Flashcards in Network+ Chapter 11 Deck (19):
What are 4 benefits of Layer 2 switching?
Hardware-based bridging (ASIC)
what are 3 functions of Layer 2 switches that you will need to remember?
Forward/ filter decisions
Define Address Learning?
Layer 2 Switches remember the source hardware address of each frame received on an interface and enter this information into a MAC database known as a forward/ filter table.
Why is it good to have redundancy between switches?
Having redundancy between switches can help prevent complete network failures if one should fail.
What are the 5 methods the ports on a bridge or switch running STP can transition through?
Whare are the 5 QoS methods problems that can affect data as it traverses network cable:
Why would you create a static VLAN?
static VLANs are the most secure.
Static access ports are either manually assigned to a VLAN or assigned through a________ server for use with ________.
What two speeds can a trunk link run at?
100Mbps or 1000Mbps
How many VLANs can be carried across traffic at once?
1 to 4,094
Describe VLAN Trunking Protocol (VTP)?
Its to manage all configured VLANs across a switched internetwork and to maintain consistency throughout that network.
What are 4 features that VTP has to offer?
Consistent VLAN configuration across all switches in the network
Accurate tracking and monitoring of VLANs
Dynamic reporting of added VLANs to all switches in the VTP domain
Adding VLANs using plug-and-play
What are 4 requirements for VTP to communicate VLAN information between switches:
The VTP management domain name of both switches must be set the same.
One of the switches has to be configured as a VTP server.
Set a VTP password if used.
No router is necessary and a router is not a requirement.
____________is a way of explicitly tagging VLAN information onto an Ethernet frame.
Inter-Switch Link (ISL)
What does it mean when you configure a switch out-of band?
you aren't going through the network to configure the device. You are actually using a port to configure the switch instead.
What kind of environment would you use a unmanaged switch in?
What is a unmanaged switch?
They are basic plug-and-play switches with no remote configuration, management, or monitoring options
Define Dynamic ARP inspection (DAI)?
Its a feature that uses the DHCP snooping database of IP address to MAC address mappings to verify the MAC address mappings of each frame going through the switch.
