What are performance metrics in networking?
Quantitative measures like bandwidth, latency, jitter, and packet loss used to evaluate network performance.
What is bandwidth as a performance metric?
The maximum data transfer rate of a network
What is latency as a performance metric?
The time it takes for data to travel from source to destination
What is jitter as a performance metric?
Variation in latency between packets
What is packet loss as a performance metric?
The percentage of packets sent but not received
What is SNMP?
Simple Network Management Protocol
What is an SNMP agent?
Software on a managed device that collects performance data and sends it to an SNMP manager.
What is an SNMP manager?
A system that queries SNMP agents
What is an MIB in SNMP?
Management Information Base
What is the role of logs in network monitoring?
Logs record events like errors, access attempts, and performance issues, aiding in troubleshooting and auditing.
What is syslog?
A protocol for collecting and storing log messages from network devices
What is network monitoring?
Continuously observing network performance and security using tools like SIEM or SNMP to detect issues.
What is a baseline in network monitoring?
A snapshot of normal network performance
What are network plans and procedures?
Documented processes for network operations
What is a change management plan?
A procedure to plan
What is an incident response plan?
A process for identifying
What are network security policies?
Rules and guidelines to protect network integrity
What is an acceptable use policy (AUP)?
Defines permissible uses of network resources
What is a password policy?
Specifies requirements for password strength
What is a data loss prevention (DLP) policy?
Prevents unauthorized access or transmission of sensitive data
What is network documentation?
Records of network configurations
What is a network diagram?
A visual representation of network devices
What is an IP address inventory?
A list of assigned IP addresses
Why is network documentation critical?
Ensures consistency, speeds up troubleshooting, and supports compliance with regulatory requirements.
