Which statement about native VLAN traffic is true?
A.
Cisco Discovery Protocol traffic travels on the native VLAN by default.
B.
Traffic on the native VLAN is tagged with 1 by default.
C.
Control plane traffic is blocked on the native VLAN.
D.
The native VLAN is typically disabled for security reasons.
r u sure “A”?
how about “D”
i think “D”
Native VLAN is never disabled by default. By default Vlan1 is the native VLAN (not shown in the running-configuration)
Seems (B) is the correct answer
Per default the native VLAN is VLAN 1 but you can change that:
#show interface Fa0/8 trunk
Port Mode Encapsulation Status Native vlan
Fa0/8 on 802.1q other 1
https://supportforums.cisco.com/discussion/11700441/what-difference-between-default-vlan-and-native-vlan
A is correct
ANS: B is correct
On the switch, the CDP traffic is always preferred on the lowest VLAN configured. That is, VLAN 1 always, which cannot be deleted from the VLAN database.
The CDP protocol behaves differently when the switch sends CDP as a tagged packet or untagged packet dependent upon the native VLAN configured on the trunk link.

New 100-105 Exam Questions (17/Mar/2017 Updated):
NEW QUESTION 297
Which two VLANs are reserved for system use only? (Choose two.)
A. 1
B. 4095
C. 4096
D. 0
E. 1001
Answer: BD
Explanation:
The VLANs 0 and 4095 are reserved by the IEEE 802.1Q standard and you cannot create, delete, or modify them so they are the correct answers.
Note:
– VLAN 0 and 4095 are reserved for system use only. You cannot see or use these VLANs.
– VLAN 1 and VLANs 1002-1005 are default VLANs. Default VLANs are created automatically and cannot be configured or deleted by users.
– VLAN 2 to 1001 are normal VLANs. You can create, use and delete them.
– VLAN 1002 to 1005 are normal VLANs too but Cisco reserved for FDDI an Token Ring.

This question is about Native VLAN. The native VLAN is the VLAN that is configured for packets that don’t have a tag. The default native VLAN on all Cisco Switches is VLAN 1. It is always enabled by default. These settings can all be changed: That is: you can designate a different VLAN as the native VLAN, disable VLAN 1, etc. Knowing that, we can eliminate D) as the correct answer because it is enabled by default. We can also eliminate B) because Native VLAN packets don’t get tags by default (you can change this). Finally, Control Plane traffic is never blocked on Native VLAN 1, and even if you change the Native VLAN, the control plane traffic still comes across VLAN 1. That eliminated answer C) – leaving A) as the only answer.

Typical Cisco trick question.
A is correct. CDP only travels in the “Native Vlan” by default. Yes out of the box it is VLAN 1. However the Native Vlan can be changed.
B is incorrect because traffic (on any vlan) is NOT tagged until the switch is configured to tag the vlan. The question didn’t say that tagging was enable.
I personally think D. is also correct. I am sure that is stated in one of the Cisco Press books.
NEW QUESTION 300
Which sequence begins a unique local IPv6 address in binary notation?
A. 00000000
B. 1111110
C. 1111100
D. 1111111
Answer: B
Looks like it’s C not B ; Unique Local addresses start with fc00::/7 which translate to 11111100
https://www.ripe.net/participate/member-support/lir-basics/ipv6_reference_card.pdf
fc translates to 11111101 idiot. unique local is fc00 through fd00. fd is 11111110 answer = B. even though the answers are all missing a bit. also you cant assume its D (as in they purposefully missed a 0 on the end and meant 11111110) because the leading 0 is necessary to define the binary number. its B.
other way around i mean w/e youre wrong
I just noticed. Do they really give you 7 bits? If it is true that’s a low blow…
