Chapter 11 Flashcards
What is a unmanaged switch
You dont have control over how the switch works beyond what devices to plug in and which ports to use
What is a managed switch
let users adjust each port on the switch to any setting, enabling them to manage, configure and monitor the network in many ways
What is in-band management
When you configure a switch over the network
What is a out-of-band management
Configuring a switch that is outside of your network
what is a jumbo frame
a frame larger than 1500 bytes
What is trunking
The process of transferring VLAN traffic between two or more switches
What is a trunk port
A port on a switch configured to carry all traffic, regardless of VLAN number
What is the 802.1Q standard
The trunk standard, enables you to connect switches from different manufacturers
What is VLAN assignment
The process of assigning ports to a VLAN
What is a static VLANs
VLANs based on ports
What are dynamic VLANs
VLANs based on MAC addresses
What is a 802.1Q tag
a field tacked onto a frames ethernet header enabling the next switch to associate it with the correct VLAN
What is VTP and what does it do
VLAN Trunking Protocol and it allows switches to exchange info to other switches
What happens when you set a VLAN switch to transparent
The switch will not update and will retain the manual settings
What are the only two devices that allow the exchange of data from one VLAN to another
A router or a layer 3 switch- multilayer switch
What is inter-VLAN routing
the process of passing traffic between two VLANs
What does the show config command do
Displays the running configuration
What does the show interface command show
displays the interface for all the ports
What are runts
Packets that are smaller than the required ethernet standard
What are giants
packets that are larger than the required ethernet standard
What does the show route command show
displays the routing table
What is port bonding/ port aggregation
Using two ports on a switch to boost the amount of data that can be transferred
What is port mirroring
When you have a switch send traffic that is happening on a different port to your computer
What is a intrusion detection system (IDS)
detects and reports possible attacks to the admin
What is a intrusion prevention system (IPS)
runs inline with the network and acts to stop detected attacks
What is a firewall
Filters incoming and outgoing traffic
What do forward proxy servers do
Hide the clients from the server by forwarding the message to the server
What does a reverse proxy server do
Hides the server, and can provide load balancing and caching for high activity pages
What can forward proxy servers be configured for
caching, content filtering, and firewall capability
What is load balancing
When a lot of servers distribute the load of traffic in an even way
What are DMZ (Demilitarized Zones) used for
To protect public-facing servers by creating an isolated area for those devices
