What is a key aspect of ongoing support for automated networks?

Regularly updating automation scripts and models to adapt to changes

Avoiding any changes to the network after initial deployment

Disabling automation features to simplify troubleshooting

Removing all manual monitoring processes

What is a key characteristic of a controller-based network architecture?

All devices must be from the same vendor

Distributed control plane on every device

Centralized control plane with a logically centralized controller

Why is monitoring important in an automated network environment?

To detect failures and verify that automation is working as expected

To replace the need for automation

To increase the complexity of network operations

To manually configure devices instead of using APIs

A network operations team is supporting a model-driven automation solution. They have noticed that some automation scripts fail intermittently due to timeouts when connecting to devices. What is the most effective way to troubleshoot and improve the reliability of these scripts?

Run the scripts only during off-peak hours when the network is less busy.

Disable the scripts and perform all configuration changes manually to avoid failures.

Add retry logic with exponential backoff to the scripts and monitor device response times to identify patterns.

Increase the timeout values in the scripts to a very high number to ensure they never time out.

When designing an automation workflow, what is a key consideration for integration with existing network infrastructure?

Disabling all manual configuration methods

Using a single vendor for all network equipment

Ensuring compatibility with existing device APIs and protocols

Replacing all legacy devices with modern ones
