An organization's web server farm, which is hosted in the cloud with DNS load balancing, is experiencing a spike in network traffic.
This has caused an outage of the organization's web server infrastructure.
Which of the following should be implemented to prevent this in the future as a mitigation method?

A. B. C. D.D.
Out of the given options, the most appropriate mitigation method for preventing network traffic spikes that cause web server infrastructure outage is deploying a vADC appliance (option D).
A vADC (Virtual Application Delivery Controller) appliance is a software-based load balancer that distributes network traffic evenly across multiple web servers. It can also handle network traffic spikes by automatically scaling up or down based on the demand. In addition, a vADC appliance can also provide other services such as SSL offloading, content caching, and application firewall.
DLP (Data Loss Prevention) is a security technology that focuses on preventing unauthorized data access or data leakage. DLP is not directly related to mitigating network traffic spikes and web server infrastructure outage.
Microsegmentation is a security technique that divides a network into smaller segments to reduce the attack surface and limit the potential impact of a security breach. While microsegmentation can help secure the web server farm, it does not address the issue of network traffic spikes.
DNSSE (DNS Security Extensions) is a security protocol that adds digital signatures to DNS (Domain Name System) data to ensure its authenticity and integrity. While DNSSE can help secure the DNS infrastructure, it does not address the issue of network traffic spikes.
Therefore, deploying a vADC appliance is the best option to mitigate the issue of network traffic spikes that cause web server infrastructure outage in a cloud environment with DNS load balancing.
