VLANS Flashcards
What is the main characteristic of a flat-network?
One with a single broadcast domain
The admin VLAN is usually assigned which number?
1
What is the default VLAN for all ports?
1
You want to prioritise different types of traffic on a VLAN, what method do you use?
Quality of Service methods
What switch feature can address the below issue?
1) Delay
2) Error
3) Dropped Packets
4) Out-of-order delivery
5) Jitter
QoS
Which is the most secure type of VLAN and why?
Static. The port will always stay on the same VLAN unless manually changed. Whereas in dynamic VLANs the port can change VLAN simply by plugging in a device configured for a different VLAN
You would setup a database of MAC addresses for dynamic VLANs using what?
VLAN Management Policy Server (VMPS)
Access port is what and belongs to what?
is a switch port that has a VLAN configured. Access ports can only belong to one VLAN for data, and one VLAN for voice.
An access-link is what?
the link attaching a access-link device, such as a users computer, to a switch.
Access-link devices know what VLAN they are part of, TRUE or FALSE
False, they just see a single broadcast domain.
How many VLANS can a trunk port carry?
4094
List the devices that use trunk links to connect
1) Switch to Switch
2) Switch to Router
3) Switch to Server
Name the two methods switches use to identify VLANS over a trunk-link?
Inter-switch Link and IEEE 802.1Q
If you had multi-vendor switches interlinked by trunks, which method of VLAN identification or tagging would you employ?
IEEE 802.1Q
How long is the 802.1Q VLAN identifier in a 802.1Q tagged frame?
12-bits
What is the basic goal of VLAN Trunking Protocol? (VTP)
Manage all configured VLANS across a switched internetwork.
For VTP servers to share/manage VLAN informantion, what 4 things are required?
1) VT switches configured on same domain
2) One switch has to be designated the VTP server
3) A VTP password has to be configured
4) No router required
Updated VTP configurations are indicated by what?
Configuration Revision number
Name the 3 VTP modes. Which one isn’t saved in NVRAM?
1) Server
2) Client - not saved in NVRAM
3) Transparent
In VTP Client mode you can add or change VLANs, TRUE or FALSE?
FALSE. Only receive and forward updates to other clients.
Why might you use VTP Transparent mode on a switch?
If you needed a switch that was outside of a VTP domain to forward VTP advertisements to other VTP clients or servers.
What is the default VLAN interface called?
VLAN 1
What is the default gateway setting on a switch used for?
to send management traffic to a remote network for remote monitoring.
What device can replace internal routers on a VLAN architecture to improve performance?
Multilayer switch with its own security features
