-
what are the three components of SNMP environment is comprised of
- network management station (NMS)
- management node
- management information base (MIB)
-
what does NMS stand for

-
what are traps
traps are unsolicited messages sent by the SNMP agent using port 162 in order to notify the NMS of certain error conditions
-
what is unsolicited messages sent by the SNMP agent using port 162 in order to notify the NMS of certain error conditions
traps
-
what two new protocol operations does SNMPv2 also define
-
what is getbulk define by SNMPv2
- getbulk operation is used by the NMS to efficiently retrieve large blocks of data, such as multiple rows in a table
- getbulk fills a responsemessage with as much of the requested data as will fit
-
what is inform define by SNMPv2
- the inform operation allows one NMS to send traps information to another NMS and to then receive a response
- if the agent responding to getbulk operations cannot provide values for all the variables in a list, it provides partial results
-

FF:FF:FF:FF:FF:FF
-
what does ASIC stand for
application specific intgrated circuitry
-
what does CAM stand for
content addressable memory
-
a switch will flood what type of frames
- broadcasts
- multicast
- unknown unicast
-
what are the three primary forms of switch frame transmission
- store and forward
- fragment free
- cut-through
-
which of the primary forms of switch frame transmission is the slowest
store and foward
-
which of the primary forms of switch frame transmission is fastest
cut-through
-
what is a broadcast storm
a broadcast storm is the endless flooding of a broadcast frame by switches in the network
-

- multicast
-
what are the different types of a broadcast at layer 3
- limited broadcast
- directed broadcast
-
a multicast at layer 3 destination IP address will be what
a class D address
-
information a router has regarding the existence of networks and their locations is stored where in the router's memory
routing table
-
what are the two ways that routers learn about the existence of networks are
-
what is statically learned routes
these "static" entries must be managed and maintained by the network administator
-
what are dynamically learned routes
- routers can learn about the existence of other network through advertisements sent from neighboring routers
- this accomplished by enabling a "routing protocol" on the router and its neighbors
-
what is learned by the router when a network administrator manually configures it
static routes
-
what is routers that can maintain directly connected networks, static routes, and dynamic routes in its routing table simultaneously
administrative distances
-
what is the range of administrative distance
0-255
-
when using a dynmaic routing protocol, it is not uncommon for multiple paths to exist to a destination network defines what
metric characteristics
-
remember
admin always before metric
-

hop count
-
what is often referred to as "routing by rumor"
