Docker DCA Exam - Topic 1 Question 93 Discussion

Actual exam question for Docker's DCA exam
Question #: 93
Topic #: 1
[All DCA Questions]

Will this action upgrade Docker Engine CE to Docker Engine EE?

Solution. Disable the Docker service via 'chkconfig' or 'systemctl'.

Show Suggested Answer Hide Answer
Suggested Answer: B

Docker Swarm requires more than one manager node to achieve fault tolerance12. A single manager node is not fault tolerant because if it goes down, the entire cluster goes down3. For a swarm to be fault-tolerant, it needs to have an odd number of manager nodes2. For example, a three-manager swarm tolerates a maximum loss of one manager2. Therefore, a configuration with one manager node for two worker nodes will not achieve fault tolerance for managers in a swarm12.

I'm leaning towards "No" because I don't recall any upgrade process that only involves disabling the service.

I feel like I've seen something similar where just stopping a service doesn't change the version.

I remember a practice question about Docker versions, and I think it mentioned that you need to install EE separately.

I think disabling the Docker service is just a step in the process, but I'm not sure if it actually upgrades to EE.

Disabling the service, got it. I'll make sure to do that carefully and then check the version again to confirm it didn't upgrade. Gotta be thorough on these exam questions.

Wait, so the solution is just to disable the service? That seems a bit too simple. I want to make sure I fully understand what's going on here before I answer.

Okay, I think I've got this. Disabling the service first is a smart move to avoid any unwanted upgrades. Let me double-check the details on that.

Disabling the Docker service - that's an interesting approach. I wonder if there's any other way to check the current version before making any changes.

Hmm, this seems like a tricky one. I'll need to think through the steps carefully to make sure I don't accidentally upgrade to the Enterprise Edition.

I'm not entirely sure, but I remember that the local IP should have something specific in the path. Was it `/putxml` or something like that?

Disabling Docker to upgrade? Sounds like a surefire way to end up in Docker Jail. I'll pass on that one, thanks.
