CCNP Switch Chapter 5 Exam Questions with Correct Answers |New Update
100% Verified By Experts
What does VTP do? The VLAN Trunking Protocol (VTP) uses Layer 2 trunk frames to
communicate VLAN information among a group of switches. VTP manages the addition,
deletion, and renaming of VLANs across the network from a central point of control
What are VTP management domains? VTP management domains are areas with common
VLAN requirements. A switch can belong to only one VTP domain. And if switches are not part
of the same domain, they won't share VTP information
What are VTP advertisements? VTP advertisements are messages that contain information
about the VTP management domain, VTP revision number, known VLANs, and specific VLAN
parameters. They are only sent over trunks.
What are the different VTP modes? - Server mode
- Client mode
- Transparent mode
What is VTP Server mode? It's the default VTP mode. In VTP server mode, the switch has full
control over VLAN creation and modification for their domains. All VTP information is
advertised to other switches in the domain, while all received VTP information is synchronized
with the other switches.
What is VTP Client mode? VTP clients listen to VTP advertisements from other switches and
modify their VLAN configurations accordingly. They are in passive listening mode. Received VTP
information is forwarded out trunk links to neighboring switches in the domain, so the switch
also acts as a VTP relay. Clients can't create, change, or delete VLANs.
What is VTP Transparent mode? Switches in VTP Transparent mode don't participate in VTP.
They don't advertise their own VLAN configurations and they don't synchronize their VLAN
databases with received advertisements.
, How many switches do you need to have in VTP server mode? You need to have at least one
VTP server in each VTP domain so that VLANs can be created, modified, or deleted, and VLAN
information can be propagated. Only one VTP server should create and configure VLANs.
What is the difference between how switches in VTP Transparent mode operate between
version 1 and 2? - In version 1, the switch doesn't relay VTP info it receives to other switches
unless its VTP domain names and version numbers match.
- In version 2, transparent switches do forward received VTP advertisements out of their trunk
ports, acting as VTP relays regardless of the domain name.
Where can a switch in VTP transparent mode create and delete VLANs? Creations and
deletions only are implemented locally. The changes won't be propagated to other switches
What VLANs do switches include in VTP advertisements? only VLANs from 1 to 1005
How are VTP advertisements sent and received? VTP advertisements are sent as multicast
addresses and they are received by a switch's supervisory processor. They are forwarded out
trunk links as a special case
Can you use a password to encrypt and decrypt VTP advertisements? Yes, but by default,
the management domains are set to use nonsecure advertisements... the same password must
be configured on all switches in a domain.
What is a VTP configuration revision number? It's an index used to keep track of the most
recent VTP information. It always starts with configuration revision number 0 and it increments
when subsequent changes are made.
What happens if a switch that is part of a VTP domain receives an advertisement with a greater
revision number than is stored locally? it overwrites the previously stored VLAN information
