SOLARWINDS CERTIFIED NETWORK MANAGEMENT
PROFESSIONAL
What are the two types of network management protocols? - Answer- query-based and
event-based
Give examples of event-based network management protocols. - Answer- SNMP traps,
Syslog
What's the best practice regarding query-based and event-based net mgmt protocols? -
Answer- - use both types, and configure reports for each of them
- tune the polling frequency
- tune the granularity
true/false: Orion does only fault monitoring. - Answer- false: it does performance
monitoring too
FAlut Monitoring in Orion is done through which protocols? - Answer- ICMP and SNMP
Give characteristics of query-based net mgmt protocols. - Answer- - can be scheduled,
- the NMS queries the nodes regularly, so it's reliable
- specific
Give characteristics of event-based net mgmt protocols. - Answer- - the NMS is
passively listening to events, so it's unreliable
- fast
- details are configurable
What are the two elements of Fault Monitoring? - Answer- device status, sub-element
status
Give some elements of performance monitoring and the corresponding protocols that
they use - Answer- - Latency => ICMP
- statistics (CPU, memory, traffic, errors,..) => SNMP
- Windows statistics => SNMP and WMI
What's the default port and protocols of SNMP polling? - Answer- UDP/161
in Orion NPM Top 10 List page, how is data collected? - Answer- with SNMP
Under Orion NPM Device Details page, what type of data can we find? - Answer- for
each device listed: CPU, memory, buffer, interface status...
all these data are collected with SNMP
, true/false: Orion puts 110 in the data field of an ICMP packet - Answer- false. The data
field is empty. Some firewalls do not allow these packets by default.
true/false: Orion can configure different SNMP transport protocol and port per device -
Answer- true
What's the acronym for MIB? - Answer- Management Information Base
What's the acronym for OID? - Answer- Object IDentifier
What's an MIB? - Answer- a collection of OIDs that describe data on a device. Each
NMS comes with a collection of manufacturers' MIBs. If the desired MIB is not there,
you can download it and include it to the NMS
What are the most commonly used MIBs? - Answer- System MIB and Iftable MIB
Where can we find documents that describe MIBs? - Answer- at ietf.org, as RFCs
What's Perfmon? - Answer- a set of Windows performance monitoring counters. It's
different from SNMP
What are the net mgmt methods? - Answer- Ask, Hire an Agent, Delegate
Which are the primary types of MIB? - Answer- Status, Rates, Counters
Define MWI - Answer- - is used for managing Windows applications,
- is extensible to custom applications,
- is like using Perfmon remotely,
- runs on Windows only
What is a TCP-based application check? - Answer- it's when NMS tries to connect to
applications on their native ports (eg; FTP-21, mail sever-25, http-80)
Describe SNMP traps - Answer- run on UDP/162, the device "shouts out" a message to
NMS. This latter interprets it using MIB. - fast - unreliable
Describe Syslog - Answer- - originally designed for Unix Systems
- supported by network devices
- runs on UDP/514
What are the types of agents in the "Hire an Agent" method? - Answer- there are two
types of agents: basic and manufacturer-provided
Give examples of basic agents - Answer- SNMP agent, WMI agent. These agents are
installed by default
