Question 28 (Topic 1)

A company runs an application across multiple AWS Regions and multiple Availability Zones. The company needs to expand to a new AWS Region. Low latency is critical to the functionality of the application. A network engineer needs to gather metrics for the latency between the existing. Regions and the new Region. The network engineer must gather metrics for at least the previous 30 days. Which solution will meet these requirements?

Select an option, then click Submit answer.

  • ○ Configure an AWS Network Access Analyzer Network Access Scope, and use the analysis to review the latency.
  • ○ Set up AWS Network Manager Infrastructure Performance. Publish network performance metrics to Amazon CloudWatch.
  • ○ Use an Amazon VPC Reachability Analyzer path to review the latency.
  • ○ Set up VPC Flow Logs. Publish log metrics to Amazon CloudWatch.
Question 29 (Topic 1)

A company has multiple firewalls and ISPs for its on-premises data center. The company has a single AWS Site-to-Site VPN connection from the company's on-premises data center to a transit gateway. A single ISP services the Site-to-Site VPN connection. Multiple VPCs are attached to the transit gateway. A customer gateway that the Site-to-Site VPN connection uses fails. Connectivity is completely lost, but the company's network team does not receive a notification. The network team needs to implement redundancy within a week in case a single customer gateway fails again. The team wants to use an Amazon CloudWatch alarm to send notifications to an Amazon Simple Notification Service (Amazon SNS) topic if any tunnel of the Site-to-Site VPN connection fails. Which solution will meet these requirements MOST cost-effectively?

Select an option, then click Submit answer.

  • ○ Replace the existing customer gateway with a new router. Create a new Site-to-Site VPN connection to the transit gateway. For each VPN connection, set up a CloudWatch TunnelState alarm for the VPN connection. Use a value of 0 for the alarm.
  • ○ Use a second customer gateway and a second ISP. Create a new Site-to-Site VPN connection to the transit gateway. For each VPN connection, set up a CloudWatch TunnelState alarm for the VPN connection. Use a value of less than 1 for the alarm.
  • ○ Add an AWS Direct Connect connection to the existing Site-to-Site VPN connection to the transit gateway. For each VPN connection, set up a CloudWatch TunnelState alarm for the VPN connection. Use a value of failed for the alarm.
  • ○ Use a second customer gateway with the existing ISP. Create a new Site-to-Site VPN connection to the transit gateway. For each VPN connection, set up a CloudWatch TunnelState alarm for the VPN connection. Use a value of unavailable for the alarm.
Question 30 (Topic 1)

A company is using AWS Fargate to deploy many containerized web applications to a VPC. The applications must all be reachable through various DNS names on the standard port for HTTPS traffic. The company uses an Application Load Balancer (ALB) to handle traffic to each of the applications. The company uses the AWS Cloud Development Kit (AWS CDK) to automate the deployment process. The company uses two types of CDK stacks. The company uses one common stack to build the VPC itself and other shared infrastructure. The company also uses a set of application-specific stacks that contain details and logic for each application. The company needs to correctly allocate ALB-related resources between the two types of stacks. Which combination of solutions will provide a repeatable allocation of resources to the common stack and application-specific stacks? (Choose three.)

Select an option, then click Submit answer.

  • ○ ALB listener in the common stack
  • ○ ALB listener in the application-specific stacks
  • ○ ALB listener host header rule in the common stack
  • ○ ALB listener host header rule in the application-specific stacks
  • ○ ALB target group in the common stack
  • ○ ALB target group in the application-specific stacks
