Fortinet Exam NSE6_WCS-7.0 Topic 1 Question 4 Discussion

Actual exam question for Fortinet's NSE6_WCS-7.0 exam

Question #: 4
Topic #: 1

An AWS administrator is designing internet connectivity for an organization's virtual public cloud (VPC). The organization has web servers with private addresses that must be reachable from the internet. The web servers must be highly available.

Which two configurations can you use to ensure the web servers are highly available and reachable from the internet? (Choose two.)

ADeploy a network load balancer.

BConfigure a network address translation (NAT) Gateway in your VPC. Place web servers behind the NAT Gateway.

CAdd a route to the default virtual public cloud (VPC) route table forwarding all traffic to the internet gateway.

DDeploy web servers in multiple availability zones.

Show Suggested Answer

Suggested Answer: A, D

Network Load Balancer:

Deploying a network load balancer ensures that incoming traffic is distributed across multiple web servers, providing high availability and redundancy. This setup helps in managing traffic efficiently and maintaining service uptime even if some servers fail (Option A).

Multiple Availability Zones:

Deploying web servers in multiple availability zones (AZs) enhances fault tolerance and availability. If one AZ goes down, servers in other AZs can continue to handle the traffic, ensuring the web application remains accessible (Option D).

Other Options Analysis:

Option B is incorrect because NAT Gateways are used to provide internet access to instances in private subnets, not to make private addresses reachable from the internet.

Option C is not sufficient on its own for high availability. Adding a route to the default VPC route table forwarding traffic to the internet gateway makes the VPC internet-accessible but does not ensure high availability.

A network load balancer sounds like a solid choice to ensure high availability. And placing the web servers behind a NAT Gateway is a great way to keep them private yet accessible from the internet. I'm on board with options A and B.
