchport trunk encapsulation dot1q
And the following questions multiple choices are given:
Question: Which statement is true regarding the interface?
a) The interface is a member of VLAN 5 and may negotiate to trunk port.
b) The interface may negotiate to an ISL trunk with a Native VLAN of 5.
c) The interface may negotiate to an 802.1Q trunk and operate with a Native VLAN of 1
d) The interface will not neotiate to a trunk port because it is configured in access VLAN-5
Isn't the answer "d", but the book says its "a". Could anyone clarify why?
Also, looking at the configuration why would there be encapsulation on an access port. Isnt access port part of only one VLAN?
And DTP messages are sent on trunk ports only when the mode is set to NEGOTIATE, coorect?
