SNMP Versions
What does SNMP stand for?
Simple Network Management Protocol
What is a network baseline?
A baseline is a report of the network’s normal state of operation and might include a range of acceptable measurements.
What does QoS stand for?
Quality of Service
What is the first step in the incident response process?
Preperation
Which SNMP version introduced encryption?
SNMPv3
Why is establishing a baseline important?
Baseline measurements serve as a basis of comparison for future performance increases or decreases caused by network changes with past network performance
Name one method used to implement QoS.
Traffic shaping, traffic policing, traffic prioritization, DiffServ, CoS, PCP
What is the purpose of the containment step?
To make sure the problem does not spread and isolate it.
Describe a key difference between SNMP v1 and v3.
SNMP v1 is not as fast or secure as v3.
How often should a network baseline be reviewed?
At least monthly
Why is QoS important for VoIP applications?
QoS prioritizes reduces packet loss, latency, and jitter in VoIP by prioritizing it over other traffic.
Describe the remediation step.
The remediation step is when the problem is removed or otherwise fixed.
What are the security features of SNMP v3?
Authentication, validation, and encryption
What tools can be used to establish a network baseline?
Netflow and sFlow
Explain the difference between traffic shaping and traffic policing.
Traffic shaping sends traffic in a steady stream of data, while traffic policing drops packets that exceed the max.
Why is the review step important?
The review step in lets the organization see how they managed the problem and improve protocol for next time.
