Be sure to change the ___________ on your switches
default password
This is what you get when you chop up a broadcast domain and turn it into a bunch of little broadcast domains:
Virtual Lan ( VLAN )
you can use a ________ to connect 2 VLAN’s
router
Higher-end switches offer ____________routing
interVLAN
__________ routing acts like one or more virtual routers to connect multiple VLAN’s
interVLAN
these ports move all VLAN traffic between switches
Trunking
trunking is done by _____________ the ports
tagging, or Port Tagging
_________ is a protocol to allow trunking on certain switches
802.1Q
This is a Cisco proprietary protocol that is used to automate the updating of all VLAN switches
VLAN Trunking Protocol (VTP)
The __________ command displays a switches running configuration
show config
The ___________ command displays the interfaces for all the ports.
show interface
_________ are packets that are smaller than the required ethernet standard
runts
_________ are packets that are larger than the required Ethernet Standard
giants
The ___________ command displays the routing table on a Cisco switch
show route
______ do not use IP addresses or work with Layer 3
switch ports
_______ ___________ use STP to detect looping by deactivating the ports if necessary
Switch interconnections
_____ _______ is a Cisco method allowing only non-switch devices to connect to the switch
BPDU guard
_____ ________ links switch ports to increase bandwidth
Port Bonding
Use _____ for the trunking protocol
LACP
Set port to _________ __________ or _________ __________ or they wont work.
Active - Active
Active - Passive
setting them to just Passive won’t work.
______ ___________ enables the traffic flowing through one port to be monitored on another port
Port mirroring
The ________ ___________ feature enables admins to inspect traffic remotely from a suspect machine
Port mirroring
_________ __________ is configured on a switch by providing a source port and a destination port.
Port mirroring
_______ ___ __________ contols help you better manage available bandwidth
Quality of Service
One type of QoS control is :
traffic shaping
________ _______ on SOHO routers allows you to set priorities for different protocols
Simple QoS
This system switch feature detects and reports possible attacks to the admins
Intrusion Detection Software (IDS)
This switch feature system runs inline with the Network and acts to stop detected attacks.
Intrusion Prevention system (IPS)
A firewall filters, an IDS notifies, an IPS acts to stop.
this is a dedicated box or software
in an organization like schools
caching
has content filtering
acts like a firewall
hides the clients from the server
Forward Proxy Server
this type of proxy doesn’t have to go through a bunch of configuration, has to be inline between you and the internet,
Transparent proxy
this type of proxy is good for High Security
Handles DoS Attacks
Load balancing
Caching
Encryption acceleration
hide the server
Reverse Proxy Server
Load balancing can be done with:
Can route the most available server, either by a configured list
DNS Severs - round robin
Server side - use clustering - uses a sophisticated hardware device that is located within the server.
________ are used to protect public-facing servers by creating and isolated area for those devices.
DMZ’s
Two ________ are used in a DMZ: one allowing unsolicited traffic to public service, and second maintaining isolation of the private network
firewalls
________ _________ can be used to block specific access for areas that may need additional restrictions but, still function within the main domain
Internal firewalls
