AZ104 review mode set 4 question 52 incorrect answer or explanation

[jshurak]

Scenario 2’s answer or explanation is incorrect. The initial instance count is 3 and the minimum instance count is 2. Since the scale down value will bring the instance count below the minimum it would not occur. The correct answer should be 3 not 2.

Hello, I’ve just gotten back to that question. Here is the issue. In the first picture you can see that the initial instance count is 3. In scenario 2, the high workload is not enough to trigger a scale out. The workload then drops down to below the scale in threshold. While the minimum instance count is 2, the current instance count is 3 as nothing has occurred to change that.

The second screenshot shows the explanation of the answer. It is correct in its explanation except it is incorrect on the current number of vms running. It explains that the initial instance count is 2….that is incorrect, it is 3 as per the question description.

Hello jshurak,

Good day!

Thank you once again for posting here.

To clarify, the “minimum instance count of 2” mentioned in the explanation refers to the “Minimum number of VMs: 2” specified in the scenario and NOT the “Initial instance count: 3” (as seen in the provided images).

Here’s a detailed breakdown of the scenario:

Scenario 2: Initial state: 3 VMs First condition: 70% CPU for 8 minutes (no action taken as duration is less than 10 minutes) Second condition: 15% CPU for 12 minutes Scale In Policy: If CPU < 20%, decrease by 2 VMs

In this scenario, the scale-in condition is met (CPU < 20% for more than 10 minutes). Therefore, 2 VMs will be removed from the initial 3 VMs. However, the minimum number of VMs is set to 2, so the scale set cannot go below this number.

Result: 3 (initial) – 1 (scaled in, limited by minimum) = 2 VMs

I hope this clears up any confusion. We appreciate your feedback, as it helps us improve our content and explanations.
