Internet Protocol Analysis/Network Monitoring/Quiz

{ Network monitoring describes the use of a system that { constantly monitors a computer network for slow or failing components (i) _71 } and that { notifies the network administrator (via email, SMS or other alarms) in case of outages (i) _88 }.

{ Simple Network Management Protocol (SNMP) is an Internet-standard protocol for { managing devices on IP networks (i) _33 }. With SNMP, administrative computers called { managers (i) _10 } monitor or manage a group of hosts on a computer network. Each managed system executes an { agent (i) _7 } which reports information via SNMP to the manager.

{ SNMP uses a { Management Information Base (MIB) (i) _35 } to describe the structure of the management data of a device subsystem. The { MIB (i) _5 } is a hierarchical namespace containing { object identifiers (OID) (i) _26 }, and each { OID (i) _5 } identifies a variable that can be read or set via SNMP.

{ SNMP is an { application (i) _13 } layer protocol. SNMP { agents (i) _8 } receive requests on { UDP (i) _5 } port { 161 _5 }. SNMP { managers (i) _10 } receive notifications on { UDP (i) _5 } port { 162 _5 }.
 * type="{}" coef="7"}

{ SNMP messages from managers include { GetRequest, SetRequest, GetNextRequest, and GetBulkRequest (i) _60 }. SNMP messages from agents include { Response and Trap (i) _19 }. SNMP messages from manager to manager include { InformRequest (i) _15 }.

{ SNMP versions 1 and 2 support limited security through the use of a clear-text password known as a { community string (i) _18 }. SNMP version 3 supports encryption on { UDP (i) _5 } ports { 10161 _7 } and { 10162 _7 }.
 * type="{}" coef="4"}

{ Default SNMP settings present a variety of { security issues (i) _17 } that must be addressed when SNMP is implemented on a network.
