Alerts and action groups in Azure - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to create an alert rule that triggers when CPU usage exceeds 80%.

Azure

az monitor metrics alert create --name HighCPUAlert --resource-group MyResourceGroup --scopes MyVMResourceId --condition "avg Percentage CPU > [1]" --window-size 5m --evaluation-frequency 1m

Drag options to blanks, or click blank then click option'

A70

B100

C90

D80

💡 Hint

Common Mistakes

Using a threshold lower than 80 causes too many alerts.

Using a threshold higher than 80 might miss important alerts.

The alert triggers when the average CPU usage is greater than 80%, so the correct threshold is 80.

Complete the code to add an action group that sends an email when the alert fires.

Azure

az monitor action-group create --name MyActionGroup --resource-group MyResourceGroup --short-name MyActionGroup [1] EmailReceiver [e-mail]

Drag options to blanks, or click blank then click option'

A--email-receiver

B--email

C--email-address

D--receiver-email

Attempts:

💡 Hint

Common Mistakes

Using incorrect parameter names like '--email' or '--email-address'.

Missing the required parameter for email receiver.

The correct parameter to specify an email receiver in Azure CLI is --email-receiver.

Fix the error in the alert condition syntax to correctly monitor disk space below 10%.

Azure

az monitor metrics alert create --name LowDiskSpace --resource-group MyResourceGroup --scopes MyDiskResourceId --condition "avg [1] < 10" --window-size 5m --evaluation-frequency 1m

Drag options to blanks, or click blank then click option'

ADisk Space

BLogicalDisk\% Free Space

CLogicalDisk Free Space

DFree Disk Space

💡 Hint

Common Mistakes

Using metric names without escaping special characters.

Using incomplete or incorrect metric names.

The correct metric name for monitoring free disk space percentage is LogicalDisk\% Free Space with the backslash escaping the percent sign.

4fill in blank

hard

Fill both blanks to create an alert rule that triggers when memory usage is above 75% and sends an SMS notification.

Azure

az monitor metrics alert create --name HighMemoryAlert --resource-group MyResourceGroup --scopes MyVMResourceId --condition "avg [1] > 75" --window-size 5m --evaluation-frequency 1m --action-group [2]

Drag options to blanks, or click blank then click option'

APercentage Memory Used

BMyEmailActionGroup

CMySMSActionGroup

DMemory Usage

Attempts:

3 left

💡 Hint

Common Mistakes

Using incorrect metric names like 'Memory Usage'.

Using the wrong action group for SMS notifications.

The metric to monitor memory usage is Percentage Memory Used. The action group to send SMS notifications is MySMSActionGroup.

5fill in blank

hard

Fill all three blanks to create an action group with email, SMS, and webhook receivers.

Azure

az monitor action-group create --name MultiChannelGroup --resource-group MyResourceGroup --short-name MultiChannelGroup [1] EmailReceiver [e-mail] [2] SMSReceiver [phone] [3] WebhookReceiver https://example.com/alert

Drag options to blanks, or click blank then click option'

A--email-receiver

B--sms-receiver

C--webhook-receiver

D--email

Attempts:

3 left

💡 Hint

Common Mistakes

Using incorrect parameter names like '--email' instead of '--email-receiver'.

Mixing up parameters between receiver types.

The correct parameters for action group receivers are --email-receiver, --sms-receiver, and --webhook-receiver.

Practice

1. What is the main purpose of an alert in Azure Monitor?

easy

A. To create virtual machines automatically

B. To notify you when a specific condition occurs in your cloud resources

C. To store data backups securely

D. To manage user permissions in Azure

Solution

1. Step 1: Understand what alerts monitor

   Alerts watch cloud resources and trigger when certain conditions happen, like high CPU or errors.

2. Step 2: Identify alert purpose

   The main goal is to notify you so you can act quickly and keep systems healthy.

3. Final Answer:

   To notify you when a specific condition occurs in your cloud resources -> Option B

4. Quick Check:

   Alerts = Notifications on conditions [OK]

Hint: Alerts notify on issues; think 'watch and warn' [OK]

Common Mistakes:

• Confusing alerts with resource creation
• Thinking alerts manage backups
• Assuming alerts control user access

2. Which of the following is the correct way to associate an action group with an alert rule in Azure?

easy

A. Create a new virtual network with the action group name

B. Add the action group as a tag to the resource

C. Specify the action group ID in the alert rule's actions section

D. Assign the action group to the resource's access control list

Solution

1. Step 1: Review alert rule configuration

   Alert rules include an actions section where you specify which action groups to notify or trigger.

2. Step 2: Confirm correct association method

   You link an action group by referencing its ID in the alert rule's actions, not by tags or network settings.

3. Final Answer:

   Specify the action group ID in the alert rule's actions section -> Option C

4. Quick Check:

   Action group linked via alert actions [OK]

Hint: Action groups go in alert actions, not tags or ACLs [OK]

Common Mistakes:

• Trying to add action groups as resource tags
• Confusing network setup with alert actions
• Assigning action groups to access control lists

3. Given this alert rule JSON snippet, what action group will be triggered when the alert fires?

{
  "name": "HighCPUAlert",
  "criteria": {"metricName": "Percentage CPU", "threshold": 80},
  "actions": [{"actionGroupId": "/subscriptions/123/resourceGroups/rg1/providers/microsoft.insights/actionGroups/NotifyTeam"}]
}

medium

A. NotifyTeam

B. BackupGroup

C. ScaleUpGroup

D. SecurityAlertGroup

Solution

1. Step 1: Locate action group ID in alert JSON

   The actions array contains an actionGroupId ending with 'NotifyTeam'.

2. Step 2: Match action group name

   The ID clearly points to the 'NotifyTeam' action group, so this group triggers on alert.

3. Final Answer:

   NotifyTeam -> Option A

4. Quick Check:

   ActionGroupId ends with NotifyTeam [OK]

Hint: Look for actionGroupId value in alert JSON [OK]

Common Mistakes:

• Picking wrong action group from unrelated names
• Ignoring the actionGroupId field
• Assuming default action group triggers

4. You created an alert rule but no notifications are sent when the condition is met. What is the most likely cause?

medium

A. The alert rule does not have any action groups assigned

B. The resource is offline

C. The alert rule threshold is set too low

D. The action group is disabled in Azure Security Center

Solution

1. Step 1: Check alert rule configuration

   If no notifications are sent, first verify if the alert rule has action groups assigned to send alerts.

2. Step 2: Understand action group role

   Action groups define who and how notifications are sent; without them, alerts trigger but no actions occur.

3. Final Answer:

   The alert rule does not have any action groups assigned -> Option A

4. Quick Check:

   No action groups = no notifications [OK]

Hint: Alerts need action groups to send notifications [OK]

Common Mistakes:

• Assuming resource offline stops alerts
• Thinking threshold affects notification sending
• Confusing action group status with Security Center

5. You want to create an alert that sends an email and triggers an Azure Function when CPU usage exceeds 90%. Which setup correctly achieves this?

hard

A. Create an alert rule with a metric condition for CPU > 90%, and assign an action group with only Azure Function action

B. Create an alert rule with a log query for CPU > 90%, and assign an action group with only email action

C. Create an alert rule with a metric condition for CPU > 90%, but no action group is needed if you have an Azure Function

D. Create an alert rule with a metric condition for CPU > 90%, and assign an action group with email and Azure Function actions

Solution

1. Step 1: Define alert condition and actions

   The alert must watch CPU metric > 90%, so use a metric condition. To notify and trigger automation, use an action group with both email and Azure Function actions.

2. Step 2: Confirm action group capabilities

   Action groups can include multiple actions like email and Azure Functions, enabling combined notifications and automation.

3. Final Answer:

   Create an alert rule with a metric condition for CPU > 90%, and assign an action group with email and Azure Function actions -> Option D

4. Quick Check:

   Metric alert + action group with email & function [OK]

Hint: Use action group with all needed actions for alert [OK]

Common Mistakes:

• Omitting action group when automation is needed
• Using log query instead of metric for CPU
• Assigning incomplete actions in action group
