ANS-C01 Network Design Practice Question

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

• ✓

  1. Create a CloudWatch Logs log group. 2. Create an IAM role with permissions to write to CloudWatch Logs. 3. Create the VPC Flow Log, specifying the log group and IAM role. 4. Verify that flow log records are delivered to the log group. 5. Analyze the logs using CloudWatch Logs Insights.

  Why this is correct

  This is the correct sequence because the log group must exist before the flow log is created, and the IAM role must be available to grant permissions. After creating the flow log, verification ensures logs are flowing, and analysis is the final step.

• ✗

  1. Create an IAM role with permissions to write to CloudWatch Logs. 2. Create a CloudWatch Logs log group. 3. Create the VPC Flow Log, specifying the log group and IAM role. 4. Verify that flow log records are delivered to the log group. 5. Analyze the logs using CloudWatch Logs Insights.

  Why it's wrong here

  This order is incorrect because the log group should be created before the IAM role? Actually, the IAM role can be created before the log group, but the typical order is log group first. However, the more critical mistake is that some users might think the role must come first; but the flow log creation requires both, so order of 1 and 2 doesn't affect functionality. However, best practice is to create the log group first. Still, this is plausible but not the recommended order. Explanation: While technically both orders work, the standard approach is to create the log group first to ensure it exists before configuring permissions.

• ✗

  1. Create the VPC Flow Log, specifying a log group and IAM role. 2. Create a CloudWatch Logs log group. 3. Create an IAM role with permissions to write to CloudWatch Logs. 4. Verify that flow log records are delivered to the log group. 5. Analyze the logs using CloudWatch Logs Insights.

  Why it's wrong here

  This is incorrect because the flow log cannot be created before the log group and IAM role exist. The flow log creation will fail if the log group or role is missing.

• ✗

  1. Create a CloudWatch Logs log group. 2. Create the VPC Flow Log, specifying the log group but without an IAM role. 3. Create an IAM role with permissions to write to CloudWatch Logs. 4. Verify that flow log records are delivered to the log group. 5. Analyze the logs using CloudWatch Logs Insights.

  Why it's wrong here

  This is incorrect because the flow log requires an IAM role at creation time. Without it, the flow log creation will fail. The role must be created before the flow log.
