• Question 983:

  A company wants to minimize network latency between its Amazon EC2 instances. The EC2 instances do not need to be highly available.

  Which solution meets these requirements?

  A. Use EC2 instances in a single Availability Zone.
  B. Use Amazon CloudFront as the database for the EC2 instances.
  C. Use EC2 instances in the same edge location and the same Availability Zone.
  D. Use EC2 instances in the same edge location and the same AWS Region.
  A. Use EC2 instances in a single Availability Zone.

  ---

  Explanation

  Using EC2 instances in a single Availability Zone is a solution that meets the requirements of minimizing network latency between the EC2 instances and not needing high availability. An Availability Zone is a physically isolated location within an AWS Region that has its own power, cooling, and network connectivity. EC2 instances within the same Availability Zone can communicate with each other using low-latency private IP addresses. However, EC2 instances in a single Availability Zone are not highly available, because they are vulnerable to failures or disruptions that affect the Availability Zone

  Explanation

  AWS Fargate and Amazon S3 are both serverless services. Fargate allows users to run containers without managing the underlying infrastructure, while S3 provides object storage without the need for provisioning or managing servers. Amazon EC2, Amazon Managed Streaming for Apache Kafka, and Amazon EMR involve server management to varying degrees and are not serverless by nature.

• Question 988:

  Which AWS service or feature is associated with a subnet in a VPC and is used to control inbound and outbound traffic?

  A. Amazon Inspector
  B. Network ACLs
  C. AWS Shield
  D. VPC Flow Logs
  B. Network ACLs

  ---

  Explanation

  Network ACLs (network access control lists) are an optional layer of security for your VPC that act as a firewall for controlling traffic in and out of one or more subnets. You can use network ACLs to allow or deny traffic based on protocol, port, or source and destination IP address. Network ACLs are stateless, meaning that they do not track the traffic that flows through them. Therefore, you must create rules for both inbound and outbound traffic.
