SNMP
In network management, what role does SNMP play?
SNMP is used for monitoring and managing devices within a network.
What is a baseline?
A baseline is a report of a network's normal operational state with acceptable measurements.
What is traffic shaping?
Traffic shaping controls traffic flow by regulating the type and amount of data sent across a network or interface.
Identify/list the 6 steps of the incident response process.
- Step 1: Preparation
- Step 2: Detection and identification
- Step 3: Containment
- Step 4: Remediation
- Step 5: Recovery
- Step 6: Review
Which SNMP version is considered the most secure, and list two more characteristics?
SNMP v3 - Also adds authentication and encryption
- Network backbone utilization rate
- Number of users logged on per day or per hour
- Number of protocols running on network
- Error statistics (Runts, jabbers, or giants)
- Frequency of application use
- Bandwidth usage
What is one common QoS mechanism used to prioritize network traffic?
- Protocol
- IP address
- User group
- DiffServ (Differentiated Services)
Differentiate between an accident and a disaster.
An incident is any event that negatively impacts a network’s availability or resources, such as a security breach, infection, or environmental issue. A disaster is a severe incident causing a network outage that affects multiple systems.
List a difference between SNMP v1 and SNMP v3.
SNMP v1 lacks security features, while SNMP v3 includes authentication and encryption for secure communication.
What are two common performance KPIs (key performance indicators)?
- Device availability and performance
- Interface statistics
- Utilization
- Error rate
- Packet drops
- Jitter
Identify and explain the two forwarding DiffServ types.
EF (Expedited Forwarding): Ensures a minimum departure rate for data streams.
AF (Assured Forwarding): Assigns varying resource levels to data streams.
What is business continuity?
Business continuity is a company's ability to keep operations running with minimal disruption.
What is NMS, and explain the process of polling?
NMS is network management system - Polling is the collection data from multiple managed
devices at regular intervals.
What do baseline measurements serve as?
Baseline measurements serve as a basis of comparison for future performance increases or
decreases caused by network changes with past network performance.
Explain the difference between traffic shaping and traffic policing.
Traffic shaping smooths traffic by delaying packets to conform to a specified rate. Traffic policing enforces momentary limits during a specified time period.
Identify two things that should be included in a disaster recovery plan.
- Contact information for emergency coordinators
- Information on data and server backups, including frequency, storage locations, and recovery procedures
- Network topology, redundancy details, and agreements with service carriers
- Regular disaster recovery plan testing strategies
- A crisis management plan
