Docker DCA Exam - Topic 5 Question 107 Discussion

Actual exam question for Docker's DCA exam
Question #: 107
Topic #: 5
[All DCA Questions]

A company's security policy specifies that development and production containers must run on separate nodes in a given Swarm cluster.

Can this be used to schedule containers to meet the security policy requirements?

Solution: node affinities

Show Suggested Answer Hide Answer
Suggested Answer: A

They provide granular control over where pods (or in this case, containers) are scheduled, based on the labels of the nodes1. In the context of Docker Swarm, this means that you could use node affinities to ensure that development and production containers are scheduled on separate nodes, thus meeting the company's security policy requirements12345.

I'm a bit confused. Can node affinities really guarantee that development and production containers won't end up on the same node?

I think node affinities can help with that, but I'm not entirely sure how they enforce separation in Swarm.

I'm a bit confused by the wording of the question. What exactly do they mean by "can this be used"? Is the solution just to use node affinities, or is there more to it? I'll need to carefully read through the details again.

Okay, let's think this through step-by-step. The security policy says development and production containers must run on separate nodes. If we use node affinities, we can specify which types of containers should be scheduled on which nodes. I think the answer is yes, we can use this to meet the policy requirements.

Node affinities, huh? Sounds like a fancy dance move, but I guess it'll do the trick. As long as it keeps the suits happy, I'm on board.
