What is each VLAN in terms of network traffic?
A separate broadcast domain (separate IP subnet) which is controlled
What must be used to communicate among VLANs?
router
How does VLAN implementation affect network security?
Groups with specific security needs are isolated from the rest of the network
What is a cost reduction benefit of VLANs (select two)? A) Need for expensive hardware upgrades is reduced B) Elimination of all network hardware C) Free software upgrades D) Better use of existing bandwidth and links
A D
How does VLAN reduces unnecessary traffic on each new subnet?
By dividing large, flat Layer 2 networks into separate broadcast domains
What is a key benefit of dividing networks into VLANs in terms of mitigating broadcast storm ?
They prevent a broadcast storm from propagating to the whole network
How does VLAN implementation affect IT staff efficiency?
It makes network management easier, because users with similar network requirements share the same VLAN
In vlans, What is a specific advantage of Having separate functions for simpler project or application management?
It makes working with a specialized application easier For example, an e-learning development platform for faculty

1 and 1002 to 1005
Where are VLAN configurations stored?
In the VLAN database file, called vlan.dat, located in the flash memory of the switch
What is the VLAN ID range specified as the Normal Range, commonly used in small- and medium-sized business and enterprise networks?
1 – 1005
Which VLAN IDs are reserved for Token Ring and FDDI VLANs?
1002 to 1005
What are the two traditional methods of implementing VLANs?
Static or Port-Based and Dynamic
How are VLANs typically configured in Static or Port-Based?
By assigning ports on a switch to specific VLANs.
In the Dynamic method of VLAN implementation, how are VLANs typically configured?
By accessing a Network Management server where the MAC address/VLAN ID mapping is set up by the Network Administrator, and the server assigns a VLAN ID when the device contacts it.
What is the one method of implementing VLANs in Today?
Static

Management VLAN
Which type of VLAN is typically required when an IP phone is plugged to a switch ?
Voice VLAN
