To prevent the VLAN database from being corrupted when adding an old switch back into the network, the switch should be added to the VTP domain with a lower revision number. VTP (VLAN Trunking Protocol) configurations use the VLAN configuration with the highest revision number within the domain. Therefore, if a switch with a higher revision number is added, it could overwrite the existing VLAN configurations on other switches. Adding a switch with a lower revision number ensures that it will adopt the current VLAN configuration from the network without causing disruptions.
One danger of VTP: If you connect an old switch with a higher revision number to your network (and the VTP domain name matches), all switches in the domain will sync their VLAN database to that switch.
Ref: VTP Client and revision numbers - Cisco Community Post by balaji.bandi “… Adding a VTP Client Switch to a VTP Domain Before adding a VTP client to a VTP domain, always verify that its VTP configuration revision number is lower than the configuration revision number of the other switches in the VTP domain. Switches in a VTP domain always use the VLAN configuration of the switch with the highest VTP configuration revision number. …” A. Add the switch in the VTP domain with a lower revision number. Correct answer. B. Add the switch in the VTP domain with a higher revision number. Wrong answer. C. Add the switch with DTP set to dynamic desirable. Wrong answer. D. Add the switch with DTP set to desirable. Wrong answer.
VTP is not part of CCNA 200-301
Did you already certificate?
whether A or B, The switch has to have the lower revision number, not the VTP domain. They should have used more words to make that clear. Likely the answer is A because if you're putting in a switch, you're going to do it regardless of what the VTP domain is currently set up as. and so, the "with a lower revision number" likely refers to the switch.
exactly, that's why i got confused between "A" and "B" because of the selection of the words.
Why are people answering B? Answer is A.
Answer is B Please read the question carefully. The question is pertaining to the old switch from corrupting the VLAN database. It needs the highest revision number in order to prevent from corrupting the VLAN database.
if you put a switch with higher revision number will f...k up the database of the other switches, if you put a switch with lower revison number, it will update the database according with the other swithces
Absolutely not! You're on drugs. Two ways to prevent network breakdown: a). change VTP domain to an unused domain, will reset the REVISION number to ZERO. b). Change the VTP mode to transparent in order to reset the REVISION number to ZERO.
A is correct
A is correct
A is right because you don't want to mess the database up
ANSWER B I highly suggest you implement some kind of vtp configuration to prevent this in the future. Adding a switch with a higher revision can easily wipe out the vlan configuration on the remaining switches and perhaps that's exactly what happened https://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst3750/software/release/12-2_40_se/configuration/guide/scg1/swvtp.html
Just so hard to even understand the question, even before you get into the curriculum! You can read the question 2 ways. But the key for me is that you DONT add an old switch into the network/ domain with a higher revision number than the 'VTP server' So if you read the Question as, 'Add the switch with a lower revision number into the VTP domain', then its A If you read, 'lets make sure we add the switch with rev no (x) to the domain with the highest VTP revision (y) and hope (y) is higher than (x)!!', then its B Id be going B in the exam....

B Caution Before adding a VTP client switch to a VTP domain, always verify that its VTP configuration revision number is lower than the configuration revision number of the other switches in the VTP domain. Switches in a VTP domain always use the VLAN configuration of the switch with the highest VTP configuration revision number. http://www.securecisco.com/TMCCcisco1234F12/StudyGuide/ccna3/Info/revision.number.htm
This source verifies that the correct answer is "A". Did you type wrong or did you misunderstand the source?
Wording error on my part. A is correct. Thanks
In real life you would just put a switch in transparent mode...
