Which three statements are true about LACP port priority?
A. Port priority value can be configured between 1 and 65535.
B. A higher port priority value means a higher priority of LACP.
C. Port priority can be configured so that specific links can be chosen as active links rather than the hot standby links within the port channel.
D. LACP uses the port priority with the port number to form the port identifier.
E. LACP Port priority default value should always be changed

@Rakichi
Are you sure B ?
“The values for the priority range from 0 to 65535. The lower the value, the higher the system priority. The switch with the lower system priority value determines the links between the LACP partner switches that are in active and standby states for each LACP port channel”

I agree with Switchy.

I think the two most correct answers are:

A. The system uses the port priority of the local and remote devices to determine which links in an EtherChannel group are hot-standby.
C. The system uses the port priority of the local and remote devices to determine which links in an EtherChannel group are active.

When setting the priority, note that a higher number means a lower priority.

Heres another good one:

Which two operational attributes can be checked for EtherChannel ports that are in err-disabled state? (Choose two.)
A. Port mode
B. Port cost
C. Duplex
D. DTP
E. VLAN

Some say C. Duplex and E. VLAN

but I think “operational attributes” makes reference to the output of ‘show interface switcport’. Here we can only find Port Mode and VLAN. So I think the answer is A and E

Anyone disagree?

Kindly update with new Q & A as this is the last blow for helping us with this existing 300-115. Your help is highly appreciated.

Did any one face this question?

You want to configure port security on an interface, which two tasks must you perform?

Which two operational attributes can be checked for EtherChannel ports that are in err-disabled state? (Choose two.)
A. Port mode
B. Port cost
C. Duplex
D. DTP
E. VLAN

ANS: A & E

@Boxing_Surfer

When i do the lab for STP/LACP and complete. When i do a sh int trunk i get all the vlans in allowed and management . You only had vlans 1,21-23. Am i missing something please?

Sw_B(config-if-range)#do sh int tr
Port Mode Encapsulation Status Native vlan
Po1 on 802.1q trunking 99

Port Vlans allowed on trunk
Po1 1-1005

Port Vlans allowed and active in management domain
Po1 1,11,12,13,21,22,23,99

Port Vlans in spanning tree forwarding state and not pruned
Po1 1,21,22,23

@Boxing_Surfer @Karim
also…. are you going to name the VLANs on switch A ? instructions dont say to but maybe for completeness? Also name the default VLAN on switch B ?

@Switchy

Did you do ‘Manual Trunk Pruning’ on the trunk? The lab instructions say this is a requirement

On interface Po1 on both switches:
switchport trunk allowed vlans *VLAN LIST*

Also I did name the vlans 21,22 and 23 when created, yes

@Switchy

Lab Requirements:

“For operational and security reasons trunking should be unconditional and Vlans 1, 21, 22 and 23 should tagged when traversing the trunk link….”

I interpret this to mean ‘manual trunk pruning’ is required, as none of the other VLAN’s are specified here. If not, then other VLANs will be tagged on the trunk if there are interfaces active on those VLANs

It’s somewhat my interpretation but this is how i do it anyway.

@ Switchy

on switch B vlans must created and with name yes switch already created if not then need to create

@ REPLACE WWW BY . to AND GET DUMPS

GO TO HELL looser still trying to sell dumps ???

why creating spams u worm

I passed today , 8xx. HRSP ,VTP and LACP lab , D&D , Stackwise vs VSS + HRRP vs VRRP. Some new questions, but once you know the concepts, you will be good. Good luck to those doing the exam in the next 5 days . Thanks to Certprep and this forum for the advice

@ REPLACE WWW BY . to AND GET DUMPS

You have been saying you have passed “today” for the last few months.
You’ve got 5 days left, come on put some effort in, change the bullshit story a little bit at least.

You’ve got this! You can sell someone your shitty dumps!! You can do it!

@Boxing_Surfer / Karim

do you add the below to the port-channel on A, B or both please?….its not required in the premium sims.????

interface port-channel 1
switchport mode trunk
switchport trunk vlan native 99
switchport trunk vlan allowed 1,21-23
no shutdown

also @Boxing_Surfer

i noticed on page 81 in your output of “show run | begin spanning-tree” you had….
spanning-tree vlan 1,11-13,21-23 priority 24576 (note vlan 1)

– SwitchA needs to be the root switch for vlans 11, 12, 13, 21, 22 and 23.

Was this an error or intentional please?

@Switchy

the port channel config looks ok to me

when i do my lab (and generally in real life), I shutdown the physical ports on one of the switches before i add them to the channel group. This avoids any operational errors while config is in progress.

Then when the configuration is finished i ‘no shut’ on the same ports to bring up the completed etherchannel

careful also with your commands. should be ‘switchport trunk vlan allowed vlan 1,21-23’. you missed the ‘vlan’ keyword

As for your second comment. I did not notice that I add vlan 1 to the the root priority explicitly. Thats my mistake. Thank you for spotting it :)

When i do these labs I just do like I would do them in real life. I read the instructions and make the config in real time. I probably misread the requirement. I should pay more attention in the exam

@Switchy.

Yeah you are right. i read the requirement again. it is as you said, so that definitely a misake from me.

I was doing the lab at speed yesterday. I really appreciate your keen eye coz I would have failed the exam if i did that. :)

hahaha.

I am digging through old questions and found some really nasty ones. Badly worded and wrong answers. I will post more analysis tomorrow. I would appreciate your input in the corrections

@Boxing_Surfer
Will give my best effort! You do sound like you have this exam nailed though :)

@Switchy

I dont feel that confident. I do this for a living, and some of the questions im reading are really difficult. Im not sure if they will be on the exam in the exact form they appear in the various PDF’s but even if they are similar I am still quite confused about the answers

I took this exam yesterday and failed. I added the commands to the physical as well as logical interfaces. So, I’m not sure what the answer is.
Anyhow good luck to the rest of you.

@Jockson

were you able to remember what are D&D questions and SIMS came out? thank you.

which two packet types are used by the TACACS+ authentication process (choose two)

A – request
B – response
C – reply
D – continue
E – start

This is messed up

accoring to : http://www.ciscopress.com/articles/article.asp?p=25471&seqNum=6

TACACS+ authentication has three packet types: START, CONTINUE, and REPLY.

@BoxingSurfr

A Request
B Response

@Bingo

Not true

A Request
B Response

These are the packet types for TACACS+ Authorisation process. Not Authentication

Another one. I think I got this one sorted….

Which type of packet does DHCP snooping continuously check in a production network?

A. DHCP Snooping
B. DHCP Relay
C. DHCP Request
D. DHCP Acknowledge
E. DHCP Reply
F. DHCP Allow

There are only two valid answers – Request and Acknowledge

I’ve performed a lot of labs on DHCP snooping in this week with debugs, and this is what I know.

DHCP discover wont get forwarded on any untrusted port. But i dont think that qualifies as ‘checking’. The discover contains no IP address for DHCP to use in creating the binding in the database. If we are talking about the packet type that DHCP snooping uses to build the binding entry in the database, the answer would be ACK

So correct answer is D

@Bingo

I made mistake with the typing but you are still not correct I think

A Request
B Response

These are the packet types for TACACS+ *Accounting* process. Not Authentication

Which two statements about source port monitoring in SPAN are true? (Choose two.)

A. It can monitor individual interfaces within a port channel.
B. It can monitor only FastEthernet and GigabitEthernet port types.
C. The entire EtherChannel must be monitored.
D. Traffic through a destination port can be copied and included in the SPAN session.
E. It can monitor ingress and egress traffic

A and E
