Exam AZ-204 topic 16 question 1 discussion

C is the correct answer. We are dealing with containers here not VM so "CPU usage" is a valid condition. Had it been VM then it should have been "Percentage CPU usage". 800 is also correct since for containers its measured in millicores. Ref : https://docs.microsoft.com/en-us/azure/azure-monitor/platform/metrics-supported#microsoftcontainerinstancecontainergroups

Shouldn't it be > 80 (instead of 800)?

In 2025 the questions are half answered, many parts are missing so it is difficult to answer

B - Scenario: An alert must be raised if the ContentUploadService uses more than 80 percent of available CPU-cores Azure Monitor provides the following metrics for Azure Container Instances. These metrics are available for a container group and individual containers. By default, the metrics are aggregated as averages. CPU Usage - measured in millicores. One millicore is 1/1000th of a CPU core, so 500 millicores represents usage of 0.5 CPU core. Memory Usage - in bytes. Network Bytes Received Per Second and Network Bytes Transmitted Per Second. https://docs.microsoft.com/en-us/azure/container-instances/container-instances-monitor

C is the correct answer.

Did my exam on 15th November 2022. This test case was on it, but not this specific question.

All wrong. 1. It needs to be avg CPU, it doen't make sense for sudden spike of any individual computation, but if Average is over, it needs the alert. 2. I don't see the syntax "CPU Usage" and the words do not match the percentage. 3. Percentage > 80, not 8 nor 800, see from the official example. az monitor metrics alert create -n alert1 -g {ResourceGroup} --scopes {VirtualMachineID1} {VirtualMachineID2} {VirtualMachineID3} \ --condition "avg Percentage CPU > 90" --description "High CPU" --region westus

C is correct answer.

We want an alert for an exceeded limit. A,B are invalid from the start, we do not care about averages. D has a wrong number in the evaluation expression C is the correct answer - that "800" is units per thousand. 800/1000 is 80%

ContentUploadService is in ACI. when reading Microsft document found that CPU Usage is used for ACI and Avg percentage is used for VM Also we don't want average just 80% of available CPU SO ANSWER IS C

According to https://docs.azure.cn/zh-cn/cli/monitor/metrics/alert?view=azure-cli-latest The answer is B. However, B states 800, I don't know if it's a typo

similar alerts on https://docs.microsoft.com/en-us/cli/azure/monitor/metrics/alert?view=azure-cli-latest#az-monitor-metrics-alert-create

Unit avg CPU: per hundred (%) Unit CPU: per thousand A:8% B:800% C:80% D:0.8%

It is a ACI not a VM so "CPU usage" is correct

I believe its C based on this Ref: https://docs.microsoft.com/en-us/azure/container-instances/container-instances-monitor

It's not A or B because we don't care about average usage, we want an alert when the usage goes above 80%. Therefore it mus be C, because as others have stated, CPU usage measurement is in millicores, so 800 would be 80%. Correct answer: C

"The ContentAnalysisService is deployed with Azure Container Instances" "The solution will use eight CPU cores." CPU usage is measured in millicore (https://docs.microsoft.com/en-us/azure/container-instances/container-instances-monitor) so correct answer should be 'C' (80% = 800millicore)
