  • ○ The port forwarding settings do not allow access to internal services from the internet.
Question 5 (Topic 1)

A company has migrated its application to AWS. The company will host the application on Amazon EC2 instances of multiple instance families. During initial testing, a SysOps administrator identifies performance issues on selected EC2 instances. The company has a strict budget allocation policy, so the SysOps administrator must use the right resource types with the performance characteristics to match the workload. What should the SysOps administrator do to meet this requirement?

Select an option, then click Submit answer.

  • ○ Purchase regional Reserved Instances (RIs) for immediate cost savings. Review and take action on the EC2 rightsizing recommendations in Cost Explorer. Exchange the RIs for the optimal instance family after rightsizing.
  • ○ Purchase zonal Reserved Instances (RIs) for the existing instances. Monitor the RI utilization in the AWS Billing and Cost Management console. Make adjustments to instance sizes to optimize utilization.
  • ○ Review and take action on AWS Compute Optimizer recommendations. Purchase Compute Savings Plans to reduce the cost that is required to run the compute resources.
  • ○ Review resource utilization metrics in the AWS Cost and Usage Report. Rightsize the EC2 instances. Create On-Demand Capacity Reservations for the rightsized resources.
Question 6 (Topic 1)

A SysOps administrator is responsible for managing a fleet of Amazon EC2 instances. These EC2 instances upload build artifacts to a third-party service. The third-party service recently implemented a strict IP allow list that requires all build uploads to come from a single IP address. What change should the systems administrator make to the existing build fleet to comply with this new requirement?

Select an option, then click Submit answer.

  • ○ Move all of the EC2 instances behind a NAT gateway and provide the gateway IP address to the service.
  • ○ Move all of the EC2 instances behind an internet gateway and provide the gateway IP address to the service.
  • ○ Move all of the EC2 instances into a single Availability Zone and provide the Availability Zone IP address to the service.
  • ○ Move all of the EC2 instances to a peered VPC and provide the VPC IP address to the service.
