Question

Which of the following should a company use to reduce the latency of application that are deployed on a virtual private cloud?

Options

AVirtual load balancer
BNetwork address translation
CDirect connect
DMulti-availability zones

Explanation

A virtual load balancer is used to distribute application traffic across multiple instances, which can reduce latency by directing requests to the most responsive or least loaded servers.

Common mistakes.

B. Network address translation (NAT) primarily translates IP addresses for connectivity purposes and does not inherently reduce application latency. C: Direct Connect provides a dedicated connection between on-premises and cloud environments, reducing latency for hybrid setups, but it doesn't directly reduce latency between applications already deployed within a VPC. D: Deploying applications across multi-availability zones primarily enhances fault tolerance and high availability, but typically introduces increased latency between components due to geographical separation, rather than reducing it.
