Alibaba ACA-CloudNative Exam - Topic 5 Question 60 Discussion

Actual exam question for Alibaba's ACA-CloudNative exam

Question #: 60
Topic #: 5

For worker nodes, which of the following statements are correct? (Number of correct answers: 3)

Score 2

AIf worker node capacity is more than 1000 cores, consider using EBM (ECS Bare Metal).

BYou should choose higher instance specifications, because you can run more tasks on a single
worker node this way, improving utilization.

CYou should choose the lowest possible instance specification for your workers, to reduce costs.

DEnsure redundant worker node capacity for each running pod.

EAttach data disk to worker nodes, because Docker image, system logs, and temp data will
consume space. Without a data disk, systems can quickly run out of disk space.

Wait, are we sure about A? Seems a bit extreme for just over 1000 cores.

E makes sense, running out of disk space is a real headache.

Totally disagree with C, low specs can lead to performance issues.

A is spot on, definitely consider EBM for high core counts.

D seems important for reliability, but I can't recall if it's always required for every pod. I should double-check that.

I feel like C might be a trap answer. Lower specs could save costs, but it might not be efficient for workloads.

I remember practicing a question about instance specifications, and I think B is correct because higher specs can really help with task management.

I think option A sounds familiar, but I'm not entirely sure if EBM is always necessary for high core counts.

This seems straightforward to me. I just need to analyze the GTID details and match them up with the answer choices. I'm confident I can figure this out.

I've got this! The agent serves as a Policy Enforcement Point (PEP), which means it enforces the policies defined by the Policy Definition Point (PDP). Option B is the correct answer.

Hmm, I'm not entirely sure about this. I'll need to review the TOGAF ADM steps and see where the Architecture Vision document fits in.
