ANS-C01 Exam
A company runs a workload in a single VPC on AWS. The company’s architecture contains several interface VPC endpoints for AWS services, including Amazon CloudWatch Logs and AWS Key Management Service (AWS KMS). The endpoints are configured to use a shared security group. The security group is not used for any other workloads or resources.
After a security review of the environment, the company determined that the shared security group is more permissive than necessary. The company wants to make the rules associated with the security group more restrictive. The changes to the security group rules must not prevent the resources in the VPC from using AWS services through interface VPC endpoints. The changes must prevent unnecessary access.
The security group currently uses the following rules:
• Inbound - Rule 1
Protocol: TCP
Port: 443
Source: 0.0.0.0/0
• Inbound - Rule 2
Protocol: TCP
Port: 443
Source: VPC CIDR
• Outbound - Rule 1
Protocol: All
Port: All
Destination: 0.0.0.0/0
Which rule or rules should the company remove to meet with these requirements?
A company has deployed a web application on AWS. The web application uses an Application Load Balancer (ALB) across multiple Availability Zones. The targets of the ALB are AWS Lambda functions. The web application also uses Amazon CloudWatch metrics for monitoring.
Users report that parts of the web application are not loading properly. A network engineer needs to troubleshoot the problem. The network engineer enables access logging for the ALB.
What should the network engineer do next to determine which errors the ALB is receiving?
A company is deploying third-party firewall appliances for traffic inspection and NAT capabilities in its VPC. The VPC is configured with private subnets and public subnets. The company needs to deploy the firewall appliances behind a load balancer.
Which architecture will meet these requirements MOST cost-effectively?
