Share your SWITCH v2.0 Experience

Don’t buy any dump, passed today, i share materials, i use to prepare,
the same thing, lacp stp, 2dnd: VSS vs stack, radius,vrrp, hsrp,
pay attention to the int in hsrp lab, vtp, a little changed than what is here,
dump oct is valid, pass at least three times

An engineer needs to add a customer private VLAN to the network. What configuration is required to isolate the customer’s traffic on the network?
A. Configure transparent mode
B. Enable VTP v3
C. Configure VTP in server mode
D. Disable VTP and manually configure the customer VLAN

why do people assume the answer involves ‘Transparent mode’ for these questions?
If VTP v3 is an option I think its a better choice…

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

The answers are:
True:
MAC address learning is disabled
Uses VLAN ID 2-1001
Supports only VTP

False:
Uses VLAN ID 2-1024
Supports only STP

@RSPAN

can you explain why you classify the STP option as false in this case?

Etherchannel – can you share your dump
ct 2320 at gmail.com –thanks

@boxingSurfer

The negative statements in the STP description for RSPAN make the “ONLY” part of the statement false.

STP—A destination port does not participate in STP while its SPAN or RSPAN session is active. The destination port can participate in STP after the SPAN or RSPAN session is disabled. On a source port, SPAN does not affect the STP status. STP can be active on trunk ports carrying an RSPAN VLAN.

The VTP statement does not have the same negative statements.

VTP—You can use VTP to prune an RSPAN VLAN between switches.

With there being 3 true options and 2 false, that is the only option. This is a bad question and I hope it doesn’t show up on the test anymore. Because technically, using the word “ONLY” in the statement actually makes them both false, but we know 100% that 2-1001 is true, so the only statements have to be split.

I have valid spoto 355 q dump + 21 Valid D&D, used by myself for passing SW exam. The dump has 15 new questions that re not in any dump like certprepare, IPhelper or Chinese.

If you are interested contact me at dams.vce1290 AT gmail DOT com.

Good luck!

Which dump you studied. Certprepare?
Part 6,7,8 only or all category questions and
Composite quiz ?
Please let us know

@Spoto Dump

Can you post the new questions here if you think they are new?

@Aevin

@RPSAN
Thanks, i am in agreement, thats also what i will choose in the exam.
I always thought that the vlan ranges and the “only” statements should be split between true/false or it doesnt make any sense!

@Switchy

I got that thanks.

Did you notice how wrong the PortFast / BPDUGard / BPDUFilter one was?

This one mate?

PortFast
-Configured on access ports with a single host device (correct)
-Configured trunk interface goes immediately to forwarding state from blocking state (correct)

BPDU Guard
-Protects configured interface from receiving unauthorised BPDU frames
-Shuts down port and places it in err-disabled mode (correct)

BPDU Filter
-Disables Spanning Tree on a configured interface (correct)
-Protects configured interfaces from sending and receiving unauthorised BPDU frames

PortFast
– Configured on access port > single host device
– configured trunk interface > immediately fwding from blocking

BPDU Guard
– Shutdown port / err-disable
– Protect from recieving unauthorised BDPUs

BPDU Filter
– disables spanning tree
– configues interface from send and receive BPDUs

they seem the same?
do the 2 for each have to be also in the right order top then bottom?

@Switchy – yeah that one :)

Im just going to Lab this one, but I think i already know the answer

In which two ways are IEEE STP BPDUs forwarded if VLAN 99 is configured as native? (Choose two)
A. VLAN 1 STP BPDUs are sent tagged on VLAN 1
B. VLAN 1 STP BPDUs are sent tagged on VLAN 99
C. VLAN 1 and VLAN 99 BPDUs are sent tagged on VLAN 1
D. VLAN 1 STP BPDUs are sent untagged on VLAN 1
E. VLAN 1 STP BPDUs are sent untagged on VLAN 99

I think the answer is A and D

i think i would pick A and E

I was right though :p

its A and D

@ homer’s dump shame on you and those same others like you

still trying to selling dumps you beggar
go to streets and start begging better for you

A. VLAN 1 STP BPDUs are sent tagged on VLAN 1
B. VLAN 1 STP BPDUs are sent tagged on VLAN 99
C. VLAN 1 and VLAN 99 BPDUs are sent tagged on VLAN 1
D. VLAN 1 STP BPDUs are sent untagged on VLAN 1
E. VLAN 1 STP BPDUs are sent untagged on VLAN 99

Answer A & E

@ Spoto Dump >> shame on you

Better go to market and streets start begging better for you.

dont be spamer and worms for other who preparing exam and helping to pass it

SW-A and SW-B
– 4 VLANs (VLANs 1, 10, 50, 99) configured
– Static trunking. Native vlan set to 99 on both
– Spanning tree mode PVST+ (ieee) on both
– SPAN session monitoring the trunk interface
– Wireshark filtering STP

with this setup I see the following types of frames
IEEE (dest mac 0180:c200:0000)
PVST (dest mac 0100:0ccc:cccd)

> IEEE BPDU isnt vlan aware. No tags ever seen on these frames
> PVST BPDU tagged vlan 1
> PVST BPDU tagged vlan 10
> PVST BPDU tagged vlan 20
> PVST BPDU untagged

Hey guys we can make a group and by spots.net dump
Which is around $150 . I already contacted them . They have
Only 384 MCQ and they said it is valid . If we can make a group
And buy it is affordable for everyone , rather paying for these cheating
Seller on this comment section

@Switchy,@karim
Sorry you’re both right, and I’m wrong

> PVST BPDU tagged vlan 1 (VLAN 1 STP tagged on VLAN 1)
> PVST BPDU untagged (VLAN 99 STP untagged)

Im being an idiot

@ Boxing i m still confused
question
which two task must you perform to enable dhcp option 82 on an untrusted port

can you please place correct answers sure this will be in exam

@Karim

which two task must you perform to enable dhcp option 82 on an untrusted port?

(config)#ip dhcp snooping information option allow-untrusted
(config-if)#ip dhcp snooping information option allow-untrusted

its exactly the same command in either global or interface config, depending on where you want to apply it

means correct answers are

enter ip dhcp snooping information option allowed untrusted comanad to enable untrusted port

enter ip dhcp snooping information option command to enable option 82

How about this one guys?

Which two statements about 802.1q are true? (Choose two.)
A. It encapsulates the original Ethernet frame and adds a VLAN identifier.
B. It increases the maximum size an Ethernet frame to 1594 bytes.
C. It is a Cisco proprietary protocol.
D. When It is enabled, it forces a recalculation of the frame check sequence field.
E. It supports 8-byte VLAN identifiers.
F. It adds a 32-bit field to the Ethernet frame between the source MAC address and length fields

A. It encapsulates the original Ethernet frame and adds a VLAN identifier.
– incorrect. 802.1q adds a tag field into the original frame. It doesnt encapsulate the frame

B. It increases the maximum size an Ethernet frame to 1594 bytes.
– incorrect. max is 1522

C. It is a Cisco proprietary protocol.
– incorrect. its and IEEE standard

E. It supports 8-byte VLAN identifiers.
– incorrect. It adds a 4 byte tag

These two are the remaining true ones
D. When it is enabled, it forces a recalculation of the frame check sequence field.
– true. the modification of the original frame requires the FCS to be recalculated

F. It adds a 32-bit field to the Ethernet frame between the source MAC address and length fields
– 4 bytes is 32 bits, and it is placed between the SA-MAC and TYPE/LEN fields

@karim

(config)#ip dhcp snooping information option

This command enables the insertion of option 82 field when DHCP is enabled, yes.

Its global config only this one. I think its on by default.

@karim

(config)#ip dhcp snooping information option

This command enables the insertion of option 82 in DHCP message when DHCP snooping is enabled, yes.
