Question
When planning a new wired network for a customer, you need to create an NAE script that could enable a backup interface if all interfaces in an area are down. Which statement correctly describes the script needed?
A. You should have a class Agent(NAE), that defines a Rule to monitor the interfaces in the area, and with one or more Actions that define the condition that triggers an action to be done.
B. You should have a class Agent(NAE), that defines a Monitor to monitor the interfaces in the area, and with one or more Actions that define the condition that triggers an action to be done.
C. You should have a class Agent(NAE), that defines a Monitor to monitor the interfaces in the area, and with one or more Rules that define the condition that triggers an action to be done.
D. You should have a class Policy(NAE), that defines a Rule to monitor the interfaces in the area, and with one or more Actions that define the condition that triggers an action to be done.
Answer
C. You should have a class Agent(NAE), that defines a Monitor to monitor the interfaces in the area, and with one or more Rules that define the condition that triggers an action to be done.
Explanation
When creating an NAE (Network Analytics Engine) script for enabling a backup interface if all interfaces in an area are down, it’s crucial to understand the structure and components of the script. Let’s break down the correct approach:
- Class Agent(NAE): The script should start with defining a class that inherits from NAE. This class serves as the main container for the network monitoring and action logic.
- Monitor: Within the Agent(NAE) class, you need to define a Monitor. The Monitor is responsible for continuously observing the status of the interfaces in the specified area. It collects data about the interfaces’ operational state.
- Rules: The script should include one or more Rules. These Rules define the conditions that, when met, will trigger specific actions. In this case, the Rule would check if all interfaces in the monitored area are down.
- Actions: Although not explicitly mentioned in the correct answer, Actions are implied. When the conditions defined in the Rules are met, the corresponding Actions will be executed. In this scenario, the Action would be to enable the backup interface.
The key difference between the correct answer (C) and the incorrect options is the proper combination of Monitor and Rules within the Agent(NAE) class. Option A incorrectly uses a Rule instead of a Monitor for interface observation. Option B mistakenly uses Actions instead of Rules for defining trigger conditions. Option D incorrectly uses a Policy(NAE) class instead of Agent(NAE) and misplaces the Rule and Action components.
By following the structure outlined in option C, you create a script that effectively monitors the network interfaces, evaluates their status using defined rules, and can trigger the necessary action to enable the backup interface when required. This approach ensures a robust and efficient network management solution, which is crucial for the HPE6-A69 certification and real-world network planning scenarios.
