300-115 874惊险通过，LACP,170选择题和实际考试有出入！！！！！

artdao1987

先说选择题170，有一个选项变成了The native vlan must be the same and allowed on the trunk,这个选项貌似比正确答案D还要准确点，最后我选择了相信题库。
/ Q6 ~3 _9 C. X- ARefer to the exhibit.
A network engineer changes the default native VLAN to VLAN 999. After applying the settings on the
uplinks to the core switches, the switch control traffic, such as CDP and VTP, is no longer working. The
standard configuration is used for each uplink. What is wrong with the configuration?
A. The interface is administratively down.
B. The encapsulation type is incorrect.
; T4 o' u0 z+ E" A# UC. The switchport mode trunk command should be first in the output.
D. The native VLAN is not present on the trunk.
E. The control traffic must be manually enabled on the new native VLAN.

再说LACP SWB的F0/3,端口封装模式始终是Undefined,怎么shut，no shut，单独，rang配置都不行，导致channel状态是down的，这个问题从3月6号的战报里就能看出来了，大家都有碰到，其他我敢保证没有错，最后874感觉这两题都错了，望大神解惑！！！

题库还稳定？

我反正没听懂你说的关于实验的话，语无伦次

我想问的是，你在inter port-channel 1 下有没有对trunk进行封装dot1q

月缺思盈

还有你的port-channel下有没有敲no shut

. b/ Y# X  m! F7 H我既然概括说了，就说明我都尝试过了，你可以去看看3月6号以后的战报，有些人说的很详细了，没必要再说一遍。

已经预约下周一考试了。请解答下LACP的试验配置问题吧！！！

楼主 题库是稳定的 今天刚刚考过 LACP题目也很正常

解答一 interface port-channel 1 下可以不需要配置Dot1Q封装 因为在物理接口Fa0/3 - 4 你已经配置了。只需做Trunk Mode; Trunk native vlan & Trunk allowed vlan就可以了 还有记得no shutdown

选择题170，答案为D没有错,

- ~# r+ B0 B- P# ]. z  l9 ~5 m: o  B$ S前Native vlan must be the same <==正确
后 and allowed on the trunk<==有误
Native本就不带Tag,不需要allow trunk

恭喜，恭喜

题目要求:What is wrong with the configuration?   是要找出"错误"的配置,那选新的选项就OK了吧?
