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 distributes incoming application traffic across multiple backend servers, preventing any single server from becoming a bottleneck and thereby reducing application latency.

Common mistakes.

B. Network address translation (NAT) modifies IP address information in packet headers and is primarily for IP address conservation or security, not for reducing application latency.
C. Direct Connect establishes a dedicated network connection from on-premises to a cloud provider, reducing latency between on-premises and cloud resources, but not necessarily for applications within the virtual private cloud itself.
D. Multi-availability zones improve fault tolerance and high availability by distributing resources geographically, but it doesn't inherently reduce latency for a single application request unless combined with other strategies like regional load balancing.
