Determining QoS for IP Services

C.

IP SLA allows an IT professional to collect information about network performance in real time.

Therefore it helps determine whether the QoS on the network is sufficient for IP services or not.

Cisco IOS Embedded Event Manager (EEM) is a powerful and flexible subsystem that provides real-time network event detection and onboard automation.

It gives you the ability to adapt the behavior of your network devices to align with your business needs.

The feature or protocol that determines whether the QoS on the network is sufficient to support IP services is IP SLA (Internet Protocol Service Level Agreement).

IP SLA is a Cisco protocol that measures the performance of IP services by simulating network traffic or by generating a test traffic on a network. IP SLA monitors various network performance metrics such as delay, packet loss, and jitter.

By monitoring these performance metrics, IP SLA can determine whether the QoS on the network is sufficient to support IP services. If the QoS is not sufficient, IP SLA can trigger an alert to notify the network administrator or take automatic actions to adjust the network configuration to improve QoS.

LLDP (Link Layer Discovery Protocol) and CDP ( Cisco Discovery Protocol) are network protocols used for device discovery and management. They do not provide any QoS monitoring or measurement capabilities.

EEM (Embedded Event Manager) is a software component used for automating network management tasks. EEM can be used to configure QoS policies or to trigger QoS-related actions based on network events, but it does not provide any QoS monitoring or measurement capabilities on its own.
