how many versions of SNMP are there?
3
what is a baseline?
the report of a networks normal state of operation
known as techniques used to adjust the priority a network assigns to various types of transmissions.
QoS (Quality of Service)
what is an incident response plan?
the characteristics of an incident and the steps that are followed
which version of SNMP is least used?
SNMPv1
what is a kpi?
key performance indicator
which two transmissions are considered delay sensitive?
voice and video
do the 6 steps of incident response occur before or after an incident happens?
before
what is the most secure version of SNMP?
SNMPv3
Frequency of application use and bandwidth usage are both examples of what?
Network performance baselines
limiting traffic volume flowing in and out of interface during specified time period, limiting momentary throughput rate for an interface are known as what?
Traffic policing
what is step one of the 6 steps of incident response?
preparation
which 4 enterprise-wide network management systems work together in SNMP communications/
NMS, managed device, Network management agent and MIB
what serve as a basis of comparison for future performance increases or
decreases caused by network changes with past network performance?
Baseline measurements?
what refers to techniques performed at layer 2 on Ethernet frames
what is the difference between an incident and disaster?
an incident has a minor effect to a networks ability and a disaster is a severe effect to a networks ability.
Explain what each version of SNMP.
SNMPv1: the original and is barely used
SNMPv2: an improved version of SNMPv1 with added security and performance
SNMPv3: an improved version of SNMPv2 with the addition of authentication, validation and encryption
what are three things KPI's can include?
any 3 of: device availability and performance, interface statistics, utilization, error rate, packet drops, jitter
what are two possible techniques used to prioritize traffic?
any of the two: Protocol, IP address, User group, DiffServ (Differentiated Services) flag in an IP packet, VLAN tag in Data Link layer frame, Service or application
what are the 6 steps of incident response in order?
preparation, detection and identification, containment, remediation, recovery, review
