8. Disaster Recovery & Business Continuity:

Architect disaster recovery (DR) solutions, ensuring the replication of network infrastructure across geographic locations for failover.

Design and test failover mechanisms, such as multi-site DR, backup WAN paths, and redundant data center connectivity.

Implement and test automated failover and recovery processes to ensure minimal downtime in case of network failures.

9. Automation & Orchestration:

Implement network automation strategies using tools such as Ansible, Python, Terraform, and Cisco DNA to automate routine tasks and configuration management.

Create automated scripts for provisioning, configuring, and monitoring network devices and services to reduce manual effort and errors.

Develop and deploy automated infrastructure for network monitoring and alerting systems to ensure real-time awareness of network health.
