Topic 1 Question 92
A company's security guidelines state that all outbound traffic from a VPC to the company's on-premises data center must pass through a security appliance. The security appliance runs on an Amazon EC2 instance. A network engineer needs to improve the network performance between the on-premises data center and the security appliance.

Which actions should the network engineer take to meet these requirements?

2 つ選択
- Use an EC2 instance that supports enhanced networking.
- Send outbound traffic through a transit gateway.
- Increase the EC2 instance size.
- Place the EC2 instance in a placement group within the VPC.
- Attach multiple elastic network interfaces to the EC2 instance.

  Needs to improve the network performance between the on-premises data center and the security appliance.
  
  Placement Groups is to allow better throughput between EC2 instances in your VPC. This does not improve throughput between the SINGULAR EC2 security appliance (security appliance runs on an Amazon EC2 instance) and on-prem DC. Therefore, increasing instance size (more vCPU/RAM) is the correct answer.
  
  Ref: Look at Table 1 and 2, last page of this document https://www.paloaltonetworks.com/apps/pan/public/downloadResource?pagePath=/content/pan/en_US/resources/datasheets/vm-series-spec-sheet
  
  All the best.

- Should be AC. There is only one EC2 instance involved in this scenario so placement groups is not a good option.
