QUESTION 229
What is the process to configure EtherChannel?
A. shutdown both interface ports
B. shutdown the interface on one side only
C. Shutdown is necessary if the ports are in err-disable
D. Don't need to shutdown the ports
在配置EtherChannel時，為了避免STP在協定時不一致，所以建議的做法是要shutdown兩邊的介面，在設定完後再啟用。當然不這樣做也沒差，也可以設定。但答案A是正確的沒錯。

QUESTION 591
What is the command to enable BPDU filter on an access port?
A. spanning-tree portfast bpdufilter default
B. spanning-tree portfast bpduguard default
C. spanning-tree bpdufilter enable
D. spanning-tree bpdufilter default
這題要再access port設置BPDU filter，答案是C。但我不知道為啥網友會說是其他選項.....

QUESTION 603
A question about message TACACS+ server with two choices. (Choose two.)
A. error
B. hello
C. continue
D. transmit
E. request
這題完整題目不完整，不知道問啥。但我看選像他應該是在問TACACS+ server 的回應程序有哪些。
ACCEPT--The user is authenticated and service may begin. If the network access server is configured to requite authorization, authorization will begin at this time.
REJECT--The user has failed to authenticate. The user may be denied further access, or will be prompted to retry the login sequence depending on the TACACS+ daemon.
ERROR--An error occurred at some time during authentication. This can be either at the daemon or in the network connection between the daemon and the network access server. If an ERROR response is received, the network access server will typically try to use an alternative method for authenticating the user.
CONTINUE--The user is prompted for additional authentication information.
所以選擇AC

QUESTION 608
What is the default VTP operating mode for the MST feature?
A. server
B. client
C. transparent
D. off
這題C，沒東西可以討論@@"

QUESTION 610
Which two statements about source port monitoring in a SPAN are true? (Choose two.)
A. Traffic through a destination port can be copied and included in the SPAN session.
B. The entire EtherChannel must be monitored.
C. It can monitor only FastEthernet and GigabitEthernet port types.
D. It can monitor individual interfaces within a port channel.
E. It can monitor ingress and egress traffic.
這題我選DE，A選項感覺講反了，但這題我不確定。

QUESTION 611
Which two commands display the VLANs that are present in the VLAN database? (Choose two.)
A. show running-config
B. show vlan database
C. show vlan brief
D. show vlan
E. show vlan id
這題我會選DE，A是一定錯的，show run看到的資料不是存在vlan.dat裡面，跟題目要的VLAN database不同。

QUESTION 625
Which two statements about the LACP port priority of a device are true? (Choose two.)
A. To manually configure a link within an EtherChannel to come up first, set its LACP port-priority value lower than the default.
B. LACP port-priority is used in the hashing algorithm to load-balance links within an EtherChannel.
C. The systems uses the port priority of the local and remote devices to determine which links in an EtherChannel group are active.
D. It determines which links in an EtherChannel group are active.
E. To manually configure a link within an EtherChannel to come up first, set its LACP port-priority value lower than the default.
F. The system uses the port priority of the local and remote devices to determine which links in an EtherChannel group are host-standby
這題答案A(E)F，E選項我看起來跟A一模一樣@@   這題在考LACP的port priority，這東西的功能是LACP的Hot standby用的，可以讓單個EtherChannel最多可以設定16個port(8個使用中，8個備援)，哪個port使用、備援就是靠port priority來決定。只有AF是跟Hot standby有關，其他選項都來亂的。

591 608 610答案应该是对的，其他就不清楚了

610，A答案说的是将目的端口的流量copy，不应该是复制source吗？
608，我在模拟器上做的实验，无论是vtp v2还是v3，当你配置mst的时候vtp是server也行，transparent也行

591我在模拟器上敲怎么是C

IOS版本不一样，BPDU filter一般指配置在port fast上面 而且在接口的配置和全局的配置也不一样

不好意思 610 看错了 那目的端口看成了源端口

Which type of port can serve as StackWise Virtual link?
A. downlink only
B. uplink only
C. switched port
D. any physical port
如果是考VSL的type種類的話，那答案會是D，只要是任意實體介面，都可以設置成VSL。

QUESTION 668、692
沒玩過IP phone ，看題號也是新題，這題我也不會@@
