• Checking route tables for correct traffic flow.
• Using traceroute and ping commands within AWS CLI or EC2 instances to test connectivity.

Automating routine management tasks with scripts or IaC tools reduces human error and improves response time. Handling bottlenecks—like bandwidth saturation—may involve adjusting instance types, implementing traffic shaping, or deploying additional resources dynamically.

Real-world scenario: Suppose an application experiences intermittent connectivity. You might analyze VPC Flow Logs, identify dropped packets due to misconfigured security groups, and rectify the rules to restore service promptly.

Security and Compliance (20-25%)

Security is a core focus. You should be proficient in configuring network security controls:

• Using security groups for instance-level security.
• Configuring Network Access Control Lists (NACLs) for subnet-level filtering.
• Deploying firewalls with AWS Firewall Manager or WAF to protect web applications.

Designing for compliance standards involves implementing data encryption, audit logging, and access controls aligned with HIPAA, PCI DSS, or other regulations. For example, enabling VPC Flow Logs and integrating with AWS CloudTrail ensures auditability and accountability.

Best practices also include segmented networks, least privilege access, and continuous security assessments. Using AWS Shield provides DDoS protection, while AWS Config rules monitor compliance posture automatically.

Automation and Optimization (10-15%)

Efficiency in deployment and management comes from automation. Infrastructure as Code (IaC) tools like CloudFormation or Terraform enable repeatable, version-controlled network setups.

Automating network updates minimizes manual errors and accelerates scaling. For instance, deploying a new VPC and associated resources via CloudFormation templates ensures consistency across environments.

Optimization strategies include cost analysis—using AWS Cost Explorer—and performance tuning, such as choosing optimal instance types or leveraging caching with CDN services like Amazon CloudFront.

Leverage AWS tools like Systems Manager for automation workflows, or AWS Lambda for event-driven network management tasks, to create a responsive, scalable infrastructure.
