Cisco 350-901 Exam - Topic 1 Question 55 Discussion

Refer to the exhibit.A developer runs the docker service scale command to increase the number of replicas for the cisco_devnet service. The swarm cluster is using a private IP address subnet. The service has these design requirements:It must be hosted behind a virtual IP address that is reachable from the Internet.For security reasons, the Docker swarm cluster subnet must not be reachable from the Internet.Which design approach is used to fulfill the requirements?
A) Create an overlay network by using a globally roulable subnet and enable a routing mesh within the swarm cluster.
B) Create a bridge network by using a globally routable subnet and enable a routing mesh within the swarm cluster.
C) Configure an external load balancer to route requests to the swarm service by using VPN.
D) Configure an external load balancer to route requests to the swarm service by using NAT.

Wait, why would we use a globally routable subnet? Sounds risky!

NAT is a classic solution, can't go wrong with that!

I vaguely remember that using a bridge network might expose the swarm to the Internet, which doesn't seem secure. So, I'm leaning away from option B.

I feel like the routing mesh concept was mentioned in relation to overlay networks, but I can't recall if that applies to this scenario.

I think we practiced a similar question where we had to decide between NAT and VPN for load balancing. I might lean towards option D, but I'm not completely confident.

I remember we discussed overlay networks in class, but I'm not sure if they are the right choice here since the subnet needs to be private.

Okay, let's see here. The school wants to use Salesforce and the EDA, and create Giving Pages. I'll need to think about what that might require in terms of compatibility.

Okay, I've got this. The directions are asking how to work with a specific tool, and the options are describing different tool-related tasks. I just need to identify which option matches the directions.

Okay, let me see. I know that white box testing involves looking at the internal structure and code of the software, while black box testing focuses on the external functionality without considering the internal implementation. I think option D is the best answer here.
