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

AYes

BNo

Show Suggested 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.

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.

Absolutely, node affinities are the way to go here. Keeps those dev and prod containers nice and separate, just like the security policy ordered!
