Which Two Statements About VTP Are True?
Configure and verify VLANs (normal range) spanning multiple switches
Configure and verify interswitch connectivity
Answer
Correct answer: A, E — every switch in a VTP domain must use the same VTP domain name and the same VTP version.
Which two statements about VTP are true? (Choose two.)
Community Insight
The question tests the mandatory VTP domain parameters, and the trap is picking the revision-number statement (D) instead of the same-version requirement (E) that Cisco's configuration guidelines explicitly list.
VTP (VLAN Trunking Protocol) synchronizes VLAN databases across switches only inside a properly defined domain. This page establishes that the two true statements are that every switch must share the same VTP domain name and the same VTP version, while trunk negotiation, unique domain names, and server revision-number rules are incorrect.
Option D is the most tempting wrong pick: learners assume the VTP server must hold the highest configuration revision, but revision is a per-switch counter and any client with a higher revision will overwrite the server's VLAN database.

D is an incorrect statement.. VTP dont require the server to have the highest revision number. Instead, switches use the configuration revision number to determine which VLAN database is newer..

VTP version and VTP configuration revision number are two different things. The VTP version is the version of the protocol used by the switch, for example VTP v1, v2, or v3. It does not change every time you make a configuration change. The configuration revision number is a counter that tracks changes made to the VLAN database.

Some key rules for VTP: All switches in the same VTP domain must share the same domain name. All switches in the VTP domain should run the same VTP version. VTP servers propagate VLAN changes based on revision numbers. Trunking is necessary for VTP to propagate VLANs, but switches don’t have to negotiate trunks manually—VTP just requires a trunk exists.

“All switches in a VTP domain must use the same VTP domain name. The VTP configuration with the highest revision number overwrites all others in the domain.” E its not because:“All switches must use the same VTP version” is not always true VTP version compatibility depends on the network: VTPv2 is compatible with VTPv1 (can coexist). VTPv3 can operate with earlier versions but requires manual configuration and additional features. So, while using the same version is recommended, it’s not a strict requirement like the domain name is.

I think D is confusing. It says MUST have highest revision number, were the revision number can be the SAME as the other switches. For example, two out of the box switches at default settings will have the same revision number, but can still be configured in the same vtp domain. Version has to be the same, as Cisco docs. If the version is not the same the switch will auto adjust to match the compatible vtp version. https://www.cisco.com/c/en/us/support/docs/lan-switching/vtp/98154-conf-vlan.html#toc-hId--1506281683

VTP Domain Name: For switches to share VLAN information via VTP, they must be in the same VTP domain. This means that all switches that need to exchange VLAN information must be configured with the same VTP domain name. VTP Version: To ensure compatibility and proper operation, all switches within a VTP domain must be using the same version of VTP. Different versions of VTP (e.g., VTPv1, VTPv2, VTPv3) are not compatible with each other.

A Correct - The VTP domain name has to be the same on both switches. Cisco switches participating in VTP are organized into management domains, or areas with similar VLAN requirements. All switches in a VTP domain must have the same Domain Name E Correct - VTP versions have to match between the switches1. Three VTP versions are available – V1, V2, and V33. D - Tricky but it's the other way around for me. Whichever VTP device has the highest Rev No is the VTP 'Server' In a VTP domain, the switch with the highest VTP configuration revision number determines the VLAN configuration for that domain. This means that if a switch (be it a VTP server or client) with a higher revision number is introduced to the network, its VTP information will overwrite the existing VTP information in the domain. This is true regardless of whether the switch with the higher revision number is a VTP client or server. My question to Copilot 'in vtp does the vtp server have to have the highest revision number in the domain?'

VTPv3 is compatible backwards with VTPv2, son E is not correct. Then, if you want that the switches work each other, VTP domain name must be the same. Finally, if you have a new swithc in the VTP domain with a higher revision number, it won't use the configuration provided by the VTP server

A. All switches must be configured with the same VTP domain name: For VTP to work correctly, all switches in the same VTP domain must have the same VTP domain name. This is necessary to ensure that they exchange and synchronize VLAN information. E. All switches must use the same VTP version: To avoid compatibility issues, all switches in the same VTP domain should use the same VTP version (VTPv1, VTPv2, or VTPv3). Using different VTP versions can lead to inconsistencies in VLAN configuration.

Option A, All switches must be configured with the same VTP domain name , is true since VTP operates within a domain, and all switches in the domain must have the same VTP domain name in order to exchange VLAN information. Option B, All switches must be configured to perform trunk negotiation , is false, as switches can operate with VTP without being configured in trunk mode. Option C, All switches must be configured with a unique VTP domain name , is also true since VTP domain names must be unique in order to prevent VLAN misconfigurations. Option D, The VTP server must have the highest revision number in the domain, is false, as the VTP device with the highest configuration revision number becomes the master or server. Option E, All switches must use the same VTP version, is false, as switches can operate with different VTP versions, although it's better to keep them the same to avoid any possible compatibility issues. Therefore, the correct answers are AC

This is such a difficult question. My vote is A and E, and here is why: If all switches in a VTP domain don't have the same domain name and version number, then VTP literally will not function. You cannot argue that "the VTP domain doesn't need to be the same because there could be multiple domains on the network" without in turn acknowledging that those separate domains could then also be running different versions of VTP. On the other hand, if another switch with a higher revision number happens to be brought into the VTP domain, yes, the VTP servers will rewrite their table and things will get messed up, but VTP itself still technically functions.

Expert Analysis
Why the Answer Is Correct
Option A is correct because VTP advertisements are only processed by switches that share an identical domain name; a mismatched name makes a switch appear to be outside the domain, so VLAN updates are simply ignored. Option E is correct because Cisco's official VTP configuration guidelines state that all switches in a VTP domain must run the same VTP version, and a version mismatch prevents VTP messages from being interpreted consistently across the domain. Together, matching domain name and matching version are the two prerequisites that allow a VTP domain to exchange VLAN information at all. Both requirements appear verbatim in Cisco's published VTP configuration guideline lists.Why the Other Options Are Wrong
Option B is wrong because VTP does not depend on DTP trunk negotiation; VTP runs over trunks that can be statically configured, and Cisco notes that trunk negotiation does not even work across separate VTP domains. Option C is the direct opposite of the documented requirement and would fragment the network into isolated single-switch domains where no VLAN propagation occurs. Option D is wrong because the configuration revision number is a per-switch monotonically increasing counter, not a server attribute: whichever switch holds the highest revision wins the exchange, which is precisely why a client or a freshly introduced switch with an inflated revision can overwrite a server's VLAN database — a classic VTP misconfiguration hazard. Nothing in VTP mandates that the server hold the top revision value.Community Comment Notes
Several learners converged on A and E, with iMo7ed quoting the guideline that "All network devices in a VTP domain must run the same VTP version" and Equiano stating "AE should be the only two correct answers here." IxlJustinlxl pasted Cisco's guideline list covering same domain name, same version, same password, and server revisions. Rob2000's note that switches share a domain name "UNLESS the network design insists for different VTP domains" actually describes deliberately separate domains, not a reason to avoid option A. ricky1802 argued version need not match, but this contradicts the cited Cisco guideline text, while creaguy rightly warned: "Lets not get confused with VTP version and revision."Official Reference
Exam Strategy
Treat VTP questions as guideline-recall items: memorize Cisco's VTP configuration checklist (same domain name, same version, same password, correct revision handling). When two options look plausible, eliminate any statement using "must" that describes a design choice rather than a protocol requirement, such as unique domain names or highest server revision.
Frequently Asked Questions
Why is "the VTP server must have the highest revision number" not a true statement?
The configuration revision is a per-switch counter, so whichever switch holds the highest revision wins the exchange regardless of its role. That is why a client with an inflated revision can overwrite a server's VLAN database.
Does VTP require DTP trunk negotiation on every link?
No. VTP advertisements flow over trunk links that can be statically configured with switchport mode trunk; Cisco even notes trunk negotiation does not work across different VTP domains.
