Term 32
NetFlow Configuration is the process of setting up Cisco devices to collect and export metadata about network traffic flows for monitoring, analysis, and troubleshooting.
Term 33
The NTP (Network Time Protocol) Client and Server are roles in a time synchronization system where the server provides accurate time to clients, ensuring all devices on a network share the same precise clock.
Term 34
OSPF and EIGRP authentication is a security feature that verifies the identity of routers exchanging routing updates, ensuring only trusted devices can participate in the network.
Term 35
OSPF authentication is a security mechanism that verifies the identity of routers exchanging routing information within an OSPF network, preventing unauthorized or malicious routing updates.
Term 36
OSPF Default Route Advertisement is the process by which a router using the OSPF routing protocol tells other routers to send all traffic for unknown destinations to it, acting as a gateway of last resort.
Term 37
OSPF route summarization is a technique that combines multiple smaller network routes into a single, larger route advertisement to reduce the size of routing tables and improve network stability.
Term 38
OSPF special area types are configurations within an OSPF network that limit the type of routing information shared across an area to reduce routing table size and processing overhead.
Term 39
OSPF Virtual Link is a feature that connects two separate areas through a transit area, allowing an area to be linked to the backbone area without a direct physical connection.
Term 40
Policy Based Routing (PBR) is a technology that allows network traffic to be forwarded based on user-defined policies rather than just the destination IP address in the routing table.
Term 41
Route redistribution between protocols is the process of taking routes learned from one routing protocol and injecting them into another routing protocol so that networks using different protocols can communicate.
Term 42
The process of identifying and fixing problems in a permanent encrypted tunnel that connects two separate office networks over the internet.
Term 43
SNMPv3 configuration is the process of setting up the third version of the Simple Network Management Protocol on network devices to securely monitor and manage them using authentication and encryption.
Term 44
Syslog logging levels are numbered severity codes from 0 to 7 that classify system messages from emergencies (0) to debugging information (7).
Term 45
Unicast Reverse Path Forwarding is a network security feature that verifies the source address of incoming packets to prevent IP spoofing attacks.
