Share your SWITCH v2.0 Experience

Congrats @Help me!!!!
I dont suppose you could note which of those you had in the exam for us please?
last day tomorrow!!

You are a star :)

Don’t waste time with LAB LACP / STP … There is a bug in dot1q encapsulation (switchport trunk encapsulation undefined )
Validate the lab with: Sh etherchannel summary and ping 192.168.1.1 from the SWB.
VTP3 and HSRP identical to the ones that are here.

@ Helper thanks great

seems you posted all questions important

@Help me!!!!
Were any of those questions “Check all that apply”? I really hate those.

@MM what do you mean ?

what you want to ask ?

@Boxing_Surfer..

Remember your Q that you labbed about stackwise master?
This seems to

https://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst3750x_3560x/software/release/12-2_55_se/configuration/guide/3750xscg/swstack.html

A stack master retains its role unless one of these events occurs:

The switch stack is reset. (This was an answer)
The stack master is removed from the switch stack.
The stack master is reset or powered off. (this was an answer)
The stack master fails.
The switch stack membership is increased by adding powered-on standalone switches or switch stacks.

@Noor
Some Multiple choice questions won’t tell you how many to pick. Sometimes they say choose 2 or 3. But every now and then you will get a check “All that apply”. So you don’t know how many to select.

@Help me!!

Thanks for your contribution. No one seems to answer this one question i have posted many times.

Can you apply all config under the physical interface?
for example like this:
SW-A(config)#interface range fa0/3 – 4
SW-A(config-if)#no switchport mode access
SW-A(config-if)#no switchport access vlan 98
SW-A(config-if)#switchport trunk encapsulation dot1q
SW-A(config-if)#switchport mode trunk
SW-A(config-if)#switchport trunk native vlan 99
SW-A(config-if)#switchport trunk allowed vlan 1,21-23
SW-A(config-if)#channel-group 1 mode active
SW-A(config-if)#channel-protocol lacp

or you have create the port channel first and do the other half under the logical interface?

@ Help-me

or like this ?

interface range fa0/3 – 4
shutdown
no switchport mode access
no switchport access vlan 98
channel-group 1 mode active
channel-protocol lacp
exit
interface port-channel 1
switchport trunk encapsulation dot1q
switchport mode trunk
switchport trunk vlan native 99
switchport trunk allowed vlan 1,21-23
no shutdown
exit

@ Bez that’s absolutely right, you have to apply that config under the physical interface (not port channel), that’s the requirement in question.

there’s another:

I don’t remember the statement but the configuration is similar to this:

DESCRIPTION ROOM 879
SWITCHPORT MODE ACESS
SWITCHPORT MODE TRUNK
SWITCHPORT ACESS VLAN 700

-voice vlan
-access port
-trunk port
-?
-?

@Help

thanks for clarifying that, really appreciate it. :)

@Switchy

Under which two circumstances does a stackwise master lose is role

A – when a stack master is reset
B – when the priority value of a stack member is changed to a higher value
C – when a switch with a higher priority is added to the stack
D – when a stack member fails
E – when switch stack resets

based on my tests I said
A, C

these two will cause the stack master to come back as something different (member)

those are definitely true.

I think I mentioned that E is a candidate, but if we can only pick two which would you pick?

Passed yesterday 912…Lab was the main big stp portchannel one..and evaluation was hrsp and VTP. Drag and drop was vrrp vs hsrp, vss vs stackwise…most questions are from rspan, vtp, spanning-tree features. And couple of radius and high availability questions.

This is E
– The switch stack is reset

All these options are the same thing really – A
– The stack master is removed from the switch stack
– The stack master is reset or powered off
– The stack master fails.

This is C
– Adding powered-on standalone switches or switch stacks

So I hope this isnt on the exam :)

Help me!!!! – so you never created the port-channel. Did you created vlan 11,12,13?
I also here people saying VTP lab, are they talking about i VTPv3 sim? please can some one confirm?

Please help me answer this..

A network engineer is trying to prevent users from connecting to unauthorized equipment to production environment. Which option can be used campus-wide to satisfy this requirement ?

IP source Guard or BPDU guard

@gok

A network engineer is trying to prevent users from connecting to unauthorized equipment to production environment. Which option can be used campus-wide to satisfy this requirement ?

A lot of people seem to think its IP source guard but I disagree
If you assume the ‘unauthorised equipment’ can get a DHCP IP address then IP source guard wont do anything at all.

For me, unauthorised equipment means network equipment and stuff like that which participates in STP

I would say BPDU Guard is the better choice

@BoxingSurfer, Thank you ! i thought so too.

@Help Me!!!! Are a lot of those questions you posted, questions from the test you took?

https://www.networkcomputing.com/network-security/how-secure-access-switch-ports/page/0/1

whole section on “Why enabling BPDU guard will protect against unauthorized network devices”

Defo BPDU Guard, well spotted

Any one please confirm

87.Which two settings are part of a default LLDP configuration? (Choose two)

-The LLDP global state is disabled

-The LLDP interface state is disabled Or The LLDP interface state is enable

@ CU

You may have to look at the config on switch B to see if these VLANs exist, if not you may need to create them. VTPv3 id the sim

For the last few of use left to take the exam, if you get stuck on a question, dont just guess, great rule is eliminate the ones that make no sense!!
Good luck to you all

Dear’s,

any one confirm, i am not sure about answer

A. It encrypts the password for transmission.
Or
A. It encrypts the password for entire transmission.

##99.Which three feature of AAA with RADIUS are true? (Choose three)
A. It encrypts the password for transmission.
B. It integrates authorization and authentication functions.
F. It secures access to network devices.

@karim

-The LLDP global state is disabled
-The LLDP interface state is enable

To enable LLDP you only need to enable it at the global level

any one please >> correction required here as well

125.Which two statements about GLBP are true? (Choose two)

-The AVG assigns virtual MAC addresses to GLBP group members

-The AVG responds to ARP requests for the Virtual IP address >> AVG or AVF ?

Are the simlets exactly like they are on certprepare? Just a few show commands and its multiple choice?

There is only one real lab on the exam?
