Network Infrastructure Monitoring and Reaction

A.

The feature that should be used to meet the design requirement of monitoring and reacting to certain conditions in the network for the new HR application is Cisco IOS Embedded Event Manager (EEM).

Cisco IOS Embedded Event Manager (EEM) is a feature available in Cisco devices that allows users to monitor and respond to specific events or conditions within the network infrastructure. It is a powerful tool that provides a scripting environment to automate tasks, monitor network events, and take actions based on certain conditions.

EEM works by allowing users to define a set of event detectors, which monitor specific conditions in the network, and a set of actions, which are taken when these conditions are met. These actions can be anything from logging a message to the console to sending an email notification or executing a script.

With EEM, it is possible to automate a variety of network management tasks, such as device configuration changes, fault detection and recovery, and proactive monitoring of network health. EEM can be configured to monitor any device event, such as interface status changes, CPU utilization, memory usage, or SNMP traps.

IP SLA, reflexive ACLs, route maps, SOAP, and exit status are not suitable for meeting the design requirement of monitoring and reacting to certain conditions in the network for the new HR application.

IP SLA (Internet Protocol Service Level Agreement) is a Cisco IOS feature that allows users to measure network performance by generating synthetic traffic and monitoring the response time. While useful for monitoring network performance, it is not designed for automating network management tasks.

Reflexive ACLs (Access Control Lists) are a type of firewall filter that dynamically allows return traffic through a firewall based on the initial outgoing traffic. They are useful for securing the network, but they do not provide the automation and event-driven functionality required for monitoring and reacting to network conditions.

Route maps are used in routing protocols to filter, modify, or redistribute routing information. They are not designed for network monitoring or automation.

SOAP (Simple Object Access Protocol) is a protocol used for exchanging structured data over the internet. While useful for web services, it is not designed for network automation or monitoring.

Exit status is a code returned by a command or script to indicate the success or failure of the operation. While useful for scripting, it is not designed for network automation or monitoring.

In conclusion, Cisco IOS Embedded Event Manager (EEM) is the most suitable feature for meeting the design requirement of monitoring and reacting to certain conditions in the network for the new HR application.
