A company runs a TCP-based application that requires extreme performance and low latency. The application is deployed on EC2 instances in a VPC. The company wants to use a load balancer that provides the lowest possible latency and can handle millions of requests per second. What should the company use?

An Application Load Balancer (ALB)

Amazon Route 53 with weighted routing

A company wants to monitor network traffic in its VPC to identify potential security threats and optimize costs. The company wants a solution that is cost-effective and provides detailed information about network traffic. What should the company do?

Use Amazon GuardDuty to monitor network traffic.

Enable VPC Flow Logs and publish them to Amazon S3.

Enable AWS CloudTrail to capture network traffic.

Use AWS Trusted Advisor to monitor network traffic.

Which statement correctly compares AWS Site-to-Site VPN and AWS Direct Connect in terms of cost?

Site-to-Site VPN has no data transfer costs.

Site-to-Site VPN provides more consistent and lower latency than Direct Connect.

Direct Connect typically has higher upfront and recurring costs than Site-to-Site VPN.

Direct Connect is always more cost-effective for small data volumes.

Which statement accurately compares NAT gateways and NAT instances for outbound internet access?

NAT gateways are a managed service that can provide higher availability with less administrative effort than NAT instances.

NAT gateways do not incur data processing charges.

NAT instances are always more cost-effective than NAT gateways for any workload.

NAT instances automatically scale to handle traffic spikes.
